When running an emerge, i get the following output: ar cru .libs/libimlib2_filter.a imlib2_filter.o ranlib .libs/libimlib2_filter.a creating libimlib2_filter.la (cd .libs && rm -f libimlib2_filter.la && ln -s ../libimlib2_filter.la libimlib2_filter.la) gcc -march=athlon-xp -O3 -pipe -I/usr/X11R6/include -o camserv camconfig.o camserv.o filter.o main_loop.o picture_loop.o shm.o video.o -Wl,--export-dynamic ../libltdl/.libs/libltdlc.al -ldl ../common/libcommon.a -lnsl /usr/lib/libjpeg.so -lm camserv.o(.text+0x352): In function `main': : undefined reference to `errno' camserv.o(.text+0x503): In function `main': : undefined reference to `errno' main_loop.o(.text+0xc87): In function `main_loop': : undefined reference to `errno' main_loop.o(.text+0xcaf): In function `main_loop': : undefined reference to `errno' picture_loop.o(.text+0x242): In function `picture_single': : undefined reference to `errno' collect2: ld returned 1 exit status make[1]: *** [camserv] Error 1 make[1]: Leaving directory `/var/tmp/portage/camserv-0.5.0/work/camserv-0.5.0/camserv' make: *** [all-recursive] Error 1 !!!

Created attachment 18053 [details, diff] proposed camserv-errno patch This patch can be applied against both camserv-0.5.0 and camserv-0.5.1.
manual make ; make install works good here after patching 0.5.1. Thanks!
is this still an issue? please provide #emerge info
Added the patch to CVS and changed 0.5.0 and 0.5.1-r2 accordingly (no revision bump since this is a compile time issue). I think Brandy should close this.
my manual compile was segfaulting on me. just ran emerge sync, and attempted to rebuild of 0.5.1-r2. still seems to not be working, same error.

Why did you not paste the top section of "emerge info" with the version information? It works fine on my athlon xp system with the same CFLAGS as you have, so I guess it must have some other reason.
Gah, my bad. Apparently my paste skills are lacking. Portage 2.0.49-r3 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r1, 2.4.20-gaming-r3) ================================================================= System uname: 2.4.20-gaming-r3 i686 AMD Athlon(tm) XP 2200+ ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=athlon-xp -O3 -pipe" Was this patch added to the portage tree? I didn't see it try to patch it.
The only important differences I see between our machines are: I use gcc 3.2.3-r1 and vanilla kernel. Yes, camserv 0.5.0 and 0.5.1-r2 should both apply the errno patch when you are synced with a functional portage mirror.
Could you please recompile latest camserv with CFLAGS="-g", FEATURES="nostrip", run it from gdb and do a backtrace when it segfaults?
added patch in all ebuilds
