The easiest way to obtain Nix is to download a <ulink
|
|
url='http://www.cs.uu.nl/groups/ST/Trace/Nix'>source
|
|
distribution</ulink>. RPMs for SuSE and Red Hat are also
|
|
available. These distributions are generated automatically.
|
|
</para>
|
|
|
|
<para>
|
|
Alternatively, the most recent sources of Nix can be obtained from its
|
|
<ulink url='https://svn.cs.uu.nl:12443/repos/trace/nix/trunk'>Subversion
|
|
repository</ulink>. For example, the following command will check out
|
|
the latest revision into a directory called <filename>nix</filename>:
|
|
</para>
|
|
|
|
<screen>
|
|
$ svn checkout https://svn.cs.uu.nl:12443/repos/trace/nix/trunk nix</screen>
|
|
|
|
<para>
|
|
Likewise, specific releases can be obtained from the <ulink
|
|
url='https://svn.cs.uu.nl:12443/repos/trace/nix/tags'>tags
|
|
directory</ulink> of the repository. If you don't have Subversion, you
|
|
can also download an automatically generated <ulink
|
|
url='https://svn.cs.uu.nl:12443/dist/trace/'>compressed
|
|
tar-file</ulink> of the head revision of the trunk.

<title>Prerequisites</title>

|

<para>
|
|
The following prerequisites only apply when you build from
|
|
source. Binary releases (e.g., RPMs) have no prerequisites.
|
|
</para>
|
|
|
|
<para>
|
|
A fairly recent version of GCC/G++ is required. Version 2.95
|
|
and higher should work.
|
|
</para>
|
|
|
|
<para>
|
|
To build this manual and the man-pages you need the
|
|
<command>xmllint</command> and <command>xsltproc</command>
|
|
programs, which are part of the <literal>libxml2</literal> and
|
|
<literal>libxslt</literal> packages, respectively. You also
|
|
need the <ulink
|
|
url='http://docbook.sourceforge.net/projects/xsl/'>DocBook XSL
|
|
stylesheets</ulink> and optionally the <ulink
|
|
url='http://www.oasis-open.org/docbook/xml/4.2/docbook-xml-4.2.zip'>
|
|
DocBook XML 4.2 DTD</ulink>. Note that these are only required
|
|
if you modify the manual sources or when you are building from
|
|
the Subversion repository.
|
|
</para>
|
|
|
|
<para>
|
|
To build the parser, very <emphasis>recent</emphasis> versions
|
|
of Bison and Flex are required. (This is because Nix needs GLR
|
|
support in Bison and reentrancy support in Flex.) For Bison,
|
|
you need version 1.875c or higher (1.875 does
|
|
<emphasis>not</emphasis> work), which can be obtained from the
|
|
<ulink url='ftp://alpha.gnu.org/pub/gnu/bison'>GNU FTP
|
|
server</ulink>. For Flex, you need version 2.5.31, which is
|
|
available on <ulink
|
|
url='http://lex.sourceforge.net/'>SourceForge</ulink>. Slightly
|
|
older versions may also work, but ancient versions like the
|
|
ubiquitous 2.5.4a won't. Note that these are only required if
|
|
you modify the parser or when you are building from the
|
|
Subversion repository.

Nix uses Sleepycat's Berkeley DB and CWI's ATerm library. These
|
|
are included in the Nix source distribution. If you build from
|
|
the Subversion repository, you must download them yourself and
|
|
place them in the <filename>externals/</filename> directory.
|
|
See <filename>externals/Makefile.am</filename> for the precise
|
|
URLs of these packages.

<title>Building Nix from source</title>

<para>
|

After unpacking or checking out the Nix sources, issue the following
|
|
commands:
|
|
</para>
|
|
|
|
<screen>
|
|
$ ./configure <replaceable>options...</replaceable>
|
|
$ make
|
|
$ make install</screen>
|
|
|
|
<para>
|
|
When building from the Subversion repository, these should be preceded by
|
|
the command:
|
|
</para>
|
|
|
|
<screen>
|
|
$ autoreconf -i</screen>
|
|
|
|
<para>
|
|
The installation path can be specified by passing the
|
|
<option>--prefix=<replaceable>prefix</replaceable></option> to
|
|
<command>configure</command>. The default installation directory is
|
|
<filename>/nix</filename>. You can change this to any location you like.
|
|
You must have write permission to the <replaceable>prefix</replaceable>
|
|
path.
|
|
</para>
|
|
|
|
<warning>
|
|
<para>
|
|
It is advisable <emphasis>not</emphasis> to change the installation
|
|
prefix from its default, since doing so will in all likelihood make it
|
|
impossible to use derivations built on other systems.
|
|
</para>
|

</warning>
|

<para>

If you want to rebuilt the documentation, pass the full path to the
|
|
DocBook XML catalog file (<filename>docbook.cat</filename>) and to the
|
|
DocBook XSL stylesheets using the
|
|
<option>--with-docbook-catalog=<replaceable>path</replaceable></option>
|
|
and <option>--with-docbook-xsl=<replaceable>path</replaceable></option>
|
|
options.

<title>Installing from RPMs</title>
|
|
|
|
<para>
|
|
RPM packages of Nix can be downloaded from <ulink
|
|
url='http://www.cs.uu.nl/groups/ST/Trace/Nix' />. These RPMs
|
|
should work for most fairly recent releases of SuSE and Red Hat
|
|
Linux. They have been known to work work on SuSE Linux 8.1 and
|
|
9.0, and Red Hat 9.0. In fact, it should work on any RPM-based
|
|
Linux distribution based on <literal>glibc</literal> 2.3 or
|
|
later.
|
|
</para>
|
|
|
|
<para>
|
|
Once downloaded, the RPMs can be installed or upgraded using
|
|
<command>rpm -U</command>. For example,
|
|
</para>
|
|
|
|
<screen>
|
|
rpm -U nix-0.5pre664-1.i386.rpm</screen>
|
|
|
|
<para>
|
|
The RPMs install into the directory <filename>/nix</filename>.
|
|
Nix can be uninstalled using <command>rpm -e nix</command>.
|
|
After this it will be necessary to manually remove the Nix store
|
|
and other auxiliary data:
|
|
</para>
|
|
|
|
<screen>
|
|
rm -rf /nix/store
|
|
rm -rf /nix/var</screen>
|
|
|
|
</sect1>
|
|
|
|
<sect1>
|
|
<title>Permissions</title>
|
|
|
|
<para>
|
|
All Nix operations must be performed under the user ID that owns
|
|
the Nix store and database
|
|
(<filename><replaceable>prefix</replaceable>/store</filename>
|
|
and
|
|
<filename><replaceable>prefix</replaceable>/var/nix/db</filename>,
|
|
respectively). When installed from the RPM packages, these
|
|
directories are owned by <systemitem
|
|
class='username'>root</systemitem>.
|
|
</para>
|
|
|
|
</sect1>
|
|
|
|
<sect1>
|
|
<title>Using Nix</title>
|
|
|
|
<para>
|
|
To use Nix, some environment variables should be set. In
|
|
particular, <envar>PATH</envar> should contain the directories
|
|
<filename><replaceable>prefix</replaceable>/bin</filename> and
|
|
<filename>~/.nix-profile/bin</filename>. The first directory
|
|
contains the Nix tools themselves, while
|
|
<filename>~/.nix-profile</filename> is a symbolic link to the
|
|
current <emphasis>user environment</emphasis> (an automatically
|
|
generated package consisting of symlinks to installed packages).
|
|
The simplest way to set the required environment variables is to
|
|
include the file
|
|
<filename><replaceable>prefix</replaceable>/etc/profile.d/nix.sh</filename>
|
|
in your <filename>~/.bashrc</filename> (or similar), like this:
|
|
</para>
|
|
|
|
<screen>
|
|
. <replaceable>prefix</replaceable>/etc/profile.d/nix.sh</screen>
