-- Configuring incomplete, errors occurred!

Com autotools eu recebo isso:

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

    

Answer 1

Instale build-essential se você não tiver feito isso. Você pode instalá-lo no Centro de Software ou com:

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

    

Answer 2

O gcc não contém g ++, estes são pacotes diferentes. Instale o g ++ :

apt-get install g++
