Ubuntu – Upgrade from gdb 7.7 to 7.8

gdb

How to upgrade my GDB debugger from the current version which is 7.7 to the next version which is 7.8, Also I'm working on Ubuntu 14.04.1?

Best Answer

gdb 7.8 is currently not available in trusty repo. But you can install it from the source.

Open terminal and type following commands

wget http://ftp.gnu.org/gnu/gdb/gdb-7.8.tar.xz
tar -xf gdb-7.8.tar.xz     
cd gdb-7.8/     
./configure
make
sudo cp gdb/gdb /usr/local/bin/gdb

It will install gdb in /usr/local/bin/ directory. As /usr/local/bin/ is searched before /usr/bin/ whenever a command is executed, running gdb will execute gdb 7.8.

Once installed, you can check gdb version using 

gdb --version

It should output
