Undefined/duplicate libc++ symbols when linking 2 libraries together #19742

Open susoferreira opened 1 year ago

What im doing

Im trying to compile 2 libraries libsokol and libemu to wasm using entry.c (just a wrapper in c to call the real main, inside libemu), i get undefined symbol error for libc++ symbols, but libc++ is being linked if i understand the debug output correctly? i also tried adding -lc++ and EMCC_FORCE_STDLIBS=1 to the command, giving the same results,however when i add both of those options to the command at the same time i get duplicate symbol errors for those same symbols

Maybe this has something to do with the libraries being compiled from zig? They compiled without errors though

It looks like zig-out/lib/libemu.a was compiled against a different version of libc++ to the one in emscripten. The symbol in zig-out/lib/libemu.a all start with std::__1:: but the symbols in emscripten's libc++ all start with std::__2::? How was libemu.a compiled? It looks like it was not compiled with emscripten.

Yes, they were both compiled with zig (which uses llvm)

zig cc --version
clang version 16.0.1 (https://github.com/ziglang/zig-bootstrap bf1b2cdb83141ad9336eec42160c9fe87f90198d)

Given that zig uses a different version of libc++ I don't see how you can expect to link zip-generated libraries into an emscripten project. Is that supposed to be something supported by zig?

In order to make that work I think the zip build would have to be run against the emscripten sysroot.. but I don't know how zig works. Maybe file a bug with them?
