I follow a bit of that post
[https://forum.nim-lang.org/t/2838#18350](https://forum.nim-lang.org/t/2838#18350)
and other to get start compiling to wasm.
But I'm stock with some error. Anyone tried to compile to wasm recently?
First error is that the compiler is complaining that I don't have 'mach.h'
So I modified the config to include it -I/usr/include
@if emscripten:
...
cpu = "i386"
passC = "-s WASM=1 -s 'BINARYEN_METHOD=\"native-wasm\"' -I/usr/include
-Iemscripten "
...
@end
Run
Now I have a couple of architecture error
Error: execution of an external compiler program
'/emsdk/emscripten/1.38.12/emcc -c -w -s WASM=1 -s
'BINARYEN_METHOD="native-wasm"' -I/usr/include -Iemscripten -O3

I'm guessing that now it use /usr/include instead of emscripten one. But How do
I solve my mach.h not found if I don't do this? Anyone with a idea?
