Qt error: cannot open output file debug

Question

Today I was debuging my program and suddenly due to power failure, my pc shutdown abnormally. Now when I compile that program, it gives me two errors.

:-1: error: cannot open output file debug\Myprogram.exe: Invalid argument
:-1: error: collect2: ld returned 1 exit status

I cleaned the program, rebuilt it. Ran qmake. Closed the compiler and relaunched to compile program by first running qmake, then debugging but worthless. The program isn't getting compiled. I am a beginner and don't have much knowledge about these problems so bear this question. :). How can i fix it.

Answer 1

Delete entire shadow build directory if you are using shadow build (default build setting is shadow build), then launch QtCreator and try to build.

Answer 2

The debugger has probably put a lock on the file/directory that has not been released due to the power failure. Try to remove the Debug folder or use a tool (like this one) to unlock the directory.

Answer 3

Sometimes exes will be running already. if that is the case You have to go to Application output tab of Qt Creator and close running executables then it will work.
