mysql++1.7.1 vc++6 compile errors

2006-03-13 Thread Keith Lee 
Hi

I am using visual studio C++ 6, with SDK, my mysql database is 4.1.18, i 
downloaded mysql++ 1.7.1 as this is the compatiable version for vc++6. 

the example program compiles and runs. when i go to make my own project i use 
the wizard and create a basic dialog MFC app. at the top of the main cpp file i 
add #include mysql++ and then in the program call Connection 
con(login,localhost,root,abc);

in the mysql++ download there is many lib and include folders, i have copyied 
the contents of these in the the vc++6 include and lib folders. 

when come to compile i get many errors as seen below. please help

mysql++1.7.1 vc++6 compile errors

2006-03-13 Thread Keith Lee 
thanks for the reply Jason, i have now added mysql++.lib to the linker and also 
copyied the libmysql.dll to the system folder. the program complies now with a 
few performance warnings but no errors.

there is one link error
LINK : warning LNK4098: defaultlib LIBC conflicts with use of other libs; use 
/NODEFAULTLIB:library
In the settings if i do as it says above, i get over 200 errors!! so i revert 
back.


i have the simple code below but when the program is ran, the first message box 
comes up and then the program crashes

MessageBox(test1);
Connection con(login, localhost, root, abc);
MessageBox(test2);

the crash error is abnormal program termination

if i use the example console code that comes with mysql++ 1.7.1 i get the 
following error at run time.
Error: Client does not support authentication protocol requested by server; 
consider upgrading MySQL client

as i already said, i am running mysql++1.7.1 and mysql 4.1.18 and vc++6

please help
