QtwebEngine is not working on Embedded Linux with EGLFS plugin

[jero5000]

Hello,

I'm building Qt from Git (5.5 branch) after this commit. The reason why I'm using the repo instead an official Qt release is because I need a change that is not included in Qt 5.4, neither in Qt 5.4.1 (Fix the build on eLinux)

I modified the Qt source code to:

• Implement a EGLFS plugin to work with Broadcom chip.

• Add fixes to avoid compiling errors with uClibc in QtWebengine.

I have testing QWebEngine with the example: qtwebengine/examples/weben
gine/quicknanobrowser

The user interface is shown on the screen when the application is launched and start to load the web site (http://www.qt.io), but the following trace appears and the application is aborted:

[0126/190037:FATAL:gl_fence_egl.cc(42)] Check failed: value == EGL_SIGNALED_KHR || value == EGL_UNSIGNALED_KHR.

I have reported the issue: https://bugreports.qt.io/browse/QTBUG-44820

Any ideas?
Thanks.
