Linker Tasks

Using Linker commands

The x argument corresponds to the identifying portion of the library path name — the part following lib and preceding the suffix .a or .sl. For example, for the libm.sl or libm.a library, x is the letter m:

$ cc -Aa mathprog.c -lm

The linker searches libraries in the order in which they are specified on the command line (that is, the link order). In addition, libraries specified with -lare searched before the libraries that the compiler links by default.

Using the -l: option

The -l:option works just like the -loption with one major difference:

-l:allows you to specify the full basename of the library to link with. For instance, -l:libm.acauses the linker to link with the archive library /usr/lib/libm.a, regardless of whether -a shared was specified previously on the linker command line.

The advantage of using this option is that it allows you to specify an archive or shared library explicitly without having to change the state of the -aoption. (See also “Caution When Mixing Shared and Archive Libraries” on page 164.)

For instance, suppose you use the LDOPTS environment variable (see “Passing Linker Options with LDOPTS”) to set the -aoption that you want to use by default when linking. And depending on what environment you are building an application for, you might set LDOPTS to -a archive or -a shared. You can use -l:to ensure that the linker will always link with a particular library regardless of the setting of the -aoption in the LDOPTS variable.

Example Using -l:

For example, even if LDOPTS were set to -a shared, the following command would link with the archive libfoo.a in the directory /usr/mylibs, the archive libm.a and libc.a:

$ ld /opt/langtools/lib/crt0.o -u main prog.o -L/usr/mylibs \ -l:libfoo.a -l:libc.a -l:libm.a
