In qtcreator,when i checkout [tools-options-projects-build and run:use jom instead of nmake],it can't launch my program when I click Run!
use jom,it can create the debug and release Directory,the program will create in this path.But use nmake,the program will create in the same directory with source file.So,when i click the run-button,it can't lanuch the program,Because it does not exist in the debug or release directory.
How to to solve the problem?Thanks!
