Trying to produce c++ versions of dmalloc libraries.The dmalloc recipe looks to be configured to build the c++ versions with:

'EXTRA_OECONF += "--enable-threads --enable-cxx --enable-shlib"'

But in the log.do_configure I see that the autoconf fails to find a c++ compiler, and I end up with the 'c' versions of the dmalloc library.

Any suggestions on how to get this recipe to build the requested c++ versions. Is there a dependency I can add in an append file to force it to recognize the compiler?
there should be a config.log generated in this component's build
directory which should have more information on what check failed and
perhaps some more errors to tell what went wrong.
