Hi,
It took me some seven days to compile and successfully link DBI::Sybase1.08 against Sybase OCS15 on Mingw / Windows Vista. I would surely share my trick, it is really difficult to link sybase libraries using Mingw. If I link on VC8, it is linked to msvcr80.dll. It fails to load because of windows side by side dll installation. So I tried to link using free Mingw, it links with msvcrt.dll. Downloaded mingw, binutils, unix utils (unixutils.sourceforge.net) and nmake from VC8\bin. I followed the articles at: http://mingw.org/mingwfaq.shtml#faq-msvcdll http://sapdb.2scale.net/maxdb-wiki/MS_C++_Toolkit http://www.geocities.com/yongweiwu/stdcall.htm And created my own libraries out of %sybase%\dll\* Step1: Create the following sed file, call it exp.sed / \t*ordinal hint/,/^ \t*Summary/{ /^ \t\+0-9\+/{ s/^ \t\+0-9\+ \t\+0-9A-Fa-f\+ \t\+0-9A-Fa-f\+ \t\+\(.*\)/\1/p } } Step2: Create following batch file, call it genlib.bat echo LIBRARY %1.dll > %1.def echo EXPORTS >> %1.def link -dump -exports %1.dll | sed -nf c:\temp\DBD-Sybase-1.08\exports.sed >> %1.def dlltool -U -d %1.def -l %1.a Step3: go to %sybase%\dll and run the following loop (type it on dos prompt and press enter) for /f %i in ('dir /b *.dll') do a %~ni & move /Y %~ni.a ..\lib\ & del %~ni.def Step4: Go to DBD-Sybase-1.08 directory, edit makefile.pl, change libct to libsybct.a etc .. and run nmake it compiles and links correctly, but all the tests fail!!! -------------------------------------------------------- ERROR: # Tried to use 'DBD::Sybase'. # Error: Can't load 'C:\temp\DBD-Sybase-1.08\blib\arch/auto/DBD/Sybase/Sybase.dll' for module DBD::Sybase: load_file:The specified procedure could not be found at C:/Perl/lib/DynaLoader.pm line 201. -------------------------------------------------------- So I tried again to debug: Went to "DBD-Sybase-1.08\blib\arch\auto\DBD\Sybase" and issued "link -dump -exports Sybase.dll" The following dump clearly shows there aren't any methods exported. It seems the __declspec(export) is not evaluated by some preprocessor macro during compilation.
Michael could you please help me, here? Thanks, Sanjit
