When I try to import my .mmp-file Carbide.c++ it says:

my.mmp: Cannot create linked resource my.cpp. Linked resources must have a project as their parent.

And my.cpp is one of many .cpp-files in the .mmp-file and it's in the middle of other .cpp-files. My .mmp-file is in group-folder. Here is a snip from .mmp-file:

SOURCE my_path\src\other.cpp
SOURCE my_path\src\my.cpp
SOURCE my_path\src\other2.cpp

Thanks for the help in advance!
