I use lazarus_3_0_RC1-10-gfe49fef4fc x86_64-win64-win32/win64 to develop performance measuring tool for various exchange boards. Connecting to bybit I discover that to get trade signature they use other SHA256 hasher than one in their OpenSSL. I am lazy enough to search for appropriate SHA version, so I try to use ther hash.pyd library wrapped with tiny Python module (their API docs have no C or Pascal recomendations).
So I took Pyton4delphi and installed p4dlaz.lpk. Opening Demo01\project1.lpr I get 'no TpihonGUIInputOutput class' and a demand to install p4dlaz when pressing F12. I've looked through p4dlaz and found no traps of design-time items. And no Python tab appears at my palette. Is something fogotten in FPC installation guide? For Delphi we need separate packages for run-time and design-time parts. May be we have missed some package revolution in Lazarus?
PS Don't you know a simple way to extract real DLL from .pyd?
