Question

I am trying to compile a c++ project into a lib, using Xcode 4.6. Also it is a wxWidgets project I chose C/C++ Library when build the project then I and my files and click build, the error like this

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool failed with exit code 1
