Bugzilla Bug 148186

Since libSDL-1.2.11 all programs using SDL fail to compile complaining about an
unresolved refetence to 'BlitRGBtoRGBPixelAlphaMMX3DNOW'. In file
src/video/SDL_blit_A.c lines 2817 - 2829 there's an autodetection for my CPU's
capabilities:
                {
                        if(SDL_Has3DNow())
                                return BlitRGBtoRGBPixelAlphaMMX3DNOW;
                        if(SDL_HasMMX())
                                return BlitRGBtoRGBPixelAlphaMMX;
                }
where 'if(SDL_Has3DNow())' seems to return true, which is clearly wrong: cat
/proc/cpuinfo | grep ^flags returns 'fpu vme de pse tsc msr pae mce cx8 apic
sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx
constant_tsc pni monitor vmx est tm2 xtpr'
Hacking the code to always return the non-3dnow function
BlitRGBtoRGBPixelAlphaMMX solved my errors.
There's also some other guy having the same problem:

*** Bug 144828 has been marked as a duplicate of this bug. ***

i'm pretty sure the bug here is that BlitRGBtoRGBPixelAlphaMMX3DNOW is declared
as inline ... it has nothing to do with misdetection of CPU as the failure
you're seeing is at *linktime* and that code is not executed until *runtime*

so try editing src/video/SDL_blit_A.c, go to the definition of
BlitRGBtoRGBPixelAlphaMMX3DNOW(), and remove the 'inline' keyword

Removing the inline keyword did the job, both sdl-image and quake2-icculus do
emerge now without errors.

that doesnt really satisfy my curiosity as to why you are seeing this problem

that function is declared static so the symbol should not be exported thus
linking against it shouldnt be a problem ...

can you post: `emerge -pv libsdl`

I reemerged it without changes to find out more about it.

oh well, we'll just call it a day ... no time to investigate this further ;(
