strange error...

any idea why you are not getting the prebuilt libgcc12 binary?

​https://packages.macports.org/libgcc12/libgcc12-12.1.0_6+stdlib_flag.darwin_21.arm64.tbz2

[adamgao1996]

Thanks for the fast reply.

where should i put the prebuild file?

Just for documentation purpose:

My mac system is version 13.0 Beta (22A5311f)

I installed macport from source code in folder /opt

[kencu (Ken)]

OK, that's why you didn't get the binary for darwin 21 -- you're on darwin 22 :>

If you can, please zip up and attach the log.

[kencu (Ken)]

I'm not sure if gcc12 builds on darwin 22 yet. You could check with the darwin maintainer directly:

​https://github.com/iains

and open an issue with him there in his gcc12 repo -- you'll get a much faster and probably accurate response directly from Iain.

[adamgao1996]

thanks.

The same ld assertion failure is seen on macOS 12.6 x86_64 when building libgcc12 (or libgcc-devel, ticket:65850) from source with Xcode 14.0, so this is not specific to macOS 13 or arm64.

[mopihopi]

libgcc12 @12.2.0_0 build from source on macOS 12.6 x86_64 with Xcode 14.0

[mascguy (Christopher Nielsen)]

Related ticket, for libgcc-devel: issue:65850

[michaelld (Michael Dickens)]

I've seen this and #65850 for a while ... I did a little code poking ... my best guess is that GCC's build system needs to be tweaked for Darwin 22 ... just a guess. I have not yet contacted Iain yet ... maybe @kencu can do that? Lack of GCC is holding back critical ports when using Xcode 14 or (so I understand) macOS 13-beta + Xcode 14-beta ... like OpenBLAS, NumPy, SciPy, etc. ...

[kencu (Ken)]

[ttelford (Troy Telford)]

I've had this issue for a while, and I can say exactly why I can't use the prebuilt binary: Unavoidable corporate proxy forbids access to the prebuilt versions.

I see the error from macOS 12.5.1

[matteocorti (Matteo Corti)]

With the latest beta of the Xcode command line tools (Command Line Tools for Xcode 14.1 beta 3, September 27 2022) the problem is solved.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #65943.

[soapdog (Andre Alves Garzia)]

This is still happening on macOS Ventura with Xcode 14.1 RC 2 with the Command Line Tools reinstalled after installing the RC 2.

Even though the version numbers in the command-line tools in Xcode 14.1 RC 2 and the downloadable RC 2 CLT-only package from Apple are the same, this package will fail to build with the one bundled in Xcode and build successfully with the one from the CLT-only package. It is very strange since in theory they're the exact same dev tools.

[cjones051073 (Chris Jones)]

This issue now appears resolved, as gcc12 builds fine using the latest Xcodes on macos 12 and 13
