LibreCAD_3

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.

The UI
The kernel
The CADViewer

Compilation Instructions

Required libraries

cairo
Pango
Qt 5
git
liblog4cxx
Google test
Eigen 3
Lua >= 5.2
Curl
Boost
LibDxfRW (see compilation instruction after)

LibDxfRW compilation

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

LibreCAD compilation

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

OSX MacPorts

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 ..

OSX X-Code

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 build. Under some conditions you might want to set a additional search path if libraries are not found, for example if you compile libdxfrw yourself.

![X-Code add headers] (http://skitch.rvantwisk.nl/~rvt/blog/LC.xcodeproj-20150115-143036.jpg)

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?

Ubuntu/Mint

apt-get install qttools5-dev qttools5-dev-tools libqt5opengl5-dev liblua5.2-dev git g++ gcc-4.8 libcairo2-dev liblog4cxx10-dev libpango-1.0-0 libpango1.0-dev libboost-all-dev libqt5svg5 libgtest-dev libeigen3-dev libcurl4-gnutls-dev

You need to compile Google Test in /usr/src/gtest/ and move the libraries in /usr/lib/

###Ubuntu 14.xx GCC version from Ubuntu 14 doesn't support C++14. You need to install GCC 4.9. http://askubuntu.com/a/456849

Windows

###Bash for Windows 10 This is the only way to get LibreCAD running on Windows at the moment.

Follow the instructions for Ubuntu 14.04.
Install Xming or any other X server for Windows
Enter export DISPLAY=:0 before running LibreCAD

###MSYS2

pacman -S mingw-w64-x86_64-cairo mingw-w64-x86_64-pango mingw-w64-x86_64-lua mingw-w64-x86_64-eigen3 mingw-w64-x86_64-apr mingw-w64-x86_64-apr-util mingw-w64-x86_64-qt5 mingw-w64-x86_64-gtest

####Log4CXX:

Use lastest code from repo : git://git.apache.org/log4cxx.git https://issues.apache.org/jira/browse/LOGCXX-463

Put the source in /third_party/apache-log4cxx

./autogen.sh
./configure
make
make install

####LibreCAD:

mkdir build
cd build
cmake -DWINDOWS_MSYS2=ON ..

Create symlinks for .so files with ln -s ../lc*/lib*.so

Replace paths in build/lcUI/path.lua with Windows-style pathes C:\msys64\…

Reading materials for feature usage

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/
