Hello everyone! I am very new to both PJSIP and mobile development, therefore I apologize if my questions will sound naive or just downright wrong. I would like to be able run the iPhone application which uses PJSIP libraries in the iPhone simulation environment provided by Xcode. I would imaging that for that I need to be able to build the PJSIP libraries for the x86/64 (Intel type architecture) target. To support that theory if I build an application for the simulator target in Xcode while PJSIP libraries are build for the ARM[x] target I am getting a bunch of warnings and consequently unresolved errors all due to the fact that each and every library "is ignored due to the fact that it is archived for the architecture different from the i386 build target". I would say it all makes sense. Unfortunately I was not able to find the right architecture parameter setting in order to be able to build for the Intel processor. Even the most expected to work x86_64 (ARCH='-arch x86_64') was getting rejected as not supported by the clang compiler: ARCH = x86_64 checking build system type... x86_64-apple-darwin14.5.0 checking host system type... x86_64-apple-darwin_ios checking target system type... x86_64-apple-darwin_ios checking for x86_64-apple-darwin_ios-gcc... /Applications/XCode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/../../../Toolchains/XcodeDefault.xctoolchain/usr/bin/clang checking whether the C compiler works... no aconfigure: error: in `/Users/ybrenman/iOS/pjproject-2.4.5': aconfigure: error: C compiler cannot create executables Needless to say I tried a lot of other combinations and permutations like i386, etc. Having said that obviously Xcode toolchain is perfectly capable of building the iPhone application code for Intel processor architecture. Clearly, I am missing something simple. And I am sure I am not the first one to do this. But just can't figure out what. Every bit of help is greatly appreciated Carlos -------------- next part -------------- An HTML attachment was scrubbed...
