[Nix-dev] Boost postFixup failing

[Ashley Gillman]

Thanks Zimbatm,
16GB, and I retried with 32GB.

Actually a very good idea with NixOps. I didn't realise you could use your own pre-built stuff, that would really simplify things. As a data scientist I am not so familiar with DevOps but it might be just the solution to get the reproducibility I need. Guess I have my weekend project sorted :)

Cheers,
Ash

For example, when building Python Pillow, I had to also mount an empty directory over /usr/include, because the builds were including gcc flags for `-I/usr/include` and breaking the build. But this shouldn't happen, should it? The hack of mounting over these directories was a temporary fix.
