<glossdef>
<para>
Specifies additional paths from which the OpenEmbedded
build system gets source code.
When the build system searches for source code, it first
tries the local download directory.
If that location fails, the build system tries locations
defined by <filename>PREMIRRORS</filename>, the upstream
source, and then locations specified by
<link linkend='var-MIRRORS'><filename>MIRRORS</filename></link>
in that order.
</para>
<para>
Assuming your distribution
(<link linkend='var-DISTRO'><filename>DISTRO</filename></link>)
is "poky", the default value for
<filename>PREMIRRORS</filename> is defined in the
<filename>conf/distro/poky.conf</filename> file in the
<filename>meta-yocto</filename> Git repository.
</para>
<para>
Typically, you could add a specific server for the
build system to attempt before any others by adding
something like the following to the
<filename>local.conf</filename> configuration file in the
<ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>:
<literallayout class='monospaced'>
PREMIRRORS_prepend = "\
git://.*/.* http://www.yoctoproject.org/sources/ \n \
ftp://.*/.* http://www.yoctoproject.org/sources/ \n \
http://.*/.* http://www.yoctoproject.org/sources/ \n \
https://.*/.* http://www.yoctoproject.org/sources/ \n"
</literallayout>
These changes cause the build system to intercept
Git, FTP, HTTP, and HTTPS requests and direct them to
the <filename>http://</filename> sources mirror.
You can use <filename>file://</filename> URLs to point
to local directories or network shares as well.
