Add `--with-store-dir' option, and substitute `storedir'. Include `config-daemon.ac'. * config-daemon.ac: New file. * Makefile.am [BUILD_DAEMON]: Include `daemon.am'. * daemon.am: New file. * m4/guix.m4 (GUIX_SYSTEM_TYPE): New macro. * nix/libutil/gcrypt-hash.cc, nix/libutil/gcrypt-hash.hh, nix/libutil/md5.h, nix/libutil/sha1.h, nix/libutil/sha256.h, nix/nix-daemon/guix-daemon.cc, nix/nix-daemon/shared.hh: New files. --- nix/nix-daemon/guix-daemon.cc | 115 ++++++++++++++++++++++++++++++++++++++++++ nix/nix-daemon/shared.hh | 37 ++++++++++++++ 2 files changed, 152 insertions(+) create mode 100644 nix/nix-daemon/guix-daemon.cc create mode 100644 nix/nix-daemon/shared.hh (limited to 'nix/nix-daemon') diff --git a/nix/nix-daemon/guix-daemon.cc b/nix/nix-daemon/guix-daemon.cc new file mode 100644 index 0000000000..43d4113493 --- /dev/null +++ b/nix/nix-daemon/guix-daemon.cc @@ -0,0 +1,115 @@ +/* Guix --- Nix package management from Guile. -*- coding: utf-8 -*- + Copyright (C) 2012 Ludovic Courtès + + This file is part of Guix. + + Guix is free software; you can redistribute it and/or modify it + under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or (at + your option) any later version. + + Guix is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
