dear Sir : MySQL 3.22 on my linux 486 PC seems work so good. when I compile a simple C API programe which catched from the MySQL tutorial, it chokes at the end of compile process . the programe is as follows: #include <stdio.h> #include <mysql.h> #define def_host_name NULL #define def_user_name NULL #define def_password NULL #define def_db_name NULL MYSQL *conn; int main(int argc,char *argv[]) { conn=mysql_init(NULL); mysql_real_connect( conn, def_host_name, def_user_name, def_password, def_db_name, 0, /*port defaut*/ NULL, /*socket default*/ 0); /*flag*/ mysql_close(conn); exit(0); } I compile as follows: gcc -o client my_simplest_prog -I/home/MySQL/MySQL/include \ -L/home/MySQL/MySQL/lib \ -lmysqlclient then I get : /home/MySQL/MySQL/lib/libmysqlclient.a(my_open.o)In function 'my_open': my_open.o(.text+0x14):undefined reference to 'open64' /home/MySQL/MySQL/lib/libmysqlclient.a(mf_format.o)In function 'fn_format': mf_format.o(.text+0x201):undefined reference to '__lxstat64' /home/MySQL/MySQL/lib/libmysqlclient.a(my_open.o)In function 'my_open': my_open.o(.text+0x21):undefined reference to 'fopen64' nothing left to do with the situation, I beg your help. anyway I'm a newcomer. thank you very much. please send message to [EMAIL PROTECTED] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
