.\"O creates the necessary links and cache to the most recent shared

.\"O in the file
.\"O .IR /etc/ld.so.conf ,
.\"O and in the trusted directories
.\"O .RI ( /lib

.\"O will attempt to deduce the type of ELF libs (i.e., libc5 or libc6/glibc)
.\"O based on what C libs, if any, the library was linked against.
.\"O .\" The following sentence looks suspect
.\"O .\" (perhaps historical cruft) -- MTK, Jul 2005
.\"O .\" Therefore, when making dynamic libraries,

.\"O Some existing libs do not contain enough information to allow the deduction of
.\"O their type.
.\"O Therefore, the
.\"O .I /etc/ld.so.conf
.\"O file format allows the specification of an expected type.
.\"O This is
.\"O .I only
.\"O used for those ELF libs which we can not work out.
.\"O The format
.\"O is "dirname=TYPE", where TYPE can be libc4, libc5, or libc6.
.\"O (This syntax also works on the command line.)
.\"O Spaces are
.\"O .I not
.\"O allowed.
.\"O Also see the
.\"O .B \-p
