Hello, Ian I'm developing a mechanism in the gcov, instead of writing the file gcda (in file gcov-io.c), it sends the information to a host via a socket. The host generates gcda. So I'd like to get the IP at compile time to use when sending the data through the socket. But from what you said, the variable is only available at compile time, which is not my case. > To be clear, this will give you a new variable in the compiler itself. > It will not give you a variable in the gcov program, nor in the program > you are compiling.

What kinds of mechanisms I can develop to use this variable when sending information?
