[Gdal-dev] Building DLL's on Windows

[Ari Jolma]

Sorry, this is not in fact GDAL issue, but I know here are some 
knowledgeable people.

I've tried with a colleague to compile libral on Windows. I've used 
Cygwin and gcc and descriptions on cygwin site. I manage to make a DLL, 
and I can study it using, e.g., dependency walker. But when I try to use 
it I have problems. I tried the simplest possible DLL and then Windows 
Perl & module Win32::API, with which I should be able to open and call 
any DLLs. I can call a function from Kernel32.dll but not from my DLL.

I selected cygwin, because configure works there. configure worked but 
did not produce a DLL (it produces a shared object in linux ok).

Does anybody have good pointers or advice what to try next? The idea is 
to produce a libral DLL, which would then be called from MapWindow in 
this case. GDAL would or is probably also used by MapWindow.

Thanks,

Ari
