Compile guix from git?

Compile guix from git?

[Claes Wallin (韋嘉誠)]

How do people compile guix directly from git source? I've been
searching around in HACKING and manual.html#Contributing and other
places, the internet in general, and haven't been able to find any
instructions.

It ought to be:

1. Get dependencies manually or with 'guix environment guix'.
2. aclocal
3. automake, maybe automake -a
4. autoconf
5. configure --sharedstatedir=/var --with-libgcrypt-prefix=wherever
6. make

But #3 fails. nix/config.h.in is missing, maybe other things too but
that's where it halts.

What I do now to make it work is I insert:

1.1. tar axf --strip-component=1 /path/to/guix-0.8.2.tar.gz
1.2. git checkout HEAD .
1.3. git clean -fd

Seems to be working, but there must be something everyone else is
doing that I missed in a document somewhere. Or maybe everyone is
working in checkouts made at some point when that file existed?

Documentation has been moved from the 'HACKING' file to the manual in
section "Contributing" recently.  As a consequence, the web manual lacks
some informations since it refers to the current release.

You just need to execute './bootstrap' to generate the configure script.

Oh, ok.

Ah, so simple! I even saw that script there, but didn't read it and
made the wrong assumptions about what it's for. Didn't know about
autoreconf before, it seems there are a few more steps in autotools
than I've seen in other tools. Great that there's a wrapper for them
all.

Thanks for your help!

Replace #2, #3, and #4 with just “autoreconf -vfi”.

For #5, you probably mean --localstatedir, not --sharedstatedir.

Don’t worry, ‘autoreconf’ will do the right thing.  :-)

Alternately, you can also do:

  guix build guix --with-source=/path/to/guix

where the last component of /path/to/guix is literally ‘guix’, and where
/path/to/guix contains a possibly pristine checkout.  But of course,
that command builds from scratch, which may not be what you want.

HTH!

Oh, oops. Lucky I wrote it out explicitly. I'll take another look at
the Contributing chapter, now that I know I need to use the latest git
version.

Yeah, I noticed. The above has worked for most GNU utils and similar
I've ever touched, but guix seems a bit more involved. :-)

Very cool! That takes care of everything, I assume. Environment,
autotools, config params, the works. Good. Build instructions are best
kept in code.

Maybe this route is already mentioned in Contributing. If it isn't, it should!

Sure does!

The best way to access the latest version of the manual from a checkout
is:

  make doc/guix.info
  info -f doc/guix.info

Or you can use Emacs’s Info reader, or you can also generate HTML or
PDF:

  make doc/guix.pdf
  make doc/guix.html
