Hi, I am just having a dumb question and hoping someone can help me. I am trying to run a c program with libfreeswitch embedded so I can use some external mechanism to keep track of freeswitch, but I am having problem while compiling: [root@localhost fs]# gcc switchnode.c -I/usr/local/freeswitch/include -L/usr/local/freeswitch/lib -lfreeswitch -lpthread switchnode.c: In function 'main': switchnode.c:11: warning: passing argument 1 of 'switch_core_init_and_modload' makes integer from pointer without a cast switchnode.c:11: warning: passing argument 3 of 'switch_core_init_and_modload' from incompatible pointer type /usr/local/freeswitch/lib/libfreeswitch.so: undefined reference to `clock_gettime' /usr/local/freeswitch/lib/libfreeswitch.so: undefined reference to `uuid_generate' /usr/local/freeswitch/lib/libfreeswitch.so: undefined reference to `crypt_r' collect2: ld returned 1 exit status [root@localhost fs]# Does anyone know which library is missing? Thanks, Woody
