Thank you


Cross compilation works in general -- our CI testing setup

includes various cross-compile configurations, including

building Windows executables from a Linux host

(eg https://gitlab.com/qemu-project/qemu/-/jobs/1042844159).


You'll need to be more specific about exactly what you're

trying to do and failing (eg quoting exact commands,

setups, error messages).



-- PMM

A simple example ./configure --enable-sdl --enable-sdl-image --enable-gtk --target-list=x86_64-softmmu --cross-prefix=x86_64-w64-mingw32-
