Question

当我在gdb中使用set logging on时，日志文件的输出格式与我在终端屏幕上看到的格式不同。日志文件不是很易读。如何以可读格式获取日志文件？

输出到屏幕很好：

(gdb) p foo
$1 = {
  static npos = 18446744073709551615,
  _M_dataplus = {
    <std::allocator<char>> = {
      <__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data fields>},
    members of std::basic_string<char,std::char_traits<char>,std::allocator<char> >::_Alloc_hider:
    _M_p = 0x601028 "Hello World!\n"
  }
}

输出到日志文件的可读性不高：

您必须在某种IDE中使用它，这会打开MI（机器界面）。您看到的输出是为了便于另一个程序解析，但不供人类使用。

MI接口也可能影响gdb.txt日志格式的错误。请提交有关它的错误here。

作为一种解决方法，在IDE外部运行GDB以收集易于阅读的gdb.txt。
