Hey Ben.

Just to make sure from what I'm gathering the includey statements go in the top lines of your .c program. I'm using the lores~.c as given in the sdk.. which does include this #include "z_dsp.h" at the top. Is this what your talking about? I'm following the steps given in the Cygwin_gcc_Howto.rtf manual exactly except replacing minimimum wiht lores~ and adding the additional lines -I../../c74support/msp-includes in step 1 and -L../../c74support/msp-includes in step 2

perhaps having the two -L in the gcc command is making things weird.

Well, I don't know - I don't have any experience with gcc on cygwin. The gcc builds we do on Mac use the -I flag, not -L -- is it possible that's the problem?

Ben

-I is for headers -L is for libraries.

No it still won't work. I'll have a fresh go at it tommorow... thanks for the help!!!

Ahhhh yeah headers and libraries. Thanks Mark. It finally compiled by entering..

gcc -shared -mno-cygwin -o minimum.mxe minimum.o minimum.def -L../../c74support/max-includes -L../../c74support/msp-includes -lMaxAPI -lMaxAudio

seems I wasnt' linking to the MaxAudio.lib
