Question

I’ve downloaded some source code from Apple open source repository.
The projects are .pbxproj files which I can open in XCode.
But I need to export the project to a Makefile/Configure configuration.

I’ve googled around and found some comments about pbxbuild but could
not find a download link and I’m not sure it is what I need anyway.

Also I tried a tool called pbtomake which failed on the project file.
I guess it’s too old.

pbxbuild is obsolete – you need xcodebuild:

$ man xcodebuild
