webassembly advice
Thanks for this repo.
After modifying some code, I can build on Windows and run successfully.
However, I cannot build on webassembly with the following command:
rd /s /q build_wasm emcmake cmake . -B build_wasm -G "Ninja" ninja -C build_wasm -j8
Please give me some advice, how to build this project and let it run on the web?
The compile log is :
ninja -C build_wasm -j 8 ninja: Entering directory build_wasm'
