Closed akien-mga closed 5 years ago

akien-mga commented 5 years ago

Godot version: 3.2 master (f03c1c8d4fcc)

OS/device including version: Mageia 7 x86_64 Emscripten latest (1.38.39) with latest-upstream branch:

$ emcc -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 1.38.39
clang version 9.0.0 (/b/s/w/ir/cache/git/chromium.googlesource.com-external-github.com-llvm-llvm--project 22c4a147a96447b38ce90e59b27c33079f1aa203)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Issue description: After updating emscripten and the latest-upstream branch to get the fix for #30248, and fixing the unrelated issues in #30270, I now get a new linking error that I did not get previously with 1.38.37:

I assume this is an upstream issue.

Steps to reproduce:

akien-mga commented 5 years ago

Should be fixed on latest upstream release: emscripten-core/emscripten#9023.
