Quick oneliner to export LD_LIBRARY_PATH containing all the pathnames that brings a shared library (.so) file in, so the lazy ones like myself can sometimes risk running/testing software that uses these libraries without issuing a ‘make install’.
There are probably more clever/elegant ways to do that, but whatever:
export LD_LIBRARY_PATH=$(for j in \ $(for i in \ $(find . -name '*.so'); \ do dirname $i; done | sort | uniq);\ do readlink -f $j; done |\ awk '{ printf "%s:", $0 }')
