One of such common errors which I often see while installing a program from its source code is error while loading shared libraries. The full error generally looks like this: The reason behind this error is that the libraries of the program have been installed in a place where dynamic linker cannot find it.
Can a static library be linked to a shared library?
First, during compile time, the linker verifies that all the symbols (again, functions, variables and the like) required by the program, are either linked into the program, or in one of its shared libraries. However, the object files from the dynamic library are not inserted into the executable file.
cannot open shared object file: No such file or directory. The reason behind this error is that the libraries of the program have been installed in a place where dynamic linker cannot find it. Fix ‘cannot open shared object file: No such file or directory’ error
How are shared libraries linked into a program?
Shared libraries (also called dynamic libraries) are linked into the program in two stages. First, during compile time, the linker verifies that all the symbols (again, functions, variables and the like) required by the program,
While what I write below is true as a general answer about shared libraries, I think the most frequent cause of these sorts of message is because you’ve installed a package, but not installed the “-dev” version of that package. Well, it’s not lying – there is no libpthread_rt.so.1 in that listing.
Why is my library not loading in Linux?
If you are running your application on UNIX, the path to your dynamic libraries (.so) need to be defined in the LD_LIBRARY_PATH environment variable. The error occurs as the system cannot refer to the library file mentioned.
How to cache a shared library in Linux?
As AbiusX pointed out: If you have just now installed the library, you may simply need to run ldconfig. ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib).
Where does ldconfig look in the lib directory?
By default, ldconfig looks in /lib, /usr/lib, and directories listed in /etc/ld.so.conf and $LD_LIBRARY_PATH. If your library is somewhere else, you can either add the directory on its own line in /etc/ld.so.conf, append the library’s path to $LD_LIBRARY_PATH, or move the library into /usr/lib.
Is there such a thing as a shared library?
Libraries exist – Unix & Linux Stack Exchange Error while loading shared libraries: libdl.so.2 (and others), no such file. Libraries exist Attempting to install a Java application from a .bin file.

Why is RedHat Enterprise missing libdl.so.2 library?
Redhat Enterprise V3.0 missing libdb.so.2 library (10) Answer: Redhat Enterprise V3.0 installations done by the user might be missing the /usr/lib/libdb.so.2 library file. This prevents Delta from starting. This file is part of the GNOME desktop environment, typically we use the KDE environment.
