Graphics module not installing or acting weird

[sumanstats]

I am trying to use PDL(https://metacpan.org/pod/PDL) and for plotting the ndarrays, I need Graphics libraries. So I tried to install PDL::Graphics::PGPLOT

Looking at the error Gnuplot exists but yours doesn't support either the x11 or wxt terminal, I don't know what to do.

How to get over this error and use PDL with strawberry perl? Any help?

Hi, As regards the pdl2 shell, I'd recommend just using it and see if it works ok for you. I seemed to fare a little better than you:

pdl2 Unable to get Terminal Size. The Win32 GetConsoleScreenBufferInfo call didn't work.

You'll need the pgplot library in order to build PGPLOT and PDL::Graphics::PGPLOT. If you like, I can send you the pgplot library that I used when I was building those 2 perl modules.

Strawberry ships with the plplot library, so PDL::Graphics::PLplot-0.74 should be buildable. That module is currently broken for Windows - but the breakage is hopefully fixable.

Download https://cpan.metacpan.org/authors/id/D/DH/DHUNT/PDL-Graphics-PLplot-0.74.tar.gz, unpack it and cd to the top level directory ( PDL-Graphics-PLplot-0.74). Then run 'perl Makefile.PL'. I get the following braindead rubbish:

C:\sisyphusion\PDL-Graphics-PLplot-0.74>perl Makefile.PL PDL is installed

Checking PDL::Graphics::PLplot... Searching for libplplot.dll library. Searching for libplplotd.dll library. Cannot find plplot library (libplplotd.dll), skipping PDL::Graphics::PLplot

  Not building PDL::Graphics::PLplot

Cannot find plplot library (libplplotd.dll), skipping PDL::Graphics::PLplot Not building PDL::Graphics::PLplot Checking if your kit is complete... Looks good

So, the first thing to try is to fix the Makefile.PL so that libplplot.dll (which exists in c/bin) is located. At line 57 of the Makefile.PL, I inserted the location of libplplot.dll:

foreach my $libdir ( 'C:/_64/strawberry-5.32.1-PDL/c/bin', # location of libplplot.dll on my machine ...

I also set 2 environment variables:

set PLPLOT_LIBDIR=C:/_64/strawberry-5.32.1-PDL/c/lib set PLPLOT_INCDIR=C:/_64/strawberry-5.32.1-PDL/c/include/plplot

The 'perl Makefile.PL' step then succeeded. Next, I ran 'gmake test', but there was an undefined reference:

gmake test ... C:/_64/strawberry-5.32.1-PDL/c/bin/../lib/gcc/x86_64-w64-mingw32/8.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: PLplot.o:PLplot.c:(.text+0x91b59): undefined reference to `c_plshade1' collect2.exe: error: ld returned 1 exit status gmake: *** [Makefile:481: blib\arch\auto\PDL\Graphics\PLplot\PLplot.xs.dll] Error 1

I don't know why that is happening. It's late over here, and the rest will have to wait until tomorrow. Maybe you can make some more progress in the meantime.

Cheers, Rob

Seems that "c_plshade1" has been deprecated. See https://github.com/PDLPorters/pdl-graphics-plplot/issues/6

IIUC, the function would have been available if Strawberry had built the PLplot library with -DPL_DEPRECATED . But that wasn't done.

I have strawberry-perl-5.28.0.1-64bit-PDL.zip, and its PLplot library does provide "c_plshade1". So the simplest thing for you to do, is to replace your current c/bin/libplplot.dll and c/lib/lib/plplot.a with the same files from the 5.28.0 strawberry PDL distro. Also you need to replace the c/include/plplot directory with the same directory from the 5.28.0 strawberry PDL distro. (The PLplot installation that ships with the 5.30.0 strawberry PDL distro might also be ok .... I haven't tested that.)

Of course, you'll also need to do the things I outlined in my previous post

• ie fix the Makefile.PL and set the 2 environment variables.

That worked fine for me, despite some noisy tests (compiler warnings, and a couple of generated files that couldn't be unlinked):

All tests successful. Files=3, Tests=253, 51 wallclock secs ( 0.06 usr + 0.01 sys = 0.08 CPU) Result: PASS

[sumanstats]

Thank you for looking into the issue. I hope strawberry would look into these intricacies and make it easier for a beginner who want to start with scientific programming in perl.

Yes, it would be nice if they could re-build the PLplot library with -DPL_DEPRECATED and maybe, for the PDL distro, they could also set the PLPLOT_LIBDIR and PLPLOT_INCDIR environment variables in portableshell.bat.

But that won't help the Makefile.PL locate the plplot dll. That should be fixed by the PDL::Graphics::PLplot maintainer but, until that happens, the person wanting to build PDL::Graphics::PLplot is the one who is probably going to have to hack the Makefile.PL

Maybe, if you're lucky, the Strawberry developers will do that hacking and also then provide PDL::Graphics::PLplot in the distro ..... but I'm not sure how much trouble they want to (or ought to) go to.

It will be interesting to see what the Strawberry Perl releases of their perl-5.34.0 distros actually contain.

Cheers, Rob

Please try PDL-Graphics-PLplot-0.79.

This may have been fixed by https://github.com/PDLPorters/pdl-graphics-plplot/pull/16. You may see an issue with interactive plotting, but plotting to files should work.

[sisyphus]

A straight out cpan -i PDL::Graphics::PLplot failed to install Alien::PLplot, so I broke it up into a few steps:

> set ALIEN_INSTALL_TYPE=share
> cpan -i Alien::cmake3

Then I installed Alien::PLplot the ol' fashioned manual way. (I've no reason to doubt that cpan -i Alien::PLplot would have worked just as well)

Then I installed PDL-Graphics-PLplot-0.79 via the same manual method. (Again, I believe cpan -i PDL-Graphics-PLplot would also have worked.)

The 'gmake test' step produced some noise (see attached plplot_tests.txt) - though I think all of that noise is expected.

plplot_tests.txt

[zmughal]

Thank you for testing that @sisyphus! Yes, that noise is expected from the tests on Windows.

[shawnlaffan]

Testing PDL::Graphics::PLplot with the current 5.36.1 dev release results in test failures.

It looks like the system crashes on test 17 when it tries to call

$pl->shadeplot ($z, $nsteps, BOX => [-1, 1, -1, 1], PALETTE => 'RAINBOW')

Wrapping the code in an eval has no effect.

If I run plplot.t under gdb then all tests pass and the script completes normally. I'm not sure what to make of that.

perl -Mblib t\plplot.t
ok 1 - An object of class 'PDL::Graphics::PLplot' isa 'PDL::Graphics::PLplot'
ok 2 - Simple line plot
ok 3 - Simple line plot with LINEWIDTH specified
ok 4 - Symbol plot
ok 5 - Lines and symbols
ok 6 - Sample layer statistics plot
ok 7 - Setting pagesize
ok 8 - Line plot with gaps (plgapline)
ok 9 - Setting JUSTify = 1
ok 10 - Printing text inside and outside of plot window
ok 11 - Colored symbol plot with key
ok 12 - Colored symbol plot with key: reverse rainbow
ok 13 - Colored symbol plot with key, via low level interface
ok 14 - plgvpd call works correctly
ok 15 - plgvpw call works correctly
ok 16 - 3D color plot, low level interface

Edit - I set the PLPLOT env vars to the relevant share dir before running the build.

[shawnlaffan]

Setting set disable-randomization off in gdb replicates the crash (setting courtesy stackoverflow).

[shawnlaffan]

FWIW, the backtrace looks similar to the last parts of the one for OpenGL.

[shawnlaffan]

Also FWIW, there are similar test failures under linux with perl 5.37.x so this would not seem to be Strawberry Perl specific. http://matrix.cpantesters.org/?dist=PDL-Graphics-PLplot+0.83

This one, for example, also crashes on test 17: http://www.cpantesters.org/cpan/report/6c4cf676-cc37-11ed-95c7-b1478086ef20

[mohawk2]

Is this fixed by the vmem change?

[shawnlaffan]

Is this fixed by the vmem change?

No. This strawberry build includes the vmem change.

[mohawk2]

I'm a bit lost, because it's not at all clear what function it's crashing in (and the same is true of the OpenGL problem, though thanks for capturing the info onto an issue). Would it be possible to tell gdb to break in a plausible function, possibly the actual PLplot plsstrm (one of the first functions called by shadeplot, though might also be called by others), and seeing what bad data is causing the problem?

[shawnlaffan]

I'm sure it's possible but it's best done by someone familiar with the process.

If anyone wants to have a go then the relevant Strawberry perl version can be downloaded from https://github.com/StrawberryPerl/Perl-Dist-Strawberry/releases/tag/dev_5.36.1_20230528_gcc13

[shawnlaffan]

If it helps, the set of patches and other settings used for the build are below.

HAS_BUILTIN_EXPECT is disabled due to stability issues (#85). Would it be possible for HAS_BUILTIN_CHOOSE_EXPR to have similar issues?

https://github.com/StrawberryPerl/Perl-Dist-Strawberry/blob/da78325f3fdaa309589ae159d89776f8894ab29d/share/64bit-5.36.1.1.pp#L57-L86

[shawnlaffan]

Disabling HAS_BUILTIN_CHOOSE_EXPR and d_builtin_choose_expr makes no difference.
