I guess that you assume this work if you have compiled chakracore already? And don't include ChakraCore in xcode?

hi @obastemur

chakracore.xcodeproj and chakrashim.xcodeproj are both included and compile by xcode successfully

[obastemur]

chakracore.xcodeproj and chakrashim.xcodeproj are both included and compile by xcode successfully

They are there because of chakracore.gyp and chakrashim.gyp are exist. ChakraCore build system is CMake. You can't create chakracore's xcode project by exporting xcode from gyp.

Besides, the changes to configure needs some attention.

Thanks for the attempt.

This; being automated, may require a bit more hacking.
