How to build and use GDB

Ubuntu uses quite an old version of GDB. When I need to use an updated version of GDB, here is what I do:

• Obtain the newer version of GDB by downloading its .tar.gz from here. Unzip it.
• Configure and build it:

$ ./configure
$ make

• The newly built GDB executable can be found at gdb/gdb in your current directory. You can copy it or invoke it directly to use it.

Tried with: GDB 8.1 and Ubuntu 16.04
