3.1 Introduction

The MPLAB XC32 Assembler (xc32-as) may be used on the host's command-line interface (e.g., cmd.exe) if you need to build projects written only in assembly code. When building C-based projects, the assembler is called by the xc32-gcc compilation driver, which can be integrated into the MPLAB X IDE project manager.

Many of the commonly used assembler options are accessible as controls in the MPLAB X IDE Project Properties dialog. However, for a more advanced option, you may have to specify the option in the “Alternate Settings” field of this dialog. After you build a project in MPLAB X IDE, the output window shows the options passed to the assembler.
