There are several new versions of GRASS, the latest stable release being 6.2.3, but also several release candidates for 6.3.0. I'd like to see an ebuild at least for the first, preferably for the latter as well. I tried to build the current grass 6.2.1-r1 from portage, but couldn't because the ebuild complains about tcl/tk built with USE=threads, which I'm not willing to sacrifice. So I investigated the matter. Seems like that part of the ebuild originated in the grass-6.1.0.ebuild from October 2006 by nerdboy and was carried along ever since. I'm not sure how this relates to the following message from the upstream ChangeLog: 2006-03-16 23:41 cedric * visualization/nviz/src/: draw.c, exag.c, lights.c, map_obj.c, position.c, togl_flythrough.c, volume.c: NVIZ runs with TCL 8.4 Threaded: Memory allocated with Tcl_Alloc, such as the result of Tcl_Merge should be freed using TCL_DYNAMIC. To me that sounds like threaded tcl should be supported. The corresponding changes http://trac.osgeo.org/grass/changeset/19285 were already included in the 6.1.0 release. Any suggestions where the information about this incompatibility came from and whether it is still a problem? I'll try adapting the grass-6.2.1.ebuild to 6.2.3 and see if I can get it to run. But as I have never before worked with GRASS, I might be ill suited to evaluate whether the result works as expected.
Created attachment 149880 [details, diff] grass-6.2.3-html-nonviz.patch Derived from grass-6.2.1-html-nonviz.patch, this patch applies more easily, as it contains no context around the lines to be removed. An alternative would be to grep for all lines not containing nviz. An updated patch requires less modifications to the ebuild, though.
Created attachment 149882 [details, diff] grass-6.2.3-html-nviz-fix.patch Derived from grass-6.2.1-html-nviz-fix.patch, this patch applies more easily, as the context should stay unchanged for longer than that of the previous patch did. Also the patch is simpler and less in style with the rest of that script.
Created attachment 149885 [details] 6.2.3 ebuild take 1 Changes so far: * moved checks from src_unpack to pkg_setup * disabled checks for non-threaded tcl/tk * disables some patches and sed scripts that seem unneccessary * disabled elibtoolize as it seems to work without * moved patch application from src_compile to src_unpack * using shipped start script instead of ebuild-generated one So far for today, I'll continue when I find time again, in the meantime this should be a good starting point, as it does compile and install here. After installation I hit http://intevation.de/rt/webrt?serial_num=5328 and decided I'll have to learn some GRASS first. Things yet to do in the ebuild: * remove commented out portions from older ebuild * try to get rid of env file, to avoid clobbering the environment Can anybody provide reasons for the different environment settings therein? * consider installing to /opt instead of /usr, but read FHS first
Added to the tree, modified somewhat...
