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

Had the same problem, and since I am using a beta version of XCode, I had to find the installation in /Downloads/Xcode-beta.app instead.

Incidentally, the solution for me was to open XCode, go to Preferences, and select the Locations tab. The Command Line Tools drop-down was blank, and I had to press it and select a version (Xcode 9.0 in my case). I then ran bazel clean --expunge and repeated the build process without getting the error. Hope this helps someone.
