5.6.3 xc32-gcc (32-bit MCU C Compiler)

Although the MPLAB XC32 C Compiler for PIC32A MCU works with MPLAB X IDE, it must be acquired separately. The compiler is available for free to download with minimal optimizations (Free mode). A PRO license may be purchased to unlock full compiler optimizations (PRO mode). See the Microchip compiler webpage (MPLAB® XC Compilers) for details.

A subset of command-line options may be specified in MPLAB X IDE. Select a category and then set up compiler options. For additional options, see the 6.6 Driver Option Descriptions.

See also 5.6.6 Options Page Features.

Note: Some of the compiler options specified by fields in Project Property Categories other than Optimization can affect the size and execution speed of your project. Consider using the Compiler Advisor, accessible via the MPLAB X IDE Tools > Analysis > Compiler Advisor menu item, to compare the size of your project when built with different combination of compiler options.
