Is it possible to complie this with Emscripten and run in the browser using WASM?

I have basically no experience with compiling programs and gave it a shot with Claude walking me through it but didn't have any luck. Kept getting hung up on an issue removing some part of boost that only works on windows/unix.

However, In theory it seems possible that with WebAssembly we could compile programs like this to run in the browser.

FYI this was the main issue I ran into compiling it:

Update: I created a branch on my fork here with what I've tried so far if anyone wants to jump in and tell me what's going wrong. https://github.com/RayBB/tilemaker/blob/emscripten-support/emscripten_build.md

I have no experience with emscripten but it seems a tall order tbh. Even if you can get past the compilation issues, tilemaker needs lots of working memory - either in RAM or on disk. Running in-browser, I'd guess you'd have less of that? But I'll leave this open in case anyone who knows more than me can advise!

Thanks for the input. I'm interested in using it for small areas like a town or a campus so hopefully wouldn't need too much ram in that case but it's a good question on if less ram is available in the browser.
