Hi guys,

I am hoping one of you can help me. I have a problem loading custom
shared object (.so) files which are not installed on the system (I do
not have root access). Here's the deal:

I've written a C++ program that is configured and built using the GNU
built system. Relevant layout:
root
+ - src
+ - lib
+ - include

In lib and include I have some custom scientific libraries that I
need: lib/custom_lib.so include/custom_header.h

My configure script successfully detects those custom libs, and
builds my program. But I do not know how to run them. On my work I
have fedora, and there I simply set the LD_LIBRARY_PATH environment
variable to point to the lib/ directory, but this does not work at
home (yes, I like to work at home) on Ubuntu. On some other distro's
I have tried it works. This returns empty in Ubuntu:

[1]-$ echo $LD_LIBRARY_PATH

[2]-$

You didn't set the path, at least not in the same session:
~$ export LD_LIBRARY_PATH=somedir
~$ echo $LD_LIBRARY_PATH
somedir
