ODBC X64 impossible de linker

bonjour,

j'essaie de construire une dll utilisant les librairies odbc. le tout etant sous win7 et en 64 bit

j'ai visual studio 9.0 et la seul librairie que j'ai trouver c'est
C:\Program Files\Microsoft SDKs\Windows\v6.0A\lib\odbc32.lib

or il y a un 32 dans le nom, ce qui me semble bizrre :)

j'ai quand meme essayer de linker et j'obtiens les erreurs suivantes
