Help with Emscripten/Wasm

[DiffrenzyKeymaster]

I’ve setup emscripten on MaxOS Sierra, using emsdk portable.

Modules and programs compile, but when I try to run the apps, I get this error:

Mojotest.html:67 missing function: _ZNSt3__16chrono12steady_clock3nowEv

I’ve put an examle online here:

Can somebody help?

What version of emscripten are you running? I’m on 1.37.9, use ’em++ -v’ to find out.

Use this link to grab installer for 1.37.9, there’s another one around that installs an older version I think…

Thanks! reinstalling worked

For anybody with the same issue:

Got the portable zip (https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz) and ran ( in terminal from the install dir. ):

./emsdk update
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh

Then I see this when running “em++ -v”:

MyMac:emsdk-portable myusername$ em++ -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 1.37.13
clang version 4.0.0 (emscripten 1.37.13 : 1.37.13)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Users/myusername/emsdk-portable/clang/e1.37.13_64bit
INFO:root:(Emscripten: Running sanity checks)

and in env_macos.txt I put:

‘***** EMSCRIPTEN *****

EMSCRIPTEN=${HOME}/emsdk-portable/emscripten/1.37.13
PATH=${HOME}/emsdk-portable:${HOME}/emsdk-portable/clang/e1.37.13_64bit:${HOME}/emsdk-portable/node/4.1.1_64bit/bin:${HOME}/emsdk-portable/emscripten/1.37.13:${PATH}

PATH=${MX2_HOME}\devtools\emsdk-portable;${PATH}

I think I still have the old Emscripten compiler. I will install the new one.

I broke the emscripten I am not a windows wizzard.

I am trying to fix it again by following the instructions from the monkey2 editor (ted) help screen.

[Mark SiblyKeymaster]

Actually, I recommend using the current instructions in the monkey2 manual:

Monkey2 uses the emscripten sdk compilers and tools to build emscripten and wasm apps.

To install the emscripten sdk, please see this page: https://github.com/juj/emsdk/blob/master/README.md.

After installation, you should have em++ 1.37.9 installed. Use ’em++ -v’ to check version.

Emscripten is still kinda in flux and is unlikely to be ‘fun’ to get going for a while yet!

[DiffrenzyKeymaster]

Just to avoid confusion: My post above follows the current instructions from monkey2 manual and does what https://github.com/juj/emsdk/blob/master/README.md. tells me to.

[PakzParticipant]

Where can I find the monkey2 manual? I only see docs on the top of this site.
