Description Hans de Goede 2010-06-24 01:24:22 UTC 
Hi,

SDL_mixer uses pow (in timidity/instrum.c), so it should be linked with -lm. As SDL_mixer links against SDL, which in turn is linked against -lm this is normally not a problem. But with the recent changes to gnu ld's rule form implicit dso linkage this can cause compile errors for programming using SDL_mixer, see:

Regards,

Hans
