Hey, I wan able to compile a hello world program by saving the file in C:/pjproject-1.3/pjsip-apps/src/pjsua and compiling in the MSYS ( shell prompt ) as gcc -c hello.c and it displays the output "Hello world!" But how do I do the same with simple_pjsua.c file? Any help would be great! -------------- next part -------------- An HTML attachment was scrubbed...
