C GDB重置配置
编辑: 我试图用C GDB重置配置,c,gdb,valgrind,C,Gdb,Valgrind,编辑: 我试图用sudo-apt-get-autoremove-gdb重新安装gdb,然后sudo-apt-get-install-gdb。仍然不能解决这个问题 原始问题: 所以最近,也就是大约3小时前,我安装了valgrind来检查内存泄漏,现在我尝试编译一些东西并运行GDB(终端或Eclipse),所有malloc/calloc命令也在逐步调试 测试文件: #include<stdio.h> #include<stdlib.h> typedef struct tem
sudo-apt-get-autoremove-gdb
重新安装gdb
,然后sudo-apt-get-install-gdb
。仍然不能解决这个问题
原始问题:
所以最近,也就是大约3小时前,我安装了valgrind
来检查内存泄漏,现在我尝试编译一些东西并运行GDB(终端或Eclipse),所有malloc
/calloc
命令也在逐步调试
测试文件:
#include<stdio.h>
#include<stdlib.h>
typedef struct tem{
int i;
} name;
int main() {
name *t;
printf("EASD");
t = malloc(sizeof(name));
return 0;
}
编译时使用:
cc-g-o asd a.c
使用调试:
gdb asd
终端:
(gdb) run
Starting program: /home/userName/workspace/as/asd
Breakpoint 2, main () at a.c:10
10 t = malloc(sizeof(name));
(gdb) step 18442
Single stepping until exit from function _fini,
which has no line number information.
Single stepping until exit from function __do_global_dtors_aux,

EASD33 ../sysdeps/unix/sysv/linux/_exit.c: No such file or directory.
(gdb) step
[Inferior 1 (process 6621) exited normally]
无断点的GDB:
(gdb) run
Starting program: /home/userName/workspace/as/asd
EASD[Inferior 1 (process 6631) exited normally]
我的问题是,如何重新配置/重置GDB以跳过以前的标准库函数
从另一台计算机:
(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
Starting program: /home/userName/a.out a.out
warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
Breakpoint 1, main () at a.c:10
10 printf("EASD");
(gdb) step
11 t = malloc(sizeof(name));
(gdb) step
12 return 0;
(gdb) step
13 }
(gdb) step
0xb7e067c3 in __libc_start_main () from /usr/lib/libc.so.6
现在,由于GDB7.4,我不得不使用
(gdb)跳过文件malloc.c
我希望能找到其他方法来恢复GDB以前的功能,这样我就不必手动添加所有标准库源文件(我尝试了
(GDB)跳过文件stdlib.h
,只针对那些想知道的人)你确定这与valgrind有关吗?请参阅。@dbrank0类似,谢谢您的链接,但我想知道是否有一种方法可以让它像以前那样工作。我安装了valgrind
,接下来我知道的GDB
开始工作。我之前没有使用过valgrind
,但我看不出有任何问题(目前)。我用它来检查内存泄漏。
