Hello, I have tested pjsip 2.0 on device iPhone 4 with Xcode 5.0 without problem. But by testing on the Simulator, I got this error message by app_init()-> pjsua_create() Does anyone here also have the same problem, how to solve is then? Compiling using: export DEVPATH=/Developer/Platforms/iPhoneSimulator.platform/Developer export CC=/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc CFLAGS="-O2 -m32 -miphoneos-version-min=4.3" LDFLAGS="-O2 -m32" ./configure-iphone make Thanks Regards, -------------- next part -------------- An HTML attachment was scrubbed...
