First of all i don't know if this is related to any other arch (or my broken Gentoo?). Also, i'm not sure if it is related to x86 or to some specific x86 environment. I had similar issue some time ago with unmasked glibc-2.14 and i used my system backup thinking "maybe it's too bleeding edge right now". But it seems that this bleeding edge hits me again after rebuilding glibc-2.13-4 today (glibc ChangeLog: 17 Jan 2012 *snip* drop USE=nls). So, what happend? There was sdl-mixer rebuild right after glibc that ended with this: /lib/libdl.so.2: undefined reference to `__environ@GLIBC_2.0' collect2: ld returned 1 exit status make: *** [build/playwave] Błąd 1 make: *** Oczekiwanie na niezakończone zadania.... /lib/libdl.so.2: undefined reference to `__environ@GLIBC_2.0' collect2: ld returned 1 exit status make: *** [build/playmus] Błąd 1 Like i said, i saw something similar before. I search around but found nothing usefull. So i tried to get something (hopefully) usefull from the libdl and i did this from a machine with working glibc (still with the "older" build with nls): wloczykij ~ # readelf -a /lib/libdl-2.13.so | grep environ 00003fe8 00001506 R_386_GLOB_DAT 00000000 __environ 15: 00000000 0 OBJECT WEAK DEFAULT UND environ@GLIBC_2.0 (8) 17: 00000000 0 OBJECT WEAK DEFAULT UND _environ@GLIBC_2.0 (8) 21: 00000000 0 OBJECT GLOBAL DEFAULT UND __environ@GLIBC_2.0 (8) Here's the output of the same command with _broken_ (?!) glibc: maszyn ~ #

On other ~x86 machine and newer glibc the mentioned command looks like this: rekowered ~ # readelf -a /lib/libdl-2.14.1.so | grep environ 00003fcc 00000206 R_386_GLOB_DAT 00000000 __environ 2: 00000000 0 OBJECT GLOBAL DEFAULT UND __environ@GLIBC_2.0 (7) 15: 00000000 0 OBJECT WEAK DEFAULT UND _environ@GLIBC_2.0 (7) 21: 00000000 0 OBJECT WEAK DEFAULT UND environ@GLIBC_2.0 (7) and yeah, it works fine… would be nice to give me some more ideas about this issue.
the symbol is supposed to be defined in libc.so.6: $ readelf -s /lib32/libc.so.6 | grep environ 299: 0019ae00 4 OBJECT WEAK DEFAULT 30 _environ@@GLIBC_2.0 1018: 0019ae00 4 OBJECT WEAK DEFAULT 30 environ@@GLIBC_2.0 1363: 0019ae00 4 OBJECT GLOBAL DEFAULT 30 __environ@@GLIBC_2.0 is it not being defined that way on your system ? please post the full glibc build log as an attachment (compress it if need be).

what does `readelf -d /lib/libdl.so.2 /usr/lib/libglib-2.0.so` show ?

*bump* I would love to solve this issue one way or another. If not here i will try with glibc package from some other machine.
Just noticing that I tried glibc-2.15-r1 and same thing happend.
I'm not sure if this is glibc issue anymore. Tried to install glibc from binhost [1] and after glibc re-emerge it's exacly the same (vim won't find terminal lib, irssi won't find glib and sdl-mixer has the undefined reference). As suggested by one of the devs (Amadeusz Żołnowski / aidecoe [2]) I went through emerge -e @system and emerge -e @world (both with --exclude=glibc) and nothing changes. [1] http://tinderbox.dev.gentoo.org/default-linux/x86/ [2] he hit the same "undefined reference" bug, used his system backup, but after few days/weeks and another try everything went fine for his glibc (or wherever the bug is)
I can see this is not included in emerge --info. Also, don't even know if this is still used, but in my /etc/make.conf (i think on all my Gentoo boxes) i have a line: PORTAGE_STRIP_FLAGS="--strip-unneeded -R .comment -R .note -R .note.ABI-tag" Yesterday I had some time to do random tests with glibc (removed C{,XX}FLAGS and added debug options, added USE="debug", made MAKEOPTS="-j1", #PORTAGE_STRIP_FLAGS) and it seems that everything went fine. Then I reemerged sdl-mixer, irssi and vim without any issues. Then I added/removed some of the flags/optimisations above and it looks like the problem is in the STRIP line. Here's the current output of "readelf -s /lib/libc.so.6 | grep environ": 298: 00178d80 4 OBJECT WEAK DEFAULT 31 _environ@@GLIBC_2.0 1012: 00178d80 4 OBJECT WEAK DEFAULT 31 environ@@GLIBC_2.0 1351: 00178d80 4 OBJECT GLOBAL DEFAULT 31 __environ@@GLIBC_2.0 I will keep sys-libs/glibc-2.13-r4 for a few days and check if everything works without some random issues (maybe even -e @world, who knows ;) and then update to ~arch glibc.
pretty sure .note.ABI-tag is not something you can safely throw away. it contains bits used by the link-time linker (`ld`) and the runtime linker (`ldso`). so if removing that flag is causing you problems, then don't do that. the other flags you specified we already use as the default strip flags.
