HI all-
I entered in the following code and it compiles with no errors but then I
get linker errors. Below is the code and the linker errors. Please provide
any tips so that I can link correctly. I tried to include all the paths
libraries and include directories in my environment. I put the following
link line in the IDE:
-Wl,--stack,20000000 -o cyclone.exe
-LC:/msys64/usr/local/firebird-3.0/lib64 -lsoci_empty_4_0 -lsoci_core_4_0
-lsoci_firebird_4_0
I think it is something that I am missing and I don't blame it on MinGW or
SOCI. My cmake to build worked perfectly!
#include "soci/soci.h"
#include "soci-firebird.h"
#include <iostream>
#include <istream>
#include <ostream>
#include <string>
#include <exception>
using namespace soci;
using namespace std;
int main()
{
try
{
session sql(firebird, "service=C:/Program
Files/Firebird/Firebird_3_0/examples/empbuild/EMPLOYEE.FDB user=SYSDBA
password=masterkey");
int count;
sql << "select count(*) from phonebook", into(count);
cout << "We have " << count << " entries in the phonebook.\n";
}
catch (exception const &e)
{
cerr << "Error: " << e.what() << '\n';
}
