CompileOnUnix/pt

On recent linux distributions, FreeCAD is generally easy to build, since all dependencies are usually provided by the package manager. It basically involves 3 steps:


 * 1) Getting the FreeCAD source code
 * 2) Getting the dependencies (packages FreeCAD depends upon)
 * 3) Compiling with "cmake . && make"

Below, you'll find detailed explanations of the whole process and particularities you might encounter. If you find anything wrong or out-of-date in the text below (Linux distributions change often), or if you use a distribution which is not listed, please help us correcting it.

Getting the source
Before you can compile FreeCAD, you need the source code. There are 3 ways to get it:

Git
The quickest and best way to get the code is to clone the read-only git repository (you need the git package installed): git clone git://git.code.sf.net/p/free-cad/code 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 first time you try connecting to the free-cad.git.sourceforge.net host, you will receive a message asking to authenticate the sourceforge SSH key, which is normally safe to accept (you can check their SSH keys on the sourceforge website if you are not sure)

Github
There is an always up to date FreeCAD repository on Github: github.com/FreeCAD/FreeCAD_sf_master

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. Depending on your distribution, there are several ways to obtain a source package:


 * Official FreeCAD source packages (distribution-independent): https://sourceforge.net/projects/free-cad/files/FreeCAD%20Source/
 * Debian: http://packages.debian.org/source/sid/freecad
 * Ubuntu: http://packages.ubuntu.com/source/precise/freecad

Getting the dependencies
To compile FreeCAD under Linux you have to install all libraries mentioned in Third Party Libraries first. On recent distributions, this is generally just a matter of installing a couple of packages:

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. Below are listed all packgages you need to install. 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. build-essential cmake python python-matplotlib libtool either: libcoin60-dev (Debian Wheezy, Wheezy-backports, Ubuntu 13.04 and before) or: libcoin80-dev (Debian unstable(Jesse), testing, Ubuntu 13.10 and forward, See Additional instruction below]) libsoqt4-dev libxerces-c-dev libboost-dev libboost-filesystem-dev libboost-regex-dev libboost-program-options-dev libboost-signals-dev libboost-thread-dev libqt4-dev libqt4-opengl-dev qt4-dev-tools python-dev python-pyside pyside-tools either: libopencascade-dev (official opencascade version) or: liboce*-dev (opencascade community edition) oce-draw gfortran libeigen3-dev libqtwebkit-dev libshiboken-dev libpyside-dev libode-dev swig libzipios++-dev libfreetype6 libfreetype6-dev 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-visualation-dev liboce-ocaf-lite-dev. You may have to install these pacakges 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)

Fedora
You need the following packages: cmake doxygen swig gcc-gfortran gettext dos2unix desktop-file-utils libXmu-devel freeimage-devel mesa-libGLU-devel OCE-devel python python-devel python-pyside-devel boost-devel tbb-devel eigen3-devel qt-devel qt-webkit-devel ode-devel xerces-c xerces-c-devel opencv-devel smesh-devel coin2-devel soqt-devel freetype freetype-devel And optionally: libspnav-devel (for 3Dconnexion devices support like the Space Navigator or Space Pilot) pivy ( https://bugzilla.redhat.com/show_bug.cgi?id=458975 Pivy is not mandatory but needed for the Draft module ) Building FreeCAD with coin3 is still more hassle on Fedora, since only coin2 is provided in the official repos, but if you wish so anyway, you can avoid to rebuild all the coin3 / soqt / pivy suite by installing coin3-ready packages from http://www.zultron.com/rpm-repo/

Fedora 20
Install the "free" and "nonfree" Fedora repositories: $ su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'

Now, install the required packages: $ sudo yum install cmake doxygen swig gcc-gfortran gettext dos2unix desktop-file-utils libXmu-devel freeimage-devel mesa-libGLU-devel OCE-devel python python-devel boost-devel tbb-devel eigen3-devel qt-devel qt-webkit-devel ode-devel xerces-c xerces-c-devel opencv-devel smesh-devel freetype freetype-devel gcc-c++ git libspnav-devel shiboken-devel python-pyside-devel python-matplotlib wget mercurial Coin2-devel Create a symbolic link so that cmake will find the Coin/Inventor files: $ sudo ln -s /usr/include/Coin2/Inventor /usr/include/Inventor Download the tarball for SoQt-1.5.0-10: $ cd ~/Downloads/ $ wget http://pkgs.fedoraproject.org/repo/pkgs/SoQt/SoQt-1.5.0.tar.gz/9f1e582373d66f556b1db113a93ac68e/SoQt-1.5.0.tar.gz $ tar -xvf SoQt-1.5.0.tar.gz Compile SoQt: $ cd SoQt-1.5.0/ $ ./configure $ make $ sudo make install Download, build and install pivy: $ cd ~/Downloads/ $ hg clone https://bitbucket.org/Coin3D/pivy pivy-code $ cd pivy-code $ python setup.py build $ sudo python setup.py install Skip to Compile FreeCAD

Gentoo
You need the following packages to build FreeCAD: dev-cpp/eigen dev-games/ode dev-libs/boost dev-libs/xerces-c dev-python/pivy dev-python/PyQt4 media-libs/coin media-libs/SoQt sci-libs/opencascade-6.5 sys-libs/zlib virtual/fortran x11-libs/qt-gui x11-libs/qt-opengl x11-libs/qt-svg x11-libs/qt-webkit x11-libs/qt-xmlpatterns dev-lang/swig-2.0.4-r1 app-admin/eselect-python-20091230 dev-lang/python-2.7.2-r3 dev-util/cmake-2.8.4 sys-apps/findutils-4.4.0 freetype Since latest opencascade is not available, you might want to compile opencascade too, hence the following additional libaries are needed: media-libs/ftgl virtual/opengl x11-libs/libXmu dev-lang/tcl-8.5.9 dev-lang/tk-8.5.9-r1 dev-tcltk/itcl-3.4_beta1 dev-tcltk/itk-3.4_pre20090417 dev-tcltk/tix-8.4.3 x11-libs/gl2ps sys-devel/automake-1.11 sys-devel/autoconf-2.68 sys-devel/libtool dev-java/java-config-2.1.11-r3

OpenSUSE
You need the following packages: 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 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 one-click install here: Eigen3: http://software.opensuse.org/search?q=eigen3&baseproject=openSUSE%3A12.1&lang=en&exclude_debug=true swig: http://software.opensuse.org/search?q=swig&baseproject=openSUSE%3A12.1&lang=en&exclude_debug=true Also, note that Eigen3 Library from Factory Education was causing problems sometimes, so use the one from KDE 4.8 Extra repo

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

Eigen 3
The Eigen3 library is now required by the Sketcher module. This library is only available starting from Ubuntu 11.10 repositories. For prior Ubuntu releases, you can either download it from here and install it manually, or add the FreeCAD Daily Builds PPA to your software sources before installing it through one of the means listed below.

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 yourself for your distribution if one is available. At least from Debian Lenny and Ubuntu Intrepid on 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

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
 * 1) Install OCC build-deps

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

sudo dpkg -i libopencascade6.2-0_6.2.0-7_i386.deb libopencascade6.2-dev_6.2.0-7_i386.deb Alternatively, you can download and compile the latest version from opencascade.org:
 * 1) Install the resulting library debs

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: make 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

SoQt
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 debuild 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
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. At the time of writing, Pivy is very new and might not have made its way into your distribution repository. If you cannot find Pivy in your distribution's packages repository, you can grab debian/ubuntu packages on the FreeCAD download page:

http://sourceforge.net/projects/free-cad/files/FreeCAD%20Linux/ or compile pivy yourself:

Pivy compilation instructions

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.

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

In-source building
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 installed pivy from source, set the compiler flag to use the correct pivy (via FREECAD_USE_EXTERNAL_PIVY=1). Also, set the build type to debug. (NOTE: the "." and space after the cmake flags are CRITICAL!): $ cmake -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug. $ make Your FreeCAD executable will then reside in the "bin" folder, and you can launch it with: $ ./bin/FreeCAD

Out-of-source build
If you intend to follow the fast evolution of FreeCAD, building in a separate folder is much more convenient. Everytime 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 to the source folder: mkdir freecad-build cd freecad-build cmake ../freecad (or whatever the path is to your FreeCAD source folder) make 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 : = options to cMake or using one of the availables gui-frontends (eg for Debian, packages cmake-qt-gui or cmake-curses-gui).

As an example, to configure on the command line with the Assembly module built, issue: cmake -D FREECAD_BUILD_ASSEMBLY:BOOL=ON path-to-freecad-root Possible options are listed in FreeCAD's root CmakeLists.txt file.

Using autotools
Autotools has been deprecated in favour of cMake, but old versions of FreeCAD were able to be built with Autotools. You must have automake and libtool installed on your system; on Debian/Ubuntu: aptitude install automake libtool If you got the sources with git or subversion, then the very first step must be ./autogen.sh that creates the configure script and more. For the build process itself we provide a configure script. Just type ./configure To get everything configured. If you want an overview of all options you can specify, you can type ./configure --help Normally you need none of them - unless you have one of your libraries installed in a really uncommon directory. After configuration has finished, compiling FreeCAD is as simple as make If any error occurs while building from sources, please double-check this page and README.Linux file, then you could jump to the Bug Tracker on SourceForge, choose Any for status and click the Browse button to see previous reports on compile problems. After having built FreeCAD successfully, do make install to install it onto your machine. The default install directory is ~/FreeCAD It will be installed in a FreeCAD folder in your home folder, so you don't need root privileges. Instead of make install, you can also do checkinstall In this way FreeCAD will be installed by your package management system, so you can uninstall it easily later. But since all of FreeCAD installation resides into one single directory, just removing the FreeCAD directory is a valid way to uninstall too.

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 freecad/src/Tools/plugins/widget So far we don't provide a makefile -- but calling qmake plugin.pro creates it. Once that's done, calling make 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

Doxygen
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: dh-make devscripts lintian (optional, used for checking if packages are standard-compliant) To build a package open a console, simply go to the FreeCAD directory and call debuild Once the package is built, you can use lintian to check if the package contains errors lintian your-fresh-new-freecad-package.deb (replace by the name of the package you just created)

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.

Automake macros
The configure script of FreeCAD makes use of several automake macros that are sometimes not installed with their packages: bnv_have_qt.m4, coin.m4, and soqt.m4. If needed (error while configuring), google for them and you will find them easily. They are just simple scripts that you need to put in your /usr/share/aclocal folder.

Fedora 13
To build & install FreeCAD on Fedora 13, a few tips and tricks are needed:
 * Install a bunch of required packages, most are available from the Fedora 13 repositories
 * Download and build xerces
 * Download and build OpenCascade. Need to point it to xmu: ./configure --with-xmu-include=/usr/include/X11/Xmu --with-xmu-library=/usr/lib
 * Download and build Pivy. You have to remove 2 references to non existent "SoQtSpaceball.h" from pivy/interfaces/soqt.i Commenting out those two lines allow the build & install to work.
 * Configure Freecad. You will need to point it to a few things: ./configure --with-qt4-include=/usr/include --with-qt4-bin=/usr/lib/qt4/bin --with-occ-lib=/usr/local/lib --with-occ-include=/usr/local/inc --with-xercesc-lib=/usr/local/lib
 * make - hits a problem where the build is breaking because the ldflags for soqt are set to "-LNONE" which made libtool barf. My hackish workaround was to modify /usr/lib/Coin2/conf/soqt-default.cfg so that the ldflags are "" instead of "-LNONE". After this -> success !
 * make install

Ubuntu Lucid
In Ubuntu Lucid, you don't need the qtwebkit-dev, since it is included into qt4-dev.

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. This scripts should run on 32 and 64 bit versions. They are written for distinct version, but are also likely to run on a later version with or without minor changes.

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

Note that this script starts by adding the FreeCAD Daily Builds PPA repository so it can proceed with the Eigen3 library (libeigen3-dev) installation. If you already have this library installed on your system, you can remove the first line.

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: cd freecad (or where you cloned the source code the first time) git pull (if you are using git) 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: cd ../freecad-build (or wherever your build directory is located) cmake. make
