I’m using QNX RTP on intel machine and can’t get the wave.c example in the
help to compile, basically it gives the following errrors:

…From what I can see it basically can’t find these functions, and yet I
know they’re there…

Any suggestions would be greatly appreciated

Make sure you are including the library libasound.so when you compile ie:
qcc wave.c /lib/libasound.so
