Even the simplest command-line compiler examples from Rory's paper and Mike's reference manual won't compile for me, using gcc nor g++. I discovered that, while they use functions like csoundCreate(), csoundDestroy(), csoundPerformKsmps(), etc, all of these functions are only declared in csound.h, or any of the files in csound5/H/ . I only seem them defined in Top/main.c and Top/csound.c . This is exactly what the compiler tells me, that the functions are undefined. Am I doing something wrong? Also wondering, is there a quick way on Linux to add the Csound H/ folder to the places gcc checks without installing Csound? Thanks a lot. -Chuckk -- http://www.badmuthahubbard.com
