Halloechen
ich hab da ein Problem mit einem C-Programm das unter Windows funktioniert, jedoch unter Linux Probleme macht :
Das Programm ist dazu gedacht xml-Dateien zu erzeugen. Dazu werden einige Begriffe (ANSI- oder UTF8-Format) mit einer mysql-Datenbank(Daten in UTF8-Format) abgeglichen, daher die Notwendigkeit der Zeichenumwandlung.
Hier die Fehlermeldungen
diss_to_xml.cpp: In function `int main(int, char**)':
diss_to_xml.cpp:79: error: invalid conversion from `char*' to `unsigned char*'
diss_to_xml.cpp: In function `int fakultaet_aus_Mysql(char*, char*)':
diss_to_xml.cpp:112: error: `CP_UTF8' undeclared (first use this function)
diss_to_xml.cpp:112: error: (Each undeclared identifier is reported only once for each function it appears in.)
diss_to_xml.cpp:112: error: `WCHAR' undeclared (first use this function)
diss_to_xml.cpp:112: error: `MultiByteToWideChar' undeclared (first use this function)
diss_to_xml.cpp:113: error: `CP_ACP' undeclared (first use this function)
diss_to_xml.cpp:113: error: `WideCharToMultiByte' undeclared (first use this function)
diss_to_xml.cpp: In function `int fach_aus_Mysql(char*, char*, char*)':
diss_to_xml.cpp:147: error: `MultiByteToWideChar' undeclared (first use this function)

und der entsprechende Soure-code :

wuerde mich ueber jeden hilfreichen Tip freuen.
