[Plplot-general] install problems

[M. F. <mfr...@se...>]

I am trying to install plplot 5.0.3-4
on Linux Mandrake 8.0 and get the following

[root@]# rpm -i plplot-5.0.3-4.i386.rpm
error: failed dependencies:
        libgd.so.1.8   is needed by plplot-5.0.3-4


I then tried
[root@]# rpm -i gd-1.8.1-4mdk.i586.rpm
file /usr/lib/libgd.so.1 from install of gd-1.8.1-4mdk conflicts with file
from package libgd1-1.8.4-3mdk

I checked
[root@]# ls /usr/lib/libgd.*
/usr/lib/libgd.so.1@  /usr/lib/libgd.so.1.8.4*

How do I resolve this(these) dependency problem(s)?

Thanks.

Martin

I forgot this one. Sorry for the delay--of course you don't need it=20
anymore :).

If your images are small and monocrome, plshade() with a gray=20
colormap works OK. With a 349x239 color image *octave* took 5 sec to=20
draw it. Of course, you can code it in other language.

octave-2.1.34:2> img =3D jepg2gray("~jcard/pic/pic9.jpg");
octave-2.1.34:3> size(img)
ans =3D

  349  239

octave-2.1.34:4> plcolormap (gray);
octave-2.1.34:10> tic; t=3Dcputime; shade(img); cputime-t, toc
ans =3D 2.5400=20
ans =3D 4.6722

2.5 sec of CPU, 4.7 sec of wall clock.

The (very old) used functions:
------------------------------------------------
function gray =3D jepg2gray(file)

o_file =3D tmpnam;
system(sprintf("djpeg %s > %s",file, o_file));

gray =3D ppm2gray(o_file);

system(sprintf("rm -f %s", o_file));
endfunction
-----------------------------------------------------
function gray =3D ppm2gray(file)

# ppm2gray: raw/ascii ppm picture to gray image format
#
# xv-3.10a stores each header line on a separate line, \n separated
# giftoppm is identical to xv
# in xloadimage-4.0 there is only one header line, parameters=20

[Plplot-general] ftp site has been cleared

[Alan W. I. <ir...@be...>]

PLplot 5.0.0 was released in May of last year as a tarball
(plplot-5.0.0.tar.gz) and has been residing in our SourceForge ftp space
ever since.  In contrast the subsequent PLplot 5.0.1 through 5.0.4 were
released using the SF file release mechanism.  These releases include
tarballs and rpms and are accessible at our file release area
(http://sourceforge.net/project/showfiles.php?group_id=2915).  To
consolidate all our SF releases in one place and also because SF is shutting
down their old ftp server, I have moved plplot-5.0.0.tar.gz to the file
release area.

Note 2000 May 12 is an extremely important date in PLplot history, but we
have come a long way since that first release in the 5.0.x series with many
new features and bug fixes.  Thus, for everyday use PLplot 5.0.4 is the
recommended version.

submit a patch and become a plplot developper :-) We need you.

Hint: "fgrep debug_on *.tcl" in the plplot tmp directory (advantages=20
of the flat model :-)

What you mean? In what language (or language bindings) do you intend=20
to work? plSetOpt() is a library call to setup an option (see=20
plargs.c). If you start one of the C demos, say x01c, and type ./x01c=20
-showall -h, you see two options:

*  -plwindow name       Name of PLplot container window (tk or dp=20
driver)
*  -tk_file file        file for plserver (tk or dp driver)

These happen automatically, there is no special code in x01c.c.

| 3. When is the "plw_start" procedure in
| (plplotdir/lib/plplot5.0.4/tcl/plwidget.tcl) called? What I mean is
| what API command calls it. I looked around but couldn't find out.

That's not an API entry. Again:

bash-2.04# fgrep plw_start *.tcl
plclient.tcl:# plw_start_proc   proc to manage the plframe widget
plclient.tcl:   plw_start_proc plw_end_proc \
plclient.tcl:    set plw_start_proc             plw_start
plwidget.tcl:# plw_start
plwidget.tcl:proc plw_start {w} {
plwidget.tcl:   catch after_plw_start

bash-2.04# fgrep plw_start *.c =20
tk.c: *    $plw_start_proc              Does any remaining startup=20
necessary
tk.c:    server_cmd( pls, "$plw_start_proc $plwindow", 1 );

( you can also build a tags file (etags *.c *.h *.tcl) open (x)emacs,=20
and find the tag you want, browsing throug the code--but I'm not a=20
sofisticated user :)

So, it looks like plw_start is called at tk.c, the tk driver source=20
code.
But tk.c is not an easy code to digest; it is a standard driver that=20
at driver initialization time atach to a tk interpreter, than=20
fork/exec (launch) the plserver, establish a communication link=20
between the attached tk and plserver, and then use that channel to=20
send/receive commands to plserver. I'm not shure that this completely=20
correct.
It looks like there can exist two kinds of links: either tk standard=20
"send", when the program that uses the tk driver is on the same X=20
display that plserver, and a network socket implemented with "dp",=20
when the programs are running on diferent machines (but I think that=20
"dp"--a tcl extension-- is not in use anymore--not shure again).

| 4. I have a suggestion for a small change in the procedure
| "plw_start" (hope this is the right list). The change and reason
| for it are specified at the end of this mail.
|
| -------------------------------------------
|
| From what I've been able to tell, the most important procedures

| are:
|
| 1. plserver_init (plplotdir/lib/plplot5.0.4/tcl/plserver.tcl) -
| Sets up the top menubar with the File and Help menus
| =A0 =A0 =A0 =A0|| =A0 =A0 =A0 calls
| =A0 =A0 =A0 =A0v
| 2. plstdwin (plplotdir/lib/plplot5.0.4/tcl/pltools.tcl) - Runs the
| pldefaluts and plconfig procedures to set up the options and sets
| the minimum window size and geometry.
|
| =A0 =A0 =A0 =A0 =A0(don't know who calls this, probably plinit)
| 3. plw_create (plplotdir/lib/plplot5.0.4/tcl/plwidget.tcl)
| =A0 =A0 =A0 =A0|| =A0 =A0 =A0 calls
| =A0 =A0 =A0 =A0v
| 4. plxframe (plplotdir/lib/plplot5.0.4/tcl/plwidget.tcl) - Creates
| a container frame (unless already specified) and puts the plot_menu
| and plframe (for the actual plot) inside it.
|
| =A0 =A0 =A0 =A0 =A0(don't know who calls this, probably plinit)

This is the important part, I think

| 5. plw_start (plplotdir/lib/plplot5.0.4/tcl/plwidget.tcl) - Packs
| the container frame that was either specified by the user or
| created by "plxframe". Tells the client that the widget is ready.
| Calls a procedure "after_plw_start" which is optional code the user
| can write if he needs to execute anything after the driver
| initialization is done.
|
| ------------------------------------------
|
| When the "plinit" command is called with the "tk" driver the
| procedure "plxframe" is used. This procedure creates a "container"
| frame and within that frame are the "plot_menu" (if enabled) and a
| "plframe".
|
| There is the option to specify a tcl script and an empty frame for

| "tk" driver DOESN'T CHECK whether the specified container frame has

| previoulsy mapped with a geometry manager other than PACK it causes
| the process to lock up.

Roberto problem is, if I undestood correctly (we have been talking=20
off-list): "if I write a tk interface using my prefered geometry=20
manager, the "grid", and let an empty frame on it, where I want the=20
plots to go--using plSetOpt ("plwindow", plot_frame)--then the=20
program blocks, because plserver *packs* the frame that is already=20
"grided".

| So here there are two options:
|
| a) Make sure all the widgets that are siblings of the specified
| "container" frame are managed with PACK.
|
| b) Modify the procedure that initializes the "tk" driver to check
| whether the specified container frame has been mapped or not before
| packing it.
|
| The procedure in charge of doing the packing is "plw_start" which
| is in the "plplotdir/lib/plplot5.0.4/tcl/plwidget.tcl" file. The
| change is as follows:
|
| [old]
| # Manage widget hierarchy
| =A0 =A0 pack append [winfo parent $w] $w \
| =A0 =A0 =A0 =A0{bottom expand fill}
|
| =A0 =A0 update
|
| [new]
| # Manage widget hierarchy
| =A0 =A0 if {! [winfo ismapped $w]} { =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0=
 =A0 =A0 =A0 =A0 =A0<---
| only change pack append [winfo parent $w] $w \
| =A0=A0=A0=A0=A0=A0=A0=A0 =A0 =A0 =A0 =A0{bottom expand fill}
| =A0 =A0 }
|
| =A0 =A0 update
|

It does not work for me, if I try "./x01c -dev tk", I get

invalid command name "=A0"
    while executing
"=A0"
    (procedure "plw_start" line 6)
    invoked from within
"plw_start .x01c"
    ("after" script)

Haven't you done any other changes? The changes I made:

bash-2.04# diff -c plwidget.tcl plwidget.tcl.new
*** plwidget.tcl        Mon Sep 10 16:51:49 2001

How can I do the same without Octave?

[Plplot-general] yPlot-1.1.0 released!

[Alan W. I. <ir...@be...>]

yPlot is riding on the shoulders of PLplot as it grinds relentlessly toward
world domination....;-)

What: yPlot 1.1.0 release (as a tarball and RedHat 6.2 rpm's).
Where: http://sourceforge.net/projects/yplot (click on file releases).
When: Now
Why: Many bugs fixed and many new features
Who: Alan and Conrad

yPlot is a Yorick front-end to PLplot that combines the best features of
both.  You have all the power and ease-of-use of Yorick at your finger-tips
combined with the rich scientific plotting API of PLplot.  This yPlot
release includes a tutorial and large number of illustrative examples that
should get you plotting sophisticated publication-quality scientific plots
in short order.

This version of yPlot is based on PLplot-5.0.4 (see
http://sourceforge.net/projects/plplot), which is a huge step up in terms of
documentation, bug fixes, and features from the PLplot-4.99 snapshot that
yPlot was based on before. In addition, yPlot-1.1.0 significantly extends
the yPlot API to include virtually all the common PLplot API. For example,
the new release includes new yPlot example scripts that can be used to mimic
the results of virtually all the PLplot x??c examples including shade plots
and 3D shaded-surface plots.

Please see the CHANGES file for a summary of all the bug-fixing, API
changes, documentation improvements, and API extensions that have gone into
this release.

Good Plotting!

Alan

Ok, I did this in xwin.c in plD_init_xw() after 
    pls->plbuf_write = 1;       /* Activate plot buffer */
    pls->nopixmap = 1;

Now I get :
Enter device number or keyword: 1
X protocol error: error=8 request=1 minor=0
X protocol error: error=3 request=18 minor=0

Re: [Plplot-general] PLplot 5.0.4 is released

[Alan W. I. <ir...@be...>]

My understanding is that ftp area will not be supported much longer by
sourceforge (for example, new projects don't get one) so I haven't bothered
with it for any release I was associated with.

In any case I would like to stick strictly to the file release area for thi=
s
and all future releases made via sourceforge because of its several
advantages.  It is directly accessible from our project page, it is
organized, and there is a possibility of writing release notes (although I
haven't done so).  Another big advantage is you can keep track of download
statistics.  For example, the tarballs for 5.0.1, 5.0.2, and 5.0.3, have
been downloaded 244, 485, and 881 times.  It is early days for the 5.0.4
tarball, which currently stands at 47 downloads, but it would be great to
see the downloads approximately double again for that version.

[Plplot-general] PLplot 5.0.4 rpm's for RH 6.2

[Alan W. I. <ir...@be...>]

I have just file released plplot-5.0.4-1.i386.rpm and plplot-5.0.4-1.src.rpm
at
http://sourceforge.net/project/showfiles.php?group_id=2915&release_id=39317.

These rpms are suitable only for RH 6.2, because that is the latest
rpm-based platform I have access to.  However, the spec file in the source
rpm should be easy to modify for other more modern distributions.

[Plplot-general] X errors for HPUX

[Alan W. I. <ir...@be...>]

Osman, I am putting your question and Maurice LeBrun's response which was
made on the development list to the plplot-general list where I think they
belong. So Maurice may have fixed this, but you will have to try the CVS
version (or try setting pls->nopixmap=1) to see.

Maurice said:

 Some kind of problem with the pixmap creation.
 
 The code traps the case where the pixmap allocation fails because of lack of
 memory.  In that case the X driver reverts to redrawing the entire window on
 expose events since it can't refresh from a pixmap.  The error the server's
 supposed to return if there's insufficient memory is a BadAlloc.  It may be
 that the server is returning a bad error code (the PR on sourceforge lists
 it as a BadDrawable), which the X driver doesn't like.
 
 We can try treating all pixmap creation errors the same to see if this helps.
 I'll commit the change shortly.  Until then, people experiencing problems can
 try setting pls->nopixmap=1 (pls being the current stream), which turns off
 the pixmap code.

[Plplot-general] PLplot 5.0.4 is released

[Alan W. I. <ir...@be...>]

PLplot is still grindly relentlessly toward world domination....;-)

What: PLplot 5.0.4 release (as a tarball---rpm's and deb's to come)
Where: http://sourceforge.net/projects/plplot (click on file releases).
When: Now
Why: Bug fixing and new features (especially portrait mode)
Who: Alan, Andrew, Geoffrey, Jo=E3o, Maurice, Rafael, and Vince

Important Changes:=20

(1) Default orientation for the ljii, ljiip, psc, ps, and pstex drivers has
been rotated from seascape (upside-down landscape) by 180 deg to landscape.
With this change no special 180 deg latex rotations will be required to get
true landscape mode (top of the plot on the left of the page as opposed to
on the right of the page for seascape mode).  If you still require seascape
for some reason for these drivers, use the -ori 2. command-line option or
else use plsdiori(2.) or plsetopt("ori", "2.").

(2) The installation location for examples has been changed to
$prefix/lib/plplot<ver>/examples to be in better conformance with the FHS.

Important Bug fixes:

(1) Many improvements to the octave front end.

(2) Many improvements to the xfig driver.

(3) If the overall aspect ratio is changed by the -geometry, -a, or -portra=
it
options or else by the combination of the -ori 1 and -freeaspect options, t=
he
character aspect ratio remains unaffected.  For example, when the overall
aspect ratio is changed now, circular symbols remain circular rather than
turning into ellipses as in the old code.

(4) Software pattern fills now rotate correctly with the rest of the plot
when the -ori option is used.  This fix affects all drivers (e.g., xwin,
psc) which do not handle their own pattern fills.  (Previously the rotation
angle for software pattern fills was mistakenly doubled by two calls to the
orientation transformation routine.)

Important New Features:

(1) Portrait mode.  Use the -portrait option on the command line or else
plsetopt("portrait", "") to get this option which only currently affects th=
e
ljii, ljiip, ps, psc, and pstex drivers.  This option is especially useful
for yplot, the yorick front-end to PLplot.  yplot previously maintained
separate (=3D=3D> hard-to-maintain and buggy) portrait versions of the psc,=
 ps,
and ljiip drivers.  Those will no longer be necessary with this PLplot
core change, and in fact portrait mode is now available for a much wider
range of drivers.

(2) -drvopt command-line option (or else use plsetopt("drvopt","option")).
This allows setting options for particular drivers.  For example, the
-drvopt text option for the psc or ps driver allows use of Adobe fonts (Thi=
s
is poorly documented currently, but for now see notes in ps.c for more
details).

(3) New pstex driver.  This is not currently documented, but there is post
from Jo=E3o Cardoso on plplot_devel
(http://www.geocrawler.com/archives/3/10834/2001/4/50/5536095/) that gives
the recipe (ignore the configuration stuff and start with the ./x01c
command).  The idea is to emulate the pstex output of the xfig application
so that latex can be used to directly process the file output from the
PLplot pstex driver.

Tests Performed for this Release:

The testing this time was substantially deeper than before, but not as
broad. What I mean by "deeper" is that I did the usual extensive tests of
all examples both for the psc and png drivers as well as interactive testin=
g
using the Tk widget, the gnome driver, etc.  In addition, with the portrait
mode now available, yplot was fully available for the first time (watch for
that release announcement on this list) and was used to generate a large
variety of test examples.  What I mean by "not as broad" is our range of
test platforms was limited this time to just Debian potato, Redhat 6.1, and
SuSe 7.0.  However, previous releases were tested on a broader range of
platforms so we don't anticipate any special platform-dependent problems
with this release.

General Note:

This is probably going to be the last release in the 5.0.x series for
PLplot.  It is planned that the next release (5.1.0) will have an increased
minor number to mark the event of at least two important new features: a
whole new automake and libtool configuration scheme which has the potential
of much better cross-platform support and drivers which dynamically load as
required.  These two features have been developed on unstable CVS branches
and should be imported to CVS HEAD for stabilization work in the near
future.

Have fun with this latest stable release of PLplot!

Hello,

I just grabbed the plplot sources, and tried a build on my hpux10.20
c3600 machine. It builds ok. Also ps, pbm hardcopy stuff works ok. tek 
(xterm) works ok. x11 does not work. tcl/tk does not work.
Here is what I get:


Enter device number or keyword: 1
X protocol error: error=8 request=1 minor=0

X protocol error: error=3 request=2 minor=0
X protocol error: error=3 request=2 minor=0
X protocol error: error=3 request=12 minor=0

I have to hit ^C. 

For "tk"

I need one or the other since they provide colored lines. Is there a

Re: [Plplot-general] RE: Installation of plplot

[Bryan P. <pet...@ma...>]

Thang,

I have a colleague who has an older verion of PLplot (might be
4.99f) running on Windows 95 using Microsoft C and Compaq/Digital
Fortran.  He has not had the time or incentive to update the files to run
on version 5.0.3 yet.  I can make the files available that he modified
available if you would like them.  We haven't added them to the official
distribution because we really don't have the resources to provide any
support for them.  I have a copy of the 990122 snapshot that I think will
work with his fixes if you would like to try that or you can try making
the fixes work with version 5.0.3 (I think the only real changed needed is
to the fix the locations of the include files).  Let me know if you would
like a copy of the msdev files.

[Plplot-general] RE: Installation of plplot

[Geoffrey F. <fu...@ga...>]

Hello Thang,

I am not actively using PLplot on Windows at this time.So I am not
very able to respond personally.  I've taken the liberty of cross
posting this reply to plplot-general, the general discussion list for
PLplot.  Hopefully someone in the community will have some helpful
advice.

We do want to be able to support commonly used platforms with PLplot,
so if you or anyone else would like to update the support for msdev,
please feel free to contribute updated code or documentation.  Writing
to plplot-devel would be a good place to start.  

We do have active support on Windows/DJGPP at this time, but I do not
know how relevant that is for msdev.

If I ever do get around to looking into the WXX situation personally,
it would probably be in a cygwin context, at least initially.
However, there is no timeline for this, since I remain blissfully
engrossed in my Linux environment at this point in time.

With regard to the ancient version request, we don't have the
historical archives up at sourceforge right now, but it would be
possible to checkout any dated version of PLplot using anoncvs with
some appropriate date tag.  Does anyone out there know a date when the
msdev version was known to work?

[Plplot-general] Source and binary rpm's for RedHat 7.1 released for PLplot 5.0.3

[Alan W. I. <ir...@be...>]

Abed M. Hammoud has kindly created source and binary rpm's on his RH-7.1
system for PLplot 5.0.3.  These rpms can be downloaded from
http://sourceforge.net/project/showfiles.php?group_id=2915&release_id=35438/plplot-5.0.3-4.src.rpm
and
http://sourceforge.net/project/showfiles.php?group_id=2915&release_id=35438/plplot-5.0.3-4.i386.rpm.
(To access the RH 6.2 versions that have been available at sourceforge for
some time substitute plplot-5.0.3-1 for plplot-5.0.3-4 in the above names).

Unlike the RH 6.2 rpm's which are necessarily limited due to old versions of
Tcl and other packages on RH 6.2 which we do not support, the RH 7.1 rpm's
correspond (with two exceptions) to a full double-precision configuration of
PLplot 5.0.3.  Thus, along with virtually everything else you expect in
PLplot, the new rpm's include the Tcl/Tk, python, c++, and fortran front
ends; the new gnome (experimental) driver; the new png and jpeg drivers; and
the new documentation in a variety of forms. The exceptions to the full
configuration are the itcl part of Tcl/Tk front end and the octave front
end.

Our tests have included Abed using the plplot-test.sh script to create psc,
png, and jpeg files on his system corresponding to all the examples.  That
is a pretty comprehensive test that everything configured is built okay, but
since we are both relatively inexperienced at making rpm's please be careful
out there when using these rpm's.  In particular the dependencies may need
some work.

If you find any problem with these RH 7.1 rpm's, please let Abed
<abe...@ya...> know about it since he is taking full responsibilty
for these rpm's. I have consulted with Abed in the creation of these rpm's,
but I can only help with questions about these rpm's in a general way
because I have no access to RH 7.1 (yet).  I will continue to take full
responsibility for the RH 6.2 rpm's.

Yes.

Too bad.

It looks like that in AIX all symbols need to be resolved at link time, e=
ven=20
if the compiled file is to be dynamically loaded by another program that =
has=20
all symbols resolved.

Can you try to read the AIX "ld" man page and discover the command line=20
option that enables the creation of the output file even with unresolved=20
symbols?

A quick fix will be to add the octave libraries to the compile command, s=
uch=20
as:

 c++ -shared -o plplot_octave.oct plplot_octave.o -L. -lX11 -lnsl -lm=20
-L /usr/local/test/lib/octave -lcruft -loctinterp -loctave

The -L options must be suited to your system; not all three final librari=
es=20
are needed, or their order might be different.

Last chance:

Create the oregonator.cc file with the contents supplied bellow, compile =
and=20
run it. Does it works on your system?

$mkoctfile -v oregonator.cc
c++ -c -fPIC -I/usr/include -I/usr/include/octave-2.0.16 -mieee-fp -fno-r=
tti=20
-fno-exceptions -fno-implicit-templates -D_GNU_SOURCE oregonator.cc -o=20
oregonator.o
c++ -shared -o oregonator.oct oregonator.o

[Plplot-general] trouble compiling plplot with shared libs

[Gerd B. <bu...@pi...>]

Hi,

I tried to compile plplot using the attached configuration. In the
final linking step,

c++ -shared -o plplot_octave.oct plplot_octave.o -L. -lX11 -lnsl -lm -lplplotd

I get the following errors:

Any help?
