我在看记录输出并一直在尝试这个特定的命令 -
set logging overwrite on
AFAI 明白了,该命令应该覆盖 gdb.txt 的内容,但事实并非如此。那里有错误或者我没有正确理解含义/语法。
我在跑步 -
[$] gdb --version

这是在 Debian 上进行的测试。
并没有告诉我太多,但我不是 gdb 专家,甚至不是中级用户。如果有人知道引用上述行为的错误,请分享,或者如果我缺乏理解,也请分享。
更新 -
确切的命令是 -
$ gdb qbittorrent
(gdb) set logging overwrite on
(gdb) set pagination 0
(gdb) run
当应用程序通过 - 挂起/崩溃时
QXcbConnection: XCB error: 3 (BadWindow), sequence: 16699, resource id: 14227177, major code: 40 (TranslateCoords), minor code: 0
pure virtual method called
terminate called without an active exception
Thread 1 "qbittorrent" received signal SIGABRT, Aborted.
__GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51
51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.
我做了必要的事情 -
(gdb) bt
(gdb) bt full
(gdb) thread apply all bt
现在我期望使用overwrite on
命令 gdb 会覆盖当前会话中的 gdb.txt 内容并覆盖文件的时间戳,但两者都没有发生。幸运的是,我没有关闭会话,因此能够将调试会话内容复制到维护者和上游,以便他们可以仔细查看发生的情况。
我很好奇/不明白为什么它没有进行更改,或者我理解错误。
答案1
您错过了实际的日志记录 ( set logging on
):
(gdb) set logging overwrite on
(gdb) set logging on
