Problem: Although eautoreconf is ran from the ebuild, ./unix/configure is sometimes not rebuilt from ./unix/configure.in, so the fontconfig/freetype underlinking fix in the ebuild does not get into ./unix/configure, causing build failures when I use ld.gold. On my pretty fast computer with /var/tmp/portage on tmpfs, the chance of the failure is around 70%. I suspect the problem is related to timing. This may not actually a problem of dev-lang/tk, but I'm only seen it happening on the ebuild. Details: 1. I upgraded @world, as usual, yesterday, when I found dev-lang/tk-8.5.13 didn't build, with many error messages like "undefined reference to 'FcPatternGetInteger'". 2. As I'm using ld.gold, my first impression is there's a underlying issue in the software. Build logs shows it uses -lXft when linking but lacks -lfontconfig. 3. When I looked at the ebuild, I found it already modifies configure.in then run eautoreconf to correct the underlinking problem. 4. I looked at the build directory. Surprisingly I found ./unix/configure.in has been updated with the fix of the underlinking issue, but ./unix/configure wasn't rebuilt correctly. 5. As it only happens sometimes (70% chance here?), and I have a pretty fast/costly computer, with /var/tmp/portage on tmpfs, the first thing I suspect is timestamps. So I inserted a `stat unix/configure*` call into the build, before the eautoconf part started running. I found no significant difference between the stat output when the configure script is correctly rebuilt and when it isn't. When it fails: ---- * Applying tk-8.5.10-conf.patch ...

My workaround: My temporary workaround is to drop ./unix/configure before running eautoreconf, to make sure it always gets rebuilt. I will shortly attach the build logs. Reproducible: Sometimes Steps to Reproduce: 1. Use ld.gold instead of ld.bfd to expose underlinking problems. 2. emerge '=dev-lang/tk-8.5.13' 3. Actual Results: Sometimes (70% chance here), ./unix/configure.in contains the fix of the underlying problem, ./unix/configure isn't updated (its modification time is smaller than ./unix/configure.in.) It doesn't build, with tons of "undefined reference" errors to fontconfig functions. Expected Results: ./unix/configure should always be rebuilt from ./unix/configure.in (I use the LD_ALTEXEC patch to run ld.gold indirectly, so it shows as "GNU ld" while I'm in fact using "GNU gold (GNU Binutils 2.23.1) 1.11".)

So, basically the problem lies in tcl-8.5_alpha6-multilib.patch.
(In reply to comment #3) > So, basically the problem lies in tcl-8.5_alpha6-multilib.patch. Hmm, yeah, it's a bit weird that tk-8.4.11-multilib.patch modifies both ./unix/configure and ./unix/configure.in, but can't there be a more reliable solution, like dropping ./unix/configure before running autoconf, either in the ebuild or in autotools.eclass? Also, I couldn't understand why when the difference in modification time of those two files is always around 0.02 second, it sometimes works but sometimes fails.
I am also using tmpfs but never see such problems. anyways, I will drop the modification from configure so that the timestamp keeps to be old.
