6.4.1 Output Files

The compilation driver can produce output files with the following extensions, which are case-sensitive.

Table 6-3. File Names
Extensions Definition
file.hex Executable file
file.elf ELF debug file
file.o Object file (intermediate file)
file.s Assembly code file (intermediate file)
file.i Preprocessed file (intermediate file)
file.p Preprocedure abstraction assembly language file (intermediate file)
file.map Map file

The names of many output files use the same base name as the source file from which they were derived. For example the source file input.c will create an object file called input.o when the -c option is used.

The default output file is a ELF file called a.out, unless you override that name using the -o option.

If you are using MPLAB X IDE to specify options to the compiler, there is typically a project file that is created for each application. The name of this project is used as the base name for project-wide output files, unless otherwise specified by the user. However check the manual for the IDE you are using for more details.

Note: Throughout this manual, the term project name will refer to the name of the project created in the IDE.

The compiler is able to directly produce a number of the output file formats which are used by Microchip development tools.

The default behavior of xc-dsc-gcc is to produce a ELF output. To make changes to the files output or the file names, see section 6.6 Driver Option Descriptions.
