[visual c++] Debug si, release no...perchè??

[valentino861]

Ho fatto un programmino usando delle librerie esterne GarXface, ma non riesco a compilarlo in versione release, mentre in debug va benissimo, perchè?
Mi da questi errori:

Guarda nelle opzioni del progetto e verifica che le librerie necessarie siano state linkate sia nella versione debug che quella release. Secondo me è questo il problema.

[valentino861]

esatto grazie non erano linkate in release.

Grazie
