<h1>Supported platforms, compilers and languages</h1>
<p>
This page collects information on platforms (operating systems), compilers and
source code languages that are supported by the latest released ccache
version, currently <b>4.13.2</b>. The information below aims to be
correct, but new versions of e.g. an OS or a compiler may introduce new
behavior that breaks some of ccache's assumptions.
</p>
<p>
If you want to contribute new or updated information, please
<a href="https://github.com/ccache/ccache.github.io/issues/new">open an
issue</a> or maybe even create a pull request for
the <a href="https://github.com/ccache/ccache.github.io">web site
repository</a>.
