MySQL++ - Welche lib?
-
Hi!
Ich versuche gerade ein Konsolenprogramm in VC ++ 2003 .NET zu schreiben
jetzt bekomme ich folgende Linkerfehler:------ Build started: Project: mysqltest, Configuration: Debug Win32 ------ Linking... mysqltest.obj : error LNK2019: unresolved external symbol "public: __thiscall mysqlpp::Connection::~Connection(void)" (??1Connection@mysqlpp@@QAE@XZ) referenced in function _main mysqltest.obj : error LNK2019: unresolved external symbol "public: class mysqlpp::Query __thiscall mysqlpp::Connection::query(void)" (?query@Connection@mysqlpp@@QAE?AVQuery@2@XZ) referenced in function _main mysqltest.obj : error LNK2019: unresolved external symbol "public: __thiscall mysqlpp::Connection::Connection(char const *,char const *,char const *,char const *,bool)" (??0Connection@mysqlpp@@QAE@PBD000_N@Z) referenced in function _main Debug/mysqltest.exe : fatal error LNK1120: 3 unresolved externals Build log was saved at "***" mysqltest - 4 error(s), 0 warning(s) ---------------------- Done ---------------------- Build: 0 succeeded, 1 failed, 0 skippedso...
jetzt frage ich euch, welche lib muss ich linken?
-
die mysql++ lib. nicht nur inkludieren, sondern auch linken.
-
wenn ich das mache, dann bekomme ich noch mehr linker error

Schau mal auf meine Seite. Da gibt es auch eine Wrapper mit dem einige von hier sehr zufrieden sind.
Die Header ist selbsterklärend.
