Fail to build with wasm #1034
Comments

The post above was ambiguous. The "another error" is this part. I checked the current implementations of timer module. Other platforms follow the latest interface of the Timer class, but it seems that the wasm timer implementation does not follow it? |

Thanks for the additional details. It looks like something got out of sync in the building of timer for wasm. While other platforms use both modTimer.c and a platform specific timer.c, the wasm port merges those into its timer.c. That's not incorrect, but the inconsistency seems to have created a build mixup. I think this is the commit that introduced the problem, specifically with simulators/manifest.json. Unfortunately, my wasm tooling is not set-up, so I can't easily try. Maybe you can? |

After reverting the commit Moddable successfully builds the wasm target! https://twitter.com/meganetaaan/status/1640393426243035136 I believe our next step should be to make |
That makes sense. Thank you for confirming. |
Build environment: Linux (Ubuntu 20.04) and moddable v3.7.0
Target device: wasm
Description
