<title>Default <c>src_install</c></title>
<body>
<p>
For EAPIs 4 and later, the default <c>src_install</c> function is the following:
</p>
<codesample lang="ebuild">
src_install() {
if [[ -f Makefile ]] || [[ -f GNUmakefile ]] || [[ -f makefile ]] ; then
emake DESTDIR="${D}" install
fi
if ! declare -p DOCS >/dev/null 2>&1 ; then
local d
for d in README* ChangeLog AUTHORS NEWS TODO CHANGES THANKS BUGS \
FAQ CREDITS CHANGELOG ; do
[[ -s "${d}" ]] && dodoc "${d}"
done
elif [[ $(declare -p DOCS) == "declare -a"* ]] ; then
dodoc "${DOCS[@]}"
else
dodoc ${DOCS}
fi
}
</codesample>
<p>
For EAPIs 6 and later, the default <c>src_install</c> function is the following:
</p>
<codesample lang="ebuild">
src_install() {
if [[ -f Makefile ]] || [[ -f GNUmakefile ]] || [[ -f makefile ]] ; then
emake DESTDIR="${D}" install
fi
einstalldocs
}

<title>Sample <c>src_install</c></title>

<section>
<title>Easy installs</title>
<body>
<p>
Often, especially with autotools-powered packages, there is a <c>Makefile</c>
<c>install</c> target which will honour the <c>DESTDIR</c> variable to tell it to
install to a non-root location. If possible, this should be used:
</p>
<codesample lang="ebuild">
emake DESTDIR="${D}" install
</codesample>
<note>
<c>emake</c> should be used to parallelise here. Some installs are
not designed to be parallelised, use <c>emake -j1</c> or <c>make</c>
if you hit an error.
</note>
<p>
Usually the package's build system will not install the <c>README</c>,
<c>ChangeLog</c>, etc. files, so it is necessary to include additional
<c>dodoc</c> statements for them:
</p>
<codesample lang="ebuild">
emake DESTDIR="${D}" install
dodoc README CHANGES
dodoc -r doc
</codesample>
<p>
<c>dodoc</c> supports <c>-r</c> as the first argument, which allows directories
to be installed recursively.
</p>
<note>
There is no need for <c>dodoc COPYING</c>! The license belongs in the
repository's <c>licenses/</c> directory. Sometimes though, you might want to
install <c>COPYING</c> regardless, if it explains how different licenses are
applied to different parts of the application, for example.
</note>
</body>
</section>
<section>
<title>Trivial installs</title>
<body>
<p>
For some packages with no <c>Makefile</c> that only install a small
number of files, writing a manual install using <c>cp</c> is the
easiest option. For example, to do a simple install of some (no
compilation required) themes:
</p>
<codesample lang="ebuild">
dodir /usr/share/foo-styles/
cp -R "${S}/" "${D}/" || die "Install failed!"
</codesample>
<p>
Or sometimes a combination of <c>insinto</c> and <c>doins</c> (plus related
functions <d/> see <uri link="::function-reference/install-functions/"/>) <d/>
the following is based upon the <c>sys-fs/udev</c> install:
</p>
<codesample lang="ebuild">
src_install() {
dobin udevinfo
dobin udevtest

<p>
This is, of course, considerably harder to handle than a
simple <c>Makefile</c> driven install.
</p>
</body>
</section>
<section>
<title>Other installs</title>
<body>
<p>
Sometimes, there will be a <c>Makefile</c> that does not
honour <c>DESTDIR</c> and a non-trivial number of files to install. In
these situations, it is best to patch the <c>Makefile</c> and contact
upstream explaining the situation to them.
