Cross Compile Fyne Applications

ARCHIVED

fyne-cross is now an official Fyne project and has been moved to: https://github.com/fyne-io/fyne-cross

Fyne Cross

fyne-cross is a simple tool to cross compile and create distribution packages for Fyne applications.

It has been inspired by xgo and uses a docker image built on top of the golang-cross image, that includes the MinGW compiler for windows, and an OSX SDK, along with the Fyne requirements.

Supported targets are:

• darwin/amd64
• darwin/386
• freebsd/amd64
• linux/amd64
• linux/386
• linux/arm
• linux/arm64
• windows/amd64
• windows/386
• android
• ios

Note: iOS compilation is supported only on darwin hosts. See fyne README mobile for pre-requisites.

Requirements

• go >= 1.13
• docker
• module-aware mode enabled

Installation

GO111MODULE=on go get github.com/lucor/fyne-cross/v2/cmd/fyne-cross

fyne-cross will be installed in GOPATH/bin, unless GOBIN is set.

Updating docker images

To update to a newer docker image the --pull flag can be specified. If set, fyne-cross will attempt to pull the image required to cross compile the application for the specified target.

For example:

fyne-cross linux --pull

will pull only the fyne-cross:base-latest image required to cross compile for linux target.

Development release

To install a preview of the v2 version or help in testing:

go get github.com/lucor/fyne-cross/v2/cmd/fyne-cross@develop

Usage

fyne-cross <command> [options]

The commands are:

	darwin        Build and package a fyne application for the darwin OS
	linux         Build and package a fyne application for the linux OS
	windows       Build and package a fyne application for the windows OS
	android       Build and package a fyne application for the android OS
	ios           Build and package a fyne application for the iOS OS
	freebsd       Build and package a fyne application for the freebsd OS
	version       Print the fyne-cross version information

Use "fyne-cross <command> -help" for more information about a command.

Wildcards

The arch flag support wildcards in case want to compile against all supported GOARCH for a specified GOOS

Example:

fyne-cross windows -arch=*

is equivalent to

fyne-cross windows -arch=amd64,386

Example

The example below cross compile and package the fyne examples application

git clone https://github.com/fyne-io/examples.git
cd examples

Compile and package the main example app

fyne-cross linux

Note: by default fyne-cross will compile the package into the current dir.

The command above is equivalent to: fyne-cross linux .

Compile and package a particular example app

fyne-cross linux -output bugs ./cmd/bugs

fyne-cross's Issues

[Feature Request] Add option to build release binaries

Go binaries are generally quite large and the only way to make them significantly smaller is to strip out the debugging and dwarf data if you don't want to lose any performance. That is done with -ldflags="-s -w" duing package build time.

I would like an option to just pass something like -release or -strip to build all the resulting cross compiled binaries using that to remove a couple megabytes from each file. If you are sending out a binary to customers, it feels like debug data is unnecessary for most use cases. Those that don't deem it necessary can thus just build without it if they so desire.

Building on Clear Linux fails with add user error

The following error makes it unusable:

adduser: The UID 0 is already in use.
exit status 1

Any help on getting your program to work?

fyne-cross version 1.3.2

Do I have to install MacOSX10.10.sdk?
I just want to build for linux with arm architecture
What should I do? Thank you

Add static build support

See fyne-io/fyne/issues/512

Add support for Go 1.13

Hi! Recently encountered a problem of building an application with a version other than 1.12, so I had to build manually from a target os. Is it possible to add an option to specify which version of go compiler to use?

As I can see docker/golang-cross#39 won't/can't add versions other than 1.12 for OS X - maybe its worth it to add support for new versions to other OS? There is also new version coming soon.

can not pull lucor/fyne-cross:1.3.2

just can pull docker pull lucor/fyne-cross:latest

suggest：update build.go ,const version = "1.3.2"
to :
const version = "latest"

linux/386 does not work with 1.2.x

After upgrading to golang-cross:1.12.2 based on debian buster, cross compiling for linux/386 does not work.

To fix need to create a dedicated 386 docker image.

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

This is believe docker daemon run on local machine, but my docker daemon run in virtualbox and used docker-machine, please read from DOCKER_HOST and connect to docker daemon

Add a flag to build as "console binary" for Windows

fyne-cross build windows binaries as a "GUI binary" passing the -H windowsgui flag to the linker.
It could be useful to have a flag like --console that allows to build as "console binary" for debugging purpose.

MacOS dist packaging should have separate name

Building with the dist packaging support in develop creates the application with a name in the pattern of name-darwin-amd64.app. This is far from practical as nobody would want their distribution binary have *-darwin-amd64 in their name when it shows up in launchpad.

I suggest that a flag is provided -appName that lets the user set the application name in the MacOS packaging. My app would then be called Sparta.app instead of sparta-darwin-amd64.app.

Add support for passing fyne flags

There might be situations where a user wants to compile with specific flags for the fyne toolkit. These flags correspond to the ones listed here.

-ldflags doesn't work in v2

Since v2 of fyne-cross, the -ldflags command line option is not passed to Docker anymore:

Here's the sample program I used to test:

package main

import (
	"fyne.io/fyne/app"
	"fyne.io/fyne/widget"
)

var version string

func main() {
	a := app.New()

	w := a.NewWindow("Hello")
	w.SetContent(widget.NewVBox(
		widget.NewLabel(version),
		widget.NewButton("Quit", func() {
			a.Quit()
		}),
	))

	w.ShowAndRun()
}

With go build -ldflags="-s -w -X main.version=1.2.3", we can see the version number in the label, but the label is empty when building with fyne-cross linux -ldflags "-X main.version=1.2.3"

fyne-cross command

when i use fyne-cross command ,i can not download golang.org/x often.but i have download the package in my local computer.

so i think ,if fyne-cross command can use docker "- v",i can use local gopath by "-v",like:
fyne-cross -v=/home/gopath

then we don’t need to download packages often,Is this method feasible？
thanks

Allow the user to pass the environment variables to the docker?

I cannot access the domain *.golang.org.

How can I tell fyne-cross to pass the environment variables like GOSUMDB and GORPOXY to the docker container?

Add support for passing appID to dist packaging

The fyne package command has support for passing a -appID flag to specify the appID when packaging. this is useful for MacOS and needed for Android builds. Current version of dist packaging in fyne-cross does not support this.

it is so slow when pull

94c7194e2b72: Downloading [======> ] 18.27MB/142.4MB

the layer is so big,

Default binary name should be folder if none is provided

I was building my project using fyne-cross --targets=linux/amd64,windows and the project consists of main.go and assets.go files. Without specifying the name in the command, the built binary is named assets-windows-amd64.exe instead of tic-tac-toe-windows-amd64.exe as I expected. The folder that it resides in is named tic-tac-toe and thus I would think that it would be the name when none other is provided, just like running go build would do.

Package android files as .apk

Right now it seems that the android builds are only .so files and not .apk files. it would be great if this could be achieved to make life easier for people building for android. I for example have no idea on how to install a .so file on an android phone and run the app..

[Feature Request] Ability to package with an icon using fyne/cmd

The cmd for fyne let's users package their applications with a logo to easily have fancy programs with working icons without much hassle, if any at all really. I would love to see a feature here that let's us specify an icon and get packaged versions of all applications (where possible) for all out cross compiled files.

unable to compile

Dist packaged linux binaries seem to include two binaries

Running a dist compile seems to result in two binaries being created, both the name and the regular one. Please see the screenshots below:

Binaries are doubled (leading to huge tar file size):

Desktop files are also double:

Icons too:

I am sorry that I didn't catch this in my earlier testing, I was way too focused on getting my MacOS binary to work 👎

When I try to cross compile to darwin from my windows 10 machine I encounter the following issue:

I am very new to Go and Fyne (and fyne-cross) so I hope it's not just a configuration issue...
Thanks for the app and your time!

Add wildcard support for goarch

In order to compile all supported GOARCH for a specified GOOS we have to specify all combinations.
For example to compile for all supported GOARCH on linux:
--targets=linux/amd64,linux/arm64,linux/386,linux/arm

Adding support for wildcard will make the command more usable in this case:
--targets=linux/*

Add support for FreeBSD

Add Android and iOS support

Initial support for mobile (Android and iOS) has been added into the fyne develop branch (fyne-io/fyne#416) via gomobile. Add support to fyne-cross.

Split docker images per os/arch

Right now we have a unique docker image that supports all os / arch.
Splitting, when possible, into multiple images will allow to reduce download size and time when need to compile only against a subset of os / arch

Introduce a root folder and layout for fyne-cross output

fyne-cross could generates several files and folders when building and packaging fyne apps.
Introducing a unique root folder for fyne-cross should allow to:

• avoid any possible conflict with the existing resources for the project layout we are going to build;
• ignore the fyne-cross resources for a VCS (i.e. adding the root folder to a .gitignore file)

A possible layout could be:

project-root
├── main.go
├── go.mod
├── go.sum
├── ......
├── fyne-cross //fyne-cross root dir
│   └── bin  // will contains the binaries
│   └── dist // will contains the distribution packages
│   └── tmp // will be use to store temporary resources used to build binaries and packages

can not connect net when i use docker images

docker run -t -i lucor/fyne-cross:develop /bin/bash

can not connect net .
just like this can connect network:

docker run -t -i  --net host  lucor/fyne-cross:develop /bin/bash

i can not download any package now,so i want to ask,the docker images can connect network default?

Android build targets failing

Any build target of Android fails with the following error. All 4 arch result in the same error. Windows, Linux, and Darwin are all successful. It seems like the lucor/fyne-cross:android container is missing some required packages.
