I tried your dockerfile but I couldn't create docker image

try with

-       cp -r /emsdk_portable/data/.cache/asmjs/ports-builds/sdl2/include/* /extralibs/include/
+       cp -r /emsdk_portable/.data/cache/asmjs/ports-builds/sdl2/include/* /extralibs/include/

Thank you! It worked but I still get some error The OpenTTD repository is the your forked repository I used this command below to compile

sudo docker run -v /home/js/OpenTTD/:/workdir/source -v /home/js/openttd-emscripten-dockerfile/:/workdir/output openttd

but I got this error

make[1]: Leaving directory '/workdir/source/objs/release'
Unknown option --with-libtimidity

[Milek7]

Repository should be on ems_both branch. It might also require increasing starting memory size in final emcc command.

Now I got this error

[SRC] Linking openttd
shared:ERROR: emcc: cannot find library "SDL2"

It might also require increasing starting memory size in final emcc command.

I couldn't get it. I have 2 gb ram and 2 gb swap area. Do I need to create more swap area?

I meant default memory size in final emcc command: e.g. -s TOTAL_MEMORY=33554432 Also I don't know why but on current emscripten it cannot find IDBFS. You can temporarily remove persistent save storage from pre.js (that Module.preRun.push.. function).

You are awesome. Thank you for your help.
