Сборка FreeCAD в современных дистрибутивах Линукс, как правило, не вызывает сложностей, поскольку все зависимости можно разрешить с помощью менеджера пакетов, встроенного в дистрибутив. Сборка включает 3 этапа:

  1. Загрузка исходного кода FreeCAD.
  2. Разрешение зависимостей (packages FreeCAD depends upon).
  3. Настройка с помощью "cmake" и компиляция с помощью "make".

Ниже вы найдете подробное описание процесса сборки и особенностей, с которыми можете столкнуться. Если вы найдете ошибки или устаревшие сведения, или если вы используете дистрибутив, которого нет в списке, то мы будем благодарны, если поможете это исправить.

Загрузка исходников

Перед началом сборки вам понадобиться исходный код. Существует 3 способа получить его.


The quickest and best way to get the code is to clone the read-only git repository now hosted on GitHub (you need the git package installed):

git clone https://github.com/FreeCAD/FreeCAD.git free-cad-code

This will place a copy of the latest version of the FreeCAD source code in a new directory called "free-cad-code".


The official FreeCAD repository is on Github: github.com/FreeCAD/FreeCAD

Source package

Alternatively you can download a source package, but they could be already quite old so it's always better to get the latest sources via git or github.

  • Official FreeCAD source packages (distribution-independent): to be advised

Getting the dependencies

To compile FreeCAD under Linux you have to install all libraries mentioned in Third Party Libraries first. Please note that the names and availability of the libraries will depend on your distribution. Note that if you don't use the most recent version of your distribution, some of the packages below might be missing from your repositories. In that case, look in the Older and non-conventional distributions section below.

Skip to Compile FreeCAD

Debian and Ubuntu

On Debian-based systems (Debian, Ubuntu, Mint, etc...) it is quite easy to get all needed dependencies installed. Most of the libraries are available via apt-get or synaptic package manager.

  • build-essential
  • cmake
  • python
  • python-matplotlib
  • libtool


  • libcoin60-dev (Debian Wheezy, Wheezy-backports, Ubuntu 13.04 and before)

  • libsoqt4-dev
  • libxerces-c-dev
  • libboost-dev
  • libboost-filesystem-dev
  • libboost-regex-dev

  • python-dev
  • python-pyside
  • pyside-tools


  • libopencascade-dev (official opencascade version)


  • liboce*-dev (opencascade community edition)

Additional instruction for libcoin80-dev Debian wheezy-backports, unstable, testing, Ubuntu 13.10 and forward

Note that liboce*-dev includes the following libraries:

  • liboce-foundation-dev
  • liboce-modeling-dev
  • liboce-ocaf-dev
  • liboce-visualization-dev
  • liboce-ocaf-lite-dev

You may have to install these packages by individual name.

Optionally you can also install these extra packages:

  • libsimage-dev (to make Coin to support additional image file formats)
  • checkinstall (to register your installed files into your system's package manager, so yo can easily uninstall later)
  • python-pivy (needed for the 2D Drafting module)
  • python-qt4 (needed for the 2D Drafting module)
  • doxygen and libcoin60-doc (if you intend to generate source code documentation)
  • libspnav-dev (for 3Dconnexion devices support like the Space Navigator or Space Pilot)


You need the following packages:

  • gcc-c++ (or possibly another C++ compiler?)
  • cmake
  • doxygen
  • swig
  • gettext
  • dos2unix
  • desktop-file-utils
  • libXmu-devel
  • freeimage-devel
  • mesa-libGLU-devel
  • OCE-devel
  • python
  • python-devel
  • python-pyside-devel
  • pyside-tools
  • boost-devel
  • tbb-devel
  • eigen3-devel
  • qt-devel
  • qt-webkit-devel
  • ode-devel
  • xerces-c
  • xerces-c-devel
  • opencv-devel
  • smesh-devel
  • coin3-devel (if coin2 is the latest available for your version of Fedora, use packages from http://www.zultron.com/rpm-repo/ )
  • soqt-devel
  • freetype
  • freetype-devel

And optionally:


Easiest way to check which packages are needed to compile FreeCAD is to check via portage:

emerge -pv freecad

This should give a nice list of extra packages that you need installed on your system.


You need the following packages:

  • gcc
  • cmake
  • OpenCASCADE-devel
  • libXerces-c-devel
  • python-devel
  • libqt4-devel
  • libshiboken-devel
  • python-pyside-devel
  • python-pyside-tools
  • Coin-devel
  • SoQt-devel
  • boost-devel
  • libode-devel
  • libQtWebKit-devel
  • libeigen3-devel
  • gcc-fortran
  • freetype2
  • freetype2-devel

For FreeCAD 0.14 stable and 0.15 unstable you need to add Eigen3 and swig libraries, that don't seem to be in standard repos. You can get them with a one-click install here:

Also, note that the Eigen3 Library from Factory Education was causing problems sometimes, so use the one from the KDE 4.8 Extra repo

Arch Linux

You will need the following libraries from the official repositories:

  • boost-libs
  • curl
  • hicolor-icon-theme
  • libspnav
  • opencascade
  • python2-pivy
  • python2-matplotlib
  • python2-pyside
  • python2-shiboken
  • qtwebkit
  • shared-mime-info
  • xerces-c
  • boost
  • cmake
  • coin
  • desktop-file-utils
  • eigen
  • gcc-fortran
  • swig
  • xerces-c

Also, make sure to check the AUR for any missing packages that are not on the repositories, currently:

  • python2-pyside-tools

Older and non-conventional distributions

On other distributions, we have very few feedback from users, so it might be harder to find the required packages. Try first locating the required libraries mentioned in Third Party Libraries. Beware that some of them might have a slightly different package name in your distribution (such as name, libname, name-dev, name-devel, etc...).

You also need the GNU gcc compiler version equal or above 3.0.0. g++ is also needed because FreeCAD is completely written in C++. During the compilation some Python scripts get executed. So the Python interpreter has to work properly. To avoid any linker problems during the build process it is also a good idea to have the library paths either in your LD_LIBRARY_PATH variable or in your ld.so.conf file. This is normally already the case in recent distributions.

For more details have also a look to README.Linux in your sources.

Below is additional help for a couple of libraries that might not be present in your distribution repositories

OpenCASCADE community edition (OCE)

OpenCasCade has recently been forked into a Community edition, which is much, much easier to build. FreeCAD can use any version installed on your system, either the "official" edition or the community edition. The OCE website contains detailed build instructions.

OpenCASCADE official version

Note: You are advised to use the OpenCasCade community edition above, which is easier to build, but this one works too. Not all Linux distributions have an official OpenCASCADE package in their repositories. You have to check for yourself if one is available for your distribution. At least from Debian Lenny and Ubuntu Intrepid an official .deb package is provided. For older Debian or Ubuntu releases you may get unofficial packages from here. To build your own private .deb packages follow these steps:

wget http://lyre.mit.edu/~powell/opencascade/opencascade_6.2.0.orig.tar.gz
wget http://lyre.mit.edu/~powell/opencascade/opencascade_6.2.0-7.dsc
wget http://lyre.mit.edu/~powell/opencascade/opencascade_6.2.0-7.diff.gz

dpkg-source -x opencascade_6.2.0-7.dsc

# Install OCC build-deps
sudo apt-get install build-essential devscripts debhelper autoconf automake libtool bison libx11-dev tcl8.4-dev tk8.4-dev libgl1-mesa-dev libglu1-mesa-dev java-gcj-compat-dev libxmu-dev

#Build Opencascade packages. This takes hours and requires 
# at least 8 GB of free disk space
cd opencascade-6.2.0 ; debuild

# Install the resulting library debs
sudo dpkg -i libopencascade6.2-0_6.2.0-7_i386.deb

Alternatively, you can download and compile the latest version from opencascade.org:

Install the package normally, be aware that the installer is a java program that requires the official java runtime edition from Sun (package name: sun-java6-jre), not the open-source java (gij) that is bundled with Ubuntu. Install it if needed:

sudo apt-get remove gij
sudo apt-get install sun-java6-jre

Be careful, if you use gij java with other things like a browser plugin, they won't work anymore. If the installer doesn't work, try:

java -cp path_to_file_setup.jar <-Dtemp.dir=path_to_tmp_directory> run

Once the package is installed, go into the "ros" directory inside the opencascade dir, and do

./configure --with-tcl=/usr/lib/tcl8.4 --with-tk=/usr/lib/tk8.4

Now you can build. Go back to the ros folder and do:


It will take a long time, maybe several hours.

When it is done, just install by doing

sudo make install

The library files will be copied into /usr/local/lib which is fine because there they will be found automatically by any program. Alternatively, you can also do

sudo checkinstall

which will do the same as make install but create an entry in your package management system so you can easily uninstall later. Now clean up the enormous temporary compilation files by doing

make clean

Possible error 1: If you are using OCC version 6.2, it is likely that the compiler will stop right after the beginning of the "make" operation. If it happens, edit the "configure" script, locate the CXXFLAGS="$CXXFLAGS " statement, and replace it by CXXFLAGS="$CXXFLAGS -ffriend-injection -fpermissive". Then do the configure step again.

Possible error 2: Possibly several modules (WOKSH, WOKLibs, TKWOKTcl, TKViewerTest and TKDraw) will complain that they couldn't find the tcl/tk headers. In that case, since the option is not offered in the configure script, you will have to edit manually the makefile of each of those modules: Go into adm/make and into each of the bad modules folders. Edit the Makefile, and locate the lines CSF_TclLibs_INCLUDES = -I/usr/include and CSF_TclTkLibs_INCLUDES = -I/usr/include and add /tcl8.4 and /tk8.4 to it so they read: CSF_TclLibs_INCLUDES = -I/usr/include/tcl8.4 and CSF_TclTkLibs_INCLUDES = -I/usr/include/tk8.4


The SoQt library must be compiled against Qt4, which is the case in most recent distributions. But at the time of writing this article there were only SoQt4 packages for Debian itself available but not for all Ubuntu versions. To get the packages built do the following steps:

wget http://ftp.de.debian.org/debian/pool/main/s/soqt/soqt_1.4.1.orig.tar.gz
wget http://ftp.de.debian.org/debian/pool/main/s/soqt/soqt_1.4.1-6.dsc
wget http://ftp.de.debian.org/debian/pool/main/s/soqt/soqt_1.4.1-6.diff.gz
dpkg-source -x soqt_1.4.1-6.dsc
sudo apt-get install doxygen devscripts fakeroot debhelper libqt3-mt-dev qt3-dev-tools libqt4-opengl-dev
cd soqt-1.4.1
sudo dpkg -i libsoqt4-20_1.4.1-6_i386.deb libsoqt4-dev_1.4.1-6_i386.deb libsoqt-dev-common_1.4.1-6_i386.deb

If you are on a 64bit system, you will probably need to change i386 by amd64.


Pivy is not needed to build FreeCAD or to run it, but it is needed for the 2D Drafting module to work. If you are not going to use that module, you won't need pivy. By November 2015 the obsolete version of Pivy included with FreeCAD source code will no longer compile on many systems, due to its age. If you cannot find Pivy in your distribution's packages repository ort elsewhere, you can compile pivy yourself:

Pivy compilation instructions

Compile FreeCAD

Using cMake

cMake is a newer build system which has the big advantage of being common for different target systems (Linux, Windows, MacOSX, etc). FreeCAD is now using the cMake system as its main building system. Compiling with cMake is usually very simple and happens in 2 steps. In the first step, cMake checks that every needed programs and libraries are present on your system and sets up all that's necessary for the subsequent compilation. You are given a few alternatives detailed below, but FreeCAD comes with sensible defaults. The second step is the compiling itself, which produces the FreeCAD executable. Changing any options for cmake away from their default values, is much easier with cmake-gui or other graphical cmake applications than with cmake on the command line, as the graphical applications will give you interactive feed back.

Since FreeCAD is a heavy application, compiling can take a bit of time (about 10 minutes on a fast machine, 30 minutes (or more) on a slow one)

In-source building

If you are unsure then, due to its limitations, do not make an in-source build, create an out-of-source build as explained in the next section. However FreeCAD can be built in-source, which means that all the files resulting from the compilation stay in the same folder as the source code. This is fine if you are just looking at FreeCAD, and want to be able to remove it easily by just deleting that folder. But in case you are planning to compile it often, you are advised to make an out-of-source build, which offers many more advantages. The following commands will compile FreeCAD:

$ cd freecad (the folder where you cloned the freecad source)

If you want to use your system's copy of Pivy, which you most commonly will, then if not on Linux, set the compiler flag to use the correct pivy (via FREECAD_USE_EXTERNAL_PIVY=1). Using external Pivy became the default for Linux, during development of FreeCAD 0.16, so it does not need to be manually set when compiling this version onwards, on Linux. Also, set the build type to Debug if you want a debug build or Release if not. A Release build will run much faster than a Debug build. Sketcher becomes very slow with complex sketches if your FreeCAD is a Debug build. (NOTE: the space and "." after the cmake flags are CRITICAL!):

For a Debug build

$ make

Or for a Release build

$ make

Your FreeCAD executable will then reside in the "bin" folder, and you can launch it with:

$ ./bin/FreeCAD

How to repair your source code directory after accidentally running an in-source build.

This is a method, using Git, to repair your source code directory after accidentally running an in-source build.

1) delete everything in your source base directory EXCEPT the hidden .git folder
2) In terminal 'git reset --hard HEAD'
//any remnants of an 'in source' build will be gone.
3) delete everything from your 'out of source' build directory and start over again with cmake and a full new clean build.

Out-of-source build

If you intend to follow the fast evolution of FreeCAD, building in a separate folder is much more convenient. Every time you update the source code, cMake will then intelligently distinguish which files have changed, and recompile only what is needed. Out-of-source builds are specially handy when using the Git system, because you can easily try other branches without confusing the build system. To build out-of-source, simply create a build directory, distinct from your FreeCAD source folder, and, from the build folder, point cMake (or if using cmake-gui replace "cmake" in the code below with "cmake-gui") to the source folder:

mkdir freecad-build
cd freecad-build
cmake ../freecad (or whatever the path is to your FreeCAD source folder)

The FreeCAD executable will then reside in the "bin" directory (within your freecad-build directory).

Configuration options

There are a number of experimental or unfinished modules you may have to build if you want to work on them. To do so, you need to set the proper options for the configuration phase. Do it either on the command line, passing -D <var>:<type>=<value> options to cMake or using one of the availables gui-frontends (eg for Debian, packages cmake-qt-gui or cmake-curses-gui). Changing any options for cmake away from their default values, is much easier with cmake-gui or other graphical cmake applications than with cmake on the command line, as they will give you interactive feed back.

As an example, to configure FreeCAD with the Assembly module built just tick the box in a cmake gui application (e.g. cmake-gui) or on the command line issue:

cmake -D FREECAD_BUILD_ASSEMBLY:BOOL=ON ''path-to-freecad-root''

Possible options are listed in FreeCAD's root CmakeLists.txt file.

Qt designer plugin

If you want to develop Qt stuff for FreeCAD, you'll need the Qt Designer plugin that provides all custom widgets of FreeCAD. Go to


So far we don't provide a makefile -- but calling

qmake plugin.pro

creates it. Once that's done, calling


will create the library libFreeCAD_widgets.so. To make this library known to Qt Designer you have to copy the file to $QTDIR/plugin/designer


If you feel bold enough to dive in the code, you could take advantage to build and consult Doxygen generated FreeCAD's Source documentation

Making a debian package

If you plan to build a Debian package out of the sources you need to install those packages first:


#optional, used for checking if packages are standard-compliant

To build a package open a console, simply go to the FreeCAD directory and call


Once the package is built, you can use lintian to check if the package contains errors

#replace by the name of the package you just created
lintian your-fresh-new-freecad-package.deb


Note for 64bit systems

When building FreeCAD for 64-bit there is a known issue with the OpenCASCADE 64-bit package. To get FreeCAD running properly you might need to run the ./configure script with the additional define _OCC64 set:

./configure CXXFLAGS="-D_OCC64"

For Debian based systems this workaround is not needed when using the prebuilt package because there the OpenCASCADE package is built to set internally this define. Now you just need to compile FreeCAD the same way as described above.

Automatic build scripts

Here is all what you need for a complete build of FreeCAD. It's a one-script-approach and works on a fresh installed distro. The commands will ask for root password (for installation of packages) and sometime to acknowledge a fingerprint for an external repository server or https-subversion repository. These scripts should run on 32 and 64 bit versions. They are written for different versions, but are also likely to run on a later version with or without major changes.

If you have such a script for your preferred distro, please send it! We will incorporate it into this article.


These scripts provide a reliable way to install the correct set of dependencies required to build and run FreeCAD on Ubuntu. They make use of the FreeCAD Ubuntu PPA repositories, and should work on any version of Ubuntu targeted by the PPA. The 'daily' PPA targets recent versions of Ubuntu, and the 'stable' PPA targets all officially supported versions of Ubuntu.

This script installs dependencies for the daily development snapshot of FreeCAD.

sudo add-apt-repository --enable-source ppa:freecad-maintainers/freecad-daily && sudo apt-get update
# Install the dependencies needed to build FreeCAD
sudo apt-get build-dep freecad-daily
# Install the dependencies needed to run FreeCAD (and a build of FreeCAD itself)
sudo apt-get install freecad-daily

This script installs dependencies for the latest stable release of FreeCAD. (For Ubuntu 12.04, omit "--enable-source" from the add-apt-repository command.)

sudo add-apt-repository --enable-source ppa:freecad-maintainers/freecad-stable && sudo apt-get update
# Install the dependencies needed to build FreeCAD
sudo apt-get build-dep freecad
# Install the dependencies needed to run FreeCAD (and a build of FreeCAD itself)
sudo apt-get install freecad

(These scripts also install the PPA build of FreeCAD itself, as a side effect. You could then uninstall that while leaving the dependencies in place. However, leaving it installed will enable the package manager to keep the set of dependencies up to date, which is useful if you are following the development for a long time.)

After installing the dependencies, please see the generic instructions for getting the source code, running CMake, and compiling. The following script is an example of one way to do this.


# checkout the latest source
git clone https://github.com/FreeCAD/FreeCAD.git freecad

# go to source dir
cd freecad

# open cmake-gui window
cmake-gui .

# build configuration
cmake .

# build FreeCAD

OpenSUSE 12.2

No external Repositories are needed to compile FreeCAD 0.13 with this release. However, there is an imcompatability with python3-devel which needs to be removed. FreeCAD can be compiled from GIT similar to in OpenSUSE 12.2

# install needed packages for development
sudo zypper install gcc cmake OpenCASCADE-devel libXerces-c-devel \
python-devel libqt4-devel python-qt4 Coin-devel SoQt-devel boost-devel \
libode-devel libQtWebKit-devel libeigen3-devel gcc-fortran git swig
# create new dir, and go into it
mkdir FreeCAD-Compiled 
cd FreeCAD-Compiled
# get the source
git clone https://github.com/FreeCAD/FreeCAD.git free-cad
# Now you will have subfolder in this location called free-cad. It contains the source
# make another dir for compilation, and go into it
mkdir FreeCAD-Build1
cd FreeCAD-Build1 
# build configuration 
cmake ../free-cad
# build FreeCAD
# test FreeCAD
cd bin
./FreeCAD -t 0

Since you are using git, next time you wish to compile you do not have to clone everything, just pull from git and compile once more

# go into free-cad dir created earlier
cd free-cad
# pull
git pull
# get back to previous dir
cd ..
# Now repeat last few steps from before.
# make another dir for compilation, and go into it
mkdir FreeCAD-Build2
cd FreeCAD-Build2
# build configuration 
cmake ../free-cad
# build FreeCAD
# test FreeCAD
cd bin
./FreeCAD -t 0

Updating the source code

FreeCAD development happens fast, everyday or so there are bug fixes or new features. The cmake systems allows you to intelligently update the source code, and only recompile what has changed, making subsequent compilations very fast. Updating the source code with git or subversion is very easy:

#Replace with the location where you cloned the source code the first time
cd freecad
#If you are using git
git pull

Move into the appropriate build directory and run cmake again (as cmake updates the version number data for the Help menu, ...about FreeCAD), however you do not need to add the path to source code after "cmake", just a space and a dot:

#Replace with the location of the build directory
cd ../freecad-build
cmake .
