As I described - configure can't compile conftest.c stub (with the purpose of testing of existance of the library libcomm_err) because there are unresolved loader references, and as a result: fatal error: > checking for error_message in -lcom_err... no So how/where your config finds sem_* symbols functions ? or mebe your libcom_err is self-contained and does not reference them ? On my fresh Fedora 16 -pthread cc option must be definded becasue libcom_err is not self-contained and needs sem_* symbols which option -pthread provides.
