Thanks all for the prompt response.

There was a problem of config parameter GCCXML_EXECUTABLE

Earlier it was set wrong to "/usr/local/bin/gccxml"

Now I have set it to "/usr/local/bin/gccxml_cc1plus"

Now it is running properly.

The argument list that gccxml generates for its internal parser
is no where close to the limit of 64-bit Linux argv[].

We don't support ccache.  Try

  gccxml --gccxml-compiler g++ example1.cxx -fxml=example1.xml
