run-time problem with shared lib load

vlyamtse · 07-01-2010, 08:19 AM

Hello,
I have installed '.so' libs into /usr/local/lib but it seems like application still cannot load them even though i have /usr/local/lib
in /etc/ld.so.conf.d/libc.conf
Application works fine if I add path to the '*.so' files into LD_LIBRARY_PATH, so this is load path issue, the system is Ubuntu...
It was my understanding that having shared libs in /etc/ld.so.conf is sufficient for app to find shared libs, do i have to do something else to have /usr/local/lib as default load path?
Thanks,
-V

Hi,

You have to run

Code:

sudo ldconfig

after adding/editing paths to shared libraries

ldconfig. Tried that - doesn't help

Hi,

What happens if you put /usr/local/lib directly in /etc/ld.so.conf before the include statement?
You can run "ldconfig -v" afterwards, to see if it's added.

Some ( very few ) executables are hard coded to look for
their shared libraries in /usr/lib/ only.

Thus an entry to /etc/ld.so.conf may not work.
