Compilation problems

fazibear

Hi,

I'm trying to compile Qt 5.12 with latest buildroot, but compilation ends up with such an error:

surface_factory_qt.cpp:(.text._ZN15QtWebEngineCore16SurfaceFactoryQtC2Ev+0x41): undefined reference to `vtable for ui::GLOzoneGLXQt'
collect2: error: ld returned 1 exit status

make: *** [_all] Error 2

I have no idea how I could try to fix this issue. Can anybody have a similar problem?

best regards,
Michał

Same here, but no solution so far. Qt 5.12.4 including QtWebEngine already compiled well on another system (both ubuntu 18.04), so I guess that the environment plays some role here. And I'm compiling with '-no-opengl', which resulted in two other errors in different modules, so I suspect this option is not tested well (QTBUG-76600, QTBUG-76773).

After some more investigating, it seems that just some libraries/dependencies are missing. I have two machines, one compiles Qt with QtWebEngine, one does not. There is a difference in the configuration log:

There are two requirement pages listing necessary packages:

I assume the second link might point into the direction of the problem here.

DerFrank,

Did you manage to find the problem? I am also having the same issue.
