I'm writing a Swift application for MacOS that makes use of a C/C++ dylib from a third party to interact with a film scanner. The application uses dlopen() & dlsym() to discover and call the C wrapper function for the C++ implementation. Overall this works, but I've run into the following wall while debugging an issue within the dylib itself.
While debugging I want to examine std::list <T> structures in memory by address. I am stopped deep inside the C++ code, and from what I've googled, printing STL variables is possible through `frame variable`, however for all of the functions within the dylib, `frame variable` doesn't find any variables. I've tried using `expr -l c++ -- reinterpret_cast<std::list<int>>($rdi)`, however this just returns the error: "use of undeclared identifier 'std'". Is there a way to cast an arbitrary address as an STL type, and print it out in lldb? I know it's possible to write a custom command in python to do this, but I'd really rather not write something from scratch if the functionality already exists in lldb. Thank you, -David M.
