Hi Lestroso,

It is a somewhat complicated process to compile projects to Emscripten.
In fact, I am currently trying to get one of our own projects to run.
I should probably post an article about how to do this in the near future.

What you are trying to do in your example though is to give a C++ compiler eC code, so of course that doesn't work too well!

The way it starts is by setting up a new 'Emscripten' compiler in the Ecere IDE's Global Settings/Compilers. There you must configure the toolchain and paths with the proper settings so that it uses Emscripten's Clang compiler with the proper options to compile the C code generated by the eC compiler. I will work on an article describing how to do this in the coming weeks.

Also worth being noted, this must be done using a special development branch of the Ecere SDK where we have support for Emscripten.

More on all this to come.

Best regards,

-Jerome

Dear Jerome,

why don't you make an app to convert a "project.epj" to html5 with emscripten?? you could make it easy from everyone...and it sound good...

I thank you a lot jerome again....

best regards,

lestroso :D
