I edited this topic to add the solution to this error (fatal error: bcm_host.h: No such file or directory)

to solve this problem just add these lines

INCLUDEPATH += $[QT_SYSROOT]/opt/vc/include

INCLUDEPATH += $[QT_SYSROOT]/opt/vc/include/interface/vcos

INCLUDEPATH += $[QT_SYSROOT]/opt/vc/include/interface/vcos/pthreads

INCLUDEPATH += $[QT_SYSROOT]/opt/vc/include/interface/vmcs_host/linux

to these two files: "qtbase/mkspecs/devices/linux-rasp-pi-g++/qmake.conf"

and:

"qtbase/mkspecs/devices/linux-rasp-pi2-g++/qmake.conf"

after save the files repeat these two steps "configure" and "make"

the refrence is this thread

Different error in the make step http://stackoverflow.com/questions/34685488/qt-5-6-cross-compile-for-raspberry-pi-with-eglfs

QT Serial Port install in cross-compile environment

I am attempting to adapt the instructions linked here: Qt Serial Port to this cross-compile environment. The Qt Serial Port page suggests that Qt Serial Port is included in Qt5, however I cannot seem to find it. Has it been removed? I am running QT 5.4.2. on my host system.

If I have to install Qt Serial Port, then I am not sure how to successfully install it in this cross-compile environment. Can anyone help with this? Thank you!

Prerequisites to run cross compile tools on fresh Ubuntu/Debian x64

To run the tools on a host running Ubuntu / Debian x64, the following libraries are necessary:

$ sudo apt-get install lib32stdc++6 lib32z1 lib32ncurses5

Otherwise, errors like this might occur:

arm-linux-gnueabihf-g++: Command not found

or

arm-linux-gnueabihf-g++: Kommando nicht gefunden

X C Bindings

I had to add the following parameter to the configure command:

-qt-xcb

Otherwise the following error is shown:

The test for linking against libxcb and support libraries failed!
 You might need to install dependency packages, or pass -qt-xcb.
 See src/plugins/platforms/xcb/README.

Illegal instruction

I just set up a fresh Ubuntu 14.04 and RPiZero Raspbian.

I followed this tutorial and everything worked (after using the discussion page fixes) except for the example.

I built the example without errors, deployed it, set up the libraries, etc.

When I run the example on the Pi I simply get "Illegal Instruction". Nothing else.

I turned on logging and don't see the log output anywhere that I can find.

EDIT: I don't know if you just want me to delete this. I found the problem. I was building for the pi2 and trying to run it on the pi zero. Sorry about that. I am new to this stuff. I figured out how to build for pi 1 / zero and now everything works. This is awesome!!!
