Thanks!! Now it works. Can you explain what happened? It was just a matter of exporting LD_LIBRARY_PATH?. In my .bashrc I had LD_LIBRARY_PATH="$HOME/.linuxbrew/lib:$LD_LIBRARY_PATH" instead of the export, but I thought it was the same.

They're similar, but not exactly the same.

LD_LIBRARY_PATH="$HOME/.linuxbrew/lib:$LD_LIBRARY_PATH"

sets a local shell variable, whereas

export LD_LIBRARY_PATH="$HOME/.linuxbrew/lib:$LD_LIBRARY_PATH"

sets an environment variable. Your confusion is probably caused by your experience with PATH, which is already exported, so you don't need to export it again when you modify it, whereas LD_LIBRARY_PATH was not yet exported.

Cheers,

Yeah, I was used to the PATH experience. Thanks a lot :)

Just in case someone is interested. Previous solved the issue when it is the case that you launch zsh from bash or another running shell, but the error persists when zsh is configured to be the default shell. It is that way because zsh can't be launched as the first shell because it doesn't find its shared libraries because it hasn't yet have time to read .zshrc.

I'm not sure in others distributions, but in debian systems you must add as sudo a file in /etc/ld.so.conf.d/ called for example linuxbrew.conf. For this file it is enough to have a line with the path to the lib directory of your linubrew installation, for example:

/home/user/.linuxbrew/lib

That way, linuxbrew lib directory will be available on startup and the default shell will know about it.

If you want to update the settings before restart, run sudo ldconfig.

I don't know if it would be good to add it to the README, because it is needed for a complete installation of linuxbrew.
