Using pypyodbc on Mac about pypyodbc

[GoogleCodeExporter]

I was able to figure out the reason for the

"[iODBC][Driver Manager]Data source name not found and no default driver 
specified. Driver could not"

error.I added the proper odbc.ini and odbcinst.ini but the original decode 
error still persists.

This call from pypyodbc.py is failing 

try:
                lock.acquire()
                ret = odbc_func(self.dbc_h, 0, c_connectString,len(self.connectString), None, 0, None, SQL_DRIVER_NOPROMPT)

            finally:
                lock.release()


The ret value is -1 which corresponds to SQL_ERROR. And the odbc_func is 
"ODBC_API.SQLDriverConnectW"

Also I further added debugging to identify the type of specific sql state we 
were seeing.
Since we seem to be going through the non ansi part right before calling the 
above odbc_connect function looking at the rest of your file I added this


try:
                lock.acquire()
                ret = odbc_func(self.dbc_h, 0, c_connectString, len(self.connectString), None, 0, None, SQL_DRIVER_NOPROMPT)
                if ret == SQL_ERROR:
                        stateE = create_buffer_u(22)
                        MessageE = create_buffer_u(1024*4)
                        ODBC_funcE = ODBC_API.SQLGetDiagRecW
                        raw_sE = unicode
                        NativeErrorE = ctypes.c_int()
                        Buffer_lenE = c_short()
                        val = ODBC_funcE(SQL_HANDLE_DBC, self.dbc_h,1, stateE,ADDR(NativeErrorE), MessageE, 1024, ADDR(Buffer_lenE))
                        print val
                        print MessageE.value
            finally:
                lock.release()


The value of 'val' printed is 0.And MessageE.value is '['.StateE.value is 0. 
NativeErrorE.value is 20013(but I dont find any interpretation for that here?)

Does the implementation of ODBC_API.SQLGetDiagRecW here look correct?

I get the exact same issue as well.

Although this specific error above goes away when I:

brew install unixodb

But then I get a different error:
