Linux Distro Support

Overview

Wails offers Linux support but providing installation instructions for all available distributions is an impossible task. Instead, Wails tries to determine if the packages you need to develop applications are available via your system's package manager. Currently, we support the following package managers:

  • apt
  • dnf
  • emerge
  • eopkg
  • nixpkgs
  • pacman
  • zypper

Adding package names

There may be circumstances where your distro uses one of the supported package managers but the package name is different. For example, you may use an Ubuntu derivative, but the package name for gtk may be different. Wails attempts to find the correct package by iterating through a list of package names. The list of packages are stored in the packagemanager specific file in the v2/internal/system/packagemanager directory. In our example, this would be v2/internal/system/packagemanager/apt.go.

In this file, the list of packages are defined by the Packages() method:

func (a *Apt) Packages() packagemap {
return packagemap{
"libgtk-3": []*Package{
{Name: "libgtk-3-dev", SystemPackage: true, Library: true},
},
"libwebkit": []*Package{
{Name: "libwebkit2gtk-4.0-dev", SystemPackage: true, Library: true},
},
"gcc": []*Package{
{Name: "build-essential", SystemPackage: true},
},
"pkg-config": []*Package{
{Name: "pkg-config", SystemPackage: true},
},
"npm": []*Package{
{Name: "npm", SystemPackage: true},
},
"docker": []*Package{
{Name: "docker.io", SystemPackage: true, Optional: true},
},
}
}

Let's assume that in our linux distro, libgtk-3 is packaged under the name lib-gtk3-dev. We could add support for this by adding the following line:

func (a *Apt) Packages() packagemap {
return packagemap{
"libgtk-3": []*Package{
{Name: "libgtk-3-dev", SystemPackage: true, Library: true},
{Name: "lib-gtk3-dev", SystemPackage: true, Library: true},
},
"libwebkit": []*Package{
{Name: "libwebkit2gtk-4.0-dev", SystemPackage: true, Library: true},
},
"gcc": []*Package{
{Name: "build-essential", SystemPackage: true},
},
"pkg-config": []*Package{
{Name: "pkg-config", SystemPackage: true},
},
"npm": []*Package{
{Name: "npm", SystemPackage: true},
},
"docker": []*Package{
{Name: "docker.io", SystemPackage: true, Optional: true},
},
}
}

Adding new package managers

To add a new package manager, perform the following steps:

  • Create a new file in v2/internal/system/packagemanager called <pm>.go, where <pm> is the name of the package manager.
  • Define a struct that conforms to the package manager interface defined in pm.go:
type PackageManager interface {
Name() string
Packages() packagemap
PackageInstalled(*Package) (bool, error)
PackageAvailable(*Package) (bool, error)
InstallCommand(*Package) string
}
  • Name() should return the name of the package manager
  • Packages() should return a packagemap, that provides candidate filenames for dependencies
  • PackageInstalled() should return true if the given package is installed
  • PackageAvailable() should return true if the given package is not installed but available for installation
  • InstallCommand() should return the exact command to install the given package name

Take a look at the other package managers code to get an idea how this works.

Remember

If you add support for a new package manager, don't forget to also update this page!
