Cross-compile Qt5.7, error: features.h: No such file or directory

drewpol

Hello everyone. It's my first post on this forum.

First, I compiled Qt 5.4 for cross compile with RPi from THIS tutorial and everything works fine. I was able to cross-compile simple Qt app and run it of RPi3.

Then I decided to upgrade Qt version for 5.7 and I followed THIS tutorial. Everything went fine.

My problem is when I'm trying to compile simple app with Qt Creator. I set up IDE also with tutorial from second link. And when I'm trying to compile I get error:

 #include <features.h>
                      ^

I also figured out that when I'm trying to compile Qt app with 5.4 version from first tutorial it works fine, but when I change to 5.7 version I get this error.

That are my settings:

Then in kits when I set Qt Rpi 5.4.2 version I can compile app, but when I change to Qt Rpi 5.7 I get error shown above. I think there is something wrong with qmake settings or I path, but I really can't figure out what's wrong.
I hope there are specialists which can help me with this issue.

Thank you so much!

that's because you have to re sync everything with the new version of Qt on your raspberry pi. also you have to run the phyton script to fix the symbolic links again and then to do the rsync.. also if you are using the rpi.. then you have to take everything from them. the image the qt5pi folder and so on...
Also please note that their files are based on this tutorial found on Qt website http://wiki.qt.io/RaspberryPi2EGLFS
