            Bug ID: 405662
           Summary: Add MSVS 2019 support + fix nits
           Product: Craft
           Version: master
          Platform: MS Windows
                OS: MS Windows
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: Core
          Assignee: vonreth at kde.org
          Reporter: Ross.Boylan at ucsf.edu
                CC: kde-windows at kde.org
  Target Milestone: ---


Please add support for MS Visual Studio 2019, currently available in preview
and RC and scheduled for release April 2

Along the way I encountered some documentation and error handling that I think
can be improved on.

1. Following
https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Windows setup
powershell and start installation.
2. The script asks to choose a compiler and MSVS 2019 is not on the list.
That completes the steps to reproduce.  I pressed on, selecting MSVS 2017,
which is not on my system.

VS2019 was not a choice.
After continuing with 2017 I got the message

Execute: C:\Program Files (x86)\Microsoft Visual
c:\Users\rdboylan\Documents\src\CraftRoot\craft-master\bin\craft.py craft
Please ensure that you have installed the C++ component

and it stopped.


Well, I kind of expected it to fail :)  But it would have been nice if it

I also expected it would be clear whether or not the installation succeeded; it
was not.  That is, the final message sounded as if it could be recommended
post-installation setup.  It was also very unclear what exactly was being
referred to.

Based on looking at the code I'm pretty sure this was a failure.  The likely
immediate cause was that VCTOOLSREDISTDIR was not set.  This was partly because
the instructions noted above do not refer to it until AFTER the instructions to
install craft.  Whether setting it will be sufficient to proceed I don't know;
I'll try as soon as I figure the best way to restart.

In short:
1. Main issue: Add support for VS 2019

Secondary issues:
2. If installation fails, make it clear it has failed.
3. The message "Please ensure that you have installed the C++ component" could
be more explicit about what exactly is missing and how it needs to be
4. Instructions at
should specify steps in the order in which they are performed, i.e., set env
variables before running script.  Better yet, the script could handle this
itself, minimally by warning if a needed environment variable is missing and
maximally by setting it appropriately.  FWIW, I believe with my current
installation C:\Program Files (x86)\Microsoft Visual
Studio\2019\Preview\VC\Redist\MSVC\14.20.27404 is the right value.  I believe
$env:VCTOOLSREDISTDIR= "..." is the right way to set it.

Windows: 10 64 bit; MSVS 2019 Preview

Note the installer did find the Python3.7 that was installed as part of VS.

I was doing this to build kdiff3.
