Make sure you have one of the following compilers installed:
|min. MSVC 2015 (We recommend the MSVC 2019 Community Version compiler. During installation, exclude everything except for VC++, Win 10 SDK and ATL support)||min. GCC 5.3.1||min. Clang 3.5|
Qt is the only dependency you will need to install. Go to the Qt download section and download the Qt installer.
Please note that Qt 5.10.0 or higher is needed in order to have full Qt3D support. Qt 6 is supported. Install the Qt version with the minimum of the following features (uncheck all other boxes) to a path without white spaces:
- A compiler for your system (MSVC, gcc, clang)
After the installation is finished make sure to add the Qt bin folder (e.g.
<QtFolder>\5.15.1\msvc2019_64\bin) to your
PATH variable. On Linux and MacOS you might also need to add the Qt lib folder (e.g.
<QtFolder>\5.15.1\msvc2019_64\lib) to the
Clone the fork to your local machine:
git clone https://github.com/<YourGitUserName>/mne-cpp.git
Setup a new remote pointing to MNE-CPP’s main repository:
git remote add upstream https://github.com/mne-tools/mne-cpp.git
Every time you want to update to the newest changes use:
git fetch --all git rebase upstream/main

- Open mne-cpp in QtCreator. To open the project select the top CMakeLists.txt file in the
- The first time you open the project you will be prompted to configure the project with a pre-defined kit. Select the appropriate kit, e.g.,
Desktop Qt 5.15.1 MSVC2019 64bitand configure the project.
- In QtCreator select the Release mode in the lower left corner.
- In the Qt Creator’s Projects window, right mouse click on the top level MNE-CPP tree item and select Run CMake. Wait until the progress bar in lower right corner turns green (this step may take some time).
- Right mouse click again and then hit Build (this step may take some time). Wait until progress bar in lower right corner turns green.
- After the build process is finished, go to the
mne-cpp/out/Releasefolder. All applications and libraries should have been created throughout the build process.
For building on CentOS and other linux distros with older gcc versions, check if RHEL Developer Toolsets are available with newer versions. In Qt Creator, under
Tools > Options > Kits > Compilers, you can add a new compiler, and then add it to your build kit in
Tools > Options > Kits > Kits.
Navigate to the mne-cpp base project folder.
We provide a cross-platform build script to automatically run CMake and build.
For more build options and how to set them, run:
Alternatively, you can manually run:
cmake -B build -S src -DCMAKE_BUILD_TYPE=Release cmake --build build
The building can be parallelized by adding
--parallel n to run n parallel builds when calling, ex.
cmake --build build --parallel 6. This is greatly recommended as it speeds up building and is done for you in the provided build script based on the number of available cores.
Once built, applications can be run from within QtCreator using the run button on the bottom left side. To instead run applications from the command line, navigate to
out/Release/apps and run the program, ex.
You might have to add the folders including the Qt libraries to your OS’s corresponding environment variables. In order to run the examples you must download the MNE-Sample-Data-Set from here and extract the files to
mne-cpp/out/Release/resources/MNE-sample-data. Once finished you can try to run one of the examples, e.g., ex_disp_3D. If the build was successful the example should start and display a window including a 3D brain as well as a source localization result.
