gdb日志文件格式

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。日志文件不是很可读。如何获取可读格式的日志文件

屏幕输出正常：

(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"
  }
}

日志文件的输出可读性不强：

您必须从某种IDE使用此功能，该IDE将打开

MI

（机器界面）。您看到的输出是为了方便其他程序进行解析而制作的，但不是为了供人使用

MI接口也可能影响

gdb.txt

log的格式，这可能是一个错误。请提出一个关于它的错误

---

作为一种解决方法，在IDE之外运行GDB以收集易于阅读的

GDB.txt

没错，我使用的是cgdb。当使用gdb时，日志文件就可以了。真不敢相信我在发帖之前没有试过！非常感谢@马蒂亚斯：很好，你发帖了。我也处于同样的情况
