Emscripten 1.38.21 error: undefined symbol: glDrawBuffer

[RichardBetson]

Howdy Mark,

I get the following error using the latest dev build of Monkey2 and the latest Emscripten ver. 1.38.21. I can get code to compile if I add -s ERROR_ON_UNDEFINED_SYMBOLS=0 to env_linux.txt in the wasm linker options.

Hope it helps.

Console output Ted2go, Linux Mint:
Mx2cc version 1.1.15

How can I reproduce there issue, eg: is there a particular banana I can compile that causes it or is it only your code?

Sorry bud. :) This seems to be a global issue. For example the calculator, simplelight and mojotest bananas fail as described above. Really anything I've tried fails as described above. Adding -s ERROR_ON_UNDEFINED_SYMBOLS=0 as the fix.

[RichardBetson]

I'll try to take a deeper dive on this.

[blitz-research]

Will take a look this weekend - much easier to fix if it's easy to reproduce! I just hate updating everything and then...nothing. glDrawBuffer isn't actually part of GLES2.0, just an extension. Does all your code still work with your fix above?

My code seems fine with the fix. I'll double check today.

[seyhajin]

I guess the problem is solved. This issue could be closed.
