Nix uses Sleepycat's Berkeley DB and CWI's ATerm library. However, these
|
|
|
|
|
are fetched automatically as part of the build process.

Other than that, you need a good C++ compiler. GCC 2.95 does not appear

to work; please use GCC 3.x.

|
|
|
the latest revision into a directory called <filename>nix</filename>:

can download a <ulink

To build Nix, do the following:

Currently, the only useful switch for <command>configure</command> is
|
|
|
|
|
<option>--prefix=<replaceable>prefix</replaceable></option> to specify
|
|
|
|
|
where Nix is to be installed. The default installation directory is
|
|
|
|
|
<filename>/nix</filename>. You can change this to any location you like.
|
|
|
|
|
You should ensure that you have write permission to the installation
|
|
|
|
|
prefix.

It is advisable <emphasis>not</emphasis> to change the installation

|
|

prefix, since doing so will in all likelihood make it impossible to use

derivates built on other systems.
