[fpc-pascal] Compiling library / Win32 DLL

[chromdildo]

Hallo list.

I'm having trouble with library/DLL under Win32 (exporting one function
and having a little GUI).
Compiles fine, but the host application can't load them. The Host is
closed source (think MSVC).

Same code compiles and runs fine with Delphi.

Can someone describe the main differences with building/linking
libraries under Delphi/freepascal.
I'm sure I'm missing some compiler/linker - switch.

Thank you very much

P.S. Merry Xmas and happy new year to all.
