Cannot build Windows platform on a Mac

Bug Report

Problem

I'm running MacOS Big Sur, and the windows platform within electron doesn't build.

What is expected to happen?

I expect a 64 bit windows binary to be built. I know MacOS Catalina and greater can't build 32 bit binaries.

What does actually happen?

I get an error message: bad CPU type in executable

Information

I understand there's a bit of history or dependency to this issue:

• MacOS no longer supports 32-bit executables since Catalina
• Back in 2019 when many tickets on this were opened, wine didn't ship with a 64-bit executable (but it does now)
• This package depends on upstream packages, which depend on upstream packages, and the problem is most likely rooted up there somewhere.

Some concrete information on the issue from upstream:

• Cannot build msi packages on macOS Catalina (10.15) (nsis is fine) electron-userland/electron-builder#5377
• 32-bit rcedit does not work on macOS 10.15 (Catalina) hosts when building Windows targets electron/packager#1055
• macOS Catalina: wine doesn't work electron/node-rcedit#51

A workaround:

A solution that is floated around on most of those issues above is summarised well here:
electron/node-rcedit#51 (comment)

It suggests using brew to install wine, then editing a package called rcedit to rename wine to wine64. In short, there is a way to make this work. The problem with the workaround from a cordova-electron perspective is that the package doesn't actually get installed anywhere coming from cordova-electron, and I can't work out where this rcedit package fits in the schema of things to file a report elsewhere.

Anyway, back to the core of this issue, it seems possible to build win64 binaries from MacOS and so it seems surprising to me that I can't build those binaries when I could on an earlier mac.

So here's this ticket, where I hope cordova-electron can pursue MacOS win64 builds, even if that simply means identifying the upstream packages and having the community advocate with them. I'm happy to play my part if I can determine how it all fits together.

Command or Code

cordova platform add [email protected]
cordova build electron
