[Plplot-general] Static-linked, stand-alone executables?

[ooOoo <jg3...@ya...>]

Is it possible to build statically-linked, stand-alone
executable files with plplot?

When I link with the -static option, I get many
"undefined references" (see output below).  This
result was with the 5.2.1 version of plplot, running
under RedHat 9, with f77.

Thinking that I may not have built the plplot
libraries to enable static linking, I began to install
the 5.3.0 version.  After getting through make, I saw
nothing listed after "Available device drivers/static"
(see output below).

Am I doing something incorrect, or is it simply not
possible to make stand-alone executables?
---- errors generated when trying to build a static
executable ----------

plplot-5.2.1

This is the link command I used:

f77 -static -o itcsim2   itcsim2.o hybrd1.o deriv1.o
gaussj.o sort2.o lspoly.o itc2.o timedate.o -L
/usr/local/lib -lplplotf77 -I/usr/local/include/plplot
 -L/usr/X11R6/lib -lX11 -lieee -lm

... which gave these errors:

/usr/local/lib/libplplotf77.a(scstubs.o)(.text+0xd):

... followed by many more lines like the ones above

   (After editing the configure file to change the

project. It is only available for Mac OS X 10.3, and the 'unstable' 
tree of fink needs to be enabled. Please refer to fink documentation 
how to do this.

I would appreciate any feedback on installing and usage (positive or 
negative :-).


thanks,

The quick answer is tutor.c is unmaintained at the moment.  There have been
PLplot API changes, and tutor.c may well be a victim of that.  Try the
x??c.c examples (which are well-maintained) instead to start.

If you decide to dig deeper into tutor.c and find what is wrong with it (by
comparing with the x??c.c examples or looking at our detailed documentation
at http://plplot.sourceforge.net/docbook-manual/), then please send me a
patch, and I will make the appropriate change in our code base.

[Plplot-general] Problem with examples in c in tutor.c

[Javier G. L. <j_...@ab...>]

I can compiled tutor.c and i have created the file that needs it in the right 
way. However, i can`t see points united by lines as i think it must be as 
follows in the code:

for (i = 0; i < M; i++) {
        plpoin(N, x, y[i], i + OFFSET);
        plline(N, x, y[i]);
    }

Should i see points united by lines? Why i dont see then?

Just found this message in my inbox - probably
very late due to problems at SF.

Copy the font files into the directory containing
the example programs and try again
(you can find them in the data directory)

There is a more elegant solution, but I do not know
by heart - an environment variable like PLPLOT_DIR (?)

[Plplot-general] Announcement of PLplot-5.3.0

[Rafael L. <rla...@us...>]

[N.B.: this is the text version of the announcement in http://plplot.sf.net]


Announcement of PLplot-5.3.0
     _________________________________________________________________

Release Notes

   The [1]PLplot development team is proud to announce the release of
   version [2]5.3.0 of the [3]PLplot scientific plotting library. This
   version of PLplot comes out nine months after the latest release
   (5.2.1) and represents a considerable amount of development work, as
   documented in the [4]ChangeLog of CVS activity. The main focus of this
   release is the strengthening of "niche occupation" by PLplot. Indeed,
   two of the traditional core language bindings (C++ and Fortran 77) are
   highly improved, and the configuration/build system became more
   robust, allowing successful installations in platforms like MacOS X
   and Cygwin.

Changes

API

     * With this release, the ABI (Application Binary Interface) backward
       compatibility of the PLplot library has been broken, because the
       libraries libnn and libcsa were renamed to libcsironn and
       libcsirocsa, respectively. For this reason, the soversion number
       had to change. In Linux, for instance, the libraries are called
       now libplplot*.so.9.0.0.
     * plsabort: New function. Similar to plsexit, should be used to set
       a handler for the plabort function.
     * plot3d: Plot a contour only if the number of points in the contour
       is greater than zero.
     * plshade: Fixed corner case when argument pltr == NULL and
       contouring is wanted.
     * plgriddata: Arguments have type PLINT now, consistent with the
       rest of the API.
     * plline: Fill clipping improved.

Language Bindings

     * The C++ API has been totally rewritten, with 13 API additions,
       most notably the command-line parsing functions. The interface is
       much more modern now and the demos were revamped. Several backward
       incompatibilities have been introduced, such that the libplplotcxx
       has a separate soversion number now, independent of that for the C
       PLplot library.
     * The API for Fortran 77 was completed and should be more portable.
       It includes the functions for parsing command line options, as
       well as plstripc-, plshade- plmesh-, and plsurf-related API
       functions. The examples were rewritten and mimic the C examples
       closely.
     * The Java stubs are collected into a loadable module instead of in
       a library as before. Setting LD_LIBRARY_PATH is not required
       anymore. Also, there is no need for using CLASSPATH. Since the
       Java interface is now mature, its building is enabled by default.
     * PLplot support was included in the latest version of [5]PDL (the
       Perl Data Language). Porting of the C PLplot demos to Perl has
       started and the first file is included in this release
       (examples/perl/x01.pl). The PDL bindings are likely to evolve a
       lot in the near future, and the C demos will be ported
       progressively.
     * Many Octave demos are improved now, in particular those featuring
       mouse interactivity. Although the bindings are still compatible
       with the 2.0 series of Octave, compatibility at the script level
       is only guaranteed for the 2.1 series. However, there are some
       issues with the latest version of Octave (2.1.53) and, for this
       reason, Octave bindings build is disabled by default in configure.

Drivers

     * The drivers for Windows (DOS/djgpp, Win32/msdev, and win-tk) have
       been updated and should work in this release.
     * The line width setting in the ps/psc driver is fixed and the
       results are visually equivalent to those obtained with the other
       drivers.
     * In the xwin driver, a window resizing bug is fixed. This bug
       appeared when several windows were used in a pthreaded
       application. Also, the xwin driver uses now by default pthreads as
       well as "default visual". To disable them, the user has to use
       "-drvopt usepth=0" and "-drvopt defvis=0".

Config/Build/Install

     * The Autotools-based PLplot configuration became much more robust.
       The autoconf/automake/libtool constructs have been modernized and
       several combinations of configuration options work better in this
       release.
     * Use of "make prefix=/some/path install" for setting the
       installation prefix works now.
     * Compliance with the [6]FHS (Filesystem Hierarchy Standard) is
       being pursued. The architecture independent data files are now
       installed in ${prefix}/share/plplot<version>.
     * The previous support for a local defaults file for configure has
       been removed in favor of the built-in CONFIG_SITE support. The
       reconfig script is made permanent and not automatically generated
       as before.
     * Checks for C compiler NaN awareness is improved (this is necessary
       for compiling the libcsironn/csa libraries).
     * The Python and Swig configuration code is more robust now.
     * The [7]pkg-config support has undergone a total rewrite and should
       be much more portable with this release. It is activated with
       option --with-pkg-config to configure. The plplot-config script is
       still kept as an alternative to the pkg-config support. See the
       installed example/*/Makefile for examples of use.
     * When developing the PLplot library itself, developers do not need
       to install the whole package in order to text/evaluate the
       changes. This is implemented through the new core function
       plInBuildTree, and the new configuration variable BUILD_DIR.

Library core

     * Memory management fixes: almost all of the memory leaks revealed
       by [8]valgrind are gone. There are still some problems under
       investigation and their fixes will be integrated in the next
       release.
     * The libraries libcsironn and libcsirocsa were updated to versions
       1.38 and 0.22, respectively.
     * Almost all compilation warnings messages disappeared, even when
       compiling with gcc -Wall.
     * plOpenFile: sane use of stderr and stdout. This function respects
       the option -debug now.
     * Re-enabled the setting of the tcl_cmd internal option (only
       affects plrender -dev tk).

Documentation

     * The PLplot Documentation in DocBook format is released now under
       Free Software terms, with a license similar similar to the
       [9]FreeBSD Documentation License.
     * The HTML form of the documentation uses [10]CSS (Cascade Style
       Sheets) now.

Tests

     * The test suite test/plplot-test.sh fully works for all front-ends.

Acknowledgments

   The following PLplot core developers actively participated in this
   release: Joao Cardoso, Vincent Darley, Alan W. Irwin, Rafael
   Laboissiere, Maurice LeBrun, Arjen Markus, Andrew Roach, and Andrew
   Ross.

   Several people participated as testers and/or helped to port PLplot to
   different systems and architectures: Koen van der Drift, Ullal Devappa
   Kini, Rob Managan, Per Persson, Michel Peyrard, Valerij Pipin, Olof
   Svensson, and Brian D. Wright. Many others have participated to
   discussions in the plplot-devel and plplot-general mailings lists.

Is it the same that was already available on Sunday - or did you upload 
a new one with those last bug fixes?  In the former case, no problems 
on Mac OS X. If the latter, I need to redownload it and try it out 
later.

Since on Octave 2.1.53 glob returns a cell array instead of a padded char
array, call char() on the result of glob(), such that toggle_plplot_use will
work on both Octave 2.1.50 and 2.1.53.

[ RL for AWI: ]

The include directories aren't specified quite correctly in
bindings/python/Makefile.am.

AM_CPPFLAGS = $(INCLTDL) -I/$(PYTHON_INC_DIR) -I/$(PYTHON_NUM_DIR) $(X_CFLAGS)

should be replaced by

AM_CPPFLAGS = $(INCLTDL) -I$(PYTHON_INC_DIR) -I$(PYTHON_NUM_DIR) $(X_CFLAGS)

The first way puts a double slash in the result (since both PYTHON_INC_DIR
and PYTHON_NUM_DIR already have a leading slash). This double slash confuses
the Cygwin compiler and shouldn't be there anyway.

Add #ifndef ENABLE_DYNDRIVERS ... #endif about the lines in
plD_dispatch_init_XXXXX which assign pdt->pl_MenuStr and pdt->pl_DevName. If
this is a dynamic driver then we have already assigned these strings in
plcore.c using the database. We absolutely don't want to use a static string
in the dynamic driver to initialise it with since that string will disappear
once the driver is unloaded and we are left with no valid driver name or
menu item. Oh and overwriting the string will also leak the previously
allocated memory for the names.

Thanks, Valery, for that ALT Linux report.  We discovered integer typing of
iargc is the correct thing to do for other fortran compilers a few days ago,
but it is nice to have it confirmed for the pgi fortran compiler as well.
That fix and a number of other fixes we have accumulated should be be in the
second release candidate which should be ocming out shortly.  Watch this space
for the announcement.

I buit the binaries on ALT. Everythings went fine, exept fortran part.
On my mashine I have the trial version pgi compiler (pgf77,pgf90). The 
building stopped at compiling configurable.f (variable iargc is non 
declared). It is actually a function with void arguments.
I guess it shoud be declared as integer. Everything has gone well after

[Plplot-general] Welcome to two new members of the PLplot core developer team

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

On behalf of the PLplot core team I recently invited Arjen Markus and
Andrew Ross to join us, and I am quite pleased to announce that they have
both accepted our invitation.  In practical terms this means they will have
direct cvs write access to the PLplot code (rather than submitting patches
as before), and instant cvs read access.  There are intangible benefits as
well such as having more of a say in the direction PLplot will take in the
future.

To introduce the new core team members a little, Arjen is already in charge
of the sys/win32/msdev port of PLplot and also has substantial experience on
the Unix side of things as well.  His principal languages are C, fortran,
and Tcl; and he has recently helped out by providing standard fortran
examples to test our refurbished fortran interface. Andrew has recently
completely refurbished our C++ interface to PLplot, programmed the standard
examples in C++ to help test that interface, and also figured out some
long-standing bugs we had in the memory management of our core C code.

On behalf of the PLplot core team, welcome to Arjen and Andrew!  I am sure
they will both help our team achieve an ever brighter future for PLplot.

Alan

I have just tested the whole sequence of building the static and
dynamic libraries for the Win32 driver. Everything went smoothly,
with one minor exception:

The current makefile DExamples.mak in sys/win32/msdev/DExamples 
fails if the directory that will hold the results of the compilation
and linking does not exist yet.

It would be a matter of adding an extra command to that file per
example. 

If we think it is important enough to do that, then let me know. 
Otherwise I am satisfied with the current tarball.

Regards,

Arjen

On an alpha OSF1-4.0, with gcc-3.0.3, it configured/run almost OK.

Some problems:
isinf/isnan not detected during configure
pthreads  not detected during configure

configure:28152: gcc -o conftest -g -O2 -mieee   conftest.c  >&5
/bin/ld:
Unresolved:
isnan
collect2: ld returned 1 exit status

Compiling the test program with -lm solves the problem

examples/c++/x01 compilation fails:
    x01.cc:278: `usleep' undeclared (first use this function)
this was already reported and a solution searched, but none appeared

examples/x20 fails (in the build dir, didn't tried install):
   No such file - aborting
as lena.pgm was (of course) not found

examples/x18f the 5 and following pages aren't equal to the 
corresponding c examples, only a circle is ploted at the base xy plane

The installed Octave is very old and pluggins are not compilable -- this 
is not PLplot fault.

Configuring with the native fortran compiler fails at bindings/f77

f90: Error: configurable.f, line 35: This name does not have a type, and 
must have an explicit type.   [IARGC]
      numargs = iargc()
----------------^

The native fortran compiler was working in the previous release, so this 
is a step-back.

Commit from rlaboiss on branch v5_3_0 (2004-01-19 21:30 CET)
-------------------------------------

Break a long AC_MSG_WARN message into two lines, as per the recommended
practice. This is 80-columns-xterm friendly.

-------------------------------------

[ Forcing cvs commit to get the correct log message, screwed up in the
  previous commit: ]

When PLplot is configured with disable_shared, dyndrivers must also be
disabled. However, this test was done too late in configure.ac, after the
libltdl checks were done conditionally on the value of enable_dyndrivers.
This was causing needless checks and configuration of libltdl.

Since this check is done now before AC_PROG_LIBTOOL, where enable_shared is
usually initialized, an explicit initialization of enable_shared (=yes)  was
needed at the beginning of configure.ac.

Commit from rlaboiss on branch v5_3_0 (2004-01-19 21:09 CET)
-------------------------------------

This is a most cosmetic change, just to get the $(libplplot) variable added
to get_drv_info_LDADD instead of redefining it.

  plplot  drivers/Makefile.am  1.36.2.2


Commit from rlaboiss on branch v5_3_0 (2004-01-19 21:02 CET)
-------------------------------------

Parse the name of the library correctly when processing a *.la entry.  Wrong
results were occurring when the file name containing "lib"twice, as in
libglib.la.

  plplot  scripts/get-dependency-libs.sh  1.4.2.1


Commit from rlaboiss on branch v5_3_0 (2004-01-19 21:00 CET)
-------------------------------------

Include $(LIBLTDL) in libplplot@LIB_TAG@_la_LIBADD conditionally on the
Automake conditional enable_dyndrivers.  This fixes the problem of libltdl
being looked for when compiling libplplot under configure --disable-shared.

Documentation of the changes to the WIN32 driver
dd. 16 january 2004, by A. Markus

Note 1:
The files in this tree are expressly in Windows/DOS format
The reason is that we are not sure that UNIX/Linux format
would be acceptable to all compilers.

Note 2:
Since the changes are legion, I have documented them in detail.

win32/msdev/README.TXT
Added my name to the file

win32/msdev/makefile
Small corrections regarding the creation of the tmp directory
and copying all files to it.

win32/msdev/DExamples/DExamples.mak
Default target now x01d (release).
Added the flag __PLDLL_H__ - this must be defined, if the DLL
is to be used (see README file).
Path to the source files and the extension changed.

win32/msdev/plpdll/plpdll.mak
Added the flag "BUILD_DIR" to the compile step.
Relative path to the tmp directory.
plimage.c added to the makefile
Changed the extensions of some source files (from .cpp to .c)

win32/msdev/plplib/plplib.mak
Added the flag "BUILD_DIR" to the compile step.

win32/msdev/src/win3.cpp
Added a function w32_tmpfile() to solve the problem of
opening temporary files on network disk (the main directory
is often read-only and the version of tmpfile() that comes
with Windows, ignores the environment variables but simply
opens in the directory "\").
Replaced the export keyword by __declspec(dllexport)
(this seems to be the recommended way).

win32/msdev/src/plplotd.def
Added the routines plGetCursor, plParseOpts and plMergeOpts.

win32/msdev/src/plplot.rc
Corrected the path to the include files.

win32/msdev/src/plstub.cpp
Added stubs for the routines plGetCursor, plParseOpts and plMergeOpts.
Corrected call to plpoly3()
Corrected stubs for plshade() and plshade1() (prototypes for the
function arguments caused trouble)

win32/msdev/src/plplot.h
Updated the plplot.h file from a previous version.
Added the flag __PLDLL_H__ to select between three situations:
- Compiling the generic sources and Windows applications using the
  static library (neither __PLSTUBS_H__ or __PLDLL_H__ defined):
  Requires that the names c_plinit() and the like be untouched
  Define a macro plinit for user-code on non-Windows systems
- Compiling the Windows stubs (only __PLSTUBS_H__ defined):
  Requires that the names c_plinit() and the like be untouched
  Do _not_ define macros like plinit, as there are actual functions
  by these names. They are undefined at the end
- Compiling Windows applications that use DLL (only __PLDLL_H__ defined):
  Requires that the names c_plinit() and the like be turned to
  WINAPI plinit().
Added the macro API to the prototypes.

-------------------------------------

Add libplplot.la, as well as libcsirocsa.la (conditionally on with_csa) and
libcsironn.la (conditionally on with_qhull) to get_drv_info_LDADD such that
when get-drv-info is run to generate the *.rc files on MacOS X, there will
be a chance that lt_dlopenext will work without needing to set
DYLD_LIBRARY_PATH.

-------------------------------------

Changed the less robust @prefix@/@DATA_DIR@/examples/octave// to ./octave//
in octavedir.  plplot-test.sh works now from everywhere the examples
directory is installed.

This change is done in a relative hush, to make Alan happy and also before I
tag everything v5_3_0_rc1.  Everyday there is a new cool patch to apply...
Sigh...

Please, notice that this is committed only to the v5_3_0 branch.

Changed copyright holder (JC) and licensing conditions (LGPL -> GPL)

  plplot  bindings/octave/plplot_octave.h.in  1.2.2.1


Commit from rlaboiss (2004-01-17 17:41 CET)
--------------------

This jumbo cvs commit is the result of a herculean task to update the
copyright notices of most of the source files of PLplot.

I hope that I did not introduce any serious breakage.  This seems plausible,
because I did changes only at the beginning of the files and only in
commented lines.  However, I used a semi-automatic procedure for doing that
and some bugs may have slipped into the files.  The sources still build okay
(at least the Debian packages) and I can install the libraries, and compile
and run some C examples.  That is not enough, so PLEASE TEST!

This is what I did in more detail:

1) From the CVS ChangeLog, I considered all the files that changed since the
   last release (5.2.1).  I then added the line:

       Copyright (C) 2004  Joe C. V. S. Committer

   where the name of the developper who did the CVS commit is included.

2) Notice that the year in the line above should read 2004, even if the
   changes were done last year, since Copyright years refer to when the
   software is released.

3) For the same reason, I did not bother adding missing Copyright entries
   for previous authors of each file.  One copyright holder is enough for
   our purposes.

4) I also reformatted and reworded the License Conditions text.  This
   included changing things like "This file is free software" to "PLplot is
   free sofware" and so on.

5) Finally, some files were lacking License notices, especially the src/*.c.
   I added them and put in the Copyright holder line the name of the
   developer who did the last cvs commit for the file.

If you wish to know where your name appears, you can run from the
$(top_builddir):

    grep -ri "copyright.*2004".

Commit from airwin (2004-01-16 18:24 CET)
------------------

Rafael's script-based method of getting and using libtool information to
solve mkoctfile linking issues and a more careful approach to overcoming the
run library path issues of mkoctfile has proved successful not only on Linux
but also cross-platform. Therefore, abandon the pure libtool-based approach
to build the octave interface.

Note, we use the pure libtool-based approach to build every other interface,
and building the octave interface worked fine with the pure libtool approach
in the Linux case, but there was one cross-platform showstopper (couldn't
get the -shrext libtool option to work in the documented manner to set the
shared object suffix to .oct as demanded by octave) that I hadn't solved yet
when Rafael beat me to a solution using a special script-based method.

Start here, if future developers want to use the pure libtool approach for
building the octave interface.

Change script to simply mimic stdin except for case of -framework option
used by MacOS X.  In that case escape options by appropriate -Wl, commands
to pass on the -framework options to the linker via libtool.

Note this change is simply to get the script right for historical purposes
since it will soon be removed to CVS attic.

[Plplot-general] First release candidate (rc1) for PLplot 5.3.0 available

[Rafael L. <rla...@us...>]

The first release candidate tarball for the forthcoming 5.3.0 release of
PLplot is available at:

    http://people.debian.org/~rafael/plplot.html

and also as a File Release at SourceForge.

The tarball name is plplot-5.2.1.rc1.5.3.0.tar.gz.  The main user-visible
changes since the last cvs test tarball (5.2.1.cvs.20040115) regard
improvements in the configuration support for MacOS X.  We hope that all the
remaining issues on MacOS X are addressed in this tarball.

As usual, Debian packages for unstable (a.k.a. sid) have been uploaded.

Please test & report.

Actually, it would be a bit better to use plgpls() to get the stream pointer.
That way it would still work should you ever go with multiple streams, or if
we should ever make plsc unavailable to the outside world.  While plgpls() is
not part of the "common" API, it is still part of the standard "C" API AFAIAC.

If using the xwin driver, you can use the "-drvopt nobuffered" cmd line driver

I did the usual installed example non-interactive test I recommend for all
testers for their various platforms (note if /yourprefix is a directory area
that belongs to you, this entire test sequence can be done as an ordinary
user without requiring root access):

./configure -prefix=/yourprefix
make
make install
cd tmp
cp -a /yourprefix/share/plplot5.2.1.cvs.20040115/examples/ .
cd examples
export PATH='/yourprefix/bin:'$PATH
make
./plplot-test.sh

generated 89 postscript files without any problems, and they were identical
to the same 89 postscript files I did on January 4th.

==> no obvious problems on my Debian stable system.

I ran into a similar problem - and used the same solution. This had to 
do with PLplot being a library inside a larger application.

You might want to look at the Tcl/Tk binding: with Tcl/Tk you can easily
create user-interfaces and PLplot can serve to produce your graphical
display.

If you choose another solution, you will probably run into the problems
I referred to - I still have to commit them to the PLplot development
team - as they arose in this larger program, because it handles the
user-interface (and all window events) and uses PLplot as a graphics
library.
