SOAP 1.2 fault SOAP-ENV:Sender[no subcode] - c++

Question

Accessing IIS webservice using Gsoap.
I have similar error as in this link shows that the error was solved compiling with -lssl.
I did the same thing in build as
g++ -o client client.cpp stdsoap2.cpp soapC.cpp soapDataManagementSoapProxy.cpp -I /usr/local/ssl/include -L/home/xavier/GSOAP/lib -lgsoapssl++ -L/usr/local/ssl/lib -lssl
My GSOAP lib was build with OpenSSL.
But I still have error as
SOAP 1.2 fault SOAP-ENV:Sender[no subcode]
"OpenSSL not installed: recompile with -DWITH_OPENSSL"
Detail: [no detail]
My test code is as follow. What could be wrong?
#include "soapDataManagementSoapProxy.h"
#include "DataManagementSoap.nsmap"
const char server[] = "https://XXXXXXX.com/XXXmanagement.asmx";
int main(int argc, char **argv)
{
DataManagementSoapProxy webinf;
webinf.soap_endpoint = server;
_tempuri__ReadTestData* a;
_tempuri__ReadTestDataResponse res;
int ret = webinf.ReadTestData(a, res);
if (webinf.error){
webinf.soap_stream_fault(std::cerr);
}
else{
//printf("result = %g\n", result);
std::cout << "Success " << std::endl;
}
webinf.destroy(); /* clean up mem */
return 0;
}

Solution for this issue is
#include "calc.nsmap"
#include "soapcalcProxy.h" // generated with soapcpp2 -j calc.h
calcProxy calc("https-server-endpoint-URL");
double sum;
soap_ssl_init(); // init SSL (just need to do this once in an application)
// soap_ssl_no_init(); // or prevent init OpenSSL when already initialized elsewhere in an application
if (soap_ssl_client_context(calc.soap,
SOAP_SSL_DEFAULT,
NULL, // no keyfile
NULL, // no keyfile password
"cacerts.pem", // trusted certificates (or use self-signed cacert.pem)
NULL, // no capath to trusted certificates
NULL // no random data to seed randomness
))
{
calc.soap_stream_fault(std::cerr);
exit(EXIT_FAILURE);
}
if (calc.add(1.23, 4.56, sum) == SOAP_OK)
