Installed from Source: OBS won't run, fails with plugin and display errors.

[rtroy]

I tried three different scenarios to launch, two from the system console and one from a Windows system connecting in via xwindows. The former looks like a configuration issue because the fundamental issue seems to be a failure to recognize the QT platform plugin "wayland", while the latter looks like an outright bug because the ultmate cause is "malloc(): unsorted double linked list corrupted."

There's no pre-built package for my distribution, Fedora, so I installed from source using the directions found here.

The build seemed to go well, though there were some things I found a little weird about the it - someone more experienced with OBS would probably say they're normal and nothing to worry about. However, these included a significant number of compiler warnings about comparisons made in C code against different kinds of data types - mostly comparing integers of different sizes. Given the double-linked-list error, these could perhaps be caused by just this kind of problem.

When launched from the directly-attached console, from a normal terminal window or from an xterm window, it fails with:

qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, wayland-egl, wayland, xcb.

However, when I run it from a preferred location, using xwindows (X11), I get a different error:

I have the full log of the build and install, if anyone wants to review them.

Thanks for any help.
