Sometimes I have troubles trying to de-code Visual Studio linker errors with weird symbols. There is a nice online tool https://demangler.com/ that works for GCC and MSVC symbols. The basic idea is that it transforms the C++ linker symbols like ?foo@MyClass@@IAEXV?$vector@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@V?$allocator@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@2@@std@@@Z to a relatively readable C++ code. I think it is nice to have this tool integratated into Visual Studio as extension.

Here you can see mangled symbols.

After enabling demangled build output symbols are readable.
