C++ compiler flags

[Andrei]

As far as I understand gcc 4.5.2 is used as a C++ compiler. But what are the compilation flags? Are they "-O3 -funroll-loops" as in the starter package makefile or somewhat else? Can I change the flags?
And if it's not possible specify arbitrary flags is there any way to enable fast math at least?

No, you can't change the compiler flags unfortunately. If you can prove a large popular demand, you may be able to convince the organizers to add a new "language" with different compiler options.

vanilla C++ uses -O3 -funroll-loops
C++11 uses -std=c++0x -O3 (no unroll loops)


Anyway, why do you care about fast math? There's not much use for floating point here anyway.

... does that mean that if I rename MyBot.cc to MyBot.cpp, I'll get C++0x or C++11 support and be able to use the fancy new STL containers and super-shiny lamdas?

Do I need to rename ALL my .cc files to .cpp? (No hardship.)

I am SO STOKED - this solves all my problems if it is true!

Actually you only need to name your main file MyBot.cpp, as the name of the main file is what's used to determine the language.

Remember, GCC 4.5 C++11 features only.

I'm using a 3rd party library (open source) for some part, and it uses
#include <LIBNAME/internal/somefile.h>
internally. This means that I should specify an -I compiler option to make this work.

However, I don't seem to have any option to do so at this time. Am I supposed to rewrite hundreds of #include statements to relative paths, or can we somehow provide hints to the compilation script?
Or can we maybe have a "language" that is MyBot.makefile or smth?

[Parasprites]

Unfortunately, there's no way to use include paths at the moment. So your only options are to rewrite the library inclusions or make do without. I really hope they fix this. At the very least, they could provide a preinstalled version of common libraries i.e. Boost.
