About LibreCAD

LibreCAD is a 2D CAD drawing tool based on the community edition of QCAD (http://www.qcad.org). LibreCAD has been re-structured, ported to new Qt versions and works natively cross platform between OS X, Windows and Linux.

• Install / Build (or see below)

OS X and Homebrew

Install Homebrew from http://brew.sh/.

gcc --version # you'll need gcc 4.4 or newer. If yours is older:

brew tap homebrew/versions

brew options gcc48

brew install [flags] gcc48

mkdir ~/bin

cd ~/bin

ln -s /usr/local/bin/gcc-4.8 gcc

ln -s /usr/local/bin/g++-4.8 g++

ln -s /usr/local/bin/gcc-ar-4.8 gcc-ar

ln -s /usr/local/bin/gcc-nm-4.8 gcc-nm

ln -s /usr/local/bin/gcc-ranlib-4.8 gcc-ranlib
```bash
source ~/.bashrc
```bash
gcc --version # make sure it's 4.8, as installed and configured in the previous step. if it's not, ~/bin might not be on your path

brew install boost qt

Unzip or checkout a version of LibreCAD into a directory.

cd LibreCAD
./scripts/build-osx.sh

This creates an executable "LibreCAD.app/Contents/MacOS/LibreCAD" and package "LibreCAD.dmg".

OS X and MacPorts

install MacPorts from http://www.macports.org/

You can install LibreCad using MacPorts by: $ sudo port install librecad

You can build LibreCAD manually by following steps:

Install QT and a new gcc, which should have a version 4.4 or later.

Install a version of Qt and boost, for example $ sudo port install gcc46 qt4-creator-mac qt4-mac boost

Select the right compiler, as LibreCAD doesn't build with the default llvm-gcc42, $ sudo port select --set gcc mp-gcc46

Unzip or checkout a version of LibreCAD into a directory.

cd LibreCAD
./scripts/build-osx.sh

This creates an executable "LibreCAD.app/Contents/MacOS/LibreCAD" and package "LibreCAD.dmg".

Users of Ubuntu/Debian and derivatives

Make sure you have the Qt development packages installed. For to install Qt version 4, run the following commands:

$ 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

Alternatively, you make sure you have deb-src lines enabled in your sources.list file, and run,

$ sudo apt-get build-dep librecad

For SVN see also: http://www.librecad.org/2010/10/debian-64-bit-and-ubuntu-compile-how-to/

For git see also: http://librecad.org/cms/home/from-source/linux.html

LibreCAD builds with both Qt4 and Qt5. Note that you will most likely need to run qmake-qt4 or qmake-qt5 instead of just qmake.

After the installation of dependency packages, download the LibreCAD source from the official LibreCAD repository, and run the following commands in the top folder of the downloaded LibreCAD source code:

qmake-qt4 -r
make

as described in section [Generic Unix Users](#Generic Unix Users).

Users of Red Hat and similar distibutions

Install Qt, Boost and muParser development packages for your respective distribution; EPEL and similar repositories may come handy if your base OS does not include the necessary packages.

As an example, for CentOS 6.4, after adding the EPEL repository,

yum groupinstall 'Desktop Platform Development' 'Development tools'

yum install qt-devel boost-devel muParser-devel

will install the necessary build dependencies.

Building of LibreCAD in Red Hat is similar to the building procedure described in the [Ubuntu](#Users of Ubuntu/Debian and derivatives) section.

FreeBSD users

• Building with Qt version5:

• Install

databases/qt5-sql devel/qt5-core devel/qt5-help graphics/qt5-svg math/muparser
net/qt5-network print/qt5-printsupport textproc/clucene-qt5 x11-toolkits/qt5-gui
x11-toolkits/qt5-widgets

• Run

/usr/local/lib/qt5/bin/qmake QMAKE_CXXFLAGS="-I /usr/local/include" QMAKE_LIBS="-L /usr/local/lib" && make

• Building with Qt version 4:

• Install

databases/qt4-sql devel/qt4-corelib devel/qt4-help graphics/qt4-svg math/muparser
net/qt4-network textproc/clucene-qt4 x11-toolkits/qt4-gui

• Run

qmake-qt4 -r && make

The executable is generated at unix/librecad

Windows Users

Building steps are also given at our wiki page:

LibreCAD Installation from Source

A sample build batch file is included as scripts/build-windows.bat. If successful, this building script generates a Windows installer file using NSIS(http://nsis.sourceforge.net/Main_Page).

• Download a copy of Qt SDK, 5.4.1 for example from http://qt-project.org/downloads

• Download boost, from https://sourceforge.net/projects/boost/files/boost/

• unzip into C:\boost, for example C:\boost\1_53_0 (in this directory you will find boost root directory, INSTALL, index, Jamroot etc.. etc).

Start Qt Creator and load LibreCAD.pro, from the build menu select "Build All".

###Windows Building from Command Line### scritps/build-windows.bat batch file for automatic building is supplied. Read Building Windows by command line for more details.

Generic Unix Users

Install necessary dependecy: Qt, boost, muParser (see http://wiki.librecad.org for details).

Unzip or checkout a version of LibreCAD into a directory LibreCAD.

cd LibreCAD

qmake -r librecad.pro

make

The executable is generated at unix/librecad
