Failed to compile gsoap-generated server code with C++ Builder - c++

Question

I am trying to build a server application using gsoap 2.8.17. I've created a header file with service function prototype and a result record definition
testserver.h:
#ifndef TESTSERVER_H
#define TESTSERVER_H
#include <string>
//gsoap ns service name: TestServer
//gsoap ns service namespace: http://mycomp:8080/TestServer.wsdl
//gsoap ns service location: http://mycomp:8080/TestServer.cgi
//gsoap ns schema namespace: urn:TestServer
class Record
{
public:
int id;
std::string name;
std::string address;
double param1;
};
int ns__GetRecord(int id, Record* result);
#endif
Then I've invoked the gSOAP RPC compiler:
soapcpp2.exe testserver.h
The compiler produced the following files:
soapC.cpp
soapClient.cpp
soapClientLib.cpp
soapServer.cpp
soapServerLib.cpp
soapH.h
soapStub.h
TestServer.h
TestServer.nsmap
TestServer.wsdl
TestServer.GetRecord.req.xml
TestServer.GetRecord.res.xml
ns.xsd

As documentation recommends I added soapServerLib.cpp to my project, but the C++ Builder 2010 compiler produces errors:
[BCC32 Error] soapC.cpp(1611): E2238 Multiple declaration for 'ns__GetRecord(soap *,int,Record *)'
[BCC32 Error] soapStub.h(224): E2344 Earlier declaration of 'ns__GetRecord(soap *,int,Record *)'
[BCC32 Error] soapC.cpp(1611): E2303 Type name expected
[BCC32 Error] soapC.cpp(1611): E2379 Statement missing ;
[BCC32 Error] soapC.cpp(1717): E2379 Statement missing ;
soapStub.h(224):
SOAP_FMAC5 int SOAP_FMAC6 ns__GetRecord(struct soap*, int id, Record *result);
soapC.cpp(1598-1619):
SOAP_FMAC1 struct ns__GetRecord * SOAP_FMAC2 soap_instantiate_ns__GetRecord(struct soap *soap, int n, const char *type, const char *arrayType, size_t *size)
{
(void)type; (void)arrayType; /* appease -Wall -Werror */
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "soap_instantiate_ns__GetRecord(%d, %s, %s)\n", n, type?type:"", arrayType?arrayType:""));
struct soap_clist *cp = soap_link(soap, NULL, SOAP_TYPE_ns__GetRecord, n, soap_fdelete);
if (!cp)
return NULL;
if (n < 0)
{ cp->ptr = (void*)SOAP_NEW(struct ns__GetRecord);
if (size)
*size = sizeof(struct ns__GetRecord);
}
else
{ cp->ptr = (void*)SOAP_NEW_ARRAY(struct ns__GetRecord, n); // <<<-- error here
if (size)
*size = n * sizeof(struct ns__GetRecord);
}
DBGLOG(TEST, SOAP_MESSAGE(fdebug, "Instantiated location=%p\n", cp->ptr));
if (!cp->ptr)
soap->error = SOAP_EOM;
return (struct ns__GetRecord*)cp->ptr;
}
Why is ns__GetRecord interpreted as a structure while it's a function name? What should I fix in my TestServer.h to make soapcpp2.exe produce a compilable code ?

Answer 1

The only solution I found is to remove the soap_instantiate_ns__GetRecord function body.
SOAP_FMAC1 struct ns__GetRecord * SOAP_FMAC2 soap_instantiate_ns__GetRecord(struct
soap *soap, int n, const char *type, const char *arrayType, size_t *size)
{
return NULL;
}
Then the server code compiles and works fine.
