Linker Tasks

Using Linker commands

the previous example were /apps/lib::xyz, the dynamic loader would search for /apps/lib/libfoo.sl, /usr/local/lib/libfoo.sl, then ./xyz/libfoo.sl.

If the dynamic loader cannot find a required library in any of the directories specified in the path list, it searches for the library in the default location () recorded by the linker.

Moving Libraries After Linking with +s and

SHLIB_PATH

A library can be moved even after an application has been linked with it. Linking the program with +s, enables the program to use the path list defined by the SHLIB_PATH environment variable at run time.

Specifying a Path List with +s and SHLIB_PATH

When a program is linked with +s, the dynamic loader will get the library path list from the SHLIB_PATH environment variable at run time. This is especially useful for application developers who don't know where the libraries will reside at run time. In such cases, they can have the user or an install script set SHLIB_PATH to the correct value.

For More Information:

•“The Path List” provides additional details about the path list to

SHLIB_PATH.

•“Moving Libraries after Linking with +b” provides another way to move libraries.

Passing Linker Options in a file with -c

The -cfile option causes the linker to read command line options from the specified file. This is useful if you have many -hor +e options to include on the ld command line, or if you have to link with numerous object files. For example, suppose you have over a hundred +e options that you need when building a shared library. You could place them in a file named eopts and force the linker to read options from the file as follows:

$ ld -o libmods.sl -b -c eopts mod*.o

$ cat eopts Display the file. +e foo

+e bar
