1 year ago can you run with make VERBOSE=1 so that we can see the full emcc link command? (BTW, I strongly recommend switching to Ninja (cmake -G Ninja) which always shows commands that fail).

Please include the following in your bug report:
Version of emscripten/emsdk: emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.38 (9eff02bc816c50ab0e3b70a3bd5b72a8dc2893a2) clang version 17.0.0 (https://github.com/llvm/llvm-project 004bf170c6cbaa049601bcf92f86a9459aec2dc2) Target: wasm32-unknown-emscripten Thread model: posix InstalledDir: /home/elchaschab/emsdk/upstream/bin
Failing command line in full:
Full link command and output with
-vappended: Even for runtime issues it helps a lot if you can include the full link command. Adding-vto the link command will show all of the sub-commands run which can help us diagnose your issue. I tried adding -v to the link command which printed the clang version.The above link command used to work without problems. I tried repopulating a fresh emsdk and a clean build but with the same result.
