Hi Arcady. Sorry if I assigned the bug wrongly, but you seem to be the most prominent on the xine-lib bugs. Oh, and I did not find this reported either, although there are bunch of xine-lib related bugs. I hope I did not overlook something.. Apparently xine-lib (-1_rc1) does not like -fpmath=sse in CFLAGs, at least on pentium3. Build with -fpmath flag omitted proceeds fine.

I can verify the same thing happens with my p3. Removing -mfpmath=sse allows it to compile.
I can confirm it on a P4 2Ghz. Remove -fpmath=sse in CFLAGS works great. I remove the -msse2 flasg too for sure...
You should use "-mfpmath=sse,387" instead. This solves stability issues and compilation errors on a lot of things. No problems compiling xine-lib with that flag. You will also have to filter -fforce-addr.

This isn't working for me.

Heh, looks like this is a bug in gcc: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13850 fixed by using CFLAGS="-O" of all things.

Created attachment 29404 [details, diff] xine-lib.diff This patch allows the ebuildto filter -fforce-addr which make xine-lib not compilable. It owrks well using this.

Julian, which gcc version?

-fpmath=sse is filtered now
I have successfully built xine-lib with these CFLAGS: CFLAGS="-march=athlon-xp -O3 -mfpmath=sse -fforce-addr -fomit-frame-pointer -funroll-loops -pipe" But it always fails with these CFLAGS: CFLAGS="-march=athlon-xp -O3 -mfpmath=sse -fforce-addr -fomit-frame-pointer -funroll-loops -funroll-all-loops -fprefetch-loop-arrays -maccumulate-outgoing-args -pipe" i.e. xine-lib successfully builds, when I remove "-funroll-all-loops -fprefetch-loop-arrays -maccumulate-outgoing-args" from my CFLAGS. Hope it helps! :)
