[Cppcms-users] cppDB - ERROR: cppdb::driver failed to load driver mysql - no module found

[Daniel R. <dan...@li...>]

Hello there!, 
Im trying to run a simple example of cppDB with mysql. First cppDB installation was a PITA because the"mysql_client library was not found, disabling mysql backend, " cmake message.Since I'm a newbie in the GNU development, I've had to use saint google to found the solution..and that was install mysql development libraries. 
Anyway here's the source code I tried to run without success 
#include <cppdb/frontend.h>#include <iostream>#include <ctime>
int main(){        try {                cppdb::session sql("mysql:user=root;password=danielito;opt_reconnect=1;opt_read_timeout=10;opt_compress=1");                                         time_t now_time = std::time(0);                                std::tm now = *std::localtime(&now_time);                               cppdb::result res = sql << "SELECT id_enviroment, env_type, name FROM db_enviroment";                                while(res.next()) {                        double f=-1;                        int id,k;                        std::tm atime;                        std::string name;                        //res >> id >> k >> f >> atime >> name;                                                res >> id >> k >> name;                                                std::cout <<id << ' '<<k <<' '<<name << std::endl;                }
        }        catch(std::exception const &e) {                std::cerr << "ERROR: " << e.what() << std::endl;                return 1;        }        return 0;}
Compilation with: g++ dbtest.cpp -lcppdb -o dbtest 
Run with./dbtestERROR: cppdb::driver failed to load driver mysql - no module found 
Im doing it right ? 
Thanks !

Try to check if your libcppdb.so is in /usr/lib folder or not?
I assume you are using Linux.
