Use embind with --embind-emit-tsd returns error: undefined symbol: _embind_register_class_property #19933

Closed DreamOfIce closed 1 year ago

DreamOfIce commented 1 year ago

When I used 3.1.44 to generate a new function of dts for embind, an error occurred. I have tried to delete the local cache.

Version of emscripten/emsdk:

root@server:/work/fastText.wasm# emcc -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.44 (bec42dac7873903d09d713963e34020c22a8bd2d)
clang version 17.0.0 (https://github.com/llvm/llvm-project a8cbd27d1f238e104a5d5ca345d93bc1f4d4ab1f)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: /root/emsdk/upstream/bin

BTW, I didn't find this symbol in the symbol list json

sbc100 commented 1 year ago

Looks like this was fixed in #19875. This change will be available in 3.1.45, or you can using emsdk install tot to try it out today.

sbc100 commented 1 year ago

Hopefully that answers your question and we can close this issue?

DreamOfIce commented 1 year ago

This problem is solved by using the tot version build, but the generated dts are empty.

Let's discuss this problem in another issue later.
