This page explains how to compile the latest FreeCAD source code on Mac OS X.
{{docnav|CompileOnUnix|Compiling (Speeding up)}}


This page describes how to compile the latest FreeCAD source on macOS X. ''Latest'' means the most recent commit to the master branch of the FreeCAD github repository.
== Prerequisites ==
First of all, you will need to install the following software.


These instructions have been tested on macOS High Sierra
=== Xcode Development Tools ===

Unless you want to use the Xcode IDE for FreeCAD development, you will only need to install the Command Line Tools. To do this on 10.9 and later, open Terminal, run the following command, and then click Install in the dialog that comes up.
This page serves as a quick start, and is not intended to be comprehensive with regard to describing all the available build options.
<pre>

xcode-select --install
If you just want to evaluate the latest pre-release build of FreeCAD, you can download pre-built binaries [https://github.com/FreeCAD/FreeCAD/releases from here].
</pre>

For other versions of OS X, you can get the package from the Apple developer [https://developer.apple.com/downloads/index.action?q=xcode downloads page] (sign in with the same Apple ID you use for other Apple services). Specifically, you will need to download Development Tools 3.2 for OS X 10.6, and Command Line Tools 4.8 for OS X 10.8.
== 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 [https://brew.sh/ Homebrew main page] provides an installation command line that you simply paste into a terminal window.


=== CMake ===
=== CMake ===
CMake is 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 [https://www.cmake.org/downloadDownload here].
Install the latest version of CMake from http://www.cmake.org/download. Although Homebrew will also install CMake, it only installs the command line executable.


=== Homebrew ===
== Install Dependencies ==
To install Homebrew, enter the following in Terminal:
FreeCAD maintains a Homebrew 'tap' which installs the required formulas and dependencies. Issue the following brew commands in your terminal.

<br />
<pre>
<pre>
brew tap freecad/freecad
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install eigen
brew install --only-dependencies freecad --with-packaging-utils
</pre>
</pre>
Notes:
== Getting the source ==
# 'brew install' may take quite a while, so you may want go grab a beverage. :-)
In this guide, the source and build folders are created in '''/Users/username/FreeCAD''', but you can of course use whatever folder you want.

== Get the source ==
In the following instructions, the source and build folders are created side-by-side under

/Users/username/FreeCAD

but you can use whatever folders you want.
<pre>
<pre>
mkdir ~/FreeCAD
mkdir ~/FreeCAD
cd ~/FreeCAD
cd ~/FreeCAD
</pre>
</pre>
The following command will clone the FreeCAD git repository into a directory called FreeCAD-git.
To get the FreeCAD source code, run:
<pre>
<pre>
git clone git://git.code.sf.net/p/free-cad/code FreeCAD-git
git clone https://github.com/FreeCAD/FreeCAD FreeCAD-git
</pre>
</pre>
Create the build folder.
Alternatively, you can use the github mirror: https://github.com/FreeCAD/FreeCAD_sf_master.git

== Installing the Dependencies ==
All of the needed libraries can be installed using Homebrew.
<pre>
brew tap homebrew/science
brew tap sanelson/freecad
brew install boost eigen freetype oce python qt pyside pyside-tools xerces-c
brew install --without-framework --without-soqt sanelson/freecad/coin
brew install --HEAD pivy
</pre>
== Compiling FreeCAD ==
First, create a new folder for the build:
<pre>
<pre>
mkdir ~/FreeCAD/build
mkdir ~/FreeCAD/build
</pre>
</pre>
<br />
Now you will need to run CMake to generate the build files. Open the CMake app, and fill in the source and build folder fields. In this case, it would be '''/Users/username/FreeCAD/FreeCAD-git''' for the source, and '''/Users/username/FreeCAD/build''' for the build folder.


== Run CMake ==
Next, click the '''Configure''' button. 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.

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 ===

|}
Note: The above paths for OCE and Python are for versions 0.16.1 and 2.7.9, respectively -- change as needed.


Note: Command line to generate CMAKE_PREFIX_PATH:
Now click '''Configure''' again and then '''Generate'''.
<pre>
ls -d $(brew list -1 | grep qt | tail -1 | xargs brew --cellar)/*/lib/cmake
</pre>


=== CMake GUI ===
Finally, run '''make''' to compile FreeCAD.
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 ===
Enter the following in the terminal.
<pre>
$cd ~/FreeCAD/build
$cmake \
-DCMAKE_BUILD_TYPE="Release" \
-DBUILD_QT5=1 \
-DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake" \
-DFREECAD_USE_EXTERNAL_KDL=1 \
-DBUILD_FEM_NETGEN=1 \
-DFREECAD_CREATE_MAC_APP=1 \
-DCMAKE_INSTALL_PREFIX="./.." \
../FreeCAD-git/

</pre>

== Run make ==
Finally, from a terminal run '''make''' to compile and link FreeCAD, and generate the app bundle.
<pre>
<pre>
cd ~/FreeCAD/build
cd ~/FreeCAD/build
make –j3
make -j5 install
</pre>
</pre>
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.

CompileOnUnix
Compiling (Speeding up)

This page describes how to compile the latest FreeCAD source on macOS X. Latest means the most recent commit to the master branch of the FreeCAD github repository.

These instructions have been tested on macOS High Sierra

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 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.


brew tap freecad/freecad
brew install eigen
brew install --only-dependencies freecad --with-packaging-utils

Notes:

  1. 'brew install' may take quite a while, so you may want go grab a beverage. :-)

Get the source

In the following instructions, the source and build folders are created side-by-side under

/Users/username/FreeCAD

but you can use whatever folders you want.

mkdir ~/FreeCAD
cd ~/FreeCAD

The following command will clone the FreeCAD git repository into a directory called FreeCAD-git.

git clone https://github.com/FreeCAD/FreeCAD FreeCAD-git

Create the build folder.

mkdir ~/FreeCAD/build


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/Cellar/qt@5.6/5.6.2/lib/cmake" (PATH) Required to build with Qt5. See note below.
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:

ls -d $(brew list -1 | grep qt | tail -1 | xargs brew --cellar)/*/lib/cmake

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

Enter the following in the terminal.

$cd ~/FreeCAD/build
$cmake \
  -DCMAKE_BUILD_TYPE="Release"   \
  -DBUILD_QT5=1                  \
  -DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake"  \
  -DFREECAD_USE_EXTERNAL_KDL=1   \
  -DBUILD_FEM_NETGEN=1           \
  -DFREECAD_CREATE_MAC_APP=1     \
  -DCMAKE_INSTALL_PREFIX="./.."  \
  ../FreeCAD-git/

Run make

Finally, from a terminal run make to compile and link FreeCAD, and generate the app bundle.

cd ~/FreeCAD/build
make -j5 install

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

FreeCAD has transitioned from Qt 4 to Qt 5. If you need to build with Qt4, the following additional steps are required.

  1. Append '--with-qt4' to the 'brew install' command.
  2. Do not specify BUILD_QT5 CMake option.
  3. Do not specify CMAKE_PREFIX_PATH CMake option

After you install Qt4, if you want to switch to building with Qt5, you will need to uninstall Qt4.

brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt

Troubleshooting

Segfault on Qt5 launch

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.

brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt-legacy-formula

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
