Hello, In the last step of building ghostscript 6.5 (after some minor modifications in a few places) I encountered the following error message: (while gcc -fno-common -o ./bin/gs ./obj/gs.o ./obj/gp_getnv.o ...) ./obj/gp_psync.o(.text+0x49):gp_psync.c: undefined reference to `pthread_cond_init' ./obj/gp_psync.o(.text+0x7a):gp_psync.c: undefined reference to `pthread_cond_destroy' ./obj/gp_psync.o(.text+0xda):gp_psync.c: undefined reference to `pthread_cond_wait' ./obj/gp_psync.o(.text+0x148):gp_psync.c: undefined reference to `pthread_cond_signal' ./obj/gp_psync.o(.text+0x28e):gp_psync.c: undefined reference to `pthread_attr_setdetachstate' I have /usr/include/pthread.h but can not find libpthread.a anywhere. Any help is appreciated. Wei Ku -- Want to unsubscribe from this list? Check out: http://cygwin.com/ml/#unsubscribe-simple
