trying to link agains libsdl gives this: /usr/lib/libSDL.so: undefined reference to `_MMX_UbluRGB' /usr/lib/libSDL.so: undefined reference to `_MMX_Vred5x5' /usr/lib/libSDL.so: undefined reference to `_MMX_VgrnRGB' /usr/lib/libSDL.so: undefined reference to `_MMX_grn565' /usr/lib/libSDL.so: undefined reference to `_MMX_VredRGB' /usr/lib/libSDL.so: undefined reference to `_MMX_Vgrn565' /usr/lib/libSDL.so: undefined reference to `_MMX_FF00w' /usr/lib/libSDL.so: undefined reference to `_MMX_Ugrn565' /usr/lib/libSDL.so: undefined reference to `_MMX_Ycoeff' /usr/lib/libSDL.so: undefined reference to `_MMX_UgrnRGB' /usr/lib/libSDL.so: undefined reference to `_MMX_00FFw' /usr/lib/libSDL.so: undefined reference to `_MMX_red565' /usr/lib/libSDL.so: undefined reference to `_MMX_0080w' /usr/lib/libSDL.so: undefined reference to `_MMX_Ublu5x5' This is because of the patch from bug 75392. Better patch that works for both gcc2 and gcc3 follows.
Created an attachment (id=54317) [edit] 1.2.8-gcc2-asm.patch from http://www.devolution.com/pipermail/sdl-cvs/2005-February/000767.html
added to portage, thanks :)
the logic to apply the old 1.2.8-gcc2-asm.patch only on gcc2 in the ebuild should be removed as its no longer needed and it is broken if they are both applied. * Applying libsdl-1.2.8-gcc2.patch.bz2 ... [ ok ] * Applying 1.2.8-keyrepeat.patch ... [ ok ] * Applying 1.2.8-linux26.patch ... [ ok ] * Applying 1.2.8-amd64-endian.patch ...

whoops, i didnt notice because i have gcc-2 :) fixed in cvs, sorry about that
This patch causes the compile of libsdl-1.2.8-r1 to fail when compiling with GCC 3.4.3. See this bug report: http://bugs.gentoo.org/show_bug.cgi?id=87077 There is a fix that involves disabling a compile flag, but that is a hack for a bad patch. This patch is flawed and needs fixing. I suggest disabling it for gcc versions greater than 3.4.
Remove the volatiles added in the top section of the patch and it compiles with -fforce-addr on gcc-3.4.3 (bug 87077) and still works with gcc2. This patch is from upstream, and I don't know if they had a reason for adding volatile or not, or if they support using -fforce-addr.
