Unable to install Felix using Nix

[Sod-Almighty]

I installed Nix, then followed your instructions...

git clone https://github.com/felix-lang/felix.git
cd felix
nix-shell shell.nix

...and got an error...

error: undefined variable 'python36Full'

       at /tmp/felix/shell.nix:19:5:

           18|     ocaml-ng.ocamlPackages_4_06.ocaml

             |     ^
           20|     SDL2
(use '--show-trace' to show detailed location information)

I am confused.

My environment:

# uname -a; cat /etc/issue
Linux nas 4.9.0-11-amd64 #1 SMP Debian 4.9.189-3+deb9u2 (2019-11-11) x86_64 GNU/Linux
Debian GNU/Linux 9 \n \l

On this I can't help. I didn't add the nix build instructions and know very little about nix (I did use it once on a job). But I run MacOS.

BTW: the website is up and down. However .. you don't need it! Felix automatically builds you a personal webserver:

FLX WEB!!! listening on port 1234

The lines are showing plugins being loaded by the core webserver. Then the webserver is running so now you can grab your browser and http://localhost:1234 and you should see the Felix home page. If it is set up correctly you can browse you whole machine (so take care). It's probably best finally to launch it at startup time in an account with suitably restricted access.

If the setup is right you can browse all the Felix sources, library, tutorials and documentation. The main feature is hyperlinked include "felix" and #include "stuff.hpp" in Felix and C++ code, respectively. With any luck you can browse right into your system library headers.

Felix *.fdoc files in src/packages are specifically design as literate programming files so that the Felix webserver can display them nicely. The library document contains the source code, rather than code containing comments. flx can execute these files directly as well.
