Linux applications, tools, services uses libraries to get necceseary functionalities. Libraries provides a lot of functionality to the related applications, tools and services. One library can be used by different applications. This is called dynamic library using or loading.
Shared libraries reside in
/usr/lib . Each library is put into related directories like
gcc or similar. Dynamic libraries generally have extension
.so but there are also some version related numbering.
libvte.so.9 is a dynamic library for
vte which version is
Add Path To ldconfig
Some times the required libraries for the executeable is not located in the standard paths. The default library path is hold in
LD_LIBRARY_PATH environments variable. We should add new path to this variable. In the example we assume that the new library path is
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/foo
ldconfig is located at
/etc/ld.so.conf which content is like below. We will add the library path with
include command. The final content will be like below.
Now we will run the
ldconfig -p command to read configuration file and rebuild the cache.
$ ldconfig -p
