Using sem_open, sem_close, sem_post and sem_wait in my c++ file. compiled using command below:
g++ -g -I/opt/sfw/lib/gcc-lib/sparc-sun-solaris2.8/2.95.3/include -L /usr/lib/ -B /usr/lib/sparcv9/libpthread.so hello.cpp -o hello But get the output below: Undefined first referenced symbol in file sem_close /var/tmp/cc9j0Eif.o sem_open /var/tmp/cc9j0Eif.o sem_post /var/tmp/cc9j0Eif.o sem_wait /var/tmp/cc9j0Eif.o ld: fatal: Symbol referencing errors. No output written to hello collect2: ld returned 1 exit status g++: file path prefix `/usr/lib/libpthread.so' never used May I know what is wrong? and how can I find out which library are all these semaphore functions in? The man page doesn't help much :( TIA. _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
