Linux中Oracle 11g Proc*C开发环境搭建

使proc预编译命令可用：

[karihou@bogon ~]$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
export ORACLE_BASE=/home/karihou/app/karihou
export ORACLE_HOME=/home/karihou/app/karihou/product/11.2.0/dbhome_1
export ORACLE_SID=orcl
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:$LD_LIBRARY_PATH

 

配置pcscfg.cfg文件:

[karihou@bogon admin]$ view pcscfg.cfg
sys_include=($ORACLE_HOME/precomp/public,/usr/include,/usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/include,/usr/lib/gcc/x86_64-redhat-linux/4.1.1/include,/usr/lib64/gcc/x86_64-suse-linux/4.1.2/include,/usr/lib64/gcc/x86_64-suse-linux/4.3/include,/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include)
ltype=short
define=__x86_64__
#以下为手动添加环境变量
include=($ORACLE_HOME/precomp/public)

测试源码：

[root@bogon ~]$ cat login.pc
#include <stdio.h> 
#include <stdlib.h>  
#include <string.h>  
  
EXEC SQL INCLUDE sqlca;  
  
EXEC SQL BEGIN DECLARE SECTION;  
varchar username[20];  
varchar password[20];  
EXEC SQL END DECLARE SECTION;  
  
int  
main(void)  
{  
    strcpy(username.arr, "karihou");  
    username.len = strlen("karihou");  
    strcpy(password.arr, "1");  
    password.len = strlen("1");  
  
    EXEC SQL CONNECT :username IDENTIFIED BY :password;  
    if(sqlca.sqlcode == 0){  
        printf("login success\n");  
    }else{  
        printf("login failed\n");  
    }  
  
    exit(0);  
}
