Install neovim with old glibc

Issue: neovim can not load libc.so.6 which requires glibc_2.28 which is higher than installed glibc version.

After asking bing chat and find out that I need to install latest glibc version with sudo which I can’t I decided to clone neovim and compile locally.

glibc is a system level package.

Previsou release that requires higher glibc version

        libutil.so.1 => /lib64/libutil.so.1 (0x00002ae00ff40000)

I installed this release which does not require glibc.2.31 and now I can run it successfully.

It’s too time consuming to build the neovim from scratch.

.config path for neovim to start with different config

by default, Neovim looks for configuration files in the ~/.config/nvim directory. However, when you use the NVIM_APPNAME environment variable, Neovim will look for the configuration in the ~/.config/{NVIM_APPNAME} directory instead.

So, if you set NVIM_APPNAME=lunarvim, Neovim will look for the configuration files in the ~/.config/lunarvim directory. Similarly, if NVIM_APPNAME=nvchad, it will look in the ~/.config/nvchad directory.

This allows you to have multiple separate configurations that you can switch between just by changing the NVIM_APPNAME environment variable. It’s a powerful feature for managing multiple Neovim configurations.

Remember to clone or place your desired configurations into the respective directories under ~/.config/. For example, if you’re using LunarVim and NvChad, you should have ~/.config/lunarvim and ~/.config/nvchad directories, each containing the respective configuration files.

If you want to use the default configuration, you can just run nvim without setting the NVIM_APPNAME environment variable, and it will look for the configuration files in the default ~/.config/nvim directory.

Please note that the ~/.config directory is a standard for user-specific application configuration files on Unix-like operating systems. It’s defined by the XDG Base Directory Specification. If you want to use a different directory, you’ll need to change the XDG_CONFIG_HOME environment variable, which defaults to ~/.config.
