Description
IFC++ or IfcPlusPlus is an open source (MIT license) library for reading and viewing IFC files from the IfcQuery project.
While the library can be used for different purposes, the most useful component is the example viewer, which can be used to compare the performance of other viewers and editors of IFC data, like Blender and FreeCAD, which use IfcOpenShell.
The example viewer uses Qt and the OpenSceneGraph library to convert the implicit geometry in IFC files into explicit geometry on screen.
Installing
IFC++ is provided in source code so it must be compiled before being used. It is developed mostly in Window, so it includes solution files (.snl
) to compile the IfcPlusPlus.dll
library using Visual Studio. However, it can also be compiled for Linux using CMake.
Compiling in Windows
Follow the instructions in the official ifcplusplus repository.
Compiling in Linux
The general instructions are as follows:
- Get the source code of IFC++ from its main repository.
- Gather all dependencies for compiling, including a C++ compiler, CMake, and Make, and the development files for Boost, Qt 5, as well as the OpenSceneGraph (OSG) library for visualization.
- Run
cmake
to generate aMakefile
, then start the compilation by runningmake
. - Install the
ifcplusplus
shared module to the appropriate library path so that it is found by the IFC++ viewer.
Prerequisites
In a Debian/Ubuntu based distribution, getting the required development files is usually simple.
sudo apt install git cmake gcc g++ libboost-all-dev
sudo apt install qt5-qmake qtbase5-dev qttools5-dev libqt5widgets5 libqt5opengl5-dev
sudo apt install libopenscenegraph-3.4-dev
Get the source code of the project and place it in a custom directory to which you have full write access.
git clone https://github.com/ifcquery/ifcplusplus ifcplusplus-source
CMake configuration
It is recommended to perform the configuration and compilation in a specific build directory separate from the source directory.
mkdir -p ifcplusplus-build
cd ifcplusplus-build
cmake ../ifcplusplus-source/
Actual compilation
If there were no error messages during configuration with CMake, a Makefile
should have been created in the build directory, so you can proceed to compile the libraries by running make
.
make -j N
N
is the number of processors that you assign to the compilation process; choose at least one fewer than the total number of CPU cores that you have.
