[reneeotten (Renee Otten)]

please add the full main.log file mentioned in the error message to this ticket

[wyuenho (Jimmy Yuen Ho Wong)]

The first main.log was uploaded by mistake. Please ignore it.

[ahrex]

Looks like upstream fixed it: ​https://github.com/ziglang/zig/issues/17050

[SpikeLightfoot]

How can I use the "OTHER_LDFLAGS=-ld_classic" workaround within MacPorts?

[sejmann]

I doubt this was the proper way to fix it, but I got it to build/install by editing the Portfile and appending the line:

configure.args-append -DCMAKE_INSTALL_RPATH="${prefix}/libexec/llvm-16/lib" -DCMAKE_EXE_LINKER_FLAGS="-ld_classic"

I guess that workaround won't be necessary once the port is updated to zig 0.12.0

[mrdomino (Jōshin)]

Any reason not to merge that line to the Portfile for now until a new release is cut? Does it break anything?

[Christopher Nielsen <mascguy@…>]

In 2c4d5b80c765202da0f3f599e08f9937d9b7b7ff/macports-ports (master):

zig: use ld_classic for Xcode 15

See: #68281

[wyuenho (Jimmy Yuen Ho Wong)]

Still failing ​https://build.macports.org/builders/ports-14_x86_64-builder/builds/35566/steps/install-port/logs/stdio, now the build just can't find libc++

[kencu (Ken)]

the root cause of this is having a libc++.dylib with @rpath/libc++.1.dylib being found opportunistically in the llvm library directory.

The libc++ stuff in the clang ports needs to be moved to a subdirectory where it won’t be opportunistically found when linking in the llvm libraries.

[kencu (Ken)]

same deal as #69725

[wyuenho (Jimmy Yuen Ho Wong)]

Seems to have been fixed by ​https://github.com/macports/macports-ports/commit/c2a9a478a262558685907b6addbf3b538a084edc
