编译时出现错误：
"alarm.c", line 708: Error: Too many arguments in call to "sqlorat()".
"alarm.c", line 719: Error: Too many arguments in call to "sqlcxt()".
对应的alarm.c部分为：
693 void sql_error(char *msg)
694 {
695 char err_msg[512];
696 size_t buf_len, msg_len;
697 /* EXEC SQL WHENEVER SQLERROR CONTINUE; */

二楼我贴上Makefile代码 |
