Re: [Help-gsl] Building GSL

[Dominic Steinitz]

Hi Peter,

Thanks very much for replying.

I think there must be some assumption about where things like autoconf live as 
I had this problem when I installed the build tools via nix but not via 
homebrew (nix-env -i autoconf vs brew install autoconf).

In the end I managed to get nix to build gsl with this in my shell.nix

A bit simpler than the instructions in HACKING I think 😀 - I am leaving it here 
in case anyone else is searching for how to build gsl via nix.

Maybe I should create a PR to add this to the HACKING instructions?
