loading shared objects
Dear list,
Maybe it is a bit off topic, but I encountered a dynamic linking problem on my Debian stable system.
A program (KiCad) tries (and fails) to load a library (libngspice.so.0.0.0).
I set LD_DEBUG=libs, and I get this:

I have this in my /etc/ld.so.conf.d/libc.conf:
/usr/local/lib
so it shall find the library. But this is interesting that in the above log, /usr/local/lib is missing. I run ldconfig several times. I also greped ld.so.cache, and there is the library there.
Can you explain me what is going on here?
Thanks,
Levente
