Go with GTK cross-compile to windows from linux28.02.25

First install docker on your desktop (obviously I recommend you be on a linux distribution).

Now get and enter in fedora container with this command:

sudo docker run -it fedora /bin/bash

Install the mingw packages:

yum install mingw64-gtk3 go glib2-devel

If you are going to download your program through wget do this:

`dnf install wget`

To fix some errors in pkg setup:

bash -c "sed -i -e 's/-Wl,-luuid/-luuid/g' /usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig/gdk-3.0.pc"

cd root
mkdir go
cd go
mkdir src pkg bin
cd src

Now you can configure git in this container to clone your repo or move or otherwise download it.
    cd to your program.
    Setup PKG and Gotk3, this will take about 8 minutes.

PKG_CONFIG_PATH=/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go install -v github.com/gotk3/gotk3/gtk`

Finally compile:

CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc GOOS=windows GOARCH=amd64 go build -ldflags -H=windowsgui

If you do need a CMD, remove the flag -ldflags -H=windowsgui

Copy GTK Libs to your program.

yes | cp -r /usr/x86_64-w64-mingw32/sys-root/mingw/* .

Change to other shell
    Get image id from current container

sudo docker ps -alq

Copy your program from container to your machine.

sudo docker cp <replace-with-your-image-id>:/root/go/src/path-to-your-program/ Destination-to-copy/
