The NVIDIA CUDA library is needed to build and run any plug-ins that run on the GPU. If you get build errors that have the word "Ninja" in various places, you missed the previous step changing the Generator to "NMake Makefiles". You should then be able to compile and run it by clicking the play icon in the upper right hand corner of the CLion window. Right-click on the CMakeLists.txt file in that directory and select "Load CMake Project". In the left "Project" pane (main CLion window), expand the "samples" folder, and the subdirectory called "context\_selftest". You can test by building the context_selftest project in the "samples" directory. That should be all that is needed to build basic programs that do not require CUDA. If you do not get the green check boxes and a successful auto-detection as shown below, there is a good chance that you did not install Visual Studio correctly, and you missed the step to enable C++ tools. Note that this will likely not be an option in the drop-down menu, but you can just type it in. We then want to change the "Architecture" to "圆4" to build in 64-bit mode. It is recommended to remove this toolchain by clicking on it and then the '-' button. It may also detect and use MinGW as the default toolchain. If it doesn't, click the "+" icon and click on "Visual Studio". With any luck, it should automatically add and detect Microsoft Visual Studio. It may automatically open up a new project wizard, but you can also do it yourself by going to File->Settings, then in the left pane, go to "Build, Execution, Deployment->Toolchains". The next step is to set up the Microsoft Visual Studio C++ compiler in CLion. This should give you a fresh copy of Helios within CLion with the README file displayed. Then, type in the URL for the Helios GitHub repository "", select the directory where you'd like the Helios source code to be located, and hit "Clone". You may need to install Git, which can be done by simply clicking the button to download and install. By default, it should bring up Git as the default version control system. You can have it automatically pull the Helios code from GitHub by clicking on the icon labeled "from VCS". When you open CLion, it will prompt you to open a project. Refer to the documentation page Using the CLion IDE with Helios for information on how to get a free education license. It is recommended for PC that you download and install the CLion IDE, found here. When the installer finishes, there is no need to actually open Visual Studio, and you can move on to the next step. The figure below shows the check box to enable. The important step is to be sure to install the optional packages for C++ Desktop Development. Once you have successfully downloaded the EXE install file, you can run it to perform the install. For more information on choosing your compiler version, consult this page. Once you have reached the downloads page, Download Visual Studio Community 2019. It will require that you join the free Dev Essentials program in order to access the old downloads. The link to download older versions of Visual Studio is here. If your compute capability is less than 5, you'll need to download Visual Studio Community 2019 and CUDA 10.2 to ensure compatibility. You can look up your GPU's compute capability here. Install Microsoft Visual Studio C++ compiler toolsĭownload and install Microsoft Visual Studio Community 2022 if your GPU has compute capability of 5 or higher. On Linux and Mac, you can also use any text editor and the command line to run Helios, which is covered in the documentation. Other IDEs can also be used, such as Microsoft Visual Studio, but setup with Helios is not well documented or tested. There is a separate documentation page showing how to set up Helios in CLion once you have it installed: Using the CLion IDE with Helios. We especially recommend CLion if working on a PC, as it makes setup very easy. CLion is also free to use for educational purposes. CLion is a rich-featured C++ IDE that integrates with the Helios documentation, GitHub, and allows you to do pretty much everything you need based on the graphical interface. If using an IDE, we recommend CLion by JetBrains. Using an IDE for Helios programming can make development easier, particularly if you have minimal command-line experience. Using an Interactive Development Environment (IDE) This page will guide you through installation and set-up of dependent software needed to build and run Helios-based programs.
