Compilerfehler mit Header File
-
Hallo zusammen,
Ich habe ein böses Problem welches ich nicht so ganz verstehe.Folgendes header file wirft bei mir die nachstehenden fehler:
#ifndef GETPUT_H #define GETPUT_H /*------------ macros for storing/extracting msb first words -------------*/ #define GET_32BIT(cp) (((unsigned long)(unsigned char)(cp)[0] << 24) | ((unsigned

Ich hoffe jemand von euch kann mir hier helfen, ich verzweifle beinahe.

Hab ich mal gemacht, aber habe dennoch immer noch genau die selben fehler... Noch andere Ideen?
-
Der Präprozessor arbeitet zeilenweise (im Gegensatz zum Compiler), deshalb werden die Fortsetzungszeilen nicht mehr zu den jeweiligen Makros zugeordnet. Wenn du eine Makro-Definition über mehrere Zeilen verteilen willst, mußt du mit einem \ am Ende kennzeichnen, daß die aktuelle Zeile (logisch) weitergeht - und das bei allen deinen mehrzeiligen Makro-Definitionen.
(PS: Ich hoffe mal, das ist nur ein Ausschnitt des kompletten Files - die Zeilenangaben der Fehlermeldungen passen nämlich nicht ganz dort rein)
-
Wie war denn die Vorgeschichte dieser Fehlermeldungen? Sind sie einfach plötzlich vom Himmel gefallen?
-
So, hier noch einaml das angepasste file, sowie die neuen Fehlermeldungen. was hat das nun zu bedeuten?

Hinter diese letzten Zeilen vom define kommt natürlich kein \ mehr
Quasi
#define PUT_32BIT(cp, value) do { \ (cp)[0] = (value) >> 24; \ (cp)[1] = (value) >> 16; \ (cp)[2] = (value) >> 8; \ (cp)[3] = (value); } while (0)anstatt
#define PUT_32BIT(cp, value) do { \ (cp)[0] = (value) >> 24; \ (cp)[1] = (value) >> 16; \ (cp)[2] = (value) >> 8; \ (cp)[3] = (value); } while (0)\

Auch auf die Gefahr hin, mich selbst zu zitieren:

Wo in dem geposteten Ausschnitt liegt denn die Zeile 56?
-
Ja stimmt, es war eigentlich das komplette File, aber die ersten paar Zeilen habe ich weggelassen, da dort nur irgendwelche definitionen als kommentar stehen.
Na ja, es funktioniert jetzt, nachdem ich das File noch einmal komplett neu kopiert habe, sowie anschliessend die \ wie von feigling beschrieben eingefügt habe.
Vielen Dank auf jeden fall für eure schnelle Hilfe, es hat mir viel Ärger erspart.
