MySQL connector with MinGW and WxWidgets
Posted by: Simon Ferber

Hello,

it seems that my former posting from friday isn't in the forums. Thus here is a new.

I need to write a Windows GUI applcation with MinGW/Cygwin which acts as a MySQL database client. As far as I understood I have to use the conncetor c/c++ and can't use neither from the binaries but have to compile them myself. Latter is what gives me headaches since more than a week now. The combination seem to be rather rare and there are just a few instruction (http://forums.mysql.com/read.php?117,426293,426927 and http://forums.mysql.com/read.php?117,425191,425191#msg-425191), but neither works. I've tried with MinGW, Cygwin and MSYS.

Latter instructions says: "Compiling mysql connector c++ works analogous to mysql connector c except that mysql_config needs to be in PATH for the configuration to work." Well, despite of the issue that the conncetor C doesn't build, there is no "mysql_config" on Windows. I have a "mysql_config.pl" only which doesn't seem to be compatible. In addition "boost" is needed but that is only a minor issue.

Here is what happens when I try to build the c++ connector...

It is pretty frustrating that neither instructions works. I even tried different combinations of MinGW/MSYS and their versions.

Any idea or is there a more recent manual?

Best
Simon
