Info

Press Finish to finish the set up. After that the project is ready to compile. Click on Project → Build project to compile the project. If you want to set up a remote launch do it like described above with one extra thing. Set this in the field Commands to execute before application: chmod 777 /home/root/Qtcross1;export DISPLAY=:0.0 Important is the additional export command which will tell your application where to find the X server. There are some problems with Eclipse to find the correct include paths and it shows some errors which are no errors, the application will compile just fine but Eclipse will not let you start the application. To solve this you have to disable the Code Analysis in Eclipse. Go to Window → Preferences → C/C++ → Code Analysis. Uncheck all check boxes for the Code Analysis. After that Eclipse may still have some Warnings about not finding some include files. To fix this right click on your Qt project and select Properties. Click on C/C++ Include Paths and Symbols and add these two paths with Add External Include Path: /opt/eldk5.2.1/armv7a/sysroots/armv7avfpneonlinuxgnueabi/usr/include /opt/eldk5.2.1/armv7a/sysroots/armv7avfpneonlinuxgnueabi/usr/include/c++ 18/20

Log in as the user and type $ passwd to change the password. After that open Nautilus on your host machine and click on File → Connect to Server. As Type select SSH, enter the IP address of the DX4 in the field Server and type your user name and password. This should look like the picture below. 19/20
