<para>The standard build environment in the Nix Packages collection
|
2013-08-11 10:47:09 +00:00
|
|
|
|
provides an environment for building Unix packages that does a lot of
|
2008-06-19 16:00:37 +00:00
|
|
|
|
common build tasks automatically. In fact, for Unix packages that use
|
|
|
|
|
the standard <literal>./configure; make; make install</literal> build
|
|
|
|
|
interface, you don’t need to write a build script at all; the standard
|
|
|
|
|
environment does everything automatically. If
|
|
|
|
|
<literal>stdenv</literal> doesn’t do what you need automatically, you
|
|
|
|
|
can easily customise or override the various build phases.</para>

|
|
|
<para>To build a package with the standard environment, you use the
|
|
|
|
|
function <varname>stdenv.mkDerivation</varname>, instead of the
|
|
|
|
|
primitive built-in function <varname>derivation</varname>, e.g.
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
stdenv.mkDerivation {
|
|
|
|
|
name = "libfoo-1.2.3";
|
|
|
|
|
src = fetchurl {
|
|
|
|
|
url = http://example.org/libfoo-1.2.3.tar.bz2;
|
|
|
|
|
md5 = "e1ec107956b6ddcb0b8b0679367e9ac9";
|
|
|
|
|
};
|
|
|
|
|
}</programlisting>
|
|
|
|
|
|
|
|
|
|
(<varname>stdenv</varname> needs to be in scope, so if you write this
|
|
|
|
|
in a separate Nix expression from
|
|
|
|
|
<filename>pkgs/all-packages.nix</filename>, you need to pass it as a
|
|
|
|
|
function argument.) Specifying a <varname>name</varname> and a
|
|
|
|
|
<varname>src</varname> is the absolute minimum you need to do. Many
|
|
|
|
|
packages have dependencies that are not provided in the standard
|
|
|
|
|
environment. It’s usually sufficient to specify those dependencies in
|
|
|
|
|
the <varname>buildInputs</varname> attribute:
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
stdenv.mkDerivation {
|
|
|
|
|
name = "libfoo-1.2.3";
|
|
|
|
|
...
|
|
|
|
|
buildInputs = [libbar perl ncurses];
|
|
|
|
|
}</programlisting>
|
|
|
|
|
|
|
|
|
|
This attribute ensures that the <filename>bin</filename>
|
|
|
|
|
subdirectories of these packages appear in the <envar>PATH</envar>
|
|
|
|
|
environment variable during the build, that their
|
|
|
|
|
<filename>include</filename> subdirectories are searched by the C
|
|
|
|
|
compiler, and so on. (See <xref linkend="ssec-setup-hooks"/> for
|
|
|
|
|
details.)</para>
|
|
|
|
|
|
|
|
|
|
<para>Often it is necessary to override or modify some aspect of the
|
|
|
|
|
build. To make this easier, the standard environment breaks the
|
|
|
|
|
package build into a number of <emphasis>phases</emphasis>, all of
|
2014-06-13 10:11:27 +00:00
|
|
|
|
which can be overridden or modified individually: unpacking the
|
2008-06-19 16:00:37 +00:00
|
|
|
|
sources, applying patches, configuring, building, and installing.
|
2015-06-02 09:21:22 +00:00
|
|
|
|
(There are some others; see <xref linkend="sec-stdenv-phases"/>.)
|
2008-06-19 16:00:37 +00:00
|
|
|
|
For instance, a package that doesn’t supply a makefile but instead has
|
|
|
|
|
to be compiled “manually” could be handled like this:
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
stdenv.mkDerivation {
|
|
|
|
|
name = "fnord-4.5";
|
|
|
|
|
...
|
|
|
|
|
buildPhase = ''
|
|
|
|
|
gcc foo.c -o foo
|
|
|
|
|
'';
|
|
|
|
|
installPhase = ''
|
2012-01-18 20:16:00 +00:00
|
|
|
|
mkdir -p $out/bin
|
2008-06-19 16:00:37 +00:00
|
|
|
|
cp foo $out/bin
|
|
|
|
|
'';
|
|
|
|
|
}</programlisting>
|
|
|
|
|
|
|
|
|
|
(Note the use of <literal>''</literal>-style string literals, which
|
|
|
|
|
are very convenient for large multi-line script fragments because they
|
|
|
|
|
don’t need escaping of <literal>"</literal> and <literal>\</literal>,
|
|
|
|
|
and because indentation is intelligently removed.)</para>
|
|
|
|
|
|
|
|
|
|
<para>There are many other attributes to customise the build. These
|
|
|
|
|
are listed in <xref linkend="ssec-stdenv-attributes"/>.</para>
|
|
|
|
|
|
|
|
|
|
<para>While the standard environment provides a generic builder, you
|
|
|
|
|
can still supply your own build script:
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
stdenv.mkDerivation {
|
|
|
|
|
name = "libfoo-1.2.3";
|
|
|
|
|
...
|
|
|
|
|
builder = ./builder.sh;
|
|
|
|
|
}</programlisting>
|
|
|
|
|
|
|
|
|
|
where the builder can do anything it wants, but typically starts with
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
source $stdenv/setup
|
|
|
|
|
</programlisting>
|
|
|
|
|
|
|
|
|
|
to let <literal>stdenv</literal> set up the environment (e.g., process
|
|
|
|
|
the <varname>buildInputs</varname>). If you want, you can still use
|
|
|
|
|
<literal>stdenv</literal>’s generic builder:
|
|
|
|
|
|
|
|
|
|
<programlisting>
|
|
|
|
|
source $stdenv/setup
|
|
|
|
|
|
|
|
|
|
buildPhase() {
|
|
|
|
|
echo "... this is my custom build phase ..."
|
|
|
|
|
gcc foo.c -o foo
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
installPhase() {

2012-01-18 20:16:00 +00:00

mkdir -p $out/bin

2008-06-19 16:00:37 +00:00

specific parts of the build (e.g., unpacking the sources or installing

2008-09-02 14:54:53 +00:00
|
|
|
|
the environment variable
|
2008-06-19 16:00:37 +00:00
|
|
|
|
<varname><replaceable>name</replaceable>Phase</varname> to a string
|
|
|
|
|
containing some shell commands to be executed, or by redefining the
|
|
|
|
|
shell function
|
|
|
|
|
<varname><replaceable>name</replaceable>Phase</varname>. The former
|
|
|

is convenient to override a phase from the derivation, while the

latter is convenient from a build script.</para>

<para>GCC doesn't search in locations such as
|
|
|
|
|
<filename>/usr/include</filename>. In fact, attempts to add such
|
|
|
|
|
directories through the <option>-I</option> flag are filtered out.
|
|
|
|
|
Likewise, the linker (from GNU binutils) doesn't search in standard
|
|
|
|
|
locations such as <filename>/usr/lib</filename>. Programs built on
|
|
|
|
|
Linux are linked against a GNU C Library that likewise doesn't search
|
|
|
|
|
in the default system locations.</para>
