• Understanding C++ error messages

The following simple Linux command can be extremely useful to understand the occasionally cryptic C++ error messages. The All C++ and Java function names are encoded into a low-level assembly label (this process is known as mangling).

Usage:

For example,

returns

which refers to the destructor of my param class.
