Re: [Protux-devel] cant find correct place to add -D_XXXXXXX

[Luciano Giordana]

Thanks a lot . It is working fine for libmustux, but now I have to manually ad 
-lasound into protux so I can compile it with ALSA

if I dont put it I get

this is strange, because there are no direct calls to alsa from protux. the 
-lasound in libmustux should be enought right ?
