#chdir_for_build ⇒ Object

When using rake-compiler-dock on Windows, the underlying Virtualbox shared folders don’t support symlinks, but libiconv expects it for a build on Linux. We work around this limitation by using the temp dir for cooking.

Team Nokogiri will keep on doing their best to provide security

to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

        [--with-xslt-config=/path/to/xslt-config]
