ccache: rework ccache management
* ccache is now a normal package (both for the host and the target). * ccache option is now part of the "Build options" menu. It will automatically build ccache for the host before building anything, and will use it to cache builds for both host compilations and target compilations. * bump ccache to 3.1.3 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2011.02, Not yet released:
|
||||
|
||||
Ccache support reworked. Now used for both host and target
|
||||
compilation, and cache is stored in ~/.buildroot-ccache.
|
||||
|

Updated/fixed packages: cloop, m4, openssh, xz

New packages: lsuio

<h2 id="ccache-support">Using <code>ccache</code> in Buildroot</h2>
|

|

<p><a href="http://ccache.samba.org">ccache</a> is a compiler
|
||||
cache. It stores the object files resulting from each compilation
|
||||
process, and is able to skip future compilation of the same source
|
||||
file (with same compiler and same arguments) by using the
|
||||
pre-existing object files. When doing almost identical builds from
|
||||
scratch a number of times, it can nicely speed up the build
|
||||
process.</p>
|
||||
|
||||
<p><code>ccache</code> support is integrated in Buildroot. You
|
||||
just have to enable <code>Enable compiler cache</code>
|
||||
in <code>Build options</code>. This will automatically build
|
||||
<code>ccache</code> and use it for every host and target
|
||||
compilation.</p>
|
||||
|
||||
<p>The cache is located
|
||||
in <code>$HOME/.buildroot-ccache</code>. It is stored outside of
|
||||
Buildroot output directory so that it can be shared by separate
|
||||
Buildroot builds. If you want to get rid of the cache, simply
|
||||
remove this directory.</p>
|
||||
|
||||
<p>You can get statistics on the cache (its size, number of hits,
|
||||
misses, etc.) by running <code>make ccache-stats</code>.</p>
