"GDB is a source-level debugger, capable of breaking programs at any specific line, displaying variable values, and determining where errors occurred. Currently, gdb supports C, C++, D, Objective-C, Fortran, Java, OpenCL C, Pascal, assembly, Modula-2, Go, and Ada. A must-have for any serious programmer. . This package contains gdbserver. Install this to debug remotely from another system where GDB is installed."
