Dear fellow monks,

Recently I have aquired version 12.0 of Sybase OpenClient, and my old DBD does not work any more. Well to be more specific, the perl script prints the error message "Invalid context version" at the "use DBD::Sybase" clause, and proceed with the rest of the code without problem.

I have done some research on the net, and found out that the warning message gets printed when the version of the DBD::Sybase driver was compiled with earlier version of Sybase OCS.

So I have downloaded the latest version of DBD-Sybase from CPAN, and tried to build the new Sybase.dll. By the way, I am using Borland C++ 5.5 on my XP system.

I ran perl Makefile.PL and created a Makefile. However, most of the directives in the Makefile were really geared towards Microsoft Visual C that I do not have. I have modified the Makefile to compile with the Borland compiler. The compilation had many errors, which I fixed one by one, and finally it created an empty DLL of only 2K in size. This cann't be right. But the compiler reported success on the build?!

By the way, the linker has complained about missing __turboFloat from root, which I have patched by adding unsigned long _turboFloat; to the dbimp.c file. And also it complained about the format of Perl58.lib and libct.lib etc., which I fixed by running the Borland implib utility on the DLL's.

My question is, has anyone here ever compiled DBD::Sybase with Borland C++ compiler before? If so, could you please offer some expert advise on how to setup the Makefile and environment to compile the DLL properly? Am I missing some command-line switches?

Your comment and help are greatly appreciated!
