Dear All, I'm trying to call PJSUA APIs to create and destroy a session, but while compiling my application I'm receiving the following error. Code snippet attached. Can anybody tell me whether I'm missing anything? /tmp/ccltDfSK.o: In function `error_exit(char const*, int)': myapp2.cpp:(.text+0x8e): undefined reference to `pjsua_perror' myapp2.cpp:(.text+0x93): undefined reference to `pjsua_destroy' /tmp/ccltDfSK.o: In function `main': myapp2.cpp:(.text+0xc2): undefined reference to `pjsua_create' myapp2.cpp:(.text+0xf9): undefined reference to `pjsua_destroy' collect2: ld returned 1 exit status Thanks & Regards, - Senthil -------------------------------------------------------------------- mail2web.com ?
