NAME
ld.so.conf —
run-time link-editor configuration
file
DESCRIPTION
Theld.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.
SEE ALSO
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.)
