hi everyone,
I have problem with connecting to timesten database can u help.
following is the code:
#ifdef WIN32
# include <windows.h>
#else
# include <sqlunix.h>
#endif
#include <sql.h>
#include <sqlext.h>
#include <stdio.h>

int main(int ac, char** av)
clrscr();
SQLRETURN rc = SQL_SUCCESS;
/* General return code for the API */

rc = SQLAllocEnv(&henv);
if (rc != SQL_SUCCESS) {
fprintf(stderr, "Unable to allocate an "
"environment handle\n");
exit(1);
rc = SQLAllocConnect(henv, &hdbc);
chkReturnCode(rc, henv, SQL_NULL_HDBC,
SQL_NULL_HSTMT,

          while (ret == SQL_SUCCESS ||ret == SQL_SUCCESS_WITH_INFO)
               ret = SQLError(henv, hdbc, hstmt,

          } /* while */
          if (rc != SQL_SUCCESS_WITH_INFO && err_is_fatal)
               fprintf(stderr, "Exiting.\n");
               exit(-1);
m getting error in the functions:
SQLAllocEnv(...)
SQLAllocConnect(...)
SQLDriverConnect(..)
SQLAllocStmt(...)
as undefined symbol.
one more thing while compiling it shows no error but when running it shows linking error::Undefined Symbol
wtg for some response
Thanks

Hi Pooja,
If you look at the C examples/demos that get installed with TimesTen you will find example Makefiles that have all this information plus lots of other useful stuff. I would recommend that you base your Makefiles or build scripts on what you see in there since the compilation and linker directives etc. are of course platform dependent and the demo Makefiles are the right ones for your specific platform.
