oc fails to build on macOS with "Unknown type name gss_const_name_t"

[c3d]

Not sure exactly if I'm doing anything wrong. The same source version builds on Fedora32 without a problem:

Go version 1.14.2_1 from Homebrew, if that's relevant. Catalina 10.15.4.

[c3d]

Apparently this is a known issue. There seems to be a hack to build some headers, need to manually install them I guess.

#cgo darwin CFLAGS: -I/opt/local/include -I/usr/local/opt/heimdal/include

[c3d]

Used brew install heimdal to get the missing headers, and the build works. Closing.

[jwmatthews]

In addition to installing heimdal, had to explicitly call out the include path:

CGO_CFLAGS="-I/opt/homebrew/opt/heimdal/include" make oc

compiled successfully with above on macos arm64

Thanks @jwmatthews !! worked like a charm
