vox populi vox dei: dvtassertions: assertion failure xcodebuild invoked in Makefile

What can you do to be able to run xcodebuild within a Makefile ?

First lesson I learned is that you can call xcodebuild in the folder where xcodeproj is located using the shell but how to invoke xcodebuild from a Makefile ?

Create top level Makefile and then call various project Makefile next to each xcodeproj.

In top level Makefile create a separate target for xcode

# xcodebuild will fail mysteriously if we have the CC environmental variable set. If we are building xocde target,

# remove any local definition for CC so this won't happen.

ifeq ($(MAKECMDGOALS),olympic)

unexport CC

olympic:

else

xocde:

$(MAKE) -C subfolder/iOS/projectroot xcode

endif

Then in subfolder/iOS/projectroot create a Makefile and add the following

all: xcode

xcode:

xcode-select -print-path < USEFULL to LOG path to xcode

xcodebuild -project myproject.xcodeproj -list < USEFULL to LOG all target available in xcode project

xcodebuild

Open a shell in top level folder where top Level Makefile belongs

and run

make xcode

If you do not unexport CC then you will see following crash in xcodebuild.

APPLE Xcode team: Please FIX this is annoying!!!
