Install the QT4 development packages, where qtcreator itself is not needed, but it helps to install the whole environment
sudo apt-get install libqwt5-qt4-dev libqwt5-qt4 qtcreator
svn co https://qcanobserver.svn.sourceforge.net/svnroot/qcanobserver qcanobserver cd qcanobserver qmake
After running qmake as above, make a few tweaks in the generated makefile:
In the parameter „INCPATH =“ change
-I/usr/include/qwt5
to
-I/usr/include/qwt-qt4
and in „LIBS =“ change
-lqwt
to
-lqwt-qt4
Then run
make
cd DeviceLib/linux/SocketCAN qmake make cp libSocketCAN.so ../../../lib/
change into the QCANObserver directory and just start the program
./QCanObserver
