SDL - Using correct SDL.dll

[Milsa]

I have application in Lazarus for 32 or 64 bit Windows. When I start this application it searches SDL.dll. But SDL.dll is 2 versions (32 and 64 bits) and its aren't compatible with other Windows.

How can I ensure that 32-bit Windows uses SDL32.dll and 64-bit Windows uses SDL64.dll.

Files SDL32.dll and SDL64.dll are my files after rename from SDL.dll for xx-bit paltform.

How can I ensure that 32-bit Windows uses SDL32.dll and 64-bit Windows uses SDL64.dll.

Windows uses the library that you specify. Therefore, for 64 and 32 bit versions of your program, use different names

Code: Pascal  [Select][+][-]

1. const
2.   SDL_dll = {$IFDEF WIN64}'SDL64.dll'{$ELSE}'SDL32.dll'{$ENDIF};
3.  
4. procedure SomeProcFromDll(...); external SDL_dll;
