LD.SO.CONF(5)             NetBSD File Formats Manual             LD.SO.CONF(5)

NAME
     ld.so.conf -- run-time link-editor configuration file

DESCRIPTION
     The ld.so.conf file specifies additional default directories (beyond the
     standard set, normally ``/usr/lib'').

     On a.out(5) systems, this file is scanned by ldconfig(8) to create the
     hints files used by the run-time linker /usr/libexec/ld.so to locate
     shared libraries.

     On elf(5) systems, this file is scanned directly by the run-time linker
     /usr/libexec/ld.elf_so.

     Lines beginning with `#' are treated as comments and ignored.  Any other
     non-blank lines beginning with `/' are stripped of leading whitespace and
     trailing comments (introduced with `#') together with any preceding
     whitespace, then treated as directories to be scanned for shared
     libraries to add to the hints.

     On elf(5) lines that do not begin with a `/' are parsed as hardware
     dependent per library directives:

     <library> <sysctl> <variable>[,...]:<library>[,...] ...

     If there is no match, the standard action is taken.

FILES
     /etc/ld.so.conf

EXAMPLES
     libm.so.0       machdep.fpu_present     1:libm387.so.0,libm.so.0

     The above line loads both libm387 and libm when the sysctl(3) variable
     fpu_present has the value 1.

HISTORY
     The ld.so.conf file appeared in NetBSD 1.3.  The ELF support for it was
     added in NetBSD 1.5.

BUGS
     Directory names containing the comment character (`#') and/or leading or
     trailing whitespace cannot be included.  (Embedded blanks are allowed,
     however.)
