It appears the compiler doesn't know where to find the
#include'd files. There is probably a compiler option to
tell it where to look, something like

gcc -I c:/mysql7.2/include ... yourfile.c ...

The details will vary depending on exactly where the include
files are located.

That's more a question for the comp.databases.mysql newsgroup.

Have you read and reviewed the MySQL API documentation? Take a look at
http://dev.mysql.com/doc/refman/5.0/en/c.html
and especially at the example code in
http://dev.mysql.com/doc/refman/5.0/...t-execute.html

That's a good way of getting things working temporarily. But it's not a
long term solution. The reason is that the code won't compile when moved to
a machine with a different directory structure.
Eric Sosman's answer, which was to fiddle about with include paths in the
compiler's settings, is the right approach. If you're using a commandline
com puiler, the option is usually -I. If you're compiling from an IDE,
search the menus for "settings", "configuration", "compiler options" or
tools like that. An option to set include paths will be in there somewhere.

If it's on the OP's system mysql_config is a useful tool to help with
this. "mysql_config --include" or "mysql_config --cflags" will add the
correct path to his compiler command line. I don't know if mysql with
MingW would include it but ...

Run from a bash term :
gcc -W $(mysql_config --cflags) code.c -o code $(mysql_config --libs)
