There are already two quite interesting blog posts about using Qt Creator on MAC and on Windows, so I will not repeat the basics, as they are there. Both use qbs, but I managed to use CMake.
Instead I'll add some tips on the stuff that I needed to solve in order to make this happen on current Debian Sid.
- The required toolchain is already in Debian, just install binutils-arm-none-eabi, gcc-arm-none-eabi and gdb-arm-none-eabi.
- You will not find arm-none-eabi-gdb-py on the gdb-arm-none-eabi package. Fear not, the provided gdb binary is compiled against python so it will work.
- To enable proper debugging be sure to follow this flag setup. If you are using CMake like in this example be sure to modify CMake/toolchain_gcc.cmake as necessary.
- In Qt Creator you might find that, while try to run or debug your app, you are greated with a message box that says "Cannot debug: Local executable is not set." Just go to Projects →Run and change "Run configuration" until you get a valid path (ie, a path to the .elf or .out file) in the "Executable" field.
