当我在 cgdb 中踏入这一行时
if (cfgFile.good()) //Settings:cpp:31
std::cout << "File load succeeded" << std::endl; //Settings:cpp:32
我收到这个错误
(gdb) run

显然，在使用 cgdb 指定它们后，它看不到我的系统头文件
dir -isystem path/to/gcc/system/headers
根据错误，它正在basic_ios.h寻找
/build/gcc/src/gcc-build/i686-pc-linux-gnu/libstdc++-v3/include/bits/basic_ios.h
但是该目录在我的文件系统中不存在，但我确实在这些目录中有该文件
/usr/include/c++/6.2.1/bits/basic_ios.h
/usr/lib/gcc/i686-pc-linux-gnu/5.4.0/include/c++/bits/basic_ios.h
我怎样才能让 cgdb 也单步执行系统头文件。我必须在我的 cmake 文件中做些什么吗？我确实使用调试标志构建了我的程序，所以出了什么问题？
