1
Ensure that your MPLAB® 8.x project is saved from MPLAB 8.14.03A or later.
2
Ensure that all files referenced by an #include directive are included in your project tree. The conversion utility may not add the paths to files not explicitly included in the MPLAB 8 project.
3
Ensure that file names referenced by #include directives are spelled with the proper case (e.g., p24FJ128GA010.h - not p24fj128ga010.h). Non-Windows operating systems are case sensitive.
4
Ensure that relative paths used in #include directives use forward slashes (/) and not back slashes (\). The forward slash is recognized on all supported operating systems while the backslash is only recognized on Windows®. Better still would be to define the paths in the project configuration.
