gcore之后，如何查看栈信息

来源：互联网发布：遗传算法在液压系统编辑：程序博客网时间：2024/05/16 06:04

这里假设gcore文件a已经存在，如果不存在可以使用命令：gcore pid，生成一个，下面简要描述过程：

1.gdb binary a

2.gdb中设置log文件的位置，同时打开log;
set logging file /tmp/test.txt
set logging on

3.使用 thread apply all bt输出所有的堆栈
Thread 2 (Thread 0x41ec5940 (LWP 7312)):
0 0x00002b6370d241c0 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0
1 0x00002aaab3bbf229 in ?? () from /usr/lib64/libnspr4.so
2 0x00002aaab3bbfe69 in PR_WaitCondVar () from /usr/lib64/libnspr4.so

7 0x00002b637120d9ad in clone () from /lib64/libc.so.6

Thread 1 (Thread 0x2b63731b4360 (LWP 4718)):
0 0x00002b6371206b42 in select () from /lib64/libc.so.6
1 0x00002b6370b10d25 in apr_sleep () from /usr/lib64/libapr-1.so.0
2 0x00002b636f242315 in ap_wait_or_timeout ()
3 0x00002b636f24b79e in ap_mpm_run ()
4 0x00002b636f225fd8 in main ()

接下来就可以在/tmp/test.txt文件中进行信息查找了
