[c++] conflitto tra librerie

[Infernal]

Sto scrivendo un programma in cui uso la libreria Freeimage, il problema è che nel programma devo includere anche windows.h, e quando compilo mi vanno in confilitto (credo) gli header di freeimage con quelli di windows.h

come posso fare?

ps: la libreria windows.h la uso solo per la Sleep()... se c'è un altro modo per fare attendere il programma tolgo windows.h e uso quello....

grazie a tutti!

gli errori sono questi:

[pallinopinco]

Cerca nel forum, la soluzione è stata proposta qualche giorno fa.

[Infernal]

scusa se rompo... ma non trovo niente con la ricerca del forum... ti ricordi come si chimava il topic più o meno? thanks

[pallinopinco]

Cosa hai cercato?

Dovresti trovarlo facilmente visto che si tratta di una discussione alla quale TU hai partecipato.

[Infernal]

cose tipo:

conflitto librerie
freeimage e windows.h
freeimage
windows.h

io non mi ricordo di aver partecipato... cioè.. mi ricordo di quando mi hai detto di aggiungere il #define _WINDOWS_ ma l'ho aggiunto e lo fa lo stesso...

[pallinopinco]

L'hai aggiunto nel modo o nel punto sbagliato, io l'ho fatto e funziona perfettamente.

Questo è l'output del compilatore PRIMA della modifica:

Come puoi vedere è stato creato l'eseguibile dell'esempio LoadFromMemory.cpp al quale ho aggiunto un #include <windows.h>.

io non mi ricordo di aver partecipato

Ci sono 2 Infernal in questo forum o hai una doppia personalità?

[Infernal]

risolto.. dovevo prima includere windows.h e poi freeimage.h...... ma perchè? hce differenza c'è nell'includere prima uno e poi l'altro?

A volte capita che mi trasformo e non mi ricordo cosa ho fatto nell'altra vita.... ma dopo un po' passa...


grazie mille... (come sempre)

... nell'includere prima uno e poi l'altro?

Beh ... la compilazione e' un processo sequenziale ...

Se un tipo di dato o una costante viene definita dal primo include e usato nel secondo, al contrario, non pensi che ci possano essere problemi?

[Infernal]

sisi... su questo sono d'accordo.. ma visto che freeimage non ha bisogno di windows.h non penso utilizzi tipi o funzioni definiti in windows.h...
