m4: configure: error: Cannot find a type to use in place of socklen_t

I got the following error when trying to install m4 on Mac Sequoia 15.0.1:

Any suggestions on how to fix the issue?

Please attach the main.log and config.log files.

Hereby the log files!

The main.log says the problem is:

:info:configure checking for socklen_t... no
:info:configure checking for socklen_t equivalent... configure: error: Cannot find a type to use in place of socklen_t

The config.log says the reason for that is:

configure:57981: checking for socklen_t
configure:57981: /usr/bin/clang -c -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk -arch arm64 -I/opt/local/include -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk conftest.c >&5

This looks like #62991 (and the same issue for grep in #64135) which were both fixed but the fix was only for when the universal variant is used. Your log shows you are not using the universal variant. However I do see this in your main.log:

:debug:sysinfo macOS 15.0.1 (darwin/24.0.0) arch i386

Are you on an Intel Mac or an Apple Silicon Mac? This line indicates MacPorts thinks you are on an Intel Mac, but the log shows you are trying to build m4 for Apple Silicon (arm64).

If you're on an Intel Mac, you won't be able to run arm64 software at all, so I assume you're on an Apple Silicon Mac. In that case, this problem is typically caused by running the Intel version of MacPorts, which happens automatically if you're running an Intel shell, which happens automatically if you're running an Intel terminal program. The solution is to use an Apple Silicon terminal program, like the one Apple includes with macOS at /Applications/Utilities/Terminal.app.

If you're already using Apple Terminal or a third-party terminal that is compiled for Apple Silicon, then go to the Finder, click the terminal program's icon, choose Get Info from the File menu, and see if the Open in Rosetta checkbox is checked. If it is, uncheck it, then close and reopen the terminal program.

This might be solved by [eee437c415b4e1d17eeb57fecff633f1d3846ffd/macports-base] which will be included in a future version of MacPorts.

Thanks a lot for looking into this and your feedback! I am indeed using Apple Silicon and had launched the Terminal with the Rosetta checkbox ticked. Running the Terminal without Rosetta solved the issue :-). Thanks again!
