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

Unzip or checkout a version of LibreCAD into a directory. CD into that directory and follow these instructions:

Build makefile and compile LibreCAD

qmake librecad.pro
make

After successful compiling, the executible is generated:

Linux: unix/librecad OS X: LibreCAD.app/Contents/MacOS/LibreCAD

A sample building script for OS/X is included as scripts/build-osx.sh. This script file also generates a 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 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/gcc46, lang/gcc47, lang/gcc48 or lang/gcc49

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 can not currently build LibreCAD.

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".

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

After that 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

Build a makefile in the LibreCAD source folder, $ qmake librecad.pro -r -spec mkspec/macports

If the previous step is successful, you can build LibreCAD by issuing, `$ make -j4'

After a successful build, the generated executible of LibreCAD can be found as LibreCAD.app/Contents/MacOS/LibreCAD.

Alternatively, you may try the building script comes with LibreCAD at scripts/build-osx.sh $ cd scripts/ $ ./build-osx.sh
