Installing from Source

Hi,
I want to install OpenMC on a new server that does not have internet access. Therefore, I need to download the source code from my computer and transfer it to the server to perform the “make” and “make install” steps. However, when I use “git clone,” I find that the vendor submodule is missing. Even if I download the zip archive directly from the GitHub website, it also lacks the submodule. How can I resolve this issue? Are there any other download methods?
Thanks,
Tianxiang

@Tianxiang From a computer that has internet access, you can run

git clone --recurse-submodules https://github.com/openmc-dev/openmc.git

and then use zip or tar to create an archive that can be transferred to your machine without internet access. Good luck!

@paulromano Thank you very much, but I have encountered an issue. Do I need to update the GNU compiler?
