I am not very experienced with Windows platforms, but I thought that command should be available there.  Have you got your PATH set properly so cl is on the PATH?

I suspect Arjen can answer this question a lot better.


"cl" is the name of the MSVC/C++ compiler. I suspect that some component (Qt5, cairo or pixman) - at least in the configuration you were using - assumes that you have that compiler installed and want to use it to build that component. Does the out of make indicate which component is using "cl"?

Arjen

On MinGW, and if so details please?  (If on Cygwin, you should be
using the Cygwin install of Qt, and the directions are different
than I gave for MinGW.)

The context of your question about cl seemed to indicate you were
trying to use the cairo device for a MinGW build so my reply assumed
that.

I am not surprised that cl does not exist for the Cygwin case since
Cygwin tries to be as close as possible to the Unix platform case and
cl is a native Windows application.  With some fairly minor caveats
Arjen has had some good success on Cygwin with the cairo device
driver.  But he installed the Cygwin version of the pango/cairo subset
of GTK+ and you must do that as well for the Cygwin case.  I am now
wondering if you attempted to use instead a downloaded native Windows
versions of those libraries (that might be suitable for MinGW but
never for Cygwin), and this was the source of error messages about cl?

If/when you reply, please be explicit each time whether you are
running a build on MinGW or Cygwin and please also give all error
details including cmake options such as the generator you used, and
cmake output which normally gives exact locations where CMake found
libraries.  Also, for each such library found by CMake you should
double-check whether it is a native Windows version you downloaded or
a Cygwin library that is installed officially with the Cygwin
installer and adjust your PATH and other environment variables
carefully so cmake always finds MinGW libraries on the MinGW platform
and Cygwin libraries on the Cygwin platform.

Re: [Plplot-general] Including cairo driver

[Walt B. <wal...@gm...>]

Thanks again to both of you.

Alan's suggestion to build with Qt blew up.

I have what I thought was a complete install
of cygwin and there is no "cl".

I tried Darius' suggestion to use TDM. Rebuilt it
and it gives exactly the same results as the Mingw
build.

Don't know why things don't work for me. It
could not possibly be operator error :-).

BUT, Darius' suggestion to use Inkscape is good.
I used it to convert an svg file to png and pdf
(which is readable by Adobe). I think that is
where I will leave things.

Hi Walt:

I hope you don't mind that I am replying on the list, but I think that is where
this conversation belongs, and I hope you reply to the list as well.

(1) Set the PATH environment variable appropriately so that the qmake
application from Qt5 is on your PATH.  (Unlike the Qt4 case, the
actual Qt5 find procedure does not use this application any more, as
far as I know, but if the PATH is setup this way, then the Qt5 find
procedure should know where to find what it actually needs.)

(2) Use the cmake option -DPLPLOT_USE_QT5=ON for the PLplot build.


(3) Use the svn trunk version of PLplot.

I am not very experienced with Windows platforms, but I thought that
command should be available there.  Have you got
your PATH set properly so cl is on the PATH?

I suspect Arjen can answer this question a lot better.

Re: [Plplot-general] Including cairo driver

[Walt B. <wal...@gm...>]

Thanks for all of that explanation.

At some point I will try to build pango/cairo and Qt5
from scratch using Mingw only. But obviously I am
not as good at this kind of thing as you guys.

Maybe something to think about for the future if you
can get somebody with MS Windows experience to
do it--provide a Windows binary package. Most of the
things I use come that way (Mingw, GTK, Code::Blocks,
etc.) That makes it a whole lot easier for people like
me who are not so good at building things from scratch.

Anyway, thanks again.

I think that is an extremely likely explanation.  But if you are
careful (in the way I stated previously to you) to set environment
variables so that for MinGW you stick completely to MinGW dependencies
and for Cygwin you stick completely to Cygwin dependencies, you should
be able to build PLplot under both Cygwin and MinGW on one box.

> I still can't get cairo, but that is OK.

The PLplot dependencies on external libraries are currently a big
issue for MinGW.  To get pretty close to what you have on Cygwin, you
would need at least binary versions of Qt5 and the pango/cairo subset
of the GTK+ stack of libraries which are needed by our "qt" and cairo
device drivers.  Those are our two best such device drivers and they
implement a substantial number of devices between them including those
which implement the PNG, JPEG, and PDF formats as well as many other
formats. If you download binary versions of Qt5 and pango/cairo it is
unlikely that either/both are going to be ABI consistent with the
single MinGW version you use to build PLplot.  So really the only good
choice is to build the external libraries yourself with exactly the
same MinGW version you use to build PLplot.  That should be
straightforward to do because those external libraries are all
open-source with well-defined procedures for building with MinGW on
Windows.  But it is not an easy task because the Windows build lore
that is required for each different piece of software is often hard to
dig out of the google noise.  I am working to fix that situation with
the epa_build idea (see below), but for now those who use MinGW
normally settle for an extremely light-weight version of PLplot
without the cairo, qt, and wxwidgets device drivers which means
essentially only the ps, svg, and wingcc devices are available for
MinGW.

See explanation above about why the MinGW version of PLplot is so
limited for now.  I do have a subproject of PLplot called epa_build
(see cmake/epa_build/README) which allows you to conveniently build
all PLplot dependencies (other than octave which I have not epa_build
configured yet) on Unix.  And all aspects of the epa_build approach
should eventually work on MinGW as well.  In fact, every external
library package that epa_builds on Unix also epa_builds on MinGW
except for Qt5 and the pango/cairo subset of GTK+. Digging out the
Windows lore on how to build those packages takes some effort as well
as a lot of build experimentation, and, in fact, I cannot do that
build experimentation myself because I don't have access to Microsoft
Windows. So I am currently looking for someone who does have such
access who is willing to do the work (with backup help from me) to get
Qt5 and pango/cairo epa_build to MinGW.  That is a really important
project from the PLplot prospective since it will transform MinGW from
a light-weight PLplot platform to a powerful PLplot platform.

Meanwhile, Cygwin already has all the PLplot dependencies available in
an ABI consistent way.  And Arjen has run with this possibility and
demonstrated that essentially all PLplot functionality works on
Cygwin.  So that powerful PLplot platform is the one I recommend to
our Windows users for now if they need more than just PostScript or
SVG results.

[Plplot-general] 1st Call For Papers, 21th Annual Tcl/Tk Conference 2014

[Andreas K. <and...@ac...>]

21'th Annual Tcl/Tk Conference (Tcl'2014)
http://www.tcl.tk/community/tcl2014/

November 10 - 14, 2014
Embassy Suites Downtown
Portland, Oregon, USA

Important Dates:

Abstracts and proposals due     Sep  8, 2014
Notification to authors         Sep 22, 2014
Author materials due            Oct 20, 2014
Tutorials start                 Nov 10, 2014
Conference starts               Nov 12, 2014

[[ 
        Registration is open.
]]

Email Contact:                tcl...@go...

Submission of Summaries

Tcl/Tk 2014 will be held in Portland, Oregon, USA from November
10 - 14, 2014. The program committee is asking for papers and
presentation proposals from anyone using or developing with Tcl/Tk
(and extensions). Past conferences have seen submissions covering a
wide variety of topics including:

* Scientific and engineering applications
* Industrial controls
* Distributed applications and Network Managment
* Object oriented extensions to Tcl/Tk
* New widgets for Tk
* Simulation and application steering with Tcl/Tk
* Tcl/Tk-centric operating environments
* Tcl/Tk on small and embedded devices
* Medical applications and visualization
* Use of different programming paradigms in Tcl/Tk and proposals for new
  directions.
* New areas of exploration for the Tcl/Tk language

Submissions should consist of an abstract of about 100 words and a
summary of not more than two pages, and should be sent as plain text
to <tclconference AT googlegroups DOT com> no later than August 5,
2014. Authors of accepted abstracts will have until September 2, 2014
to submit their final paper for the inclusion in the conference
proceedings. The proceedings will be made available on digital media,
so extra materials such as presentation slides, code examples, code
for extensions etc. are encouraged.

Printed proceedings will be produced as an on-demand book at lulu.com

The authors will have 25 minutes to present their paper at the
conference.

The program committee will review and evaluate papers according to the
following criteria:

* Quantity and quality of novel content
* Relevance and interest to the Tcl/Tk community
* Suitability of content for presentation at the conference

Proposals may report on commercial or non-commercial systems, but
those with only blatant marketing content will not be accepted.

Application and experience papers need to strike a balance between
background on the application domain and the relevance of Tcl/Tk to
the application. Application and experience papers should clearly
explain how the application or experience illustrates a novel use of
Tcl/Tk, and what lessons the Tcl/Tk community can derive from the
application or experience to apply to their own development efforts.

Papers accompanied by non-disclosure agreements will be returned to
the author(s) unread. All submissions are held in the highest
confidentiality prior to publication in the Proceedings, both as a
matter of policy and in accord with the U. S. Copyright Act of 1976.

The primary author for each accepted paper will receive registration
to the Technical Sessions portion of the conference at a reduced rate.

Other Forms of Participation

The program committee also welcomes proposals for panel discussions of
up to 90 minutes. Proposals should include a list of confirmed
panelists, a title and format, and a panel description with position
statements from each panelist. Panels should have no more than four
speakers, including the panel moderator, and should allow time for
substantial interaction with attendees. Panels are not presentations
of related research papers.

Slots for Works-in-Progress (WIP) presentations and Birds-of-a-Feather
sessions (BOFs) are available on a first-come, first-served basis.
WIP slots can be reserved like any paper proposal. BOF slots will be
managed on-site. All attendees with an interesting work in progress
should consider reserving a WIP slot.

Registration Information

More information on the conference is available the conference Web
site (http://www.tcl.tk/community/tcl2014/) and will be published on
various Tcl/Tk-related information channels.

        Registration is open.

[Plplot-general] Stopping a plot after using "np"

[Kyle B. <kw...@ua...>]

I've written a few plots where I like to use the no pause "np" with
double buffering "db". Is there a way to stop the no pause feature? 
Suppose I had data that I wanted to continuously update and plot inside
a loop, then when breaking out of the loop, have the plot stay static?

I've been using the setopt("np",true") and setopt("db","true") to enable
updating inside a loop.  I've tried using resetopt and clearopt, as well
as using setopt and setting np/db back to false, but have had no luck in
being able to keep the plot up.

I'm using c/c++, with mainly xwin and wxwidgets.

Thanks,

Kyle Bentley

OK.  The _plplotcmodule_fixed target is a relatively recent addition
(that allows us to use UTF-8 Python doc strings for all the commands
in our Python binding). Please try the svn trunk version instead of
5.10.0.

Could you be more explicit about exactly what you did, and the error
messages that were generated?  I was careful to verify the commands I
suggested so those suggested C and Python tests work for me, and I am
quite surprised they do not work for you.

Thanks for this clarification of your needs.  In answer to your
specific question above, the example program does not exit before you
exit the plot, but I suggest you verify that yourself by running the
exact C and Python tests I recommended (i.e., follow up on why you
could not reproduce those simple test cases) to make absolutely sure
we are talking about the same things.

Re: [Plplot-general] Does plplot have an equivalent of PGPLOT's /xserve device?

[Thomas M. <t.r...@wa...>]

Thanks for your message Alan. I could run "make xwin" but the subsequent
commands failed for some reason. Note however that I am able to run the
Python version of plplot successfully already. I am not sure that what you
describe is quite it. Does the example program exit before you exit the
plot? (so that you could e.g type "ls" in the terminal from which you ran
the example program, etc.) My guess is no. The equivalent in PGPLOT is the
/xwindow device where it asks you to "hit <cr> for the next page:" and once
you do this, the plot disappears and program execution continues (exiting
if there is nothing left to do). The /xserve device does not produce the
"hit <cr>" message but the program continues executing and the plot
persists. The equivalent with plplot would be that the plot appears, the
program exits but the plot still exists. As I understand /xserve, an
independent server is created which carries on running even after the
program that created it has exited.  This for example allows you to run
another script and write a new plot into the plot window, or if you want
open and write to a new window (by specifying "2/xserve", "3/xserve" etc).

Here is the minimal Python example of where it differs relative to PGPLOT's
/xserve:

plsdev("xwin")
plinit()
plspause(False)
plend()

[rest of code]

This continues executing rest code, but no plot is produced. If I do
instead:

plsdev("xwin")
plinit()
plend()

a plot is produced, but has to explicitly exited before program execution
resumes.

P.S.  I forgot to mention my examples work only if you use
-DBUILD_TEST=ON as a cmake option.

Hi Tom:

I have been following your conversation with Arjen with interest, and
I think what you describe above is exactly what we provide.  But I
might be interpreting what you said above incorrectly so let me make
clear what we provide with an exact example.

In the build tree, if I build the xwin device and one of the simplest
examples with the following commands:

# Create xwin device and all its dependencies
make xwin
# Create a particular C example and all its dependencies
make x00c

then when I run

examples/c/x00c -dev xwin

the plot persists on the screen and the C example does not quit.  In
fact, I can resize that plot so it does remain active until I exit
from it (by hitting the enter key or clicking on the button to destroy
the X window).  So it appears to me this default behaviour of the xwin
device is exactly what you described above.

You expressed and interest in Python so here is the equivalent there

# Create xwin device and all its dependencies
make xwin
# Create Python binding for PLplot
make _plplotcmodule_fixed
# Populate build tree with python examples
make python_examples

Then run

examples/python/x00 -dev xwin

and that plot has the same desired characteristics as the C version above.

Will you try either the C version or Python version of the concrete example
above, and let us know what (if anything) the difficulty might be?

[Thomas M. <t.r...@wa...>]

Yes, I had thought of this, but I consider the need to invoke a viewer for
each plot as quite an
inconvenience and prefer just to save to disk when I really want to
otherwise I will end up generating
piles of one-off plots.

Re: [Plplot-general] Does plplot have an equivalent of PGPLOT's /xserve device?

[Arjen M. <Arj...@de...>]

Hi Tom,

I have been thinking of a completely different solution:

-        Save the pictures in a file, like a PNG or a PDF file

-        Run an appropriate viewer from within your program (in the background)

This way:

-        The computations can continue without involving multiprocessing

-        The pictures remain visible and can even be rerieved afterwards

Hi Tom,

Hm, you want to have several independent windows then. I have no particular experience with that sort of a set-up. I do think PLplot was designed with that in mind and I will have to leave it to others to help you with this.

One thing that you would have to deal with is merging two different programming models – the event-driven one for the graphics and the procedural one for your computations. That is possible, for instance via multiprocessing, but I am not entirely sure what the easiest way would be. Perhaps others have looked into this already. It is intriguing though …

Hi Arjen,

thanks for your reply. plflush *without* a plend sort of works with "tk", but has significant problems -- see below. What I want to do is not quite as you summarise; sorry for not being clear. Its not so much that I want to resume plotting -- I imagine plflush would be good for this -- but I want the plot to finish but then to persist and not simply disappear. I sometimes have multiple such plots in windows on my screen, potentially produced by independent scripts. When I am done with them I can click the "X" at the top-right to get rid of them. I have not managed to replicate this way of working with plplot. When I used plflush without plend, my test script exited and the plot remained (with "tk" but not "xwin"). I ran the script a couple of times and produced two such plots. However, hearing my laptop's fan crank up, a look with "top" revealed two processes called "plserver" each running at 120% CPU [server talking to non-existent script perhaps?], so I think the absence of "plend" was not good, and this solution is not workable.

(As I do not know PGPLOT, I want to make sure I understand it.) plspause() will do that indeed, but the graphics buffer may get in the way.

Try using plflush() at the end of drawing the graph. I have not tried it, but I think that will help.

Regards,

Arjen

Subject: [Plplot-general] Does plplot have an equivalent of PGPLOT's /xserve device?

Hello, I am new to plplot, but I am trying to check it for a number of applications I have in mind within C++ and Python codes as a replacement for PGPLOT which I have used for years.  I am starting with the Python binding to explore plplot's features. The interactive device I use most of all with PGPLOT is "/xserve" which allows you to generate a plot that persists after a program / script exits and returns control to the terminal. I use this feature all the time. Within long running programs, it allows me to generate plots which I can look at while the program continues doing something else. With plplot's xwin or tk, I can get a plot that persists, but it seems to block until I have actively quitted it. I experimented with calling plspause(False) just before plend but then the plot just flashes briefly with tk and does not appear at all with xwin.
I feel I am missing something obvious, but haven't found it yet. Thanks in advance for any help,
tom

[Arjen M. <Arj...@de...>]

Hi Tom,

Hm, you want to have several independent windows then. I have no particular experience with that sort of a set-up. I do think PLplot was designed with that in mind and I will have to leave it to others to help you with this.

One thing that you would have to deal with is merging two different programming models – the event-driven one for the graphics and the procedural one for your computations. That is possible, for instance via multiprocessing, but I am not entirely sure what the easiest way would be. Perhaps others have looked into this already. It is intriguing though …

Arjen

Hi Arjen,

thanks for your reply. plflush *without* a plend sort of works with "tk", but has significant problems -- see below. What I want to do is not quite as you summarise; sorry for not being clear. Its not so much that I want to resume plotting -- I imagine plflush would be good for this -- but I want the plot to finish but then to persist and not simply disappear. I sometimes have multiple such plots in windows on my screen, potentially produced by independent scripts. When I am done with them I can click the "X" at the top-right to get rid of them. I have not managed to replicate this way of working with plplot. When I used plflush without plend, my test script exited and the plot remained (with "tk" but not "xwin"). I ran the script a couple of times and produced two such plots. However, hearing my laptop's fan crank up, a look with "top" revealed two processes called "plserver" each running at 120% CPU [server talking to non-existent script perhaps?], so I think the absence of "plend" was not good, and this solution is not workable. If I stick plend back in, then I get the same instant disappearance of the plot when I set plspause(False) whether I use plflush or not, unsuprisingly I think, as I imagine plend flushed the graphics.

Re: [Plplot-general] Including cairo driver

[Arjen M. <Arj...@de...>]

Hi everyone,

This turned out my mistake: the shell script I used held a long list of arguments, which included - beyond the right margin of the screen - options to turn off the cairo devices. Once I realised that, there was no particular problem in building PLplot with cairo support.

The thing that threw me off guard was the appearance of one or two messages regarding cairo - the most relevant one: wincairo not being supported on Cygwin. I will change the logic, so that this will only get printed if you ask for that device on Cygwin. Seems more appropriate to me.

Regards,

Arjen

Hi Walt,

I will have to investigate this further, which may be both hindered and helped by the fact that I had to reinstall my computer (sigh), but one thing that I noticed is that the PKG_CONFIG_PATH is set up according to the native Windows format.

Could you try with:

set PKG_CONFIG_PATH=/cygdrive/c/walt:/cygdrive/c/FortranTools/gtk/lib/pkgconfig

(Or within Cygwin: setenv ....)

While I am not at all sure this is the problem, it is definitely something to look into - Cygwin normally likes the UNIX better.

As for the generator: yes, use "UNIX Makefiles". Not sure again if it matters, but just to exclude possible problems later on.

That definitely should not happen so I suspect there is something wrong with the way you are using CMake or the version of CMake that you are using.

I don't have any experience with Cygwin.  Arjen is our expert for that platform so I assume he will correct anything I say once he becomes aware of this thread (probably next week since he rarely looks at PLplot mailing lists on weekends).  But until he can give definitive replies to your questions, my guess is you are not using the correct generator for Cygwin.  If I recall correctly what Arjen did, I think you should be using the "Unix Makefiles" generator instead. Also, one other Cygwin-related tip I happen to be aware of is make sure you are using a cmake version that is installed from the Cygwin site rather than a native Windows version of cmake that you can download from the Kitware site but which does not work correctly on Cygwin.

In general, Arjen, has gotten most of PLplot to work without issues on Cygwin so if those two suggestions don't help, don't give up, and I am sure that Arjen will eventually be able to help you.

That definitely should not happen so I suspect there is something wrong with the way you are using CMake or the version of CMake that you are using.

I don't have any experience with Cygwin.  Arjen is our expert for that platform so I assume he will correct anything I say once he becomes aware of this thread (probably next week since he rarely looks at PLplot mailing lists on weekends).  But until he can give definitive replies to your questions, my guess is you are not using the correct generator for Cygwin.  If I recall correctly what Arjen did, I think you should be using the "Unix Makefiles" generator instead. Also, one other Cygwin-related tip I happen to be aware of is make sure you are using a cmake version that is installed from the Cygwin site rather than a native Windows version of cmake that you can download from the Kitware site but which does not work correctly on Cygwin.

In general, Arjen, has gotten most of PLplot to work without issues on Cygwin so if those two suggestions don't help, don't give up, and I am sure that Arjen will eventually be able to help you.

Re: [Plplot-general] Including cairo driver

[Arjen M. <Arj...@de...>]

Hi Walt,

I will have to investigate this further, which may be both hindered and helped by
the fact that I had to reinstall my computer (sigh), but one thing that I noticed is
that the PKG_CONFIG_PATH is set up according to the native Windows format.

Could you try with:

set PKG_CONFIG_PATH=/cygdrive/c/walt:/cygdrive/c/FortranTools/gtk/lib/pkgconfig

(Or within Cygwin: setenv ....)

While I am not at all sure this is the problem, it is definitely something to look into - Cygwin
normally likes the UNIX better.

As for the generator: yes, use "UNIX Makefiles". Not sure again if it matters, but just to
exclude possible problems later on.

Regards,

Arjen

[Plplot-general] Including cairo driver

[Walt B. <wal...@gm...>]

I have built plplot for the first time and successfully
run most of the Fortran examples by selecting the
wingcc option. Very nice stuff!

Now, I would like to run the GTK-Fortran examples that
use the cairo driver. I looked at lots of posts and docs,
but nothing I have tried works. In one place in the
documentation, it says something like : To add a
device driver, set the parameter ...   What parameter?
Where is it set?

Here is some information about what I tried. I would be
happy to provide more, but don't really know where the
problem is.

Windows 7 with cygwin.

cmake build command:
C:\"Program Files (x86)"\"CMake 2.8"\bin\cmake -G "MinGW Makefiles"
-DDEFAULT_NO_BINDINGS=ON -DENABLE_f95=ON
-DCMAKE_INSTALL_PREFIX=install ..

Here are some of the lines from the cmake output:

-- SWIG was not found. Please specify Swig executable location
   . . .
-- checking for module 'pango'
--   found pango, version 1.30.1
-- WARNING: pkg-config does not find pango.

=============================================
Do I need SWIG?
Why does it say it can't find pango when it just said it *did*
find pango?

I tried running cmake with -DPLD_wincairo. No difference.

Help would be appreciated. Thanks.

And if I can get this working, I would like to be able to generate
things like jpeg files.
