I'm trying to debug a program written in c++ using gdb from vscode.
When the debugger calls the function ifstream() from the header fstream, it's unable to find the header file because gdb is looking for it on the directory /build/gcc/src/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/include/ , which doesn't exist and results in wrong code execution.
I've fixed this by using the command directory /usr/include/c++/10.2.0/ on gdb from the terminal, but this doesn't seem to fix the problem when I use gdb from vscode.
Thanks in advance.
Finally, I have solved this problem.
When gdb is executed, it looks for a configuration file called .gdbinit on the user's home directory (Unix systems). To give gdb the right header's directory it's as easy as put the command source {your header's directory} on the file previously mentioned.
If Visual Studio doesn't recognice c/c++ functions, just put the header's location on your settings.json file ("C_Cpp.default.includePath": ["your header's directory"].
