How to compile using emscripten on VS2015 and which compiler have I to use?

Hi !
I tried to compile with emscripten the 3DPrimitiveExample as explained in this document
But I’m not really sure about which compiler I have to use in my case ? ( Windows )
I’ve set the command make reffers to the GNUWin32 Compiler but when I launch

emmake make

I’ve got this answer :
—> make : *** no targets specified and no makefile found. Stop.
Maybe Im not using the correct compiler to solve it ? Am i supposed to use minGW ?
Thanks for your support !

the emscripten version of openFrameworks is not working yet on windows only in linux and osx

Hi Arturo !
It was what i was expecting . nevermind , i will compile it on linux .
Emscripten is great !

Hi there!

Is the emscripten version is still not working in OF now? If its not, then is it possible to be implemented on windows? If its possible then I want to give it a try…


hi Arturo, I have been trying various versions of emscripten on linux (of_v0.11.0_linux64gcc6_release). The latest emscription release 2.04 runs its tests fine within the emscripten folders. However it throws errors when I run “emmake make” in the OF examples.

Looking back to similar issue in Sep 19, it seems ver 1.38.9 was recommended as working at the time

I have also tried installing/activating the ver1.38.9, without success. In this latter case I initially get warnings similar to:
warning: unresolved symbol: _ZNKSt3__212basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEE5rfindEcm
warning: unresolved symbol: _ZNKSt3__212basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEE7compareEmmPKcm

Then an error:
File “/usr/lib/python2.7/”, line 52, in copyfileobj
IOError: [Errno 28] No space left on device

Can you please advise what version of emscripten I should be using, or anything else I can try to troubleshoot the issues?

Thanks and kind regards

From your error it would seem like you are running out of space

Yes, I did check the space. I am running OF and emsdk on a Debian server. I seem to have plenty of space remaining. I am now checking through various other versions of emscripten. This space error is only arising for ver1.38.9.

The last version of emscripten I have tried is ver 1.37.5, and it throws the following error:

I’ll continue check other versions of emscripten. Grateful if anyone can advise whether there is a version that is known and recommended to work with the OF release I have downloaded today from
