emacs-app @29.4_1+nativecomp+rsvg+treesitter+xwidgets ld: library 'emutls_w' not found libgccjit.so: error: error invoking gcc driver

[wyuenho (Jimmy Yuen Ho Wong)]

After upgrading to macOS 15.2, Xcode 16.2 and a port migrate, when native compiling some packages on Emacs 29, I get lots of these messages in the *Native-compile-Log* buffer. It appears the trampolines for native compile advices to primitive functions are messed up due to a missing reference to libemutls_w in libgccjit. This problem currently broke native compilation for the emacs packages: lsp-mode, magit, forge, git-modes, multiple-cursors, because they all advise Emacs primitive functions.

I am also experiencing this issue with a fresh macports installation on an M1 MacBook Air.

Same emutls_w and libgccjit.so: error: error invoking gcc driver messages.

I've managed to circumvent the issue on my end for now by putting this in my .emacs:

(setq native-comp-enable-subr-trampolines nil)
