plplot is a library that can output plots in several different formats.  I 
think it's nice to have.

You could try writing an ebuild for this until we get through our bug list
to this one :-)

Ebuild for plplot

Here is a tbz2 file with and ebuild for plplot.  I untared it in
/usr/portage/dev-libs and it appears to work correctly.

improved ebuild

This added USE flags doc and debug.
Also fixes segfaults in the package.
Still needs the patch from the other attachment.

Could you attach the patch as a text/plain file, so it's viewable from the
web?

plplot-5.3.0.ebuild - New ebuild

There is a new version of plplot (5.3.0). Here is a new ebuild, based on
Tyler's. Here is what I changed:

- The patch has been included upstream, so it is no longer needed.
- Corrected the way documentation is handled (--with-prebuilddoc assumes
documentation is already built. This is not the case.) 
- Added missing dependencies (pkgconfig, man, perl, opensp, jre, jadetex,
octave, libgd, truetype, tk, itcl, gnome-libs). These are not mandatory, but
some bindings and drivers depend on them.
- Added USE flags to control what language bindings and device drivers are
built (gd-external, gnome, java, jpeg, png, tetex, truetype, X, itcl and
octave). These flags are also used to determine dependencies.
- Made fortran support optional and added an option to use Intel's Fortran
Compiler (ifc) instead of the GNU Fortran Compiler (f77).
- Better compliance with Gentoo FSH (docs, shared files and java libs). I also
changed the octave script which loads plplot, to reflect the changes in the
files locations.

I still have two problems with the package:

- I can't get the documentation to build. The configure script doesn't locate
my catalog files. The html documentation is available (and installed), but
there is no pdf, dvi or info files.
- I can't get the configure script to locate libqhull, so I disabled it.

- Assigns to the sci herd
- Provides long description

I believe there's a configuration problem with the 5.3.0 ebuild in that it
assumes files are in /use/share/plplot5.3.0/ when they're in
/usr/share/plplot/. 

Details:

I can compile the example programs in /usr/share/plplot/examples/c/ but they
crash on running: e.g.

$ ./x01c

*** PLPLOT ERROR ***
Unable to open or allocate memory for font file
Program aborted

The choice of device doesn't matter. Using strace I found that it was looking
for the font file in /usr/share/plplot5.3.0/ whereas I only have
/usr/share/plplot/ [strace output below]. I hacked this by adding in a soft
link as I don't know enough about the gentoo layout to know what to hack in the
actual ebuild.

Diff of plplot-5.3.0.ebuild

This is a diff of the previous ebuild. It corrects the problem described on 
comment #8. I have successfully compiled and run the new ebuild on amd64 arch
with GCC 3.4, and compiled the C++ exmamples in /usr/share/plplot/examples/c++.

They now run correctly and I have tested them using the xwin and png drivers.

 eerror "GNU fortran 77 compiler not found on the system."
        eerror "Please add f77 to your USE flags and reemerge gcc."

I think this error message should now read "Please add fortran to your USE flags"

patch to fix octave in plplot 5.3.1

This patch applies the 5.3.0 patched with Comment #9.  Changes:
1)  Fix octave dependency from the app-sci -> sci-mathematics move
2)  Fix the paths used for plplot's .m files
3)  Change warning in Comment #10.

I will attach my new ebuild with this patch applied.

plplot-5.3.1-r1.ebuild

I am still working on this - I had already added doc installation, fixed the
fortran USE flag and had changed the octave dependency. I tried your patch for
the octave path and it does not work on my amd64 system,

I will dig a little deeper and see if I can get to the bottom of that error
later when I have some time. Once I have it working I will put it into the tree
under sci-libs. Diffs are preferred to ebuilds as it is easier to see what you
have changed.

My patched only changed src_install.  It also shouldn't be archecture
dependent; it only moves a file and runs sed.  Are you sure that error is
caused by my changes?

Re: diffs: I also attached a patch (see Comment #11).

I didn't mean to imply that your changes broke the octave support, just that I
would not be adding it until I had sorted out all remaining issues. I found a
patch on Debian's bugzilla that seems to fix this issue, just testing it out
now.

I should be able to get this added and in testing for x86 and amd64 soon - just
a little more testing is required.

I have added plplot to the tree. Please test it out and let me know of any
issues. I think I have addressed most of them, but it is quite a complex
library so I could have missed something. Thanks for all the contributions
made.
