Makefile problem Options

[RoboCop]

Hello I've managed to grab the /linux_sdk folder needed to recompile RCBot2 Linux from RCBot2's older github. I have been using GCC Make command recently for the HLDS bots that needed fixed for HLDS SteamPipe servers. I'm not familiar with Xerces-c or any VS C++ project converters for Linux.

I figured those makefiles are more complicated than the makefiles for the HLDS bots that I've been trying to fix and optimise. Is it possible that those SRCDS addons as well as RCBot2 only works with older compilers like G++-4.2? Got any more hints on Linux compile for RCBot2 as well key tools or options to use, please?
