Description

Describe the bug:

Binaries built on macOS run on Windows 10 Pro, but not on Windows 7 Home Edition Premium.

To Reproduce:

Steps to reproduce the behaviour:

  1. On macOS, copy the First App from https://developer.fyne.io/started/firstapp, procure an image to use as an icon, say someimage.png
  2. Install the XCode CLI development tools with xcode-select --install
  3. Install MinGW with brew install mingw-w64
  4. Build the app with CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc fyne package -os windows -icon someimage.png
  5. Check the binary with file firstapp.exe, it shows PE32+ executable (GUI) x86-64, for MS Windows.
  6. Transfer the binary to a W10 PRo and a W7 machine.
  7. It runs on the former, and is rejected on the latter, with an error about it not being for the proper windows version.
  8. Alternatively, trying to build a 32-bit version with CGO_ENABLED=1 CC=i686-w64-mingw32-gcc fyne package -os windows -icon someimage.png fails with cc1: sorry, unimplemented: 64-bit mode not compiled in.

Device (please complete the following information):

  • OS: Dev: macOS, Target: Windows
  • Version: Dev: both Catalina and Big Sur, Target: Windows 10 Pro, Windows 7 Home Edition Premium
  • Go version: 1.15.8
  • Fyne version: fyne.io/fyne/v2 v2.0.0

Investigate the MinGW version used during cross compilation. Check if the binary links to Windows 10 specific APIs. Consider using older MinGW or setting appropriate flags. Look at issue comments for potential solutions.
