MacOS

This page details instructions for compiling RawTherapee on macOS systems. There are also separate pages with instructions for compiling on Linux and Windows. This guide details the what and how parts of compilation. For the why and explanations of these commands, for a list of dependencies, CMake options and other information, please refer to the detailed Linux article.

When in doubt, join us on IRC and ask a human!

For instructions on cloning the source, choosing branches, configuring CMake and doing the actual compilation, see these sections in the Linux guide. The information below is in addition to that.

Dependencies

See the list of dependencies in the Compiling in Linux article.

Additionally, you need these:

• XCode Development Tools. You only need a subset of these, but it is probably easier to just install all of them.
• MacPorts
• Git

Install Git:

sudo port install git

• Configure variants.conf

Add the following line to /opt/local/etc/macports/variants.conf:

+no_gnome +no_x11 +quartz -x11

• Dependencies

To install the dependencies, run:

sudo port install cairo clang-3.7 +openmp cmake fftw-3-single gdk-pixbuf2 gtk2 gtk-engines2 gtkmm gtk-osx-application-gtk2 lcms2 libiptcdata libsigcxx2 pango

We recommend using the latest stable version of the Clang compiler with OpenMP support. Unstable versions are not recommended. The line above includes it.

libiconv patch

libiconv.2.dylib must be patched, otherwise RawTherapee will crash on startup. The patch is available in `tools/osx/libiconv_1.14_rt.patch`

libiconv patching and compilation instructions:

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar xf libiconv-1.14.tar.gz
cd libiconv-1.14
wget https://raw.githubusercontent.com/Beep6581/RawTherapee/dev/tools/osx/libiconv_1.14_rt.patch
patch -p1 < libiconv_1.14_rt.patch
mkdir build
cd build
buildDir="$(pwd)"
../configure --prefix=/opt/local --disable-static 'CFLAGS=-arch x86_64 -mmacosx-version-min=10.5' 'LDFLAGS=-arch x86_64 -mmacosx-version-min=10.5' CXXFLAGS="-arch x86_64 -mmacosx-version-min=10.5"
make
make DESTDIR="$buildDir" install
cd /opt/local/lib
sudo cp ./libiconv.2.dylib ./libiconv.2.dylib.backup # backup MacPorts dylib
sudo cp "${buildDir}/opt/local/lib/libiconv.2.dylib" /opt/local/lib/libiconv.2.dylib

Compiling

See the Compiling in Linux article for instructions on how to clone the source code, choose a branch and how to configure CMake. Ignore the "Now you are ready to compile" code on that page and follow the code on this page.

If you want to upload a build or otherwise share it with others, you must use

-DPROC_TARGET_NUMBER="1"

and set the processor label manually by setting

-DPROC_LABEL="generic processor"

If you want to compile for yourself only, then use

-DPROC_TARGET_NUMBER="2"

and then the processor label would be irrelevant, you could skip it.

Compile RawTherapee

Now you are ready to compile:

cd ~/repo-rt
rm -rf build
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE="release" \
      -DPROC_TARGET_NUMBER="1" \
      -DPROC_LABEL="generic processor" \
      -DCACHE_NAME_SUFFIX="5-dev" \
      -DCMAKE_C_COMPILER="clang-mp-3.7" \
      -DCMAKE_CXX_COMPILER="clang++-mp-3.7" \
      -DCMAKE_CXX_FLAGS="-w" \
      ..
make -j8 install
make macosx_bundle

Run and Share RawTherapee

You will find a disk image in the build directory; this is the distribution release and can be run on any machine which meets the architecture requirements you specified in variants.conf earlier.

To provide the RawTherapee project with your build, please zip the .dmg and AboutThisBuild.txt files together. Name the zip file according to this template:

RawTherapee_OSX_<minimum supported macOS version>_64_<RawTherapee version>.zip

for example if your build is made for macOS 10.12 and the version of RawTherapee is 5.1-dev-g1a2b3c4d, name it:

RawTherapee_OSX_10.12_64_5.1-dev-g1a2b3c4d.zip

Upload the zip archive to http://filebin.net/ and open a new issue on our GitHub page with the link so that we can upload it to the website.
