pro*c 처음 사용하는데요,
어제 첨으로 컴파일하는거 대충 배우고,
make하는것도 배우고...(배웠다기보다는 그냥 배꼈죠, 의미도 잘 모르고...)
하여튼
소스만들고 make했는데 실행파일까지는 잘 생겼습니다.
그런데 실행파일을 실행하니까 Error가 나네요-.-
"세그멘테이션 결함(Segmentation Fault)(coredump)"이렇게...

소스는 아래와 같습니다.
#include <stdio.h>

EXEC SQL BEGIN DECLARE SECTION;
        int id;
        VARCHAR pay_yyyymm[10];
        VARCHAR ykiho[10];
        VARCHAR dbuserid[20];
        VARCHAR dbpassword[20];
EXEC SQL END DECLARE SECTION;

EXEC SQL INCLUDE sqlca;

void sql_error();

main()
{
        strcpy(dbuserid.arr,"GEIN10");
        dbuserid.len = strlen(dbuserid.arr);
        strcpy(dbpassword.arr,"GEIN10");
        dbpassword.len = strlen(dbpassword.arr);

        EXEC SQL WHENEVER SQLERROR DO sql_error();

        EXEC SQL CONNECT :dbuserid IDENTIFIED BY :dbpassword;

        printf("\nConnected to ORACLE as user: %s\n",dbuserid.arr);

        while(1){
                printf("\nEnter ID number (0 to quit): ");
                scanf("%d",&id);
                if(id == 0) break;

                EXEC SQL WHENEVER NOT FOUND GOTO notfound;

                EXEC SQL SELECT pay_yyyymm,ykiho
                                INTO :pay_yyyymm, :ykiho
                                FROM tbgyaa01
                                WHERE rownum=1;
                
                printf("\n\n%s\t%s\n",pay_yyyymm.arr,ykiho.arr);

                continue;
                        notfound:
                                printf("\nNot a valid ID number try again.\n");
                }

                printf("\nexit...\n\n");

        EXEC SQL COMMIT WORK RELEASE;
        exit(0);
}

void sql_error()
{
        EXEC SQL WHENEVER SQLERROR CONTINUE;

        printf("\nORACLE error detected:\n");
        printf("\n%.70s\n",sqlca.sqlerrm.sqlerrmc);

        EXEC SQL ROLLBACK WORK RELEASE;
        exit(1);
}

makefile은
PROC = proc
CC = cc
CFLAGS = -O2

INCLUDE = -I$(ORACLE_HOME)/precomp/public
LIBS = -L$(ORACLE_HOME)/lib -lclntsh

TARGET = start1

$(TARGET): $(TARGET).pc
        $(PROC) $(TARGET).pc
        $(CC) $(CFLAGS) -o start1 $(TARGET).c $(INCLUDE) $(LIBS)

clean:
        rm -f $(TARGET).o $(TARGET).c $(TARGET)

이렇게 만들었고요...
빠른 답변 주심 감사하겠네요...
첨이라 아무것도 모르겠습니다.
