Unable to build wasm - Githubissues

Cameron-Evans commented 1 year ago
Hi, I'm unable to get the wasm version to build correctly. It looks like an issue with function definitions. I've removing "EXTRA_" from the build flag and that doesn't change the main issue of the undefined symbols. Any help would be appreciated.
