`make scala` fails to produce full PDF

[mlliarm]

Hello,

I tried building the source on my machine [1], but it's failing with errors. As a result only 5-6 pages are getting printed into PDF.

Please find the build log attached as [2] and the produced PDF as [3].

Any pointers or workarounds would be very welcome.

I'll keep googling to see if I can fix this, and if so I'll post the solution here.

Best regards, Mike

Hello,

Are you using Nix?

Hi,

Thanks for the reply.

Just installed Nix, and I'm getting a different error now when running nix-shell as per instructions:

Installed Nix with sh <(curl -L https://nixos.org/nix/install) --daemon as suggested at the Nix installation site.

Thanks for the fast response !

ps: my shell is bash.

Thx !

Tips:

1. Do nix flake show to print all the available editions
2. Do nix build .#<edition> to build the edition you want.

In you case, it will be: nix build .#ctfp-scala

[drupol]

You might need to enable support of flakes, which might not be enabled by default !

See the relevant section in here: https://nixos.wiki/wiki/Flakes

I might be doing something wrong:

(ctfp-scala) milia@Newton:~/Documents/dev/latex/milewski-ctfp-pdf$ nix build .#ctfp-scala
error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override

(ctfp-scala) milia@Newton:~/Documents/dev/latex/milewski-ctfp-pdf$ nix build .#ctfp-scala --extra-experimental-features nix-build

[drupol]

No, you just need to enable Nix flakes :), see:

[mlliarm]

Thank you very much !

Your suggestion at the previous comment fixed the nix build .#ctfp-scala issue, and now I can see packages getting downloaded.

I'll update this comment once the PDF is built !

It'd be nice & perhaps useful if you could add those steps on the README.md file for future users that encounter the same issue when using Nix to build the book :)

Thanks ! <3

EDIT: took a while on my old laptop, but the 566pgs amazing book of Bartosz was built like a charm !

[drupol]

Indeed, this is something to do ! I will try to focus on this soon !

[mlliarm]

@drupol if you'd like I can write up the missing steps in the README.md and send a PR :)

[drupol]

That would be truly amazing :) thanks !!!
