Optionen für Meldungen
Nach oben zu Befehlszeilenhilfsprogramme - Index
Mit der Option -w legen Sie die Meldungsoptionen für den C++-Compiler (BCC32.exe) fest:
- Um eine bestimmte Warnmeldung zu aktivieren, geben Sie die Option -w mit einem ein- bis dreibuchstabigen Meldungsbezeichner ein.
- Um die Warnmeldung zu deaktivieren, geben Sie die Option -w- mit einem ein- bis dreibuchstabigen Meldungsbezeichner ein.
Beispiele
Um alle Warn- und Fehlermeldungen anzuzeigen, geben Sie in Ihrem BCC32-Befehl die Option -w an:
>bcc32 ... -w
Um die Anzeige der Warnung "Unterschiedliche Zeiger auf verschiedene 'char'-Typen" (Option: ucp, Voreinstellung: AUS) zu aktivieren, geben Sie in Ihrem BCC32-Befehl das folgende Flag an:
-wucp
Um die Anzeige der Warnung "Deklaration wird ignoriert" (Option: dig, Voreinstellung: EIN) zu deaktivieren, geben Sie in Ihrem BCC32-Befehl das folgende Flag an:
-w-dig
Zum Anzeigen der Hilfe zu den Meldungscodes geben Sie einen Compiler-Befehl ein, der nur die Optionen -h und -w enthält:
C:>bcc32 -h -w
{InstallPath\bin>bcc32 -h -w
