Based on that limited information, Gene, I can only offer a couple of
rounds from the shotgun, to try to bring the varmint down:
a) On a ubuntu box, it is /etc/ld.so.conf that we'd update, then run
"sudo ldconfig -v" to update the library cache. Even if you're on a
different distro, the basic workings of ld.so should be rather
similar.
If you've put the .so into /lib or /usr/lib, then just running
ldconfig without adding anything to ld.so.conf will suffice. (OK,
some distros may run ldconfig at boot, but a grep of /etc/rc* does
not show that on mine.)
(I see that Eagle did at first fail to find /lib/libc.so.6 for me.
Just putting a copy in /lib and running ldconfig worked for me,
confirming the shortcut.)
b) If that doesn't suit, then there's another way to skin the cat:
I've not had the problem with Eagle, but Bitscope was similarly
blind when I first installed it. To help it find the needed library
(libborqt-6.9-qt2.3.so in that case), I provided a signpost to the
directory it lives in:
alias bitscope='export LD_LIBRARY_PATH=/usr/lib/bitscope:$LD_LIBRARY_PATH ; \
/opt/bitscope/dso/Dso &'
i.e. Setting the LD_LIBRARY_PATH was a way to make it go. (It is when
the .so has been compiled with LD_LIBRARY_PATH set, that it is also
needed at runtime.)
Hopefully that lets you bring home a pelt.
