Today I decided to try out the ~amd64 dev-lang/erlang-13.2 package, it worked fine until I tried to run a program using the new wxwindows support. Specifically: the debugger. The directory mentioned in the error doesn't exist. However the parent directory does (and it contains ebin, src and so on as expected). Reproducible: Always Steps to Reproduce: 1. emerge dev-lang/erlang-13.2 with the wxwindows USE flag turned on. In a shell: 2. erl In Erlang shell: 3. toolbar:start(). 4. Click the debugger button in the toolbar that pops up. 5. Observe the old Tk window opens and the error in the terminal. In a normal shell: 6. ls /usr/lib64/erlang/lib/wx-0.98.1 Actual Results: $ erl Erlang R13B (erts-5.7.1) [source] [64-bit] [rq:1] [async-threads:0] [hipe] [kernel-poll:false] Eshell V5.7.1 (abort with ^G) 1> toolbar:start(). <0.34.0> 2> =ERROR REPORT==== 23-Apr-2009::21:53:04 === WX ERROR: Could not find suitable 'wxe_driver' for x86_64-pc-linux-gnu in: /usr/lib64/erlang/lib/wx-0.98.1/priv ^C BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded (v)ersion (k)ill (D)b-tables (d)istribution a $ ls /usr/lib64/erlang/lib/wx-0.98.1 ebin examples include src Expected Results: The error should not show up, and the directory mentioned should exist (and contain something). # emerge -pv erlang These are the packages that would be merged, in order: Calculating dependencies... done!

Found some more details when manually compiling it: checking for wxWidgets version >= 2.8.0 (--unicode)... no (version 2.6.4 is not new enough) configure: WARNING: wxWidgets must be installed on your system. Please check that wx-config is in path, the directory where wxWidgets libraries are installed (returned by 'wx-config --libs' or 'wx-config --static --libs' command) is in LD_LIBRARY_PATH or equivalent variable and wxWidgets version is 2.8.0 or above. But: [I] x11-libs/wxGTK Available versions: (2.6) 2.6.4.0-r4 (2.8) 2.8.9.1-r3 ~2.8.9.2 ~2.8.9.2-r1 Both are installed. The ebuild should be able to select the right one as far as I can see. Hope this is fixed soon.

Installed versions: 2.6.4.0-r4(2.6)(13:26:25 10/17/08)(X opengl sdl unicode -debug -doc -gnome -odbc -pch) 2.8.9.1-r3(2.8)(00:28:07 01/20/09)(X gstreamer opengl sdl -debug -doc -gnome -odbc -pch) Is more relevant.
Thanks for your report. Could you please tell me what the output of eselect wxwidgets list is?
# eselect wxwidgets list Available wxWidgets profiles: [1] gtk2-ansi-release-2.6 [2] gtk2-unicode-release-2.6 * [3] gtk2-unicode-release-2.8 As far as I remember, ebuilds are supposed to select the ones they need using some eclass, the eselected one only being used for out-of-portage builds.

Yes, I know, but I wanted to be sure, that you really have something different from 2.8. So thanks for the information, will update the ebuild today.
Should be fixed now, remerge and report back please.
I don't think you can do it like you did for conditional wxwidgets support. I believe it will now require wxwidgets to be available even with USE=-wxwindows I'm not sure what exactly must be done for that offhand, but at least it seems you should have your own pkg_setup that overrides wxwidgets_pkg_setup because that one seems to make an unconditional check for wxGTK existence. Maybe we shouldn't export pkg_setup with EAPI=2, hmm... CCing wxwidgets@ to make sure my thoughts are right for erlang ebuild changes - dirtyepic, can you comment? Maybe we should discuss on IRC with dirtyepic about conditional use of wxwidgets and document how to do that in the eclass
it only checks during pkg_setup if WX_GTK_VER is set before inheriting the eclass AND you only have wxBase installed. it's to catch some corner case Diego came up with. so yes, if wxGTK was built with USE=-X and erlang is emerged with USE=-wxwindows you'll still get a error. i think overriding pkg_setup should work but i haven't looked at it too hard yet. i'll poke at it later today.
pkg_setup() { use wxwindows && wxwidgets_pkg_setup } Is my proposal
(In reply to comment #9) > pkg_setup() { > use wxwindows && wxwidgets_pkg_setup > } > > Is my proposal And I go with that.
good enough for me ;)
