gdb日誌文件格式

Question

當我在gdb中使用set logging on時，日誌文件的輸出格式與我在終端屏幕上看到的格式不同。日誌文件不可讀。我怎樣才能獲得可讀格式的日誌文件？

輸出到畫面精美：

(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" 
    } 
} 

輸出到日誌文件不是很有可讀性：

您必須使用這個從某種IDE的，果然在MI（機器接口）上。您看到的輸出是爲了便於其他程序解析而製作的，但不適合人類消費。

這可能是一個錯誤，MI接口也會影響gdb.txt日誌的格式。請提交一個關於它的錯誤here。

作爲一種解決方法，在IDE之外運行GDB以便收集易於閱讀的文章gdb.txt。
