.Dt LIBMAP.CONF 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm libmap.conf
|
|
.Nd "configuration file for dynamic object dependency mapping"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm libmap
|
|
functionality of
|
|
.Xr ld-elf.so.1 1
|
|
allows dynamic object dependencies to be mapped to arbitrary
|
|
names.
|
|
.Pp
|
|
The configuration file consists of two whitespace separated columns; the
|
|
left hand side containing the mapping candidate and the right hand
|
|
side containing the mapping.
|
|
Dependencies are matched against candidates and replaced with the mappings.
|
|
.Pp
|
|
Constrained mappings may be specified by enclosing the name of the
|
|
executable or library in brackets.
|
|
All mappings following a constraint will only be evaluated for that constraint.
|
|
Currently, constraints
|
|
are matched literally so that an executable with a fully qualified pathname
|
|
will only match the same constraint.
|
|
This means that
|
|
.Pa /usr/bin/foo
|
|
will not match a constraint for
|
|
.Pa foo
|
|
and vise-versa.
|
|
.Pp
|
|
WARNING!
|
|
Constrained mappings must never appear first in the configuration file.
|
|
While there is a way to specify the
|
|
.Dq default
|
|
constraint, its use is not recommended.
|
|
.Pp
|
|
The most common use at the date of writing is for allowing multiple
|
|
.Tn POSIX
|
|
threading libraries to be used on a system without relinking or
|
|
changing symlinks.
