XML/C++ type binding goes wrong - c++

Question

I have a WSDL file which I need to generate a c++ web service code from it. The toolchain I'm using is gSOAP.
The problem is that the generated server class, have a function for each operation with parameters as char* instead of something like ns2__something structs. How can I force gSOAP to generate XML/C or XML/C++ binding (according to my understanding of gSOAP documentation it should do so [?])
WSDL file:
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="swus"
targetNamespace="swus.wsdl"

soapcpp2 -2 -S -a -A -t -c++11 -b -i ./SWUS.h
Generated code snippet:
class SOAP_CMAC swusService : public soap {
public:
/* blah blah blah... */
/// Web service operation 'add' (returns SOAP_OK or error code)
virtual int add(char *wsdl__addRequestElement, // =====>> Why?
char *wsdl__addResponseElement // =====>> Why?
) SOAP_PURE_VIRTUAL;
};

Answer 1

The WSDL file is mixing two namespaces (tns and swus).
Add swus: to the request and response element types:
<message name="addRequest">
<part name="parameters" element="swus:addRequestElement"/>
</message>
<message name="addResponse">
<part name="result" element="swus:addResponseElement"/>
</message>
gSOAP should match now the correct types:
virtual int add(
_ns2__addRequestElement *ns2__addRequestElement,
_ns2__addResponseElement &ns2__addResponseElement
) SOAP_PURE_VIRTUAL;
