I've been working for some time with php and mysql. I've always been curious, and am finally starting to play with C. I downloaded Paul DuBois' sample "Chapter 6: The MySQL C API".
I am running Mac OS X 10.2.4. I am running mysql version 3.23.54-max. I followed the instructions in the sample chapter to get the sample1.c program to compile.
I ran "mysql_config --cflags" and "mysql_config --libs" to get the right gcc flags. So I ended up with:
% gcc -c -I'/Library/MySQL/include/mysql' client1.c
When I execute that command, get a terminal full of compile errors (extra line breaks added):
% gcc -c -I'/Library/MySQL/include/mysql' client1.c
/Library/MySQL/include/mysql/mysql.h:127: undefined type, found `MEM_ROOT' /Library/MySQL/include/mysql/mysql.h:168: undefined type, found `MEM_ROOT' /Library/MySQL/include/mysql/mysql.h:184: undefined type, found `MEM_ROOT'
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
In file included from client1.c:4: /Library/MySQL/include/mysql/mysql.h:127: parse error before "MEM_ROOT"
(and then about 40 more)
The top of the client1.c file looks like this:
/* client1.c - connect to and disconnect from MySQL server */ #include <my_global.h> #include <mysql.h>
Try changing this to:
/* client1.c - connect to and disconnect from MySQL server */ #include <my_global.h> #include <my_sys.h> #include <mysql.h>
and let me know what happens.
So, can anyone tell me what I need to do to compile a simple C program on MacOS X that can connect to a MySQL database? (BTW, I am aware of the Cocoa framework for MySQL, but I am only interested in plain old command-line C for now.)
Thank you,
Beau
