C GDB报告（带有list和frame命令）不列出行号

我正在使用gdb来找出我的程序中哪里有SEGFULT。但是，我的GDB报告没有指定行号，它只是命名函数

root@brute-force-compute:~# gcc -g -pthread program.c -o program -lmysqlclient
root@brute-force-compute:~# gdb program


(gdb) run --journal --day "Tuesday" --job "iOS" --client "SEAS"
Starting program: /root/serapis --journal --day "Tuesday" --job "iOS" --client "SEAS"

编辑：使用

-g

标志编译

gcc program.c -o program -g -lmysqlclient -l pthread
gdb program
(gdb) run --journal --day "Tuesday" --job "iOS" --client "SEAS"
Program received signal SIGSEGV, Segmentation fault.

第一次尝试：

gcc program.c -o program -lmysqlclient -l pthread
gdb program 
(gdb) run --journal --day "Tuesday" --job "iOS" --client "SEAS"
Starting program: root/program --day "Tuesday" --job "iOS" --client "SEAS"

#2  0x00000000004086d4 in main ()

在

main

中，我执行以下操作：

if(strcmp(argv[1], "--journal") == 0){
        printf("\nInitializing single integral machine..\n\n");
        char * template = argv[2];
        init_journal(day, job, client);
    }

其中，日期、作业、客户机在

main

中的设置较早，如下所示：

   if(strcmp(argv[i], "--day") == 0){
        day = argv[++i];
   }

我看了不同的帖子，在这里我看到我应该改变在gdb中输入命令行参数的方式：

run $(--journal --day "Tuesday" --job "iOS" --client "SEAS")

然后我得到报告：

Program received signal SIGSEGV, Segmentation fault.
__strcmp_sse2_unaligned () at ../sysdeps/x86_64/multiarch/strcmp-sse2-unaligned.S:31
31  ../sysdeps/x86_64/multiarch/strcmp-sse2-unaligned.S: No such file or directory.

gcc program.c-o program-lmysqlclient-l pthread

此命令生成不带调试信息的程序。这在其他方面也是不正确的

你想要：

gcc -g -pthread program.c -o program -lmysqlclient

我看了不同的帖子，在这里我看到我应该改变在gdb中输入命令行参数的方式：

run $(--journal --day "Tuesday" --job "iOS" --client "SEAS")

run$（-journal--day“星期二”--job“iOS”--client“SEAS”）

---

这完全是假的命令行。您不应该这样做。

使用-g flag编译当我使用该行编译时，仍然没有得到任何调试信息。@Matt您可能弄错了。在使用

-g

编译的程序上显示

的输出，其中
