21.4 Default Linker Script

The command line always requires a linker script. However, if no linker script is specified in an MPLAB X IDE project, the IDE will use the device linker script file (device.gld) included with the compiler as the default linker script. This device-specific file contains information such as:

• Memory region definitions
• Program, data and debug sections mapping
• Interrupt and alternate interrupt vector table maps
• SFR address equates
• Base addresses for various peripherals

Linker scripts may be found, by default, in:

<install-dir\support\DeviceFamily\gld

where DeviceFamily is the DSC device family, such as dsPIC33F.

To use a custom linker script in your project, simply add that file to the command line or the project in the “Linker Files” folder.
