I see. Thanks for the info. I thought, let’s build gcc14 from source then, but that fails.

I’ve seen this before on a port. When downloading a binary, it works. But trying to compile yourself fails. I’ve started to suspect that MacPorts is not a very certain route when compiling yourself is part of the mix. Anyway, building with MacPorts from source seems to use /Library/Developer/CommandLineTools/SDKs and not /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/ Developer/SDKs, and there I can find de 14.x SDK.so I might try the compiled version with that -isysroot G > On 13 Feb 2025, at 12:46, Chris Jones via macports-users > <macports-users@lists.macports.org> wrote: > > Hi, > > Looks like its this > > https://github.com/iains/gcc-14-branch/issues/7 > > Basically, GCC is sensitive to the SDK it was built against.
