I'm trying to implement basic socket program in C which parses HTTP GET requests for now, in `parse_http_req` function I've declared `char* line;` and after `strncpy` call `line` contains 1st line of HTTP request data.

Remove the `bin` from MAVEN_HOME. When the path is building you add `bin` again, then the path the machine is looking for is
```none

which is wrong. |
This is more a hint than a question:
The goal is to parse a command line **AND** create a useful *usage* message
