How to specify non-default shared-library path in GCC Linux Getting error while loading shared libraries when running

Question

There is a laptop on which I have no root privilege  onto the machine I have a library installed using configure --prefix  HOME  usr   after that  I got these files in    usr lib   libXX so 16 0 0 libXX so 16 libXX so libXX la libXX a  when I compile a program that invokes one of function provided by the library with this command   gcc XXX c -o xxx out -L HOME  usr lib -lXX xxx out was generated without warning  but when I run it error like this was thrown    xxx out  error while loading shared libraries  libXX so 16  cannot open shared object file  No such file or directory   though libXX so 16 resides there  my clue-less assumption is that    usr lib wasn t searched when xxx out is invoked  but what can I do to specify path of  so   in order that xxx out can look there for  so file  An addition is when I feed -static to gcc  another error happens like this  undefined reference to  function proviced by the very librar   It seems  so does not matter even though -L and -l are given to gcc  what should I do to build a usable exe with that library   For other people who has the same question as I did I found a useful article at tldp about this  It introduces static shared dynamic loaded library  as well as some example code to use them

Should it be LIBRARY PATH instead of LD LIBRARY PATH   gcc checks for LIBRARY PATH which can be seen with -v option

There are two ways to achieve that    Use -rpath linker option    gcc XXX c -o xxx out -L HOME  usr lib -lXX -Wl -rpath  home user  usr lib   Use LD LIBRARY PATH environment variable - put this line in your    bashrc file   export LD LIBRARY PATH  home user  usr lib   This will work even for a pre-generated binaries  so you can for example download some packages from the debian org  unpack the binaries and shared libraries into your home directory  and launch them without recompiling   For a quick test  you can also do  in bash at least    LD LIBRARY PATH  home user  usr lib   xxx out   which has the advantage of not changing your library path for everything else
