The same version used by the circleci target.

Fixes #3558.

This results in:

  • Travis: emscripten changed (1.37.37), boost unchanged (1.57)
  • Circleci: emscripten changed (1.37.37), boost unchanged (1.57)

But it fails on cirlceci.

Should only merge after the release to avoid any potential problem with using the new emscripten (since no nightlies were created with it yet).

Strangely enough this works on circleci, but fails on travis:

Also the build size is different:
Circleci: Emscripten output size: -rw-r--r-- 1 root root 8219233 Feb 13 22:06 soljson.js
Travis: Emscripten output size: -rw-r--r-- 1 root root 8228799 Feb 13 22:58 soljson.js

(And it took 52 minutes longer for Travis 😉)

Should turn those warnings into errors (since not all solc-js test are actually affected by the missing symbols):

@axic what about -s DEMANGLE_SUPPORT=1? looks like on circleci it was build with it? It's super strange - the thing is that I spend some hours on the weekend for that. The really strange thing is that it also builds on my machine, with trzeci/emscripten:sdk-tag-1.37.33-64bit but that version had exactly the same problem on travis, but additionally to that also a bug in the JavaScript optimizer..

Just realized that .travis.yml contains another docker image reference (to 1.35.4) so perhaps some strange shadowing issue. Not sure why we need a docker pull in travis while using another version in the script.

Current Travis: Emscripten output size: -rw-r--r-- 1 root root 7637505 Feb 20 21:47 soljson.js
Current Circleci: Emscripten output size: -rw-r--r-- 1 root root 8255543 Feb 20 22:07 soljson.js
New Travis: Emscripten output size: -rw-r--r-- 1 root root 8264918 Feb 20 22:13 soljson.js

But still Travis fails with unresolved symbols while circleci is happy:

After cleaning the emscripten cache, the new emscripten version fails to build boost on Travis.

Do we still want to include this with 0.4.21?

No, there's no point forcing this. I'd like to have more testing with the new emscripten with nightlies also it has a >10% size increase and probably will need some tuning once it starts working on travis.

The emscripten we use to ship soljson is 1.35.4 was released on 27 Oct 2015. I wonder what is the risk updating it and what is the risk not updating it.

Latest emscripten docker has a newer cmake, so the cmake installation step can be removed.

Travis just abruptly aborts in the middle of the log. The same warnings exists on circle too, but it doesn't abort.

Maybe some kind of out of memory issue?
