Build failure: gcc extension __always_inline__ is unimplemented on certain linux arm gcc

[Kimmo Kinnunen]

Compilation for arm linux fails for files  where ALWAYS_INLINE is used. 

Compiler: sbox-arm-linux-gcc (GCC) 3.4.4 (release) (CodeSourcery ARM 2005q3-2)

The optimization level is -O2 -g, so this shouldn't be related to the GCC bug caused by using -O0. (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17248)

Further info:
23:32 < alp> Kompo: i can reproduce your inline problem. seems to be caused by passing -fomit-frame-pointer

Do you still have the compile error to post here?

Is this still an issue?

[Kimmo Kinnunen]

No, not valid anymore.
