Avec autotools, je reçois ceci:

jonquil@jonquil-Satellite-L755D:~/Downloads/akonadi-googledata-1.2.0/build/build$ autoreconf -i -f
Can't exec "libtoolize": No such file or directory at /usr/bin/autoreconf line 196.
Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 196.
autoreconf: `configure.ac' or `configure.in' is required

Installez build-essential si vous ne l'avez pas déjà fait. Vous pouvez l'installer dans le centre logiciel ou avec:

sudo apt-get update && sudo apt-get install build-essential

gcc ne contient pas g ++, ce sont des paquets différents. Installez g ++ :

apt-get install g++

Je suis conscient que c'est "Ask Ubuntu", mais si quelqu'un avec Fedora rencontrait ce problème, voici ce qui m'a aidé:

sudo dnf install gcc-c++
