What did you do?

Ran GO111MODULE=on go get github.com/onsi/ginkgo/ginkgo. I tried go getting other packages, but got the same output.

What did you expect to see?

I expected to get no output and the package to successfully install.

What did you see instead?

The following output was given to me:

go: finding github.com/onsi/ginkgo/ginkgo latest
# runtime/cgo
xcrun: error: unrecognized option: -E
Usage: xcrun [options] <tool name> ... arguments ...

Find and execute the named command line tool from the active developer
directory.

The active developer directory can be set using `xcode-select`, or via the
DEVELOPER_DIR environment variable. See the xcrun and xcode-select manual
pages for more information.

Options:
  -h, --help                  show this help message and exit
  --version                   show the xcrun version
  -v, --verbose               show verbose logging output
  --sdk <sdk name>            find the tool for the given SDK name
  --toolchain <name>          find the tool for the given toolchain
  -l, --log                   show commands to be executed (with --run)
  -f, --find                  only find and print the tool path
  -r, --run                   find and execute the tool (the default behavior)
  -n, --no-cache              do not use the lookup cache
  -k, --kill-cache            invalidate all existing cache entries
  --show-sdk-path             show selected SDK install path
  --show-sdk-version          show selected SDK version
  --show-sdk-build-version    show selected SDK build version
  --show-sdk-platform-path    show selected SDK platform path
  --show-sdk-platform-version show selected SDK platform version

It looks like you have CC and CXX set to xcrun. How are those set? Is that intentional?

The go command uses the C compiler to type check and build cgo code. The program that CC points to must have a command line interface similar to gcc or clang, and it must print errors in the same format.

Oh well that's interesting:

$ echo $CC
xcrun clang
$ echo $CXX
xcrun clang++

not sure how it was set though, but I am guessing the xcrun should be omitted?

EDIT:

and wouldn't you know it

export CC=clang
export CXX=clang++

solve the problem. How does that get set. Maybe it's something I installed?

Not sure how those would have been set. Maybe check .profile, .bashrc, or related files?

I'll close this since it seems to be working.
