Dann hast du evtl. noch einen anderen Fehler gemacht. Geht es jetzt oder was kommen jetzt für Fehler?

Du mußt die md5.cpp mit in das Projekt einbinden und dazulinken. \edit: oder die Bibliothek - je nachdem was du installiert hast.

Ich wieß ja nicht was du runtergeladen hast. Aber die Datei wäre hier: http://www.garret.ru/~baranov/boost_md5/lib/md5/md5.cpp
Die mußt du nur in dein Projekt mit einfügen, kompiliert und gelinkt wird sie dann automatisch.
Gruß
ich bekomm es einfach nich hinich hab umber die dev c++ updates boost geladen
dann von
