Well Kdevelop and Kdevplatform 4.90.92 build on cygwin.

[Michael George Hart]

For some unknowable I am now getting a dialog with the following message:
      "Now I get the error dialog box:
Could not find any plugins during startup.
Please make sure QT_PLUGIN_PATH is set correctly.
Refer to this article for more information."

To tell the truth, after reading the article and  doing some research via
Google.  setting QT_PLUGIN_PATH does not seem that obvious in the Cygwin
environment.

The source of the shared memory problem can be found in the main.cpp file
kdevelop-5/4.90.92/kdevelop-4.90.92/app/main.cph

See code above is the source of my grief under Cygwin ---Years ago coding
similar to a known kdevelop bug (https://bugs.kde.org/show_bug.cgi?id=249107
)

Intrestingly when I commented out line the lines
"if
(!QProcessEnvironment::systemEnvironment().contains("KDEV_DISABLE_SPLASH"))
{
        splash = new KDevSplashScreen;
        splash->show();
    }"

I started getting the Dialog box; now it always appears even when below
lines of code are uncomment

    KDevSplashScreen* splash = nullptr;
    if
(!QProcessEnvironment::systemEnvironment().contains("KDEV_DISABLE_SPLASH"))
{
        splash = new KDevSplashScreen;
        splash->show();
    }

    if(!Core::initialize(splash, Core::Default, session))
        return 5;


I read KCrash::initialize does no do anything when in debug mode. Where can
I get the source code to this so I may try the latest build under cygwin?

I have tracked down that QXcbShmImage: shmget() failed (88) for size 179960
(409x110) may have something to do with how xserver is started on MS
WINDOWS

Anything you guys want me to try
