Getting unknown ld command 8 in Mojave #60

Closed matthewbauer closed 5 years ago

matthewbauer commented 6 years ago

With cctools 895, I get this on one of the bundled binaries:

$ nix run nixpkgs.darwin.cctools -c nm /usr/lib/libxcselect.dylib
nm: object: /usr/lib/libxcselect.dylib malformed object (unknown load command 8)

I wonder if Apple changed something in the Mach-O format?

I can't do anything at the moment as Apple haven't released new sources in ages.

matthewbauer commented 6 years ago

Definitely! Just noticed it and wanted to report it. It actually looks like it's a fairly small change (some added constant?) but best to wait for apple to release the newest version.

It looks like cctools-921 is available now:

and ld64-409.12:

I got the latest version of cctools/ld64 mention by @matthewbauer to compile with some hacky methods: (This is a reposted comment, sorry about that.)

(Still need to up the version in ld64/src/3rd/helper.c)

Also this is still a issue with the as wrapper:

clang -cc1as: error: unknown target triple 'unknown-apple-macosx10.4.0', please use -triple or -arch

Edit: CCTOOLS_CLANG_AS_TARGET_TRIPLE is there for the as issue. aarch64-apple-darwin gets set to unknown-apple I'm guessing, because arm64-apple-darwin works just fine.
