From c2033df432af87d0176347858c7d11acfe2ed89f Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 3 Dec 2012 23:04:47 +0100 Subject: build: Include a copy of Nix's libstore and daemon; build it. * configure.ac: Call `AC_USE_SYSTEM_EXTENSIONS', and `GUIX_SYSTEM_TYPE'. 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. --- .gitignore | 10 +++ Makefile.am | 6 ++ config-daemon.ac | 64 ++++++++++++++++++ configure.ac | 15 ++++- daemon.am | 152 ++++++++++++++++++++++++++++++++++++++++++ m4/guix.m4 | 29 ++++++++ nix/.gitignore | 4 ++ nix/boost/.gitignore | 3 + nix/libstore/.gitignore | 3 + nix/libutil/.gitignore | 2 + nix/libutil/gcrypt-hash.cc | 50 ++++++++++++++ nix/libutil/gcrypt-hash.hh | 39 +++++++++++ nix/libutil/md5.h | 35 ++++++++++ nix/libutil/sha1.h | 35 ++++++++++ nix/libutil/sha256.h | 35 ++++++++++ nix/nix-daemon/guix-daemon.cc | 115 ++++++++++++++++++++++++++++++++ nix/nix-daemon/shared.hh | 37 ++++++++++ 17 files changed, 633 insertions(+), 1 deletion(-) create mode 100644 config-daemon.ac create mode 100644 daemon.am create mode 100644 nix/.gitignore create mode 100644 nix/boost/.gitignore create mode 100644 nix/libstore/.gitignore create mode 100644 nix/libutil/.gitignore create mode 100644 nix/libutil/gcrypt-hash.cc create mode 100644 nix/libutil/gcrypt-hash.hh create mode 100644 nix/libutil/md5.h create mode 100644 nix/libutil/sha1.h create mode 100644 nix/libutil/sha256.h create mode 100644 nix/nix-daemon/guix-daemon.cc create mode 100644 nix/nix-daemon/shared.hh diff --git a/.gitignore b/.gitignore index 1fe15621e2..89f0ae797c 100644 --- a/.gitignore +++ b/.gitignore @@ -50,3 +50,13 @@ config.cache /guix-package /guix/config.scm /guix-import +/nix/nix-daemon/nix-daemon.cc +/nix/config.h +/nix/config.h.in +stamp-h[0-9] +/nix/AUTHORS +/nix/COPYING +/libformat.a +/libstore.a +/libutil.a +/guix-daemon diff --git a/Makefile.am b/Makefile.am index 8bb3b55634..7e5be0be2a 100644 --- a/Makefile.am +++ b/Makefile.am @@ -222,6 +222,12 @@ SUBDIRS = po info_TEXINFOS = doc/guix.texi EXTRA_DIST += doc/fdl-1.3.texi +if BUILD_DAEMON + +include daemon.am + +endif BUILD_DAEMON + ACLOCAL_AMFLAGS = -I m4 AM_DISTCHECK_CONFIGURE_FLAGS = \ --with-libgcrypt-prefix="$(LIBGCRYPT_PREFIX)" \ diff --git a/config-daemon.ac b/config-daemon.ac new file mode 100644 index 0000000000..7570814705 --- /dev/null +++ b/config-daemon.ac @@ -0,0 +1,64 @@ +dnl -*- Autoconf -*- fragment for the C++ daemon. + +AC_ARG_ENABLE([daemon], + [AS_HELP_STRING([--enable-daemon], [build the Nix daemon (C++)])], + [guix_build_daemon="$enableval"], + [guix_build_daemon="no"]) + +AC_MSG_CHECKING([whether to build daemon]) +AC_MSG_RESULT([$guix_build_daemon]) + +dnl C++ environment.
