Problem:

While rebuilding my project, I get an error from the link:

ERROR: (1) Cannot open file :  <project_name>_RTECFG.OBJ

Resolution:

The file <project_name>_RTECFG.OBJ contains the settings the user made in the IDE in Project - Properties - Application.

If the user needs to get these settings:

The file is newly generated on a REBUILD ALL, but not on a simple rebuild.

If the users does do not need these settings (any more), the file <project_name>_RTECFG.OBJ has to be deleted from the Project - Build Settings for the EXE file(s) (may be DLL files).

Right-click on the project's EXE on the left site of the project's view and select Build Settings.

Alternatively click on Project - Build Settings and select the project's EXE.

On the Link tab, change the category from General to Advanced.

Users will find the <project_name>_RTECFG.OBJ file in "Link with these OBJs:".

If the user deletes the file here, the linker will no longer report a missing file.

Delete the file only, if the settings mentioned above are not needed.
