An error has occurred，the emscripten version is 1.39.11.

Can you show the full emcc command line and the full output?

BTW where is make.py coming from? Is that part of your project or part of emscripten? Its unrelated to this issue most likely but I would not advise importing emscripten into an external python script like that.

make.py From my own project.

Interesting that we don't see any output at all from wasm2js... I guess it crashes without printing anything?

Can you please try with the latest emscripten release: 1.39.20. I think there have been a few fixes in wasm2js since 1.39.11.

Also I would advise you to avoid importing emscripten/tools module into your own python script. The internal structures of emscripten's python code are not designed for external consumption and could change at any time. Maybe just use a normal Makefile, or invoke emcc directly using python's subprocess module?

I invoke emcc directly using python's subprocess module .

Strange, it looks like your make.py script is calling emscripten.Building.emcc... is it not?

You're right. This is the code fragment where the error occurred.

==================================================

sbc100 commented 4 years ago

You can probably trade that out for a simple subprocess.check_call(...).

Anyway, that is unrelated to the actual crash. Can you update the emscripten version to .20 and confirm this issue still occurs?

Also, are you really sure you need WASM=0? Obviously we need to make sure that it works but we don't advise using that option unless you really need it.

Johnly1986 commented 4 years ago

In version 1.39.20 api changed ? emscripten.Building.emcc('glue.cpp', args, 'glue.o') AttributeError: 'module' object has no attribute 'Building'

========================================================

I've changed to a building instance. like this : import tools.building as building But there are new mistakes.

That just looks like a warnings. Is there an error too?

Regarding the warnings, did you rebuild all your object files when you did the upgrade?

Yes, it was a warning, but in the end it caused a breakdown. My project is in docker and looking for options to rebuild.
