4.10 MPLAB X UNIVERSAL TOOLSUITE EQUIVALENTS

When compiling under the MPLAB X IDE, it is still the compiler’s command-line driver

that is being executed and compiling the program. The MPLAB XC8 compiler plugins

controls the MPLAB X IDE Properties dialog that is used to access the compiler

options, however these graphical controls ultimately adjust the command-line options

passed to the command-line driver when compiling. You can see the command-line

options being used when building in MPLAB X IDE in the Output window.

The following dialogs and descriptions identify the mapping between the MPLAB X IDE

dialog controls and command-line options.

If you are using MPLAB IDE v8, see Section 4.9 “MPLAB IDE V8 Universal Tool-

suite Equivalents”.
