How do I use ports as runtime dynamic libraries?

[Hex4dec]

I'm porting OpenJDK to Emscripten, and as Java programs can call natives with runtime dynamic linking, it would be nice to get some libraries like Regal, GLFW, and so on and so forth working.

Is cloning the ports I require and then building them as side modules the only approach? Is there some magic I can do with --use-port?

I've tried emcc -sSIDE_MODULE --use-port=regal null.c -o out/regal.wasm where null.c is an empty C source file. That doesn't work when linked to with dlopen().

Seems like emcc -sSIDE_MODULE=1 .../emsdk/upstream/emscripten/cache/sysroot/lib/wasm32-emscripten/pic/libregal.a -o regal.wasm works. Good enough!

You should be able to do -lregal instead of .../emsdk/upstream/emscripten/cache/sysroot/lib/wasm32-emscripten/pic/libregal.a
