Re: [Bayonne-devel]Compiling Bayonne 1.0.8 gives "XML support is not available".

[Federico Montesino Pouzols]

        From c++ 1.0.6, xml.h will give this error when you do
"#include <cc++/xml.h>" but COMMON_XML_PARSING is not defined in
cc++/config.h (xml was not compiled when building cc++). This is
because we thought that an error should be reported in order to
prevent people from including xml.h when xml related classes are not
really there.

        Unfortunately, this change may break some applications based
on cc++ when xml support is not compiled, and I am afraid that bayonne
may be one of those. From a quick look, I see that no xml related
stuff is compiled in bayonne when COMMON_XML_PARSING is not defined
(everything is inside a "#ifdef COMMON_XML_PARSING" or a "#ifdef
XML_SCRIPTS"). However, in bayonne.h, the following lines:

#ifndef __CCXX_XML_H__
#include <cc++/xml.h>
#endif

        include xml.h without checking for COMMON_XML_PARSING, which
triggers the #error.
