Description
PROBLEM The cdda2wav program, part of the cdrtools 2.01 port, fails to link on Darwin 8.1.0 (Mac OS X 10.4) with the error:
... /usr/bin/ld: warning prebinding disabled because of undefined symbols /usr/bin/ld: Undefined symbols: _sched_setscheduler collect2: ld returned 1 exit status gnumake[1]: * [OBJ/powerpc-darwin-cc/cdda2wav] Error 1 ...
The port continues to build and is installed successfully, with the exception of cdda2wav.
CAUSE System function sched_setscheduler is not available in Darwin 8.1.0; in /usr/include/unistd.h, _POSIX_PRIORITY_SCHEDULING is defined to be -1. However, in cdda2wav.c there is only a check whether _POSIX_PRIORITY_SCHEDULING is defined or not, its value is not tested; if defined, a call to sched_setscheduler is included in the code.
SOLUTION Extend the check of _POSIX_PRIORITY_SCHEDULING with a test of its value, for example:
