The fedora 28 distribution is an advanced Linux distribution that includes tools and is supported by the fedora community.
The clear and essential reason for the right development is the learning area.
Here's a great video tutorial about developing fedora packets and that's very useful.
I do not know what it is with this group name the Factory 2.0 devel group , but they are very useful information.

Fedora 28 : GoLang first example .
This tutorial is about GoLang IDE . About this IDE you can read more here - my intro article about this IDE.
I try to used with the platform-native GUI library for Go named andlabs/ui.
First, after you install the IDE you can check the settings on menu Settings: Using this tool with Fedora 28 is easy.
About the first install of andlabs/ui then this come with this error:
The problem come from GoLang IDE settings and andlabs/ui.
I remove and install again the andlabs/ui and now working well.
The result of this source code come with this output:
I try to used with the platform-native GUI library for Go named andlabs/ui.
First, after you install the IDE you can check the settings on menu Settings: Using this tool with Fedora 28 is easy.
About the first install of andlabs/ui then this come with this error:
[mythcat@desk ~]$ go get github.com/andlabs/ui
# pkg-config --cflags gtk+-3.0
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gtk+-3.0', required by 'virtual:world', not found
pkg-config: exit status 1
That tell us is need to install some packages from Fedora repo:
# dnf install gtk3-devel
I used this source code to test the andlabs/ui:package main
import (
"github.com/andlabs/ui"
)
func main() {
err := ui.Main(func() {
input := ui.NewEntry()
button := ui.NewButton("Greet")
greeting := ui.NewLabel("")
box := ui.NewVerticalBox()
box.Append(ui.NewLabel("Enter your name:"), false)
box.Append(input, false)
box.Append(button, false)
box.Append(greeting, false)
window := ui.NewWindow("Hello", 200, 100, false)
window.SetMargined(true)
window.SetChild(box)
button.OnClicked(func(*ui.Button) {
greeting.SetText("Hello, " + input.Text() + "!")
})
window.OnClosing(func(*ui.Window) bool {
ui.Quit()
return true
})
window.Show()
})
if err != nil {
panic(err)
}
}
First time was run well and after I restart the IDE I got this error:
# gui_test
/usr/lib/golang/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
gcc: error: /home/mythcat/go/src/github.com/andlabs/ui/libui_linux_amd64.a: No such file or directory
The problem come from GoLang IDE settings and andlabs/ui.
I remove and install again the andlabs/ui and now working well.
The result of this source code come with this output:
