Dear Gromacs Users,

I have Gromacs version 2022 on my computer. I want to install the 2024 version along with the 2022 version. How can I install it on a different path? The default path is /usr/local/ **gromacs** /bin/GMXRC but I want to have the newer version in this path: /usr/local/ **gromacs-2024** /bin/GMXRC.

Thanks

Hi!

Please see [the install guide](https://manual.gromacs.org/documentation/current/install-guide/index.html#non-standard-location):

> GROMACS is installed in the directory to which `CMAKE_INSTALL_PREFIX` points. It may not be the source directory or the build directory. You require write permissions to this directory. Thus, without super-user privileges, `CMAKE_INSTALL_PREFIX` will have to be within your home directory. Even if you do have super-user privileges, you should use them only for the installation phase, and never for configuring, building, or running GROMACS!

So, in your case, you should add `-DCMAKE_INSTALL_PREFIX=/usr/local/gromacs-2024/` flag when calling `cmake`.
