Directories Searched by the Link-Editor
All previous examples assume the link-editor
knows where to search for the libraries listed on the
command line. By default, when linking 32-bit objects,
the link-editor knows of only two standard directories in
which to look for libraries, /lib
followed by /usr/lib
. When linking
64-bit objects, only two standard directories are
used, /lib/64
followed by
/usr/lib/64
. All other
directories to be searched must be added to the
link-editor's search path explicitly.
You can change the link-editor search path by using a command line option, or by using an environment variable.
