Import an Existing MPLAB IDE v8 Project

Use the New Project wizard to import an MPLAB IDE v8 project into an MPLAB X IDE project with the following considerations:

MPLAB IDE v8 workspace settings not transferred

Settings that were saved in a workspace in MPLAB IDE v8 (such as tool settings) will not be transferred to the new MPLAB X IDE project. Refer to the MPLAB IDE v8 help for what is stored in a workspace (MPLAB IDE Reference>Operational Reference>Saved Information).

Project settings, such as compiler, linker, and assembler options, will be transferred to the new MPLAB X IDE project.

MPLAB IDE v8 project possible file changes

An MPLAB IDE v8 project using the “MPLAB C Compiler for PIC24 MCUs and dsPIC DSCs” (aka MPLAB C30) and a COFF debug file format may have changes.

• The MPLAB X IDE project will be converted to the ELF/DWARF debug file format unless the project uses COFF libraries, in which case the project format will continue to be COFF.
• MPLAB IDE v8 is case insensitive to file extensions such as .c and .C. However, MPLAB X IDE is case sensitive and associates .c to C code files and .C to C++ code files. Therefore, if you import an MPLAB IDE v8 project with C code specified as .C, MPLAB X IDE will rename the .C files to .c to avoid incorrect compiler behavior.

MPLAB IDE v8 project possible build changes

An MPLAB IDE v8 project imported into MPLAB X IDE may not build the same as the original project.

• Do not use __FILE__, assert(), __TIME__, or __DATE__ in your project code or the build (and checksum) will be different.
• An MPLAB IDE v8 project that uses logical subfolders will not have the same checksum when imported into MPLAB X IDE. To build with the same checksum, move the files in the logical subfolders into the main logical folder (i.e., Source Files, Header Files, etc.) and then import into MPLAB X IDE.

To remove a logical subfolder under Source Files:

• Drag to files under Source Files.
• Select the folder and hit <Delete>.
• Alternately, you can right click on the folder and select “Remove from Project” to remove the folder from the project. But it exists on the PC, it will not be deleted.
