Installing gsplat on Windows

Follow these steps to install gsplat on Windows.

Prerequisites

1. Install Visual Studio Build Tools. If MSVC 143 does not work, you may also need to install MSVC 142 for Visual Studio 2019. And your CUDA environment should be set up properly.

2. Activate your conda environment:

   conda activate <your_conda_environment>

   Replace <your_conda_environment> with the name of your conda environment. For example:

   conda activate gsplat

3. Activate your Visual C++ environment: Navigate to the directory where vcvars64.bat is located. This path might vary depending on your installation. A common path is:

   C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build
   

4. Run the following command:

   ./vcvars64.bat

   If the above command does not work, try activating an older version of VC:

   ./vcvarsall.bat x64 -vcvars_ver=<your_VC++_compiler_toolset_version>

   Replace <your_VC++_compiler_toolset_version> with the version of your VC++ compiler toolset. The version number should appear in the same folder.

   For example:

   ./vcvarsall.bat x64 -vcvars_ver=14.29
