Perl not found in PATH. Aborting.



  • I am trying to build a static version of Qt 5.8. My Perl installation is located in C:\Perl64 and the path is also included in my PATH variable: C:\Perl64\bin;C:\Perl64\site\bin;

    But when configure.bat is being run, it gives me an error saying that Perl could not be found: http://i.imgur.com/5ExL8Of.png

    Hi,

    Did you check the content of PATH in that console ?



  • Yes, I tried printing the PATH variable to the console and it did have the Perl path in it: http://i.imgur.com/7NLGCgK.png


  • Lifetime Qt Champion

    Might be a silly question, but is it the same console you used to build Qt ?


  • Moderators

    @Denjas Also I would avoid building in powershell. It has enough differences from a normal cmd to cause issues.

    I don't know if it's causing this problem, but just general info for problems I've run into building Qt before.

    As others suggested verify your path in your console by running set and it should show you all your variables, make sure PATH has your perl in it. Or even easier, just try running perl in that console.



  • The problem that the powershell could not find Perl is in the script line 154. There is a PATH variable which the script sets for the session.

    $env:Path = "$MingwDir\bin;$MingwDir\opt\bin;$env:SystemRoot\system32;$env:SystemRoot"
    

    Just add the perl paths so it looks like this:

    $env:Path = "$MingwDir\bin;$MingwDir\opt\bin;$env:SystemRoot\system32;$env:SystemRoot;C:\Perl\site\bin;C:\Perl\bin"
    

    This powershell script had more issues for me so after a few changes it worked for Qt 5.8.0. I have also changed default paths in script so I do not have to write it every time.

     .SYNOPSIS
    
      Build a static version of Qt for Windows.
    
     .DESCRIPTION
    
      This scripts downloads Qt source code, compiles and installs a static version
      of Qt. It assumes that a prebuilt Qt / MinGW environment is already installed,
      typically in C:\Qt. This prebuilt environment uses shared libraries. It is
      supposed to remain the main development environment for Qt. This script adds
      a static version of the Qt libraries in order to allow the construction of
      standalone and self-sufficient executable.
    
      This script is typically run from the Windows Explorer.
    
      Requirements:
      - Windows PowerShell 3.0 or higher.
      - 7-zip.
    
     .PARAMETER QtSrcUrl
    
      URL of the Qt source file archive.
      By default, use the latest identified version.
    
     .PARAMETER QtStaticDir
    
      Root directory where the static versions of Qt are installed.
      By default, use C:\Qt\Static.
    
     .PARAMETER QtVersion
    
      The Qt version. By default, this script tries to extract the version number
      from the Qt source file name.
    
     .PARAMETER MingwDir
    
      Root directory of the MinGW prebuilt environment. By default, use the version
      which was installed by the prebuilt Qt environment.
    
     .PARAMETER NoPause
    
      Do not wait for the user to press <enter> at end of execution. By default,
      execute a "pause" instruction at the end of execution, which is useful
      when the script was run from Windows Explorer.

    @matobodo I would not use PowerShell to build Qt. CMD.exe is the supported environment.





  • @jsulm No answer to @matobodo after 3 months? Wiki tutorial recommends PowerShell... I'm in the same troubles that @matobodo


  • Moderators

    @jcolominas Since I don't use PowerShell (and mainly develop on Linux) I cannot help here much.


  • Moderators

    @jcolominas I agree with @jsulm . I'm also a linux user, but have built Qt for Windows using both Visual Studio and mingw many many times.

    I have never been successful using powershell though. I always did it with cygwin, msys, or more often than not cmd. Cygwin and msys come with their own set of problems. I usually use one or the other for the awesomeness of bash getting everything set up then shell out to a cmd to build.

    Powershell does things that require powershell knowledge of which I have none. So things that should just work, don't. And if you don't know why you're stuck. It's not that it isn't possible to use powershell it's just that it adds problems and if you aren't good with windows/powershell you may create more headache than it's worth using it over cmd.



  • @matobodo thanks so much, adding explicit Perl path solved the problem. pay attention in the way perl got installed, I had to add: "C:\Strawberry\Perl\site\bin;C:\Strawberry\Perl\bin" in line 154.
