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?

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

GNU gdb (GDB) 7.8

If you want to uninstall it simply remove gdb from /usr/local/bin/ by executing

sudo rm /usr/local/bin/gdb

Updating GDB from 7.7.1 to 8.2 on Ubuntu 14.04:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get -y --force-yes install gdb

gdb -v

sudo add-apt-repository --remove ppa:ubuntu-toolchain-r/test

sudo apt-get update

The top answer didn't work for me. For some reason I also needed this package to complete the make:

sudo apt-get install texinfo

Then I highly recommend to install this the correct way. I installed the checkinstall utility (which will create a debian package to auto-track all your files generated by make):

sudo apt-get update && sudo apt-get install checkinstall

Now call these 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

sudo checkinstall

Verify that this crated a *.deb file in the current directory (mine was gdb_7.8-1_amd64.deb). So now let's install it the correct way, go ahead and:

1. uninstall gdb quick


2. set the install path of the *.deb
   


3. then install it using apt-get
   

using these respective commands:

sudo dpkg -r gdb

sudo dpkg -i ~/gdb-7.8/gdb_7.8-1_amd64.deb

sudo apt-get install -f

Now you have a properly installed package, and you can remove it using sudo apt-get remove gdb OR sudo dpkg -r gdb. Note that I tested this with gdb 8.0.1, but I assume it should work for any version.
