LibreCAD 3 development (GSoC 2014) This is the new LibreCAD Kernel. With keeping in mind the extensibilty, modularity and the design, the LibreCAD is divided into 3 parts.

1. The UI
2. The kernel
3. The CADViewer

Install cairo
Install Qt 5
Install git
Install liblog4cxx Install pango Install libcurl Install lua Install Eigen3 Install Cmake Install Google test
Install lua Install boost Install g++

git clone --recursive https://github.com/LibreCAD/LibreCAD_3.git

mkdir build
cd build
cmake .. (for a release you would use cmake -DCMAKE_BUILD_TYPE=Release ..)
make -j 4
./lcUI/librecad

If you want to fool around with macports use these build instructions

mkdir build
cd build
/opt/local/bin/cmake -DCMAKE_CXX_COMPILER=/opt/local/bin/g++ -DCMAKE_C_COMPILER=/opt/local/bin/gcc ..
make -j 4
./lcUI/librecad

For a release build you would do:

/opt/local/bin/cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=/opt/local/bin/g++ -DCMAKE_C_COMPILER=/opt/local/bin/gcc ..

MacPorts/brew might not have libdxfrw in it so you need to compile it yourself.

git clone https://github.com/rvt/libdxfrw
cd libdxfrw
mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=Release ..
make
sudo make install

If you like X-Code as your editor you can ask cmake to generate the build file for you.
mkdir xcode
cd build
cmake -G Xcode ..

Then open the project in x-code and buikd. Under some conditions you might want to set a additional search path if libraries are not found, for example if you compile libdxfrw yourself.

When using ports I had to use:

cd /opt/local/include
sudo ln -sf eigen3/Eigen Eigen
sudo ln -sf eigen3/unsupported unsupported

any cmake guru care to comment on this oddity? Is there a way to prevent making that symlink?

If we want to support associative drawings, this is a good introduction to get started http://www.ellenfinkelstein.com/acadblog/understanding-how-dimensions-are-associated-with-objects/
