go build Windows version from Linux

[GrandeTartarie]

Some info:

go version go1.17.2 linux/amd64
Windows 10 Pro 21H1 19043.1200

Use this to build:

CGO_ENABLED=1 GOOS=windows CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ go build -ldflags "-s -w -H=windowsgui -extldflags=-static" -p 4 -v ./cmd/app

Got binary:

Try to run:

But nothing is happened when I've tried to run it. Nothing

From CMD:

The same binary for Linux is two times bigger(15MB) than .exe

Seems like OpenGL required. I've skipped it earlier. Does anyone know about native gui lib to make UI apps?

[AllenDang]

Nop, there is no cross-platform GUI lib to create native gui for golang, not even Qt.

[AllenDang]

And I don't think there will be one in future. Qt and Flutter also use their own drawing engine to create UI. Native is very complex and hard to maintain.

If you have a VM with no OpenGL support, install this:

the "mesa3d-xxxx-release-msvc.7z" allways worked to me.
I was struggling trying to make GUI programs in Go because I use a lot of Hyper-V and XenServer VMs, and both of them are limited to OpenGL 1.1 I believe. That driver allows to run OpenGL 3+ software rendered

PS: More info about the Mesa drivers: https://en.wikipedia.org/wiki/Mesa_(computer_graphics)

@GrandeTartarie any updates here?
Last days I was fighting with this cross-platform builds and got it working.
