Create go file for “release”

[ravan...@gmail.com]

hello
I want to make a golang file for "release".
This is my command:

go build -o testi.exe -ldflags "-H windowsgui"

my code:

    package main
import (
    "fmt"
    "os"
    //"github.com/chai2010/qml"
    "github.com/go-qml/qml"
)
func main() {
    if err := qml.Run(run); err != nil {
        fmt.Fprintf(os.Stderr, "error: %v\n", err)
        os.Exit(1)
    }
}
func run() error {
    engine := qml.NewEngine()
    engine.On("quit", func() { os.Exit(0) })

    component, err := engine.LoadString("hello.qml", qmlHello)
    if err != nil {
        return err
    }
    window := component.CreateWindow(nil)
    window.Show()
    window.Wait()
    return nil
}
 
const qmlHello = `
import QtQuick 2.2
import QtQuick.Controls 1.1
Rectangle {
    id: page
    width: 320; height: 240
    color: "lightgray"
    Text {
        id: helloText
        text: "Hello world!"
        y: 30
        anchors.horizontalCenter: page.horizontalCenter
        font.pointSize: 24; font.bold: true
    }
}
`

You already asked this here:https://forum.golangbridge.org/t/create-go-file-for-release/1415

and then over here: http://stackoverflow.com/questions/33484300/create-go-file-for-release

What question do you have exactly, which the other people who tried to help haven't answered?

[ravan...@gmail.com]

Why does it give me this error message?

The program can't start because Qt5Cored.dll is missing from your computer.

Try reinstalling the program to fix this problem.

A .dll file is a so-called "dynamically-linked library" which means
to access the functions it exports, the program has to load and link
this library file *at runtime* on the computer it runs.

Hence if the program was deployed on a target computer, and this
library file is not present there, the program won't start.

Since on Windows, the dynamic linker starts to look for a file it was
asked to load and link in the current directory, the easiest way to
ensure your program can run is to ship those DLLs along with your
program (.exe file). That will surely increase the size of the
installation bundle but that's the price to pay for Qt libraries not
being an integral part of the Windows platform.

this means ,runtime should be installed on each system?

This means that whatever external (that is, not linked in statically)
libraries a program you want to deploy uses, must be present on the
target system.

There are several ways to achieve this:

* The necessary libraries might already be a part of the target system.

Say, each Windows installation has user32.dll, system32.dll and
all the other DLLs forming Win32 API.

* The necessary libraries might be installed as a separate package.

This is the case for .NET stack on older Windows (pre-Vista),
Java stack, and C/C++ runtime libraries for various versions of
the Visual C++ compiler for Microsoft.

This way, you either require your users to obtain and install
such libraries or ship the installer of them along with your program.

* The necessary libraries might be shipped directly with your
program as I explained in my original reply.

Please read [1] carefully. Then read [2].

The following command, How was the use?

Libs: -L${libdir} -lQt5Cored

https://groups.google.com/forum/#!topic/go-qml/b49wjhT_6tk

[Adriano Soares]

It's not a command, it's the line you need to edit.

Open the folder C:\Qt\Qt5.3.2\5.3\mingw482_32\lib\pkgconfig\ (change the numbers to your Qt version).
1. Open a .pc file
2. Find the line beginning with Libs:
3. Remove the last d on the line
4. Repeat for all .pc files

[ravan...@gmail.com]

(change the numbers to your Qt version).

version  my Qt = 5.5 , What do I change?

I convert :

Libs: -L${libdir} -lQt5Widgetsd  to Libs: -L${libdir} -lQt5Widgets

Libs: -L${libdir} -lQt5Quickd  to Libs: -L${libdir} -lQt5Quick

Libs: -L${libdir} -lQt5Qmld  to Libs: -L${libdir} -lQt5Qml

Libs: -L${libdir} -lQt5Networkd to Libs: -L${libdir} -lQt5Network

Libs: -L${libdir} -lQt5Guid to Libs: -L${libdir} -lQt5Gui

But The problem is not solved.

 I didn't find my answer. has any one a training film?

Thank you.

What happens if you run that program from a console window?
Does it print anything?

[ravan...@gmail.com]

it doesn't show any things.
But it shows in this dir: F:\workspace

in the cmd , After the command under:

F:\>cd workspace

F:\workspace>go run test.go

the winow is showing.

After the command under::

F:\workspace>go build test.go

the file is built.

But in another folder does not work .

Grab the Sysinternals suite [1] and figure out how to use the "procmon"
program available in it: it's able to capture all "external" activity
of a program regarding it accessing filesystem, registry and network.

Run your compiled executable in "another folder" while monitoring it in
procmon and figure out what file it fails to load.

(Just to make sure: when I say "figure out" I really mean you studying
it and trying to make sense out of its data, not you grabbing the
procmon's log and dumping it here.)

my problem because doesn't have qml file Which was resolved.

But It has a problem in another computer now.

should I install visual c++?

Consider applying the same approach you've used to solve your current
project -- but this time on that another computer.

Please understand that asking vague questions is of little help because
the answer to your question -- as stated -- is "maybe".
Grab depends.exe, look at your executable on that another machine --
is the tool able to find all the relevant DLLs?
Grab procmon.exe, run your executable, see what libraries/files it tries
to load, and fails.

Please just try that. Solving problems is about coming up with
solutions and *trying* them.

[ravan...@gmail.com]

There is no need to "procmon.exe"

If the dll file is not , program gives the following warning:

The program can't start because Qt5Core.dll is missing from your computer.

Try reinstalling the program to fix this problem.

The problem was solved:

start Procmon.exe

C:\ravandi\user>d:

D:\>cd D:\go\sahih

D:\go\sahih>start test.exe

Files and folders required:

dir platforms

dir QtQuick

dir QtQuick.2

libgcc_s_dw2-1.dll

libstdc++-6.dll

libwinpthread-1.dll

main.qml

Qt5Core.dll

Qt5Gui.dll

Qt5Network.dll

Qt5Qml.dll

Qt5Quick.dll

Qt5Widgets.dll

test.exe

Thank you.

Glad you got it sorted.

I think it's the time for you to revisit this whole thread [1] and the
documentation it points at, especially [2] and [3].
