I recently installed NAGWare's Fortran 95 compiler,
and it installed its shared libraries into
/usr/local/lib/NAGWare. To get the compiler to work,
I of course needed to use "ldconfig -m". When I rebooted
the system, I found that the ldconfig portion of /etc/rc
does not recurse into subdirectories of /usr/local/lib
(which is probably a Good Thing), so I had to manually
run "ldconfig -m" to add /usr/local/lib/NAGWare.
There appear to be several options:
(1) Upon booting run "ldconfig -m". This could be done
either manually by root or perhaps from rc.local.
(2) Move the NAGWare shared libraries up one directory
into /usr/local/lib. This is simple, but would make
updating third party software more difficult because
of possible stale libraries.
(3) Edit /etc/rc to explicitly include /usr/local/lib/NAGWare
This becomes an annoyance when running mergemaster.
It also isn't a general solution for other third party
software installations.
(4) Tell all users on the system to add the directory to
a LD_LIBRARY_PATH variable.
(5) Add another knob to rc.conf. A possible solution to
the third party software problem introduces the
extra_ldconfig_paths to /etc/rc.conf and apply this
diff to /etc/rc
