Building Stellarium

Hello, and thank you for your interest to Stellarium!

If you want to test a prebuilt beta version, take a look at https://github.com/Stellarium/stellarium-data/releases/tag/weekly-snapshot

Why build from source?

Each time Stellarium is released, the source code is released in Github’s packaging system. Building source code that is released in this way should give you a working copy of Stellarium which is functionally identical to the binaries for that release.

It is also possible to get the source code “in development” using Git. This may contain new features or bugfixes which have been implemented since the last release of Stellarium, so it’s often more fun.

Warning: Git versions of the Stellarium source code are work in progress, and as such may produce an unstable program, may not work at all, or may (rarely) not even compile.

Integrated Development Environment (IDE)

If you plan to develop Stellarium, it is highly recommended to utilize an IDE. You can use any IDE of your choice, but QtCreator is recommended as best suited for Qt development.

Inside QtCreator, you open the CMakeLists.txt inside Stellarium’s source directory. Default settings create a debug build with all useful plugins. In the Projects tab (button in vertical left bar), you should at least configure Debug and Release builds.

Do not forget to load the Code Style File (TAR.GZ) in Extras/Settings/C++/Coding style (Import… button).

Prerequisite Packages

To build and develop Stellarium, several packages may be required from your distribution. Here’s a list.

Required dependencies

Dependencies

Optional dependencies

Optionally bundled dependencies

If these are not found on the system, they are downloaded automatically. See MAINTAINER BUSINESS for details.

Installing these packages

To install all of these, use the following commands:

Fedora / CentOS

Note: This should work on RHEL/CentOS 8 or later and recent versions of Fedora. To build on CentOS 7 or older, see Linux with outdated Qt.

sudo dnf install cmake gcc graphviz doxygen gettext git \
                 qt5-qtbase-devel qt5-qttools-devel qt5-qtscript-devel qt5-qtsvg-devel qt5-qtmultimedia-devel \
                 qt5-qtserialport-devel qt5-qtlocation-devel qt5-qtcharts-devel qt5-qtwebengine-devel

Linux with outdated Qt

Stellarium tracks the recent Qt releases fairly closely and as such many Linux distribution repositories do not contain an up-to-date enough version for building Stellarium. In the case of Ubuntu, the ‘‘backports’’ repository is often good enough, but there may be a need to install it “outside” your package manager. Here’s how.

The Qt development team provides binary installers. If you want to build Qt yourself from source, this is fine but it will take a ‘‘long’’ time. We recommend the following procedure for manually installing the latest Qt (required: 5.9 or above at the moment):

Linux without QtWebEngine

On some distributions (known for ARM systems, like Raspberry OS (Raspbian)) there is no QtWebEngine. The CMake script will check installed qtwebengine5 package and if it is not found emits a warning, but Stellarium will be built without QtWebEngine support. The result is shown in the system web browser.

MacOS

You may using the distribution from the Qt Company to install the latest stable version of Qt. In this case adding Qt to your PATH environment variable will to adding to your ~/.bash_profile (Bash) or ~/.zprofile (Zsh) file the following line (for example we installed Qt 5.12.12):

export PATH=~/Qt/5.12/clang_64/bin:$PATH

MacOS without QtWebEngine

On ARM-based (Apple Silicon) Macs, there is no support for QtWebEngine or it buggy (QtWebEngine in Qt 5.15.2). The CMake script will check installed QtWebEngine libraries and if then is not in system then Stellarium will build without QtWebEngine support. The result is shown in the system web browser.

Windows

After installing all required libraries and tools you should configure the build environment.

Add C:\Qt\Qt5.15.2 to your PATH variable - you should add string C:\Qt\Qt5.15.2\msvc2019;C:\Qt\Qt5.15.2\msvc2019\bin for 32-bit or C:\Qt\Qt5.15.2\msvc2019_64;C:\Qt\Qt5.15.2\msvc2019_64\bin for 64-bit to PATH variable. (Replace the version numbers of Qt and the version of Visual Studio (2017/2019) with the version that you have installed)

ANGLE issues:

Known limitations with Qt 5.15.x:

Note: After changes to the PATH variable you should reboot the computer to apply those changes.

Windows (static)

You can build a static version using MSVC-static kit (for example we installed Qt 5.15.12 with MSVC2019):

To prepare a static kit, prepare src package of Qt 5.15.12, and configure compilation tool (Python, Ruby, Perl and Visual Studio 2019). Enter src folder:

configure.bat -static -prefix "D:\Qt\msvc2019_static" -confirm-license -opensource  -debug-and-release -platform win32-msvc  -nomake examples -nomake tests  -plugin-sql-sqlite -plugin-sql-odbc -qt-zlib -qt-libpng -qt-libjpeg -opengl desktop -mp
nmake
nmake install

When finishing compilation, configure kit in Qt Creator. Clone Kit “Desktop Qt 5.15.12 MSVC” to “Desktop Qt 5.15.12 MSVC (static)”. Then configure CMake Generator with NMake Makefiles JOM + Extra generator: CodeBlocks.

Finally, just open CMakeLists.txt in Qt Creator and build it with MSVC-static kit.

Getting the source code

We recommend using a copy of our git repository to build your own installation as it contains some dependencies required for building.

Extract the tarball or ZIP containing the source code

You can find the source code from

https://github.com/Stellarium/stellarium/releases

Do this command in a terminal (if you prefer, you might use arK or some other graphical archive tool):

$ tar zxf stellarium-0.21.3.tar.gz

You should now have a directory stellarium-0.21.3 with the source code in it.

Clone project from GitHub

To create the copy install git from your OS distribution repository or from https://git-scm.com/.

The git repository has become quite large (about 2GB). You do not need the complete history to build or continue development, but can try a blobless clone (https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/)

$ git clone --filter=blob:none https://github.com/Stellarium/stellarium.git
$ cd stellarium

Else, to get the full repository, execute the following commands:

$ git clone https://github.com/Stellarium/stellarium.git
$ cd stellarium

Download source code from GitHub

You can download fresh source code from GitHub by web.

Windows specifics

On Windows save the file (master.zip or stellarium-0.21.3.tar.gz) to the C:/Devel directory as example. You will need a decompression program installed in Windows, for example 7-Zip. The root of the source tree will be C:/Devel/stellarium for simplicity.

Building

Assuming you have collected all the necessary libraries, here’s what you need to do to build and run Stellarium:

On Linux

$ mkdir -p build/unix
$ cd build/unix
$ cmake -DCMAKE_INSTALL_PREFIX=/opt/stellarium ../.. 
$ make -jN

On macOS

$ mkdir -p build/macosx
$ cd build/macosx
$ cmake ../.. 
$ make -jN

On Windows

$ md build
$ cd build
$ md msvc
$ cd msvc
$ cmake -DCMAKE_INSTALL_PREFIX=c:\stellarium-bin -G "Visual Studio 16 2019" ../..
$ cmake --build . --  /maxcpucount:N /nologo

For Visual Studio 2017:

$ cmake -DCMAKE_INSTALL_PREFIX=c:\stellarium-bin -G "Visual Studio 15 2017 Win64" ../..

Instead of N in -j (N in /maxcpucount) pass a number of CPU cores you want to use during a build.

If you have Qt5 installed using official Qt installer, then pass parameter CMAKE_PREFIX_PATH to cmake call used to configure Stellarium, e.g.

$ cmake -DCMAKE_PREFIX_PATH=/opt/Qt5 ../..

When you are using QtCreator IDE, build directories are created by the IDE. It appears that on Windows, a directory name is proposed, but you have to create it manually.

You can keep your copy up-to-date by typing git pull --rebase in ~/stellarium. Feel free to send patches to our mailing list stellarium@googlegroups.com

Test-run compiled program without installing

After compilation, you may run the program when you are in the right directory.

Linux

Assuming the stellarium sources are in DEV/stellarium and build in DEV/stellarium/build/unix

cd DEV/stellarium
./build/unix/src/stellarium

Windows

Most users will work with QtCreator which sets its own paths for debug and release builds. Running with the designated buttons (green arrow) from inside QtCreator should work. You can also create a link for the executable in the src subdirectory of the build directory. Move this link to the source directory and edit its properties to run inside the source directory. Then you can double-click this link, or even place it in your task bar.

Code testing

There are several test programs in the repository. To build them, define -DENABLE_TESTING=ON (or -DENABLE_TESTING=1), or configure cmake in QtCreator’s Projects tab.

Then configure a Debug build and select a test… application to be executed.

Please try to test your changes before committing to master. Our automated GitHub Actions and AppVeyor builds will signal failure when tests don’t complete.

To execute all unit tests in terminal please run:

$ make test

or

$ ctest --output-on-failure

Packaging

OK, you have built the program from source code and now you may want to install the executable file into your operating system or create a package for distribution.

To install the executable file (with necessary libraries and data files) into the directory defined in parameter CMAKE_INSTALL_PREFIX, run:

$ sudo make install

Linux specifics

To create a source package (TGZ) on linux you need run:

$ make package_source

To create a binary package (TGZ) on linux you need run:

$ make package

After building of TGZ binary package you may create a DEB or RPM package also:

$ cpack -G DEB

or

$ cpack -G RPM

macOS specifics

IMPORTANT: you should delete or move aside the old Stellarium.app before each new build:

$ rm -r Stellarium.app

Then build the macOS application:

$ make install

You’ll find now an application Stellarium.app with the correct icon in the build directory.

On ARM-based (Apple Silicon) Macs, ARM application need to be code signed. To sign the application with an ad-hoc signature:

codesign --force --deep -s - Stellarium.app

To create the DMG file (Apple Disk Image) run:

$ mkdir Stellarium
$ cp -r Stellarium.app Stellarium
$ hdiutil create -format UDZO -srcfolder Stellarium Stellarium.dmg

Windows specifics

To create a Windows installer you need to have installed Inno Setup.

If you have followed all the above procedures the current build will generate the necessary stellarium.iss file in C:\Devel\stellarium\builds\msvc.

Double click on it, then from the menu bar “build-compile”. It will build the stellarium installer package and place it in a folder of the stellarium source tree root folder installers. So you can find it in C:\Devel\stellarium\stellarium\installers

Or you can use cmake command for create an installer:

$ cmake --build c:\devel\stellarium\build\msvc --target stellarium-installer

Supported make targets

Make groups various tasks as “targets”. Starting make without any arguments causes make to build the default target - in our case, building Stellarium, its tests, the localization files, etc. Target | Description —————–|—————————————————————————————————- | install | Installation of all binaries and related files to the directory determined by CMAKE_INSTALL_PREFIX | test | Launch the suite of test executables | apidoc | Generate an API documentation | package_source | Create a source package for distributions | package | Create a binary packages for distributions on linux/UNIX | installer | Create a binary packages for distributions on Windows

Thanks!
