Cross compile Qt application
-
Hi everyone,
I have a desktop computer running Ubuntu with all of the Qt dev tools installed from the repositories. I also have an i.MX6 board running Ubuntu, and I've installed the Qt libraries using the repositories on that board as well.
If I build an application on the i.MX6, there are no problems. What I'd like to do is build the application on my desktop and copy the binary onto the i.MX6. I've created a copy of the i.MX6's filesystem on my desktop so I can link against the libraries, and I've installed arm-linux-gnueabihf-g++ and created a qmake.conf file, but I'm getting errors when trying to build the project:
../../i.MX6/filesystem/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory
#include <bits/predefs.h>
^
compilation terminated.
make: *** [main.o] Error 1Here's the qmake.conf that I'm using:
#qmake configuration for building with arm-linux-gnueabihf-g++

QMAKE_INCDIR = /home/marlon/i.MX6/filesystem/usr/include
QMAKE_LIBDIR = /home/marlon/i.MX6/filesystem/usr/libload(qt_config)
Can anyone help me out with this?
Thanks

Hi, i also encountered the same error sometime back, in fact i encountered many other errors also. Downloading the latest stable version of the QT source code resolved all my issues.
