Hi, I'm trying to build PJSIP on Mac OS X 10.4.11 (PowerPC), and got the following error during 'make': ../src/pjmedia/wav_writer.c: In function 'flush_buffer': ../src/pjmedia/wav_writer.c:294: error: 'BYTES_PER_SAMPLE' undeclared (first use in this function) ../src/pjmedia/wav_writer.c:294: error: (Each undeclared identifier is reported only once ../src/pjmedia/wav_writer.c:294: error: for each function it appears in.) make[2]: *** [output/pjmedia-powerpc-apple-darwin8.11.0/wav_writer.o] Error 1 make[1]: *** [pjmedia] Error 2 make: *** [all] Error 1 I checked out wav_writer.c, attempted to change the case (to all lower case) of the constant 'BYTES_PER_SAMPLE', but still got the same error. Searched the list for an answer but couldn't find one. Any ideas? Thanks, Craig
