Make sure you have the Qt version 4 development packages installed by running the following commands:

Kod: Zaznacz cały

$ sudo apt-get install g++ gcc make git-core libqt4-dev qt4-qmake libqt4-help \
qt4-dev-tools libboost-all-dev libmuparser-dev libfreetype6-dev pkg-config

Albo takim stworem, choć ja preferuję pierwszą metodę.
Alternatively, you make sure you have deb-src lines enabled in your sources.list file, and run,

Kod: Zaznacz cały

$ sudo apt-get build-dep librecad

Note that you will most likely need to run qmake-qt4 instead of just qmake.

Kod: Zaznacz cały

cd LibreCAD
qmake-qt4 librecad.pro
make
