一个cgi程序（只是连接数据库）直接运行可以，被apache当cgi调用却老报500异常

一个cgi程序（只是连接数据库）直接运行可以，被apache当cgi调用却老报500错误
一个cgi程序（只是连接数据库）直接运行可以，被apache当cgi调用却老报500错误

代码如下：

C/C++ code

EXEC SQL BEGIN DECLARE SECTION;
    char    d_acDBNAME[ 64 + 1] = "calvin@127.0.0.1:5432" ;
    char    d_acDBUSER[ 64 + 1 ] = "calvin" ;
    char    d_acDBPASS[ 64 + 1 ] = "calvin" ;
EXEC SQL END DECLARE SECTION;

#define SQLCODE        sqlca.sqlcode
#define SQLSTATE    sqlca.sqlstate

int main()
{
    EXEC SQL
        CONNECT TO        :d_acDBNAME
        USER            :d_acDBUSER
        IDENTIFIED BY    :d_acDBPASS ;
    
    if( SQLCODE )
    {
        printf("Content-type: text/html\r\n\r\n");
        printf( "连接失败\r\n\r\n" );
    }
    else
    {
        printf("Content-type: text/html\r\n\r\n");
        printf( "连接成功\r\n\r\n" );
    }
    
    return 0;
}

makefile里这样写：
%.o : $(SQCPATH_SQC)\%.SQC
$(CC) -E -I$(CPATH_h) $(CFLAGS) -x c $(SQCPATH_SQC)\$*.SQC > $*.sqec
$(SQCP) $*.sqec
$(CC) -c -I$(CPATH_h) $(CFLAGS) $*.c -o $*.o

testdb.cgi : testdb.o
$(CC) -o $@ testdb.o -LD:/Work/PostgreSQL8.3/lib -lecpg

直接运行显示：
D:\Work\home\calvin\www\query_account\cgi-bin>testdb.cgi
Content-type: text/html

连接成功


在ie里被apache当cgi调用却返回500错误：
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@netitanium.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

apache日志error.log有：

高手帮忙解决，先谢谢啦


------解决方案--------------------
你生成的header不正确么
------解决方案--------------------
建议LZ把打印Http文件Header消息的那句话拿到最前面去。
EXEC SQL BEGIN DECLARE SECTION;
char d_acDBNAME[ 64 + 1] = "calvin@127.0.0.1:5432" ;
char d_acDBUSER[ 64 + 1 ] = "calvin" ;
char d_acDBPASS[ 64 + 1 ] = "calvin" ;
EXEC SQL END DECLARE SECTION;

#define SQLCODE sqlca.sqlcode
#define SQLSTATE sqlca.sqlstate

int main()
{
printf("Content-type: text/html\r\n\r\n");
EXEC SQL
CONNECT TO :d_acDBNAME
USER :d_acDBUSER
IDENTIFIED BY :d_acDBPASS ;

if( SQLCODE )
{

printf( "连接失败\r\n\r\n" );
}
else
{
printf( "连接成功\r\n\r\n" );
}

return 0;
}
