I tried to use mysql-connector-c++ with G-WAN 4.3.14 , here's my original source code:
//#define USE_GWAN
#include<cstdio>
#include<iostream>
#include <cppconn/driver.h>
#include <cppconn/exception.h>
using namespace std;
#ifdef USE_GWAN
#include "gwan.h"
#pragma link mysqlcppconn
#define print(x) xbuf_cat(get_reply(argv),x)
#else
#define print(x) printf(x)
#endif
int main(int argc,char** argv) {
try {
sql::Driver *driver = get_driver_instance();
sql::Connection *con = driver->connect("tcp://127.0.0.1:3306", "secret", "secret");
print("ok\n");
delete con;
} catch (sql::SQLException &e) {
print("err\n");
}
return 200;
}
It's works fine when I tried to compile it normally:
g++ -lmysqlcppconn test.cpp
But when I uncomment the //#define USE_GWAN and tried it on G-WAN, it shows:

is there anything that I should add to use mysql-connector-c++ with G-WAN?
