Windows

Follow the instructions on this page to compile RawTherapee on Windows using the MSYS2 build environment. For more details on customizing and understanding the build process, see the Linux article.

Note: this guide applies to compiling the 64-bit version of RawTherapee under Windows 7 and newer. Compiling the 32-bit version is no longer supported, nor is compilation on older operating systems. The latest version of RawTherapee to work under 32-bit Windows XP is 5.0-rc1, and can be downloaded here (dated 2017-02-02).

Note that RawTherapee also requires the availability of GTK+ 3.22.24 or newer to have native window support. Without it RawTherapee may exhibit strange behavior, such as maximizing underneath the taskbar in Windows 10. When using an up to date build environment, you should not encounter this problem.

MSYS2 Installation

Install MSYS2 base system

Install the build environment MSYS2 carefully by following the instructions from the MSYS2 website. Make sure to update the system fully until no further updates are available, using the command:

$ pacman -Syu

MSYS2 provides three 'shells' (command-line interfaces) for different purposes: MSYS, MinGW 32-bit and MinGW 64-bit. They can be launched through shortcuts in your Start menu. Most commonly you will be running a 64-bit operating system and will want to create applications that are optimized for that. Therefore, start the MSYS2 MinGW 64-bit shell and continue below.

Note: in following text, <MSYS2> refers to the MSYS2 installation folder, typically C:\msys64

Install tools and libraries

MSYS2 uses the package manager pacman to install software and components. Please refer to the pacman manual for details.

First, install a few miscellaneous tools:

$ pacman -S tar gzip nano make diffutils intltool git

Then install the necessary development tools and the required libraries:

$ pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-gdb mingw-w64-x86_64-make mingw-w64-x86_64-pkg-config mingw-w64-x86_64-cmake mingw-w64-x86_64-ninja mingw-w64-x86_64-gtkmm3 mingw-w64-x86_64-lcms2 mingw-w64-x86_64-fftw mingw-w64-x86_64-lensfun mingw-w64-x86_64-libiptcdata

Note: the mingw-w64-x86_64-libiptcdata package has been added to MSYS2 in December 2020. If you experience difficulty using this package, please see the instructions below how to compile the library yourself.

Updating Lensfun database

RawTherapee uses the Lensfun library for lens-specific corrections. Run the following command to update the database:

$ lensfun-update-data

The updater returns the path where the updated database is located. Copy this path for later use!

Download and build libiptcdata

Since December 2020 the libiptcdata library is provided by MSYS2 and no longer requires manual compilation. Only if you experience problems using this library, follow the instructions below to manually build it. Otherwise, continue to the next section.

$ cd ~
$ curl -LO http://downloads.sourceforge.net/project/libiptcdata/libiptcdata/1.0.4/libiptcdata-1.0.4.tar.gz
$ tar xzf libiptcdata-1.0.4.tar.gz
$ cd libiptcdata-1.0.4
$ ./configure --prefix=/mingw64

Some modifications to the resulting Makefile are needed. You can edit the file with any text editor (either through your OS or from within the shell). We use the nano editor from within the shell:

$ nano Makefile

# search (command Ctrl+W)
DIST_SUBDIRS = m4 libiptcdata po iptc docs win python
# and replace with
DIST_SUBDIRS = m4 libiptcdata po win python

# search
SUBDIRS = m4 libiptcdata po iptc docs win $(MAYBE_PYTHONLIB)
# and replace with
SUBDIRS = m4 libiptcdata po win $(MAYBE_PYTHONLIB)

# save and quit
Ctrl+X, Y

Finally build and install the library:

$ make install

Clone and build RawTherapee

Clone RawTherapee's git repository.

RawTherapee's source code can be cloned from the official GitHub repository:

$ cd ~
$ git clone git://github.com/Beep6581/RawTherapee.git
$ cd RawTherapee

Switching branches

After cloning you will automatically have checked out the dev branch. This is the main development branch of RawTherapee and probably what you want to use. To switch to a different branch, do the following:

$ git checkout branchname # replace with another available branch name

Create a separate directory for the build

It is essential to create a new directory to build the application. The directory can have any name, for example:

$ mkdir build
$ cd build

Note: if you switch branches, always build in an empty directory to prevent issues. From within a build directory, you can run rm -rf * to remove all files.

Configuration and compilation

To create an optimized build for your machine architecture, use the following commands:

$ cmake -G "Ninja" -DLENSFUNDBDIR=put/your/lensfun/directory/here -DCMAKE_BUILD_TYPE="release" -DPROC_TARGET_NUMBER="2" -DCACHE_NAME_SUFFIX="5-dev" ..
$ cmake --build . --target install

Make sure to replace the path to the Lensfun database with the actual path obtained a few steps before. See the Linux article for more details on the various options. Depending on your system, the build process may take anywhere between 5 and 25 minutes.

There may be warnings during the build process which you can safely ignore. Errors that are not traceable to a mistake when following this guide should be reported here.

Starting RawTherapee

RawTherapee can now be run:

$ ./release/rawtherapee.exe # replace release with debug or relwithdebinfo if you built another target

Optional: preloaded CMake cache

As described in the CMake manual

-C <initial-cache>

    Pre-load a script to populate the cache.

    When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project. This option may be used to specify a file from which to load cache entries before the first pass through the project’s cmake listfiles. The loaded entries take priority over the project’s default values. The given file should be a CMake script containing SET commands that use the CACHE option, not a cache-format file.

To simplify the invocation of CMake and be able to easily define Windows specific options, a win.cmake template script is provided with the sources. Copy it out of RawTherapee's source to avoid overwriting by update for instance in mywin.cmake. Edit it to define or modify options. To preload the cache, in the CMake command line:

$ cmake -G "Ninja" -DLENSFUNDBDIR=share/lensfun -DCMAKE_BUILD_TYPE="release" -DPROC_TARGET_NUMBER="2" -DCACHE_NAME_SUFFIX="5-dev" -C <path/to/mywin.cmake> ..

Making a bundled build

This section only applies if you want to run RawTherapee outside the MinGW shell or distribute it.

Note: You can copy either with the Windows file manager or, recommended, with robocopy inside the mingw64 shell script using - instead of / for the options.

Definition of folders

  • <prefix> is <MSYS2>\mingw64,
  • <MSYS2> is the MSYS2 installation folder,
  • and . is the RawTherapee installation folder.

Copy RawTherapee executable and generated files

Create in .\share\gtk-3.0 a file settings.ini containing :

[Settings] gtk-button-images=1


Creating a distributable package

If you plan to distribute RawTherapee packages for the Windows platform, as a first step you need to make sure that RawTherapee will be built for the "generic" processor target. To do so, use -DPROC_TARGET_NUMBER="1" in the CMake command.

During compilation, a script named WindowsInnoSetup.iss is created in the RawTherapee installation folder. This script is used by Inno Setup [1], a program which is used to generate installers for Windows programs. It is advised to download the Unicode version [2] to avoid problems with some languages.

To help users write useful bug reports, package maintainers are encouraged to produce builds which include both a "release" and a "debug" executable, and to bundle them together with the GDB debugger executable.

In other words, put the rawtherapee.exe (release) file together with the rawtherapee-debug.exe (debug) file and the gdb.exe file together into the same installer or the same archive. An alternative is to produce "relwithdebinfo" builds - these are much faster than "debug" but not as optimized as "release" builds, yet they provide just about as much useful information as "debug" builds.

When making "relwithdebinfo" or "debug" builds you must provide the GDB debugger executable. Windows binaries of the debugger gdb.exe can be downloaded from here in 32- and 64-bit versions and will be copied into Rawtherapee installation folder.

Now that everything is set up, to create the package right-click on the WindowsInnoSetup.iss script and choose Compile from the context menu. It will automatically generate the installer and place it in the parent folder.

To make your new package compatible with the RawTherapee website's upload panel, create a zip archive in which you will place both the newly created installer and the corresponding AboutThisBuild.txt file which can be found at the same place. Name the resulting zip archive following this template: RawTherapee_<version>_WinVista_64_<buildtype>.zip

If you are building and distributing nightly builds, follow this template: RawTherapee_<branch>_<version>_WinVista_64_<buildtype>.zip

  • "WinVista" means it can run on any version of Windows from Vista upwards, including 10.
  • The "version" will either look like 5.8 if you checkout the 5.8 tag, or 5.8-g35abd92

if you checkout the dev branch after 5.8 was tagged.

  • If you are shipping more than one build type in an installer, don't include <buildtype> in the name.
