Chapter 6 Using Linker

L path_name

Specify a directory containing library files

Functional description

This option specifies a directory that contains library files.

Library files following the L option specification will be searched for in the specified directory. First, the current directory is searched. And then, the specified directory is searched. When the L option is used multiple times, the search will be performed in the order of definition.

If any library file is not found, the linker outputs an error message to terminate operation.

Rules of use

This option is specified with the hyphen (-) option specification character, followed by the upper-case letter 'L', then either immediately followed by the path name or a space and the path name.

ld103 -L/usr/lib -lsample.lib -sample2.lib prog1.rf prog2.rf

The files sample.lib and sample2.lib will be searched for in the directory /usr/lib.

Default specification

Library files specified by the l option will be read.
