Message1. MySQL functions Can't run with wxWindows?
Posted by: mooncake 2003-12-18 21:42:13
    I can compile it with console mode, but, i can't compile it with wxWindows?

it always prompt me this error message:

116 C:HomeCompilerDev-Cppincludemysqlmysql_com.h
'SOCKET' is used as a

180 C:HomeCompilerDev-Cppincludemysqlmysql_com.h
`SOCKET' was not

180 C:HomeCompilerDev-Cppincludemysqlmysql_com.h
parse error before `,'

main error focus on:

my_socket fd;                /* For Perl DBI/dbd */
struct sockaddr;
int my_connect(my_socket s, const struct sockaddr *name, unsigned int namelen,
          unsigned int timeout);

what happen?  Is that can't use mySQL functions in wxWindows?

Thank you.

Please post your full compile log next time. "'SOCKET' is used as a" is not a very detailed information :)
Maybe set -fmessage-length=0 as a general compiler option so that the errors and warnings don't get cutted.

Judging from the errors I'd say that it's a problem how my_socket was defined. Under Windows where _WIN32 is defined it is SOCKET. This seems to cause an error when using with wxWindows. I tried the following and it seems to work:
1. Open mysql.h
2. Find line 49 (#ifdef __WIN__)
3. Change it to #if (defined(__WIN__) && !defined(__GNUWIN32__))
4. See that __GUNWIN32__ is defined in your compiler options (-D__GNUWIN32__)
5. link to libmysql.a as usual.

As I said I ran some simple test (init - connect - error message - else close connection) and it seems to work. This is surely not the best way to do it. I'm open to any suggestions (maybe using namespaces would be better?).

If it was hard to write, it should be hard to read!- Do. Or do not. There is no try!

it gonna ok now, coz i change my_socket s to sockaddr s

is that mysql functions only have fetch_row and no have fetch_array?

becuase, i dont like to use like this:  row[0] to get the data, and i want to pass the data field and get the data....

Thank you...
