[RoboCop]

Well I am currently trying to fix and optimise some HLDS addons that seem to need looking at as well as finding a useful IDE that can have some useful extensions and helpful tools. I've been trying CodeLite as well using the useful wizard that allows me to select a specific compiler and CppCheck. Even though it takes me time to adjust to the IDE GUIs and how to adjust it's settings, I also noticed other IDEs for my Linux Mint to try out. I know how to use the Makefile as well selecting the compiler like gcc/g++ as well as using clang/clang++, but it would be easier to have the error logs to be printed not on the terminal as well looking directly where the error and warning are corresponded.

Which Linux IDE for C++ coding is best and more suitable for C++ learners? Besides I'm not a C++ pro. And I am NOT going to pay for those IDEs like Visual Studio Pro Edition nor CLion, as it seems foolish to pay for those.
