Re: Unknown host error when using Connector/C++

[Lawrin Novitsky]

Hello,

/MDd and /MD are basically the same - they result in linking of debug or non-debug version of the library.

Since it didn't help - could you please provide more info? Source you already has given, so project file or make file, or your build command line. And the same for mysql c++ driver.

it looked like your example application were linked against different crt lib. And driver is built (by default) w/ /MD. But since that didn't help... What else could i think of is maybe it finds "wrong" dll (e.g. from older installation).

I could build from your source with:

cl -EHsc -I"./" -I"./driver" forumUser.cpp /MD /link "driver/release/mysqlcppconn.lib"

and it runs fine (i put file w/ your source to the root of mysql c/c++ distribution; for running I copied driver dll to the same folder)
