Linker Tasks

Using 64-bit Mode Linker Options

Hiding Symbols from export with +hideallsymbols

Use the +hideallsymbols option to hide all symbols to prevent the linker from exporting them in a shared link.

In the following example, main() exports func() and test(). Using +hideallsymbols, the linker does not export these two routines in the a.out.

ld main.o +hideallsymbols -L. -lfoo -lc elfdump -t a.out

a.out:

...

.symtab

index Type Bind Other SectValueSizeName

1 FUNC LOCL 00xb 0x4000000000001104 0test

...

10FUNCLOCL00xb0x40000000000012000func

 

Changing Mapfiles with -k and +nodefaultmap

 

The linker automatically maps sections from input object files onto

 

output segments in executable files. These options to the ld command

 

allow you to change the linker’s default mapping.

 

Use the -kfilename option to provide a memory map. The linker uses

 

the file specified by filename as the output file memory map.

 

The +nodefaultmap option used with -koption prevents the linker

 

from concatenating the default memory map to the map provided by

 

filename. If you specify +nodefaultmap, the linker does not append the

 

default mapfile to your mapfile. If you do not specify +nodefaultmap

 

with -k, the linker appends the output file to the default mapfile.

 

In most cases, the linker produces a correct executable without the use of

NOTE

 

the mapfile option. The mapfile option is an advanced feature of the

 

linker toolset intended for systems programming use, not application

 

programming use. When using the mapfile option, you can create

 

executable files that do not execute.
