git 2.25.1_0 +credential_osxkeychain +diff_highlight +doc +pcre +perl5_28]: fails to install, 'unistd.h' file not found

Reported by: jlargentaye (John de Largentaye) Owned by: ci42
Priority: Normal Milestone:
Component: ports Version:
Keywords: xcode12 Cc:
Port: git

Description

Upgrading Git on Cataline 15.3, with a developer seed of XCode 12 & associated CommandLineTools.

Of note in the logs:

  • include paths used at compile time, /opt/local/include and /usr/local/include, indeed do not contain the header file unistd.h
  • DEVELOPER_DIR is reported to be DEVELOPER_DIR='/Library/Developer/CommandLineTools' even though, in my environment, it is set to /Applications/Xcode.app/Contents/Developer, and the output of xcode-select -p is also {/Applications/Xcode.app/Contents/Developer}}} (and the path exists)

Additionally, unistd.h exists at various locations in SDKs under /Library/Developer/CommandLineTools and /Applications/Xcode.app/Contents/Developer. Specific paths can be provided on request.

Replying to jlargentaye:

Upgrading Git on Cataline 15.3, with a developer seed of XCode 12 & associated CommandLineTools.

Of note in the logs:

  • include paths used at compile time, /opt/local/include and /usr/local/include, indeed do not contain the header file unistd.h

That is correct. It is a system header. It is not provided by MacPorts.

We should fix the build so that it does not look in /usr/local/include.

  • DEVELOPER_DIR is reported to be DEVELOPER_DIR='/Library/Developer/CommandLineTools' even though, in my environment, it is set to /Applications/Xcode.app/Contents/Developer, and the output of xcode-select -p is also /Applications/Xcode.app/Contents/Developer (and the path exists)

That is correct. That is an intentional change as of MacPorts 2.6.0.

Additionally, unistd.h exists at various locations in SDKs under /Library/Developer/CommandLineTools and /Applications/Xcode.app/Contents/Developer. Specific paths can be provided on request.

Does /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk exist? Because that's where MacPorts is going to look for system headers on your system. Make sure that you have command line tools for macOS 10.15 installed; it should provide that SDK.

Note that we can't really help with prerelease software. If you can't get it to work with Xcode 12 preview, use Xcode 11.4 which should work.
