Xcode version must be specified to use an Apple CROSSTOOL

Question

I try to build tensorflow-serving using bazel but I\'ve encountered some errors during the building

ERROR:/private/var/tmp/_bazel_Kakadu/3f0c35881c95d2c43f04614         


        

Answer 1

It looks like xcode_configure isn't properly identifying that you have xcode installed. This can sometimes happen if you install xcode but have not yet fully opened it (it may ask you to agree to Terms and Conditions before being fully functional). If this is the problem, you'll need to bazel clean --expunge again after that...

If this doesn't help, you can get some debug information to identify what's gone wrong, by invoking (after a failed build):

cat $(bazel info output_base)/external/local_config_xcode/BUILD

This should contain some comments pertaining to failures in finding your installed xcodes.
