There are two ways to download the source: manually and using CMake. We explain the manual method first, as the CMake method follows from that. Using curl or wget or any browser download the source from the TBB website. For example, the latest source code version at the time of writing of this blog post is 4.4. World's #1 PDF SDK Library for Web, Mobile, Server, Desktop. // RUN THIS IF YOU HAVE ANY CARD (INCL. NVIDIA) AND WANT THE OPEN SOURCE 'OpenCL' DRIVERS. Cmake -DBUNDLE=miner -DETHSTRATUM=1. Run make next: make -j8 Afterwards, run cmake again, but on your current directory, the build directory. Launching ethminer. Once installation succedes, go to the ethminer directory (from the build.

Overview
This page describes how to compile the FreeCAD source code on MacOS X. For other platforms, see Compiling.
Cmake Command Not Found Mac
These instructions have been tested on macOS Catalina with standard XCode 11.6. It is known to work on macOS BigSur Beta with XCode 12.0 beta. If you plan to use XCode Beta, please be sure to download Command Line Tools add on through a dmg package to workaround some libz dependency issues.
This page serves as a quick start, and is not intended to be comprehensive with regard to describing all the available build options.
If you just want to evaluate the latest pre-release build of FreeCAD, you can download pre-built binaries from here.
Install Prerequisites
The following software must be installed to support the build process.
Homebrew Package Manager
Homebrew is a command line based package manager for macOS. The Homebrew main page provides an installation command line that you simply paste into a terminal window.
CMake
CMake is a build tool that generates a build configuration based on variables you specify. You then issue the 'make' command to actually build that configuration. The command-line version of CMake is automatically installed as part of the Homebrew installation, above. If you prefer to use a GUI version of CMake, you can download it from here.
Install Dependencies
FreeCAD maintains a Homebrew 'tap' which installs the required formulas and dependencies. Issue the following brew commands in your terminal.
Notes:
- 'brew install' may take quite a while, so you may want go grab a beverage. :-).
- Homebrew is currently shipping with Boost 1.73, which contains a bug to compile FreeCAD please edit the file /usr/local/opt/boost/include/boost/geometry/index/detail/rtree/visitors/insert.hpp and on line 265 declare MembersHolder::visitor as being a Public value by replacing : MembersHolder::visitor with : public MembersHolder::visitor
Get the source
In the following instructions, the source and build folders are created side-by-side under
but you can use whatever folders you want.
The following command will clone the FreeCAD git repository into a directory called FreeCAD-git.
Create the build folder.
Run CMake
Next, we will run CMake to generate the build configuration. Several options must be passed to CMake. The following table describes the options and gives some background.
CMake Options
| Name | Value | Notes |
|---|---|---|
| CMAKE_BUILD_TYPE | Release (STRING) | Release or Debug. Debug is generally used for developer-level testing but may also be required for user-level testing and troubleshooting. |
| BUILD_QT5 | 1 (BOOL) | Required to build with Qt5. |
| CMAKE_PREFIX_PATH | '/usr/local/opt/qt5/lib/cmake/;' ... (PATH) | Required to build with Qt5. See note below. You also need to add path to VTK libraries and NGLIB libraries cmake configuration file. |
| FREECAD_CREATE_MAC_APP | 1 (BOOL) | Create a FreeCAD.app bundle at the location specified in CMAKE_INSTALL_PREFIX, when the 'make install' command issued. |
| CMAKE_INSTALL_PREFIX | './..' (PATH) | Path where you want to generate the FreeCAD.app bundle. |
| FREECAD_USE_EXTERNAL_KDL | 1 (BOOL) | Required. |
| BUILD_FEM_NETGEN | 1 (BOOL) | Required. |
Note: Command line to generate CMAKE_PREFIX_PATH:
CMake GUI
Open the CMake app, and fill in the source and build folder fields. In this example, it would be /Users/username/FreeCAD/FreeCAD-git for the source, and /Users/username/FreeCAD/build for the build folder.
Next, click the Configure button to populate the list of configuration options. This will display a dialog asking you to specify what generator to use. Leave it at the default Unix Makefiles. Configuring will fail the first time because there are some options that need to be changed. Note: You will need to check the Advanced checkbox to get all of the options.
Set options from the table above, then click Configure again and then Generate.
CMake command line
Mac Upgrade Cmake
Enter the following in the terminal.
Run make
Install Cmake On Mac
Finally, from a terminal run make to compile and link FreeCAD, and generate the app bundle.
The -j option specifies how many make processes to run at once. One plus the number of CPU cores is usually a good number to use. However, if compiling fails for some reason, it is useful to rerun make without the -j option, so that you can see exactly where the error occurred.
See also Compiling - Speeding up.
If make finishes without any errors, you can now launch FreeCAD by double clicking the executable in the Finder.
Updating from Github
FreeCAD development happens fast; every day or so there are bug fixes or new features. To get the latest changes, use git to update the source directory (see Source code management), then re-run the CMake and make steps above. It is not usually necessary to start with a clean build directory in this case, and subsequent compiles will generally go much faster than the first one.
Building with Qt4 and Python 2.7
FreeCAD has transitioned from Qt 4 to Qt 5 as well as homebrew. Qt 4 is no longer available as an option for new build on macOS following Qt 5 transition. Python 2.7 has been deprecated within homebrew and upcoming macOS and we do not support it anymore for macOS build either.
Troubleshooting
Segfault on Qt5 launch
Cmake For Mac
If Qt4 was previously installed via brew, and you then build with Qt5, you may get a EXC_BAD_ACCESS (SEGSEGV) exception when launching the new Qt5 build. The fix for this is to manually uninstall Qt4.
Fortran
'No CMAKE_Fortran_COMPILER could be found.' during configuration - Older versions of FreeCAD will need a fortran compiler installed. With Homebrew, do 'brew install gcc' and try configuring again, giving cmake the path to Fortran ie -DCMAKE_Fortran_COMPILER=/opt/local/bin/gfortran-mp-4.9 . Or, preferably use a more current version of FreeCAD source!
OpenGL
See OpenGL on MacOS for OpenGL issues when Qt 4.8 and earlier are used on MacOS.
FreeType
When using CMake versions older than 3.1.0, it's necessary to set CMake variable FREETYPE_INCLUDE_DIR_freetype2 manually, eg /usr/local/include/freetype2
