To resolve the issue where your program runs correctly in release mode but encounters errors during debugging with TARGET = IAPProgrammer in the .pro file, follow these steps:
-
Check Debug Build Output: Review the build logs for any warnings or errors that appear only during debug builds. These might indicate issues in your code that are masked in release mode.
-
Verify Dependencies: Ensure all dependencies, especially third-party libraries, are correctly included and their paths specified in the .pro file for both debug and release configurations.
-
Adjust Compiler Settings: Check compiler flags ( QMAKE_CFLAGS_DEBUG) and linker settings ( QMAKE_LDFLAGS Debug). Add necessary debugging flags if required.
-
Check Qt Libraries: Confirm that debug versions of Qt libraries are installed and properly referenced in your project.
-
Inspect .pro File Configuration: Review the .pro file for any misconfigurations, such as incorrect build directories or excluded files that might cause issues during debug builds.
-
Debug Build Process: Use qmake –debug or similar commands to generate detailed logs of the build process, helping identify specific errors during linking or compilation.
-
Clean and Rebuild: Perform a clean build to eliminate any cached or residual files causing unexpected errors.
By methodically addressing each potential issue area, you can identify and resolve the cause of the debugging error.
