Is it possible to build Linux executables on Windows with lxn/walk?

[洪嘉鴻]

Hello everyone:

I use golang with Win10. I want to build GUI executables which can work on Linux.

I found this and I could build GUI executable which can work on Windows.

However, I couldn't build GUI executable which can work on Linux with the followings:

       cd %~dp0

       set GOOS=linux

       set GOARCH=amd64

       go build -v -o gradientcomposite gradientcomposite.go

       pause

      

Is there something wrong with cross-compiler or could "lxn/walk" only work on Windows?

Any help is appreciated.

Thank you very much!

lxn/walk use lxn/win, which wraps windows api,so you can not use it under linux

Any help is appreciated.

Thank you very much!

You could also look into wsl.

The key is to understand go.exe calls go from Windows with a wsl shell.

Also copying wsl env variables to Windows execution.

env GOOS=windows WSLENV=GOOS go.exe build

Alternatively you could maintain two installs of go. Linux/Windows

oops, ignore my last.

I'm not sure there is a "Good" cross platform scenario for GO/html that matches
GOs cross platform abilities, at the moment. Desktop sure but not really, mobile
and desktop at the same time, fyne maybe.

I'm looking at running chrome with --app and and then webview on mobile, both
with a local http server.

There are a few options, but it rather depends on what you need to do.  The most similar to walk for linux would be go-gtk3.  However, for cross-platform, probably the QT bindings.  If you want to go the embedded html route, there are a few different options.  I personally like Wails.  Here is a breakdown of some of the options so that you can research which one fits your needs:

Interesting, though I assume cross compilation is far from what Go offers and
similar to fyne. IOW, it will be painful unless you run multiple virtual
machines/OS and compile natively?

[Philip Chapman]

I do think that yes, you would have to set up some compile environment.  Compiling for Linux from Windows could be possible through an open source/free VM such as VirtualBox or maybe through Window's linux compatibility layer (https://docs.microsoft.com/en-us/windows/wsl/about)  though I am no expert on the latter.  Compiling for OSX is outside of my experience, but I rather doubt that there are proper cross compile options there.  The issue is less with golang or even the CPU, but more so with having the proper dependencies for each OS.  In this case, Fyne may be a better solution than others.  I've not tried it though, so your mileage may vary.

I want to run executables on both Windows and Linux.

I don't think it is convenient to maintain 2 codes with lxn/walk on Windows and go-gtk3 on Linux.

Therefore, I'm trying to look for something that could work on both Windows and Linux.

I'll try the breakdown you offered.

Thank you very much!

Yeah, it gets messy quickly. It can be done, but then you're probably writing another abstraction layer anyway.

 

I started on a hobby project in Fyne today, and combined with fyne-cross I had Linux, macOS and Windows building up and running within minutes. There are some elementary widgets and features (mainly listviews, treeviews and systray stuff) I wish for, but their development process means they'd rather have something working than ship half-done features. That sort of thing makes me think it's the most promising Go GUI/app framework right now.

Excuse me.

Did you mean this?

Thank you very much!

Yes, that's the one, Docs at https://fyne.io and the cross-builder/packager at https://github.com/lucor/fyne-cross. 

[洪嘉鴻]

I see.

I'll try it.

Thank you very much!
