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
