Ubuntu – How to enable Qt Creator 3.2.2 to use GDB

gdbqt-creator

After installing Qt Creator 3.2.2 from source I tried to run my project with Qt Creator's debugger frontend, but instead of starting to debug I got an error from Qt Creator:

The selected build of GDB does not support Python scripting. It cannot be used in Qt Creator.

Does it mean that I have to build GDB from source, selecting python support, to be able to use Qt Creator in Ubuntu?

As explained in this blogpost, default¹ install of GDB in Ubuntu appears to be gdb-minimal. To get a version of GDB usable with Qt Creator, you can just do

sudo apt-get install gdb

which will remove gdb-minimal, install gdb and additionally install libc6-dbg. After this you'll be able to debug your project using QtCreator without getting such errors.

¹_{I'm not sure in what sense it is the default, maybe it's installed with build-essential, or something else...}

Ubuntu – Upgrade from gdb 7.7 to 7.8

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
