8. Open Qt Creator
9. In Option window, click “Build&Run” →“Tool Chains” →“Add” →“GCC”:
To select new tool chain, Change the “Compile path” to “/opt/uClinux/bfin-linux-uclibc/bin/bfin-linux-uclibc-g++”;
Change the “Debugger” to “/opt/uClinux/bfin-linux-uclibc/bin/bfin-linux-uclibc-gdb”.
10. In Option window, click “Build&Run” →“Qt Versions” →“Add”:
In “Add” dialog, navigate the path to /usr/bin. Choose “qmake” and then click “Open”.
Then rename “Version name” to “Qt Embedded for Blackfin”. Click “Apply”.
11.Open a Blackfin project. Click “Project” in the left panel. Under Build Setting, Add build configuration:
Make sure Qt embedded for Blackfin is selected for "Qt version" and BFIN toolchain is selected for "Tool chain".
After the above steps, Qt creator should be successfully configured for uClinux. When you doing program, you can run the program on PC first by using the default configuration, e.g. "Qt 4.8.1" in last picture. After everything is working properly, you can compile the codes using "Qt embedded for Blackfin" configuration for uClinux.
To add libraries or other gcc option, simple edit the Qt project file.
