How to configure qt creator to show C++ code rather than disassembler?

Question

Yesterday I had done a lot of things like updating GCC, Clang and reinstalling Qt Creator.Today when debugging my code step by step, the debugger was showing the disassembley rather than the C++ code I wrote. Pressing F10 or F11, the debugger was moving into assembly code not the .cpp nor .h files I wrote. F11 can only go into the library files but never into the files I wrote.

The arrow appeared in disassembler:

Rather than in main.cpp:

How can I configure Qt Creator such that the debugging arrow tracks each line in the C++ code?

Answer 1

For others who also had this problem but none of the solutions above worked (like me), I found out that the issue for me was simply happening because my project was inside of a directory with special characters (/home/fabio/criação/project) the criação folder seems to have caused the problem. After I changed to /home/fabio/Desktop/project it stop happening.

Answer 2

I ran into a very similar problem debugging code built with the clang toolset in qtcreator, and this answer fixed me up:

gdb doesn't find source files compiled by clang++

You can quickly check if that solution will work for you by navigating to the root of your solution in a shell window and then invoking qtcreator from there...set a break point in main() and try debugging - if it stops and shows source in main.cpp, it's quite likely this is the problem.

If that does work for you, there are probably several better ways to implement the permanent solution suggested by https://stackoverflow.com/users/1632219/rene, but the method that worked for me was to modify my qmake mkspec file for the clang toolset. On my system, it lives in /usr/local/Trolltech/Qt-4.8.5/mkspecs/common/clang.conf, so all I had to do was put a clang invoker script with 'clang++ "$@"' in ~/bin/clang-compile and then set QMAKE_CXX in the mkspec to clang-compile. With that change, when the clang toolset is selected, qmake builds make files that use clang-compile instead of clang++ and then debugging works everywhere.
