== Example usage ==<br />
If a library is missing a dependency, it would fail to run due to a missing symbol. What you can do is inject the missing dependency to the library so that when the code is executed, the dynamic loader is able to pull in the necessary library. For example:<br />
{{Highlight<br />
| code = # ldd /usr/lib/x86_64-linux-gnu/liblistSerialsj.so.1.4.0 <br />
linux-vdso.so.1 (0x00007ffcb89cb000)<br />
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5c17a4a000)<br />
/lib64/ld-linux-x86-64.so.2 (0x00007f5c17e88000)<br />
| lang = terminal<br />
}}<br />
We can then inject the missing library in with <code>patchelf</code>:<br />
{{Highlight<br />
| code = # patchelf --add-needed /usr/lib/x86_64-linux-gnu/libserialport.so.0 /usr/lib/x86_64-linux-gnu/liblistSerialsj.so.1.4.0<br />
<br />
# ldd /usr/lib/x86_64-linux-gnu/liblistSerialsj.so.1.4.0 <br />
linux-vdso.so.1 (0x00007ffc4ec8c000)<br />
/usr/lib/x86_64-linux-gnu/libserialport.so.0 (0x00007fccbe15c000)<br />
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fccbdf23000)<br />
/lib64/ld-linux-x86-64.so.2 (0x00007fccbe374000)<br />
| lang = terminal<br />
