Failed to cross compile Qt 5.6 on RPi 2 (fatal error: bcm_host.h: No such file or directory)

Question

I tried to cross compile Qt 5.6 for RPi 2 by following the tutorial RaspberryPi2EGLFS, but I got this error:

qeglfsbrcmintegration.cpp:35:22: fatal error: bcm_host.h: No such file or directory
 #include <bcm_host.h>
                      ^
compilation terminated.

What's wrong ?

Answer 1

The error clearly states that the problem is that the compiler is missing bcm_host.h. You should be able to fix this by installing libraspberrypi-dev.

The command below should fix it.

sudo apt-get install libraspberrypi-dev
