If your R package build is failing on Windows machines (such as AppVeyor) due to a missing GSL (GNU Scientific Library) dependency, you can follow these steps to resolve the issue:

  1. Install GSL on Windows:

    • Download the GSL library installer for Windows from the GSL website (https://www.gnu.org/software/gsl/).
    • Run the installer and follow the installation instructions to install GSL on your Windows machine.

  2. Specify GSL Library Path:

    • Open your R package's project file (.Rproj) or the relevant configuration file (such as DESCRIPTION or configure).
    • Add an environment variable to specify the path to the GSL library. For example, you can add the following line to your .Rproj file or the relevant configuration file:
      arduino
      Sys.setenv(LIB_GSL = "C:/path/to/gsl/library")
      Replace "C:/path/to/gsl/library" with the actual path where GSL is installed on your Windows machine.

  3. Build and Test the Package:

    • Trigger the package build process, either locally or on the Windows machines (e.g., AppVeyor).
    • The build process should now be able to find the GSL library and successfully compile and link the required code.

By installing GSL on your Windows machine, specifying the GSL library path, and ensuring that the build environment recognizes the location of the GSL library, you should be able to resolve the missing GSL dependency issue during the R package build on Windows machines.

It's worth noting that the specific steps and configuration may vary depending on your R package's build system and setup. Consult the documentation for your specific build system or CI platform for more details on configuring library dependencies for Windows builds.
