IVF 11.1.067 with f90SQL Library

[Peter_Skerlj]

Hi,

I have been using CanaimaSoft's f90SQL library with IVF for a couple of years now to be able to read/write SQL data from my fortran code. I have just recently switched jobs and I am trying to get some old fortran code running on my new computer.

I get an error when trying to establish an ODBCconnection with the following subroutine call:

call f90SQLConnect(ConnHndl, 'ODBC_Name', 'Username', 'Password', RetCode)

The error when running theconsole applicationis:
forrtl: severe (170): Program Exception - stack overflow

And when I debug the program inMS Visual Studio, theerror is:
Debug Assertion Failed!
File: winsig.c Line 419
Expression: ("Invalid signal or error", 0)

I am using:
Win32 console application in IVF 11.1.067
Visual Studio 2008 Version 9.0.21022.8
MS .Net Framework Version 3.5 SP1
Windows 7 Professional 32-bit OS

The code worked fine in my previous job.

Does anyone have an idea what the problem is and how to fix it?

Thanks.

My first guess would be that this is due to different calling conventions.
The Canaima library is a rather old one and most probably uses the STDCALL convention.
IVF uses the C convention (if I remember the name correctly) by default.
Look in the compiler options - there is an option to change the calling convention.

Hi Arjen,

Thanks for your suggestion. However, changing to theSTDCALL convention (/Gz) did not solve the problem. I actually gave me 11 unresolved externals symbol errors.

Thanks.

Hm, I know too little about the library to come up with further suggestions ...
(There was another thread a couple of weeks ago which related to SQL as well - maybe that will
bring you some ideas? You might try my interface to oDBC if all else fails - http://flibs.sf.net)
