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 qt4 and works natively cross platform between OSX, 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-4 SDK installed Install the qt4 SDK by executing 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

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 1: On systems like fedora (& Ubuntu??) You might need to run qmake-qt4 instead of just qmake

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, at mimimum you properly need gcc 44

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

When installed run to 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, `$ 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
