Pe distribuțiile linux recente, FreeCAD este în general ușor de complialt, deoarece toate dependențele sunt de obicei furnizate de managerul de pachete. În esență, implică 3 pași:
 * 1) Obținerea codului sursă al FreeCAD
 * 2) Obținerea dependențelor (depinde de pachetele FreeCAD)
 * 3) Configurați cu "cmake" și compilați cu "make"

Mai jos, veți găsi explicații detaliate ale întregului proces, unele build scripts, și particularitățile pe care le-ați putea întâlni. Dacă găsiți ceva greșit sau depășit în textul de mai jos (distribuțiile Linux se schimbă adesea) sau dacă utilizați o distribuție care nu este listată, vă rugăm să ne ajutați să o corectăm.



Obținerea sursei
Înainte de a putea să compilați FreeCAD, aveți nevoie de codul sursă. Există 3 moduri de a o obține:

Git
Cea mai rapidă și cea mai bună modalitate de a obține codul este clonarea repositorii git read-only acum găzduită pe GitHub (aveți nevoie de pachetul git instalat ):

Aceasta va plasa o copie a celei mai recente versiuni a codului sursă FreeCAD într-un nou director denumit "freecad-code".

For more information on using Git, and contributing code to the project, see Source code management.

Source package
Alternativ, puteți descărca un pachet sursă, dar acestea ar putea fi deja destul de vechi, deci este întotdeauna mai bine să obțineți cele mai recente surse prin intermediul git sau github.

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

Please note that FreeCAD's source code is around 500 MB in size; it may be three times as big if you clone the Git repository with its entire modification history. Getting all dependencies may require downloading 500 MB or more of new files; when these files are unpacked they may require 1500 MB or more in space. Also beware that the compilation process may generate up to 1500 MB of additional files as the system copies and modifies the entire source code. Therefore, be sure you have enough free space in your hard drive, at least 4 GB, when attempting compilation.

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.

If you already installed FreeCAD from the official repositories, you can install its build dependencies with this single line of code in a terminal:

However, if the version of FreeCAD in the repositories is old, the dependencies may be the wrong ones to compile a recent version of FreeCAD. Therefore, please verify that you have installed the following packages.

These packages are essential for any sort of compilation to succeed:
 * , installs the C and C++ compilers, the C development libraries, and the program.
 * , essential tool to configure the source of FreeCAD. You may also wish to install and  for a graphical option.
 * , essential tools to produce shared libraries.
 * , the standard base reporting utility is normally already installed in a Debian system, and allows you to programmatically distinguish between a pure Debian installation or a variant, such as Ubuntu or Linux Mint. Do not remove this package, as many other system packages may depend on it.

Compilation of FreeCAD uses the Python language, and it's also used at runtime as a scripting language. If you are using a Debian based distribution the Python interpreter is normally already installed.
 * , the tool that creates interfaces between C++ code and Python.
 * , the tool that creates interfaces between C++ code and Python.

Please check that you have Python 3 installed. Python 2 was obsoleted in 2019, so new development in FreeCAD is not tested with this version of the language.

The Boost libraries need to be installed:

The Coin libraries need to be installed:
 * , for Debian Jessie, Stretch, Ubuntu 16.04 to 18.10, or
 * , for Debian Buster, Ubuntu 19.04 and newer, as well as for Ubuntu 18.04/18.10 with the freecad-stable/freecad-daily PPAs added to your software sources.

Several libraries that deal with mathematics, triangulated surfaces, sorting, meshes, computer vision, cartographic projections, 3D visualization, the X11 Window system, XML parsing, and Zip file reading:

Python 2 and Qt4
This is not recommended for newer installations as both Python 2 and Qt4 are obsolete. To compile FreeCAD for Debian Jessie, Stretch, Ubuntu 16.04, using Python 2 and Qt4, install the following dependencies.

Python 3 and Qt5
To compile FreeCAD for Debian Buster, Ubuntu 19.04 and newer, as well as Ubuntu 18.04/18.10 with the freecad-stable/freecad-daily PPAs added to your software sources, install the following dependencies.
 * or
 * or

OpenCascade kernel
The OpenCascade kernel is the core graphics library to create 3D shapes. It exists in an official version OCCT, and a community version OCE. The community version is no longer recommended, as it's outdated.

For Debian Buster and Ubuntu 18.10 and newer, as well as Ubuntu 18.04 with the freecad-stable/freecad-daily PPAs added to your software sources, install the official packages.

For Debian Jessie, Stretch, Ubuntu 16.04 and newer, install the community edition packages.

Note that liboce*-dev includes the following libraries:

Optionally you can also install these extra packages:

Single command for Python 3 and Qt5
Requires Pyside2 available in Debian buster and the freecad-stable/freecad-daily PPAs.

Single command for Python 2 and Qt4
This is not recommended for newer installations as both Python 2 and Qt4 are obsolete.

Ubuntu 16.04 users please see also these Additional instructions.

Fedora
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

 * 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 :


 * 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)

Gentoo
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.

If FreeCAD is not available on portage, it is available on the waebbl overlay. The issue tracker on the waebbl overlay Github may help guide through some issues you may come across. The overlay provides freecad-9999, which you can choose to compile, or simply use to get the dependencies.

layman -a waebbl

Tumbleweed
The following commands will install the packages required for building FreeCAD with Qt5 and Python 3.

The following command will install Qt Creator and the GNU Project Debugger.

If any packages are missing, then you can check the Tumbleweed "FreeCAD.spec" file on the Open Build Service.

Also, check to see if there are any patches you need to apply (such as 0001-find-openmpi2-include-files.patch).

Leap
If there is a difference between the available packages on Tumbleweed and Leap, then you can read the Leap "FreeCAD.spec" file on the Open Build Service to determine the required packages.

Arch Linux
You will need the following libraries from the official repositories:


 * boost-libs
 * curl
 * desktop-file-utils
 * glew
 * hicolor-icon-theme
 * jsoncpp
 * libspnav
 * med
 * opencascade
 * shiboken2
 * xerces-c
 * pyside2
 * python-matplotlib
 * python-netcdf4
 * qt5-svg
 * qt5-webkit
 * qt5-webengine
 * boost
 * cmake
 * eigen
 * git
 * gcc-fortran
 * pyside2-tools
 * swig
 * qt5-tools
 * shared-mime-info

Also, make sure to check the AUR for any missing packages that are not on the repositories, currently:
 * coin
 * python-pivy
 * med

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...).

Try first locating the required libraries mentioned in third party libraries in your package manager. Beware that some of them might have a slightly different package name; search for, but also , , , and similar. If that is not possible try compiling those libraries yourself.

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.

Pivy
Pivy is not needed to build FreeCAD or to run it, but it is needed for the Draft 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 or elsewhere, you can compile pivy yourself:

By November 2015 the obsolete version of Pivy included with the FreeCAD source code will no longer compile on many systems. This isn't a big problem as normally you should get Pivy from your distribution's package manager; if you cannot find Pivy, you may have to compile it yourself, see Pivy compilation instructions.

Compilare FreeCAD
FreeCAD uses CMake as its main build system, as it's available on all major operating systems. Compiling with CMake is usually very simple and happens in two steps.


 * 1) CMake checks that every needed program and library is present on your system, and generates a  that is configured for the second step. FreeCAD has several configuration options to choose from, but it comes with sensible defaults. Some alternatives are detailed below.
 * 2) The compilation itself, which is done with the program, which generates the FreeCAD executables.

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)

You can build the code either in or out of the source directory. Out-of-source building is generally the best option.

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:

To build out-of-source, simply create a build directory,, distinct from your FreeCAD source folder, ; then from this build directory point to the right source folder. You can use or  instead of  in the instructions below as well. Once finishes configuring the environment, use  to start the actual compilation.

The option of  controls how many jobs (files) are compiled in parallel. The program prints the number of CPU cores in your system; by using it together with the  option you can choose to process as many files as you have cores, in order to speed up overall compilation of the program. In the example above, it will use all cores in your system except two; this will keep your computer responsive for other uses while compilation proceeds in the background. The FreeCAD executable will eventually appear in the directory. See also Compiling (speeding up) to improve compilation speed.

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:

In-source builds are fine if you want to compile a version of FreeCAD quickly, and don't intend to update the source code often. In this case, you can remove the compiled program and the source just by deleting a single folder.

Change to the source directory, and point to the present directory (denoted by a single point):

The FreeCAD executable will then reside in the directory.

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.

If you accidentally performed a compilation inside the source code directory, and would like to restore the contents to only the original source code, you can perform the following steps.

The first line clears the file. This ensures that the following clean and reset commands will affect everything in the directory and will not ignore items matching the expressions in. The second line deletes all files and directories that are not tracked by the git repository; then the last command will reset any changes to tracked files, including the first command which cleared the file.

If you do not clear the source directory, subsequent runs of may not capture new options to the system if the code changes.

Configuration
By passing different options to, you can change how FreeCAD is compiled. The syntax is as follows.

Where is the directory that contains the source code. The may be omitted in most cases. The space after the option may also be omitted.

For example, to avoid building the FEM Workbench:

All possible variables are listed in the file, located in the toplevel  directory. In this file, search for the word to get to the variables that can be set, and see their default values.

Alternatively, use the command to list the current configuration, and thus all variables that can be changed. You may also install and use to launch a graphical interface showing all the variables that can be modified. In the next sections we list some of the more relevant options that you may want to use.

For a Debug build
Create a build to troubleshoot crashes in FreeCAD. Beware that with this build the Sketcher becomes very slow with complex sketches.

Or for a Release build
Create a build to test code that doesn't crash. A build will run much faster than a  build.

Building against Python 3 and Qt5
By default, FreeCAD builds for Python 2 and Qt4. Since these two packages are obsolete, it is better to build for Python 3 and Qt5.

In a modern Linux distribution you only need to provide two variables specifying the use of Qt5, and the path to the Python interpreter.

Building for a specific Python version
If the default executable in your system is a symbolic link to Python 2,  will try to configure FreeCAD for this version. You can choose another version of Python by giving the path to a specific executable:

If that doesn't work, you may have to define additional variables pointing to the desired Python libraries and include directories:

It is possible to have several independent versions of Python in the same system, so the locations and version numbers of your Python files will depend on your particular Linux distribution. Use to display the version of Python that you are using currently; only the first two numbers are necessary; for example, if the result is, you need to specify the directories that relate to the 3.6 version. If you don't know the right directories, try searching for them with the command.

You may use in a terminal to determine the  directory, or  for Debian systems.

Building with Qt Creator against Python 3 and Qt5
To compile in Qt Creator add the appropriate variables to the bottom of. Again, specify the correct paths and Python version that you want to use.

Go to and choose  to compile the graphical version of FreeCAD, or  to compile only the command line version.

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

Go into an auxiliary directory of the source code, the run with the indicated project file to create a ; then run  to compile the plugin.

The library created is, which needs to be copied to , where is the directory that stores Qt binary libraries.

External or internal Pivy
Previously, a version of Pivy was included in the source code of FreeCAD (internal). If you wanted to use your system's copy of Pivy (external), you needed to use.

Using external Pivy became the default during development of FreeCAD 0.16, therefore this option does not need to be set manually anymore.

Doxygen documentation
If you have Doxygen installed you can build the source code documentation. See source documentation for instructions.

Additional documentation
The source code of FreeCAD is very extensive, and with CMake it's possible to configure many options. Learning to use CMake fully may be useful to choose the right options for your particular needs.

Compilarea unui pachet Debian
Dacă intenționați să compilați un pachet Debian din surse, trebuie să instalați mai întâi aceste pachete:

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

Actualizarea codului sursă
Dezvoltarea programului FreeCAD se întâmplă rapid, în fiecare zi sau în repetate rânduri există bug-uri sau noi caracteristici. Sistemele cmake vă permit să actualizați inteligent codul sursă și să recompilați doar ceea ce sa schimbat, făcând compilații ulterioare foarte rapid. Actualizarea codului sursă cu git sau subversiune este foarte ușoară:

The CMake system allows you to intelligently update the source code, and only recompile what has changed, making subsequent compilations faster.

Move to the location where the FreeCAD source code was first downloaded, and pull the new code:

Deplasați-vă în directorul corespunzător de compilare și rulați din nou cmake (deoarece cmake actualizează datele versiunii de versiune pentru meniul Ajutor, ... despre FreeCAD), cu toate acestea nu trebuie să adăugați calea la codul sursă după "cmake", doar un spațiu și un punct:

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:

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.

Scripturi automate de compilare
Aici este tot ceea ce aveți nevoie pentru o compilare completă a FreeCAD.Este o abordare cu un script și funcționează pe un distro nou instalat. Comenzile vor cere parola de root (pentru instalarea pachetelor) și cândva să or să recunoască o amprentă pentru un server de depozitare extern sau un repository de subversiune https.Aceste scripturi ar trebui rulați pe versiuni de 32 și 64 de biți. Ele sunt scrise pentru versiuni diferite, dar este de asemenea, probabil să ruleze pe o versiune ulterioară cu sau fără schimbări majore.

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

Ubuntu
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.

(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.)

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

Once you install the package from the  repository, it will supersede the FreeCAD executable that is available from the Universe Ubuntu repository. The executable will be named simply, and not.

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

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

Fedora 27/28/29
Posted by user [PrzemoF] in the forum.

{ echo "~/$MAIN_DIR already exist. Quitting.."; exit; } cd $MAIN_DIR git clone https://github.com/FreeCAD/FreeCAD.git mkdir $BUILD_DIR

Arch using AUR
Arch User Repository (AUR) is a collection user made recipes to build packages which are not officially supported by distribution maintainers / community. They are usually safe. You can see who maintain the package and for how long he did. It is recommended to check construction files. Also non open source software are available in this area even if maintained by the official owning company.

Prerequisite : git

Steps :
 * 1) Open a terminal. Optionally create a directory eg. . Optionally change directory eg..
 * 2) Clone the AUR repository :
 * 3) Enter AUR repository folder :
 * 4) Compile using Arch makepkg : . The -s or --syncdeps flag will also install required dependencies.
 * 5) Install created package : or double click on the pkgname-pkgver.pkg.tar.xz inside your file browser.

To update FreeCAD to latest build just repeat from step 3. Update AUR repo when there is some breaking change in the recipe or new features using inside the folder.
