Linking object files to produce an executable

3.6 Linking object files to produce an executable

The linker combines the contents of one or more object files with selected parts of any required object libraries to produce executable images, partially linked object files, or shared object files.

The command for invoking the linker is:

armlink options input-file-list

where:

options
are linker command-line options.
input-file-list
is a space-separated list of objects, libraries, or symbol definitions (symdefs) files.

For example, to link the object file hello_world.o into an executable image hello_world.axf:

armlink -o hello_world.axf hello_world.o

Compatibility of object files

Arm does not guarantee the compatibility of C++ compilation units compiled with different major or minor versions of Arm® Compiler and linked into a single image. Therefore, Arm recommends that you always build your C++ code from source with a single version of the toolchain.
