求教Pro*C的问题,请大侠指教!

有程序如下：
#include<stdio.h>

EXEC SQL include sqlca;

main()
{
   char *ConnectStr="scott/tiger";
   char Ename[30];
   float  Salary;

   EXEC SQL connect :ConnectStr;

   for(;;)
   {
      printf("lease input employee name(or \"exit\"):\n");
      scanf("%s", Ename);
      if(strcmp(Ename, "exit")==0)
         break;

      EXEC SQL select sal into :Salary
               from emp
               where ename=:Ename;

      printf("His/her salary is $%.0f.\n", Salary);
   }
}

在使用proc编译时提示如下:
[oracle@localhost proc]$ proc iname=proc.pc oname=proc.c

不知是怎么回事。
在将第一条语句删除后可能生成proc.c文件并生成以下三个文件：
tpAwYcs0.dcl
tpfpXZit.cod
tpS03M9V.cud

但在用gcc编译proc.c文件时失败并提示如下：
/tmp/cccs1dtd.o: In function `main':
/tmp/cccs1dtd.o(.text+0x15e): undefined reference to `sqlcxt'
/tmp/cccs1dtd.o(.text+0x361): undefined reference to `sqlcxt'
collect2: ld returned 1 exit status

小弟反复查看程序也找不出什么原因。
请大侠指教，不胜感激!　　　　　　

main 函数前面写为
#include <sqlca> 就可以了，不需要包含 EXEC SQL

你先试试吧，肯定还有其他错误，对了，你的sql语句
不长，最好写在一行　　　　　　

是

include <sqlca>


编辑时好好的，怎么传上去变了　　　　　　

看看这样能不能传对

"include <sqlca>"


不行就看这个

include 尖括号sqlca尖括号　　　　　　

环境变量设置的不对?比如ld_library_path等一些变量。

因为此现象在RH6.2和RH7.3下都会出现。
我只设置
LD_LIBRARY_PATH=$ORCLE_HOME/lib
是不是需要其它的一些设置？
