OS X Install problem

[Anonymous]

I am getting the following error message :

I installed the developer tools after installing mySQL, not sure if this is the cause of the problem.

Any help would be much appreciated.

When compiling 1.2.2c1 for OS X 10.5 (latest Developer Tools), and building against mysql 5.1.3 osx10.5, I got a similar error:

The problem was not in mysql.h:47 but in _mysql.c:37-40
35: #include "my_config.h"
36: #endif
37: #ifndef uint
38: #define uint unsigned int
39: #endif
40: #include "mysql.h"
41: #include "mysqld_error.h"
42: #include "errmsg.h"

The problem here came up because sys/types.h does not check the typedef for uint. The solution was to move the define statement below the include statement for "msql.h":

include "mysql.h"

include "mysqld_error.h"

include "errmsg.h"

ifndef uint

define uint unsigned int

endif

and it built fine. This is not the right way to go about it -- if uint is not defined in sys/types.h gcc will error out in mysql.h. The correct fix should be to include sys/types.h first, then conditionally define uint and finally include "mysql.h":

include <sys/types.h>

ifndef uint

define uint unsigned int

endif

include "mysql.h"

include "mysqld_error.h"

include "errmsg.h"

Which also works fine.

Cheers,
