http://nagoya.apache.org/bugzilla/show_bug.cgi?id=27220 Forward declaration of classes-namespace problem Summary: Forward declaration of classes-namespace problem Product: Xerces-C++ Version: 2.4.0 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: DOM AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I created classes that wrap Xerces functionality. The users of my classes don't need to know Xerces, only these classes. The classes have private pointers to DOMDocument and DOMElement. I order to prevent the need to include the xerces header files, I tried to forward declare them in my header file like this: namespace xercesc { class DOMDocument; class DOMElement; }; but this didn't compile claiming that namespace aliases can't be used. Changing to this: XERCES_CPP_NAMESPACE_BEGIN class DOMDocument; class DOMElement; XERCES_CPP_NAMESPACE_END worked, but again, my users will have to know these macros (which declared only in xerces header files). Of course I can change the namespace directly to xercesc_2_5_0, but this will force me to to change it each time I upgrade. I'm using gcc 3.2.3 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
