qeglfsvivintegration.cpp: undefined reference to `fbCreateWindow'

[Lorenc]

I am trying to build qt from sources qt5.10.1 on imx6 development board. I have ubuntu 14.04 on the board and have updated the compiler to gcc 5.6.3

I run the following configure cmd:
./configure -release -opensource -confirm-license -opengl es2 -nomake examples -nomake tests -no-use-gold-linker -recheck -make libs -v
then: #make -j4
I see the following error:

Any help will be greatly appreciated.

@Lorenc Sounds like you have the wrong version of EGL. You need libEGL-fb.so and not the x11 one.
