Connettore Mysql/C++ per Windows 2010 Express non compilato

Question

SOLUZIONE: Ho deciso di fare una guida passo passo per persone che hanno gli stessi problemi. Non so se questo risolve completamente tutto, ma ti consente di compilare lo snippet di codice che fornirò. Se ci sono errori si prega di commentare in modo da poterli risolvere. Questo ha lo scopo di aiutare coloro che hanno rinunciato per lo più a tentativi falliti, e per essere sinceri, l'intero processo avrebbe dovuto essere documentato. Ci scusiamo per il lungo post: P

STEP BY STEP FOR SETTING UP MYSQL CONNECTOR/C++ FOR 2010 MICROSOFT VISUAL C++ EXPRESS: 
FILES NEEDED: 
Windows x86 32 Bit ZIP: Connector/C++ -> http://dev.mysql.com/downloads/connector/cpp/ 
Windows X86 32 Bit ZIP: Connector/C -> http://dev.mysql.com/downloads/connector/c/ 
BOOST -> http://www.boost.org/users/download/ 

The reason why 62bit doesn't work is because you are using the express edition. After you have downloaded all those files, extract them. I keep mine in C (for ease of access). Now open up MVC++ 2010 EXPRESS. 
File -> New -> Project 
Win32 Console Application 
Next 
Check Empty project 
Finish 
Create your first .cpp. I call mine main.cpp 
Project -> Properties 
C/C++ -> General -> Additional Include Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include 
C/C++ -> General -> Additional Include Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\include\cppconn 
C/C++ -> General -> Additional Include Directories -> C:\boost_1_49_0 
Linker -> General -> Additional Library Directories -> C:\mysql-connector-c++-noinstall-1.1.0-win32\mysql-connector-c++-noinstall-1.1.0-win32\lib 
Linker -> General -> Additional Library Directories -> C:\mysql-connector-c-noinstall-6.0.2-win32\mysql-connector-c-noinstall-6.0.2-win32\lib 
The reason why we downloaded the Connector/C is because it has two files we need: libmysql.lib and libmysql.dll 
Linker -> Input -> Additional Dependencies -> mysqlcppconn.lib 
Linker -> Input -> Additional Dependencies -> libmysql.lib 

If you change to Release, youll have to enter in the information again. 
In your main.cpp place the following code and build it:

Si dovrebbe ottenere gli errori per int8_t. Fare doppio clic sul file config.h situato in: c: \ mysql-connector-C++ - noinstall-1.1.0-win32 \ mysql-connector-C++ - noinstall-1.1.0-win32 \ include \ cppconn \ config.h. Fare doppio clic per richiamarlo. Ora basta commentare tutti i typedef che dovrebbero esserci solo 8. Metti libmysql.dll (all'interno del Connector/C) e mysqlcppconn.dll (all'interno del Connector/C++) all'interno della cartella in cui il compilatore sta generando la tua build. Al termine, salva ed esegui.

Ho seguito le istruzioni su questo sito testualmente: http://blog.ulf-wendel.de/?p=215 Ma io sono ancora ottenere un errore di compilazione. Non sono nuovo a collegare le librerie o includere le directory, ma potrei usare un nuovo supereroe che ha creato applicazioni con mysql connector/C++ con 2010 express ... per fare un semplice esempio di KISS. Ho digrignato i denti tutto il giorno. Fonte Esempio: http://www.tidytutorials.com/2009/07/mysql-connector-c-example-windows-clexe.html (con il database modificato)

UPDATE: ho seguito anche questo: http://forums.mysql.com/read.php?167,492097,492097#msg-492097 Ho anche utilizzato il connettore c (build separato) con entrambi i test con ciascuna 64 C++, e, e 32 bit versioni (per un totale di 4 test). Ho scaricato boost e collegato. Il nuovo codice che sto usando pubblicherà qui di seguito che proviene dal sito web ufficiale di mysql. Entrambe le build producono gli errori SAME.

UPDATE 2: view_findpost_ p _1474626" > http://www.dreamincode.net/forums/topic/253647-question-regarding-connecting-to-mysql-50-using-visual-studio-2010/ page_ view _findpost_ p _1474626 Questo tipo sembra pensare che sia perché config.h è in conflitto con stdint.h su compilazione perché in config.h c'è un #typedef per int8_t. Ci deve essere una soluzione a questo. anche prendere qualsiasi altra libreria (gratuita) che possa connettersi a un database MySQL locale, ma sono davvero desideroso di capirlo per aiutare tutti fuori

Answer 1

Poiché ci sono un sacco di domande su C++ e sul connettore MySQL, ed è reall E 'difficile farlo funzionare, risponderò a questa domanda anche se è stato chiesto come un anno fa.

soluzione è piuttosto semplice, unica cosa che dovete fare è quella di commentare tutti i typedef di in cppcon file/config.h
