Linux Compile error Options

[RoboCop]

Hello I've been trying to recompile RCBot2 for Linux on this new Linux Mint PC, but it seems that the gnu-i386 string headers based on "memset"

CODE

mint@mint-computer ~/Dropbox/src/rcbot2/linux_sdk $ make -f Makefile.rcbot2

Also I did some other experiments with RCBot like adding the newer MM:Source src code for compiling the RCBot2_Meta addon as well other stuff like trying to recompile RCBot on Clang and on GCC 5, but they seem to be only compatible on GCC 4.8 or 4.9. I did try to add a GCC Toolchain for Clang but I think I may of missed a step, but I don't have the full experience on using Clang.

I am posting my Github commit changes here below. As for Win32 RCBot2 binaries...they seem to be compiled fine on VS2017 using the VS2013 Compiler kit.
