Read the FAQ and the docsI don 't know if this will solve your problems but it is the most suggested
solution in case of linking problems
include mysqlpp.dll in your project folder and visual studio will be able
to find it.
Hi
I have a problem compiling a project with mysql++.
First I installed MySQL 5.0 for Windows (WinXP SP2 here ^^). Then I downloaded mysql-5.0.45-win-src and compiled it. All goodie so far. Then I Jonathan Wakely wrote

I 'm pretty sure the whole create-on-demand strategy used with FieldNames

MySQL++ isn 't thread-safe today [*] and it will never be truly
"thread-safe " in the sense that any thread can do anything it likes at

On any machine with virtual memory I agree. If you 've run out of

That way when the rest of the compilers come out with their TR1
implementations you aren 't necSorry Robert I didn 't see your post.
Warren seems to have generated a nice discussion. Excellent.

not mysql++. If this is correct then this is no the place for that
question.

From Maarten SchrijveSorry I wasn 't actually particularly clear with the whole transform
thing - it would need to be possible either at field level *or* object
level. LocaliseDate would therefore need std string

1. It 's not thread-safe. You can 't reference a single object from multiple
threads. To be able to do so incrementing and decrement |
