Hello Markus,

compiles OK here, don't forget to have
-lodbc32
in the Project\Project Options\Parameters tab\Linker textbox

Have a nice day,
Michal

Hi,

I'm using Dev C++ 5.7.1. on a windows 7 Prof SP1 x64 and have linking errors when I'm trying to use even the simplest ODBC function. (Example bottom end)

C:\Program Files (x86)\Dev-Cpp\MinGW64\x86_64-w64-mingw32\lib\libodbc32.a is existing and ODBC is working with the Pelles C implementation on my system too.

For example with
"
#define WIN32_LEAN_AND_MEAN
#define WIN32_DEFAULT_LIBS
#include <windows.h>
#include <sql.h>
#include <sqlext.h>

int main(int argc, char** argv) {

            static SQLHENV global_env_handle;
            SQLAllocHandle(SQL_HANDLE_ENV,SQL_NULL_HANDLE,&global_env_handle);

            return 0;
}
"
I've got the error 10                  N:\demo\main.cpp        undefined reference to `SQLAllocHandle'.

May this is related to http://bytes.com/topic/c/answers/160335-sqlext-h-odbc-link-time-error-dev-c-ide-mingw-compiler ?! Too bad all links there are dead.
