I have access :-)
shl_load() will load libraries with their complete pathname.
shl_load() Attaches the shared library named by path or the
shared library name that is constructed by using
the path part of path plus the shared library
basename followed by the suffix .0 (e.g.
/usr/lib/libname.0 ) ...
In order to use a dynamic search option, shl_load can be called with
the DYNAMIC_PATH option
DYNAMIC_PATH Allow the loader to
dynamically search for
the library specified
by the path argument.
The directories to be
searched are determined
by the +s and +b
options of the ld
command used when the
program was linked.
Then, for ld:
+b path_list Specify a colon-separated list of directories to
be searched at program run-time to locate shared
libraries needed by the executable output file
that were specified with either the -l or -l:
option. An argument consisting of a single colon
(:) indicates that ld should build the list using
all the directories specified by the -L option and
the LPATH environment variable (see the +s
option).
...
+s Indicates that at run-time, the shared library
loader can use the environment variable SHLIB_PATH
to locate shared libraries needed by the
executable output file that were specified with
either the -l or -l: option. The SHLIB_PATH
environment variable should be set to a colon-
separated list of directories. If both +s and +b
are used, their relative order on the command line
indicates which path list will be searched first
(see the +b option).
These options must however be supplied at link time of the executable.
So it seems to be recommendable to set the DYNAMIC_PATH option in the
shl_load() call. Then later, the application can be linked with +b and/or +s
option to specify the place where to search for the shared libraries.
Best regards,
Lutz
