Linking Files Using the Linker with the C-compiler

Outputting OMF Files

Depending upon the options specified by the user, the linker can produce two types of OMF

files:

• Intel Hex Format Executable File

• COFF Format Executable File

USING THE LINKER WITH THE C-COMPILER

The linker is used to link compiled and assembled object files, C-Compiler libraries, user

created libraries and C runtime initialization files. These files are linked according to the

commands that are given in the linker command file. Once the files are linked an executable

file in COFF (.ld) format is produced. The linker can also produce Intel hex (.hex, .dat) files,

map files (.map) and symbol files (.sym) in ZiLOG symbol format.

The primary components of the linker are shown in Figure 3-2.
