Build error

[janbaudisch]

When building nix, I get the following error. Since I have no idea what it actually means, I am just posting it here, hoping someone can explain it...

  GEN    doc/manual/manual.is-valid
I/O error : Attempt to load network entity http://docbook.org/xml/5.0/rng/docbook.rng
warning: failed to load external entity "http://docbook.org/xml/5.0/rng/docbook.rng"

What steps did you take to build Nix?

[janbaudisch]

@domenkozar I installed

• autoconf
• automake
• pkgconfig
• xzutils
• libseccomp
• sqlite
• perl and the modules
• bdwgc
• bison
• flex
• docbook

Then I did:

./bootstrap.sh
./configure
make

...and at make it failed.

System is a Chromebook.

You would also need to install package docbook-xsl and point xsltproc at it, using the --nonet flag (see https://github.com/NixOS/nix/pull/1430)
