I don't know what VLCkit is (but now I do - https://wiki.videolan.org/VLCKit/ ),
but normally you can see the entire output (including the clang/gcc/etc.
command line) by doing  the following:

	$ make 2>&1 | tee ~/make.output.txt

Or:

	$ make VERBOSE=1 2>&1 | tee ~/make.output.txt

Are you using Mac OS X?
