There is a new pull request by sirikid against master on the void-packages repository https://github.com/sirikid/void-packages update/wxWidgets-3.1.4 https://github.com/void-linux/void-packages/pull/27487 wxWidgets: update to 3.1.4. I think wxWidgets is mistaking Musl for Windows. @Hoshpak have you seen this error? A patch file from https://github.com/void-linux/void-packages/pull/27487.patch is attached
