These are step-by-step instructions to compile Natron on OS X.
OS X 10.6 (a.k.a. Snow Leopard) and newer are supported when building with MacPorts, and Homebrew can be used to compile it on the latest OS X.
The official Natron and plugins binaries are built using the section about MacPorts in these instructions to prepare the system, and the launchBuildMain.sh
build script found in the tools/jenkins
directory. The script takes care of everything, from checking out sources, to compiling and packaging.
These binaries are built on an OS X 10.9 (Mavericks) virtual machine with Xcode 6.2. Note that Mavericks can not be downloaded anymore from the 10.14 (High Sierra) App Store, so you will need to use a Mac with an older system (up to 10.13), or look for alternatives.
The build system is based on MacPorts with the custom ports found in the tools/MacPorts
directory in the sources. We are not using Homebrew, because MacPorts is easier to customize.
Everything is compiled using the latest version of Clang rather than the version bundled with Xcode, in order to have full OpenMP support.
Natron can be built on a virtual machine, in order to target older versions of OS X / macOS. Due to the OS X Software License Agreement, OS X may only be virtualized on Mac hardware. The excellent blog post OS X on OS X (archive) gives all the instructions to install an OS X virtual machine.
In order to have Natron compiling, first you need to install the required libraries.
There are two exclusive options: using MacPorts or using Homebrew.
Homebrew is easier to set up than MacPorts, but cannot build universal binaries.
You need an up to date MacPorts version. Just download it and install it from http://www.macports.org, and execute the following commands in a terminal:
sudo port selfupdate
sudo port upgrade outdated
Then, you should add the "ports" provided by Natron. Edit as root the file /opt/local/etc/macports/sources.conf
(as in sudo nano /opt/local/etc/macports/sources.conf
) and add the following line at the beginning, with the path to the Natron sources (yes, there are three slashes after file:
):
file:///Users/your_username/path_to_sources/Natron/tools/MacPorts
Then, create the index file:
(cd /Users/your_username/path_to_sources/Natron/tools/MacPorts; portindex)
It is also recommended to add the following line to /opt/local/etc/macports/variants.conf
:
-x11 +no_x11 +bash_completion +no_gnome +quartz +natron
The libtool that comes with OS X 10.6 Snow Leopard does not work well with clang-generated binaries, so on this system you may have to substitute it with the libtool provided by MacPort's cctools
package, using sudo mv /usr/bin/libtool /usr/bin/libtool.orig; sudo mv /Developer/usr/bin/libtool /Developer/usr/bin/libtool.orig; sudo ln -s /opt/local/bin/libtool /usr/bin/libtool; sudo ln -s /opt/local/bin/libtool /Developer/usr/bin/libtool
Now, use libjpeg-turbo instead of jpeg:
sudo port -f uninstall jpeg
sudo port -v -N install libjpeg-turbo
And finally install the required packages:
sudo port -v -N install opencolorio -quartz -python27
sudo port -v -N install qt4-mac boost cairo expat
sudo port -v -N install gsed gawk coreutils findutils
sudo port -v -N install cmake keychain
sudo port -v -N install py27-pyside py37-sphinx py37-sphinx_rtd_theme
sudo port select --set python python27
sudo port select --set python2 python27
sudo port select --set python3 python37
sudo port select --set sphinx py37-sphinx
Create the file /opt/local/lib/pkgconfig/glu.pc containing GLU configuration, for example using the following comands:
sudo -s
cat > /opt/local/lib/pkgconfig/glu.pc << EOF
prefix=/usr
exec_prefix=\${prefix}
libdir=\${exec_prefix}/lib
includedir=\${prefix}/include
Name: glu
Version: 2.0
Description: glu
Requires:
Libs:
Cflags: -I\${includedir}
EOF
If you intend to build the openfx-io plugins too, you will need these additional packages:
sudo port -v -N install x264
sudo port -v -N install libvpx +highbitdepth
sudo port -v -N install ffmpeg +gpl2 +highbitdepth +natronmini
sudo port -v -N install libraw +gpl2
sudo port -v -N install openexr
sudo port -v -N install opencolorio -quartz -python27
sudo port -v -N install openimageio +natron
sudo port -v -N install seexpr
and for openfx-arena (note that it installs a version of ImageMagick without support for many image I/O libraries):
sudo port -v -N install librsvg
sudo port -v -N install ImageMagick +natron
sudo port -v -N install poppler
sudo port -v -N install librevenge
sudo port -v -N install libcdr-0.1
sudo port -v -N install libzip
sudo port -v -N install sox
and for openfx-gmic:
sudo port -v -N install fftw-3
Install homebrew from http://brew.sh/
Qt 4 is not supported in homebrew. Please enable the community-maintained recipe using:
brew tap cartr/qt4
brew install cartr/qt4/qt@4 cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2
Patch the qt4 recipe to fix the stack overflow issue (see QTBUG-49607, homebrew issue #46307, MacPorts ticket 49793).
Patching a homebrew recipe is explained in the homebrew FAQ.
brew edit cartr/qt4/qt@4
and before the line that starts with head
, add the following code:
patch :p0 do
url "https://bugreports.qt.io/secure/attachment/52520/patch-qthread-stacksize.diff"
sha256 "477630235eb5ee34ed04e33f156625d1724da290e7a66b745611fb49d17f1347"
end
Install libraries:
brew install cairo expat
brew install gnu-sed gawk coreutils findutils
brew install cmake keychain sphinx-doc
/usr/local/opt/sphinx-doc/libexec/bin/pip3 install sphinx_rtd_theme
brew install --build-from-source qt --with-mysql
On macOS Sierra, install the sierra-compatible recipe (to be used only in Sierra, since this builds Qt from sources and takes a while):
brew install --build-from-source cartr/qt4/qt --with-mysql
Then install pyside (the boneyard tap is for pyside, which does not yet build with Qt5 and was thus removed from the homebrew core):
brew install pyside@1.2 pyside-tools@1.2
The last command above will take a while, since it builds from sources, and should finally tell you do do the following if the homebrew.pth
file does not exist:
mkdir -p ~/Library/Python/2.7/lib/python/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth
sudo ln -s ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth /Library/Python/2.7/lib/python/site-packages/homebrew.pth
To install the openfx-io and openfx-misc sets of plugin, you also need the following:
brew install ilmbase openexr freetype fontconfig ffmpeg opencolorio openimageio
# openfx-io still requires SeExpr 2.11, but homebrew was updated to 3.0.1 on July 6, 2020
cd $( brew --prefix )/Homebrew/Library/Taps/homebrew/homebrew-core
git checkout 4abcbc52a544c293f548b0373867d90d4587fd73 Formula/seexpr.rb
brew unlink seexpr
brew install seexpr
brew link seexpr
brew switch seexpr 2.11
git checkout master Formula/seexpr.rb
If you ever need to get back to using the latest version of seexpr:
brew switch seexpr 3.0.1
To install the openfx-arena set of plugin, you also need the following:
brew install librsvg poppler librevenge libcdr libzip sox
brew uninstall imagemagick
brew install imagemagick --with-hdri --with-librsvg --with-quantum-depth-32 --with-pango
To install the openfx-gmic set of plugin, you also need the following:
brew install fftw
also set the correct value for the pkg-config path (you can also put this in your .bash_profile):
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig:/usr/local/opt/cairo/lib/pkgconfig:/usr/local/opt/icu4c/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig
The following is not necessary if a patched Qt was already installed by the standard MacPorts or homebrew procedures above.
See QTBUG-49607, homebrew issue #46307, MacPorts ticket 49793.
wget https://download.qt.io/official_releases/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz
tar zxvf qt-everywhere-opensource-src-4.8.7.tar.gz
cd qt-everywhere-opensource-src-4.8.7
wget https://raw.githubusercontent.com/Homebrew/patches/480b7142c4e2ae07de6028f672695eb927a34875/qt/el-capitan.patch
patch -p1 < el-capitan.patch
wget https://bugreports.qt.io/secure/attachment/52520/patch-qthread-stacksize.diff
patch -p0 < patch-qthread-stacksize.diff
Then, configure using:
./configure -prefix /opt/qt4 -pch -system-zlib -qt-libtiff -qt-libpng -qt-libjpeg -confirm-license -opensource -nomake demos -nomake examples -nomake docs -cocoa -fast -release
- On OS X >= 10.9 add
-platform unsupported/macx-clang-libc++
- On OS X < 10.9, to compile with clang add
-platform unsupported/macx-clang
- If compiling with gcc/g++, make sure that
g++ --version
refers to Apple's gcc >= 4.2 or clang >= 318.0.61 - To use another openssl than the system (mainly for security reasons), add
-openssl-linked -I /usr/local/Cellar/openssl/1.0.2d_1/include -L /usr/local/Cellar/openssl/1.0.2d_1/lib
(where the path is changed to your openssl installation).
Then, compile using:
make
And install (after making sure /opt/qt4
is user-writable) using:
make install
git clone https://github.com/NatronGitHub/Natron.git
cd Natron
If you want to compile the bleeding edge version, use the master branch:
git checkout master
Update the submodules:
git submodule update -i --recursive
In the past, OCIO configs were a submodule, though due to the size of the repository, we have chosen instead to make a tarball release and let you download it here. Place it at the root of Natron source tree:
curl -k -L https://github.com/NatronGitHub/OpenColorIO-Configs/archive/Natron-v2.3.tar.gz | tar zxf -
mv OpenColorIO-Configs-Natron-v2.1 OpenColorIO-Configs
You have to define the locations of the required libraries. This is done by creating a .pri file that will tell the .pro where to find those libraries. The only library to put in the config.pri file on unix systems is boost. For all other libraries are found with PKGConfig.
- create the config.pri file next to the Project.pro file.
You can fill it with the following proposed code to point to the libraries. Of course you need to provide valid paths that are valid on your system.
INCLUDEPATH is the path to the include files
LIBS is the path to the libs
If you installed libraries using MacPorts, use the following config.pri:
# copy and paste the following in a terminal

You can generate a makefile by opening a Terminal, setting the current directory to the toplevel source directory, and typing
qmake -r
then type
make
This will create all binaries in all the subprojects folders.
If you want to build in DEBUG mode change the qmake call to this line:
qmake -r CONFIG+=debug
-
You can also enable logging by adding CONFIG+=log
-
You can also enable clang sanitizer by adding CONFIG+=sanitizer
It is possible to build Natron using clang (version 3.8 is required, version 9.0 is recommended) with OpenMP support on MacPorts (or homebrew for OS X 10.9 or later). OpenMP brings speed improvements in the tracker and in CImg-based plugins.
First, install clang 9.0. On OS X 10.9 and later with MacPorts, simply execute:
sudo port -v install clang-9.0
Or with homebrew:
brew install llvm
On older systems, follow the procedure described in "[https://trac.macports.org/wiki/LibcxxOnOlderSystems](Using libc++ on older system)", and install and set clang-9.0 as the default compiler in the end. Note that we noticed clang 3.9.1 generates wrong code with -Os
when compiling openexr (later clang versions were not checked), so it is safer to also change default configure.optflags {-Os}
to default configure.optflags {-O2}
in /opt/local/libexec/macports/lib/port1.0/portconfigure.tcl
(type sudo nano /opt/local/libexec/macports/lib/port1.0/portconfigure.tcl
to edit it).
The libtool that comes with OS X 10.6 does not work well with clang-generated binaries, and you may have to sudo mv /usr/bin/libtool /usr/bin/libtool.orig; sudo mv /Developer/usr/bin/libtool /Developer/usr/bin/libtool.orig; sudo ln -s /opt/local/bin/libtool /usr/bin/libtool; sudo ln -s /opt/local/bin/libtool /Developer/usr/bin/libtool
Then, configure using the following qmake command on MacPorts:
/opt/local/libexec/qt4/bin/qmake QMAKE_CXX='clang++-mp-9.0 -stdlib=libc++' QMAKE_CC=clang-mp-9.0 QMAKE_OBJECTIVE_CXX='clang++-mp-9.0 -stdlib=libc++' QMAKE_OBJECTIVE_CC='clang-mp-9.0 -stdlib=libc++' QMAKE_LD='clang++-mp-9.0 -stdlib=libc++' -r CONFIG+=openmp CONFIG+=enable-osmesa CONFIG+=enable-cairo
Or on homebrew:
env PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig:/usr/local/opt/cairo/lib/pkgconfig:/usr/local/opt/icu4c/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig:/usr/local/opt/libxml2/lib/pkgconfig qmake -spec macx-xcode CONFIG+=debug CONFIG+=enable-cairo CONFIG+=enable-osmesa CONFIG+=openmp -r QMAKE_CXX='/usr/local/opt/llvm/bin/clang++ -stdlib=libc++' QMAKE_CC=/usr/local/opt/llvm/bin/clang QMAKE_OBJECTIVE_CXX='/usr/local/opt/llvm/bin/clang++ -stdlib=libc++' QMAKE_OBJECTIVE_CC='/usr/local/opt/llvm/bin/clang -stdlib=libc++' QMAKE_LD='/usr/local/opt/llvm/bin/clang++ -stdlib=libc++'
To build the plugins, use the following command-line:
make CXX='clang++-mp-9.0 -stdlib=libc++' OPENMP=1
Or, if you have MangledOSMesa32 installed in OSMESA_PATH
and LLVM installed in LLVM_PATH
(MangledOSMesa32 and LLVM build script is available from https://github.com/devernay/osmesa-install :
OSMESA_PATH=/opt/osmesa
LLVM_PATH=/opt/llvm
make CXX='clang++-mp-9.0 -stdlib=libc++' OPENMP=1 CXXFLAGS_MESA="-DHAVE_OSMESA" LDFLAGS_MESA="-L${OSMESA_PATH}/lib -lMangledOSMesa32 `${LLVM_PATH}/bin/llvm-config --ldflags --libs engine mcjit mcdisassembler | tr '\n' ' '`" OSMESA_PATH="${OSMESA_PATH}"
Follow the instruction of build but add -spec macx-xcode to the qmake call command:
qmake -r -spec macx-xcode
Then open the already provided Project-xcode.xcodeproj and compile the target "all"
The source distributions of the plugin sets openfx-io
and
openfx-misc
contain Xcode projects, but these require setting a few
global variables in Xcode. These variables can be used to switch
between the system-installed version of a package and a custom install
(e.g. if you need to debug something that happens in OpenImageIO).
In Xcode Preferences, select "Locations", then "Source Trees", and add the following variable names/values (Xcode may need to be restarted after setting these):
LOCAL
:/usr/local
on Homebrew,/opt/local
on MacPortsBOOST_PATH
:$(LOCAL)/include
EXR_PATH
:$(LOCAL)
FFMPEG_PATH
:$(LOCAL)
OCIO_PATH
:$(LOCAL)
OIIO_PATH
:$(LOCAL)
OPENCV_PATH
:$(LOCAL)
SEEXPR_PATH
:$(LOCAL)
It is also recommended in Xcode Preferences, select "Locations", then
"Locations", to set the Derived Data location to be Relative, and in
the advanced settings to set the build location to Legacy (if not,
build files are somewhere under ~/Library/Developer/Xcode
.
See instructions under "Using clang-omp with Xcode" at the following page https://clang-omp.github.io
On Macports clang now ships with openmp by default. To install it:
sudo port install clang-9.0
In your config.pri file, add the following lines and change the paths according to your installation of clang
openmp {
INCLUDEPATH += /opt/local/include/libomp
LIBS += -L/opt/local/lib/libomp -liomp5 # may also be -lomp
cc_setting.name = CC
cc_setting.value = /opt/local/bin/clang-mp-9.0
cxx_setting.name = CXX
cxx_setting.value = /opt/local/bin/clang++-mp-9.0 -stdlib=libc++
ld_setting.name = LD
ld_setting.value = /opt/local/bin/clang-mp-9.0
ldplusplus_setting.name = LDPLUSPLUS
ldplusplus_setting.value = /opt/local/bin/clang++-mp-9.0 -stdlib=libc++
QMAKE_MAC_XCODE_SETTINGS += cc_setting cxx_setting ld_setting ldplusplus_setting
QMAKE_LFLAGS += "-B /usr/bin"
}
The qmake call should add CONFIG+=openmp
qmake -r -spec macx-xcode CONFIG+=debug CONFIG+=enable-osmesa LLVM_PATH=/opt/llvm OSMESA_PATH=/opt/osmesa CONFIG+=openmp QMAKE_CXX='clang++-mp-9.0 -stdlib=libc++' QMAKE_CC=clang-mp-9.0 QMAKE_OBJECTIVE_CXX='clang++-mp-9.0 -stdlib=libc++' QMAKE_OBJECTIVE_CC='clang-mp-9.0 -stdlib=libc++' QMAKE_LD='clang++-mp-9.0 -stdlib=libc++' -r CONFIG+=openmp CONFIG+=enable-osmesa CONFIG+=enable-cairo
Then you can just build and run using Xcode
Whenever the .pro files change, Xcode will try to launch qmake and probably fail because it doesn't find the necessary binaries (qmake, moc, pkg-config, python3-config, etc.). In this case, just open a Terminal and relaunch the above command. This will rebuild the Xcode projects.
Alternatively, you can globally add the necessary directories
(/usr/local/bin
on Homebrew, /opt/local/bin
on MacPorts) to you
PATH (see http://www.emacswiki.org/emacs/EmacsApp for instructions).
On MacPorts, this would look like:
launchctl setenv PATH /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin
(cd Tests && qmake -r CONFIG+=debug CONFIG+=coverage && make -j4 && ./Tests)
This is not required as generated files are already in the repository. You would need to run it if you were to extend or modify the Python bindings via the typesystem.xml file. See the documentation of shiboken-2.7 for an explanation of the command line arguments.
On MacPorts:
rm Engine/NatronEngine/* Gui/NatronGui/*

tools/utils/runPostShiboken.sh
Note Shiboken has a few glitches which needs fixing with some sed commands, run tools/utils/runPostShiboken.sh once shiboken is called
Instructions to build the openfx-io and openfx-misc sets of plugins can also be found in the tools/packageOSX.sh script if you are using MacPorts, or in the .travis.yml file in their respective github repositories if you are using homebrew (openfx-misc/.travis.yml, openfx-io/.travis.yml.
You can install TuttleOFX using homebrew:
brew tap homebrew/science homebrew/x11 homebrew/python cbenhagen/video
brew install tuttleofx
Or have a look at the instructions for building on MacPorts as well as precompiled universal binaries.
