LibreCAD is a 2D CAD drawing tool based on the community edition of QCAD (www.qcad.org). LibreCAD has been re-structured and ported to Qt version 4 and works natively cross platform between OS X, Windows and Linux. See http://www.librecad.org

We are in the process of building a user manual and wiki:

http://wiki.librecad.org/index.php/Main_Page

If you use macports, see below. If you use brew, or neither one, use this section.

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
source ~/.bashrc
gcc --version # make sure it's 4.8. if it's not, ~/bin might not be on your path

brew install boost muparser 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".

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 version 4.4 or later.

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

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".

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

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

Install Qt, Boost and muParser development packages for your respective distribution; EPEL(https://fedoraproject.org/wiki/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.

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

Make sure you have the following ports installed:

x11-toolkits/qt4-gui devel/qt4-linguist devel/qt4-help-tools graphics/qt4-svg devel/boost-libs math/muparser

LibreCAD requires a C++11-capable compiler to build, Currently this means that one of

lang/gcc47, lang/gcc48, lang/gcc49 or lang/clang33

must be used.

Once these pre-requisites are satisfied, run the provided

scripts/build-freebsd.sh

See the script itself for some more options. Clang 3.3 does not yet work.

Building steps are also given at our wiki page:

http://wiki.librecad.org/index.php/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, 4.8.4 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).

• Download muParser 2.2.2 or later from http://sourceforge.net/projects/muparser/files/muparser/

• Create a directory named "muparser" in C:\

• Unzip muparser_v2_2_2.zip into C:\muparser\

Notes: At this point you will have the following directory structure: C:\muparser\muparser_v2_2_2\ (assuming you are using muparser-2.2.2). If you prefer to keep muParser in other locations, you should specify the directiory location with a custom.pro file in LibreCAD source folder, for example, the following setting is equivalent to the default muparser path in common.pro:

MUPARSER_DIR = /muparser/muparser_v2_2_2

• Start Qt Desktop using "Qt 4.8.4 for Desktop (MinGW)" shortcut.
• In Qt Desktop console, navigate to muParser build directory (C:\muparser\muparser_v2_2_2\build), then type the following command to built muParser library: mingw32-make -fmakefile.mingw

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

Unzip or checkout a version of LibreCAD into a directory.

cd LibreCAD
qmake librecad.pro
make

The executible is generated at "unix/librecad"
