This is a bug in rapidjson which was patched in the Arch package. Make sure to update your packages and try building Cemu again.

[wantija]

that seems to have fixed it, thanks!

For reference as this issue was the first thing that came up when I googled for this "assignment of read-only member" issue - it is tracked in the rapidjson project under Tencent/rapidjson#2277 . It seems a fix has been merged as of 2016(!) but there has still not been a new release with the fix in it...

thanks for showing me this repo

It's funny that Dev refused to release new version. Instead, he suggested forking the project

.maybe we should find an alternative that has the same release version in all distro instead of custom patches
