Cross-compile gtk crate for Windows

I want to use the gtk crate to write a small gui application for Windows. I was wondering if there is any chance I can cross-compile it from my Linux machine to Windows.

When I try to compile my code against the x86_64-pc-windows-gnu target with PKG_CONFIG_SYSROOT_DIR=/usr/x86_64-w64-mingw32 cargo build --target x86_64-pc-windows-gnu, I get the following error:

error: linking with `x86_64-w64-mingw32-gcc` failed: exit status: 1

This seems like I'm missing the gtk library files for Windows, but I'm not sure what I should do or how I would get those.

Solution

  • I managed to compile it by using this awesome tool.

    Basically it is dockerized Linux Fedora with all necessary dependencies pre-installed.
