[Gambas-user] Strange problem with running Shell on Fedora (code works in IDE but not in executable!!)

[Willy Raets]

I have this strange problem on Fedora.
I have this form (part of a bigger project) that is used to install rpm
packages on Fedora using yum.
The form has:
txbPass (TextBox) to enter password
tarOutput (TextArea) to output stream read from the running yum in shell
btnInstall (Button) to click to start installing
variable PathTemp (String) contains full path to rpm install file 

The code for btnInstall is: 

Public Sub btnInstall_Click()

  Dim sPass, sEPass, sCommand, sFull As String
  btnClose.Enabled = False
  tarOutput.Clear
  Me.Refresh
  Wait 0.15
  If tbxPass.Text = Null Then
    Message.Warning("First enter a password")
    btnClose.Enabled = True
    tbxPass.SetFocus
  Else
    sPass = tbxPass.Text
    sEPass = "echo \"" & sPass & "\" | "
    sCommand = "yum install -y " & PathTemp
    sFull = sEPass & "sudo -S " & sCommand
    'TODO: Remove print
    Print sFull
    tarOutput.Text = "Start install..\n\n"
    Wait 0.05
    hProcess1 = Shell sFull For Read As "Process1"
    hProcess1.Wait
    hProcess1.Kill
    Wait 0.05
    tarOutput.Text &= "\nEnd install.."
    btnClose.Enabled = True
    btnInstall.Enabled = False
    btnClose.SetFocus
  Endif
  
  Catch
    tarOutput.Text &= Error.Text
    If hProcess1.State = 1 Then
      hProcess1.Kill
    Endif
    Error.Clear

End

Public Sub Process1_Read()

  Dim sLine As String
  Read #hProcess1, sLine, Lof(hProcess1)
  tarOutput.Text &= sLine
  tarOutput.Refresh
  Wait 0.02
  
End 

What happens:
1. When running from IDE (debug -> run) the installation runs perfectly
and application installs.
tarOutput reads:
Start install..

<multiple lines of installation progress output by yum>

End install..


2. When running a gambas executable of the application or install a IDE
made package of the application the installation doesn't run for some
reason and rpm package doesn't install
tarOutput reads:
Start install..


End install..

So no output from the Process1_Read event is added, nor is application
installed. It seems as if shell is never run!!

Any ideas here?
