Has more drivers and bindings at least. Also, transitioned to CMake. Autotools are still provided but are deprecated and a quick bump did not work, so, likely, adjusting ebuild to use CMake is necessary. I'll try to do this some time soon (btw, it has Ada bindings, thus CC ada@g.o), but anybody is surely wellcome to do this as well. George

Created attachment 147324 [details] zeroth order ebuild for plplot-5.9.0 Please note that this ebuild needs quite a bit more work. That said, it does compile for me with most useflags. Things that are currently non-functional include 1) octave bindings do not work for octave-3.* (need to look at included debian patches) 2) freetype stuff doesn't compile 3) ditto for wxWindows/wxGTK Please give it a spin and report additional problems. Patches to fix issues (such as the above) are of course also welcome. cheers, Markus
Damn, I'm one day too late! I had been sitting on my own plplot ebuild for version 5.8.0 (the version marked stable upstream) for a while, and I've been gradually getting more and more drivers and features working in it. I might as well just post it now in the hopes it will be useful to the other people working on 5.9.0. I've also tried to document what I've done, what works, and what doesn't, so excuse the long post. At least I now have a functional plplot-5.8.0 ebuild that compiles most drivers and works pretty well. Read on for gory details. It has the following USE flags: "X agg cxx fortran gnome ifc itcl itk octave pango pdf python qhull svg tetex tcl tk threads truetype java wxwindows" I had the following USE flags set when building: "X cxx fortran gnome java pango pdf python svg threads truetype wxwindows" The following list contains the drivers that I managed to build: < 1> xwin X-Window (Xlib) < 2> gcw Gnome Canvas Widget < 3> ps PostScript File (monochrome) < 4> psc PostScript File (color) < 5> xfig Fig file < 6> hp7470 HP 7470 Plotter File (HPGL Cartridge, Small Plotter) < 7> hp7580 HP 7580 Plotter File (Large Plotter) < 8> lj_hpgl HP Laserjet III, HPGL emulation mode < 9> pbm PDB (PPM) Driver <10> png PNG file <11> jpeg JPEG file <12> null Null device <13> mem User-supplied memory device <14> gif GIF file <15> wxwidgets wxWidgets DC <16> psttf PostScript File (monochrome) <17> psttfc PostScript File (color) <18> svg Scalable Vector Graphics (SVG 1.1) <19> xcairo Cairo X Windows Driver <20> pdfcairo Cairo PDF Driver <21> pscairo Cairo PS Driver <22> pngcairo Cairo PNG Driver Most of my testing has been through the Perl interface (PDL::Graphics::PLplot), but I have built the example programs for C, C++, Java, Fortran 77/95 and Python installed in /usr/share/plplot5.8.0/examples by the ebuild, and these work. The C++ bindings also allow some limited testing of the wxwidgets bindings, and these also seem to work. The plplot canvas widget is also built and works. The gcw driver segfaults for me when trying to save a hard-copy, but viewing the plots works fine. Tcl/Tk drivers have not been tested, nor the octave driver. Also not tested: using the agg and qhull libraries. These were next on my plplot agenda. Note: more thorough testing by knowledgeable people needed! Particularly people who would use plplot through langauges other than Perl! Maybe add testing functionality to the ebuild? So most, if not all of the dependencies were taken from the ebuild for the previous version, so the list may need to be checked and updated where appropriate. I've tried to do this from reading various READMEs located in the source and from the output of cmake and my compilation attempts, but it should most definitely be checked. Indeed, I think some dependencies are sub-dependencies of others while others are conditional dependencies - basically it appears to be quite a mess so guidance would be greatly appreciated. I've got an ebuild for the LASi library, which allows one to build drivers that render postscript with truetype fonts. This also requires pango. Default postscript drivers are built regardless (and cairo ps/pdf drivers are built if you have cairo installed). I will attach the LASi ebuild to a separate bug and link to it from here. I had to write a dirty dirty patch to get plplot to find, build and link against freetype. Most of the inspiration and success comes from a random Google search that turned up a FindFreeType.cmake module file which is part of the FlowVR project, which instead of searching for freetype header files just used the output of the command freetype-config. The other parts of the patch are my dirty hacks being a complete novice with cmake to glue it all back together. I'm unsure about the handling of various supported fortran compilers. Not being a fortran user this part of the ebuild could do with some love from a person knowledgeable in that. So in summary: plplot 5.8.0 works, compiles and some core bindings work. Hopefully it will work for other people. Ebuild needs lots of work in sorting dependencies, consolidating patches and driver testing. Use at your own risk ;) Happy plotting, Joshua Rich
Created attachment 147365 [details] ebuild for version 5.8.0 (upstream stable) Ebuild for version 5.8.0, hopefully will be of use for getting 5.9.0 working.
Created attachment 147366 [details, diff] patch to find and set-up correct compiling/linking with freetype on Gentoo
See bug #214846 for the ebuild for the LASi library required for the ebuild of plplot 5.8.0 attached to this bug.
Hi Joshua, Thanks a lot and it looks like our two attempts look pretty similar overall ;) I'll merge the best of both into a new revision for 5.9.0 and we can then go from there. Do you think there's any point in keeping the png/jpeg useflags? AFAICT there's no switch any more to turn these on or off. cheers, Markus

The png/jpeg USE flags were copied over from the older plplot ebuild. You are right though, there is no switches to enable/disable this support. Maybe they can be merged to the 'gd' USE flag, so that people who don't want jpeg/png output can still disable this support? See the FindGD.cmake and gd.cmake files in the cmake/modules directory of the source, it looks like the configure step will do the right thing if gd isn't found. I'll leave it up to you though. Let me know if you need some informal testing done. I can at least test the Perl bindings, as well as compile and run the example programs as before. Another thing, I think in order to get the wxwidgets bindings/driver to build I had to run the eselect module for wxwidgets. I have wxGTK 2.6.4.0-r3 and 2.8.7.1-r1 installed, and selected gtk2-unicode-release-2.8 through the eselect module. I don't know whether this is required, but I think the compilation failed unless I did this. Thanks and regards, Joshua
Folks, I was also working on some fixes after the first post from Markus. I tried to update them and put all the changes in the science overlay. I also tried to regroup some use flags. I'm not sure of the utility of the X one when there are so many of them pulling the X libraries. I tried the ebuild with all the use flags turned off, and all turned on except ada (200 packages to pull...). There are so many use flags I tried to choose some decent default ones. Still some work to do: * include some debian patches? * ada tests * freetype: I did not need the patch so it might be flaky * doc generation to check * not sure if we can add svgalib I'm only using this package for gdl, so I'm not a good tester. Feel free to modify the package in the overlay and report here.

I compiled all the demos (for all the languages I compiled: Java, Fortran 77/95, Perl, C, C++) and randomly ran a few examples from a few languages and outputting to random drivers, all seems to work really well! I did have a couple of issues: - I get a warning in the cmake configure output that it can't find the freetype fonts, but freetype postscript output is available (and works) in the compiled and installed package. So I think this is a false warning. You don't need the patch I made for 5.8.0 to get freetype support. - The gcw driver still segfaults when trying to save a hardcopy of a plot (when running one of the compiled examples). Can anyone confirm this or is it just me? That is about it though! Thanks and regards, Joshua
It seems that these ebuilds depends on numeric when using python flag. As per bug #181653 numeric is deprecated and it should be removed from the tree sometime. dev-python/numpy is its subsitute, and it should be used instead of numeric. PlPlot supports numpy, and is prefered over numeric.
plplot-5.9.0.ebuild is missing the 'truetype' USE flag in IUSE. Only discovered this when running emerge --pretend --depclean and the lasi and freefont packages were to be removed. Cheers, Joshua
Hi, thanks for the new ebuild. I think, the built_with_use calls in pkg_setup should be conditional on use flags. The package doesn't install for me since I haven't got wxGTK installed (the use flag wxwindows is not set). pkg_setup fails when it tries to call built_with_use on wxGTK. Cheers, Jochen
plplot-5.9.0 now in main tree with many fixes. Please test it. If any bug or suggestion, open a new bug. Thanks all for your work
