gSoap compilation with c++ - c++

Question

I'm trying to get a simple example working using gSoap, for VS2008.
I've done the following:
wsdl2h -o Init.h http://myservices/InitalisationService.asmx?WSDL
And then this:
soapcpp2 -I "C:\3pSDK\gsoap-2.7\gsoap\import" -i -C -limport Init.h
which produces many files. My project folder looks like this:
// generated files
Init.h
InitalisationServiceSoap.initalizePlayer.req.xml
InitalisationServiceSoap.initalizePlayer.res.xml
InitalisationServiceSoap.nsmap
InitalisationServiceSoap12.initalizePlayer.req.xml
InitalisationServiceSoap12.initalizePlayer.res.xml
InitalisationServiceSoap12.nsmap
ortC.cpp
ortH.h
ortInitalisationServiceSoap12Proxy.cpp
ortInitalisationServiceSoap12Proxy.h
ortInitalisationServiceSoapProxy.cpp
ortInitalisationServiceSoapProxy.h
ortMatlab.c
ortMatlab.h
ortStub.h
// Project Files
ReadMe.txt
stdafx.cpp
stdafx.h
WebServicesClient.cpp
WebServicesClient.vcproj
targetver.h
// files added to the project from gSoap folder
stdsoap2.cpp
stdsoap2.h
typemap.dat
When I build, I get a lot of linker errors (unresolved externals). I can't find anything to link against (e.g. no binary libraries) - what am I missing?
I believe that this may have something to do with the following from the docs:
To complete the build, compile and
link the generated soapC.cpp,
soapcalcProxy.cpp, and the run-time
gSOAP engine -lgsoap++ (or use source
stdsoap2.cpp in case libgsoap++.a is
not installed) with your code.
is there a gsoap++ library for win32?

Okay, for those frustrated with the docs on the gSoap site, using VS2008 to compile a quick client only example, here's the steps (servers are different).
Generate the header file from the WSDL:
wsdl2h -o Init.h http://bleh.com/myservice.asmx?WSDL
Generate the soap client files:
soapcpp2 -C -IC:\3pSDK\gsoap-2.7\gsoap\import Init.h
Ensure you add the following files to your solution for build:
soapC.cpp, soapClient.cpp, and stdsoap2.cpp
Ensure that, for each of these files, you select the compiler option "Not using Pre-Compiled headers". (file Properties -> C++ -> Precompiled Headers -> Create/Use Precompiled header).
Finally, add the .nsmap file generated for your proxy to the stdafx.h (or in your main if your project isn't using pre-compiled headers).
Here's a sample that makes a simple query:
// WebServicesClient.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "init/soapInitServiceSoapProxy.h"
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
std::string user = "AAAA";
std::string pass = "BBBB";
InitServiceSoap service;
_ns1__initPlayer query;
_ns1__initPlayerResponse ans;
query.psParam1 = &user;
query.psParam2 = &pass;
if( service.__ns2__initPlayer(&query, &ans) == SOAP_OK )
{
cout << "success!" << endl;
}
cin.get();
return 0;
}
hope this helps someone!
