Does DevKitARM *officially* support C++? Or even if unofficially, how comepletely does it support it? I noticed that I can declare a class and instantiate it statically, but as far as I can tell, I can't instatiate anything dynamically with 'new', as I get teh error "undefined reference to `operator new(unsigned long)'" from the linker. Are there other C++-specific things DevKitARM doesn't totally support?

Compile/Link with arm-elf-g++ if you have a C++ application. new and delete should work then.

I'm having the same problem and I _do_ compile with arm-elf-g++

Should it not be arm-agb-elf-g++ ?
Do you need to link newlib?

It's a bit long since I last did something in gba development. But as far as I remember compiling with arm-elf-g++ worked.
I'll check that out when I'm at home.

I'm pretty sure it was arm-elf-g++

Maybe, but I always thought that compiling with g++ does this automatic. Thats why I compile my C++ aplications with g++ instead of gcc

arm-agb-elf-g++ was DevKit Advance, which hasn't been updated in a long time.
arm-elf-g++ is devkitARM, which is still considered maintained.

I tried it now and it works fine. Make sure to use arm-elf-g++ for linking to.

I just got that working too.
BTW, I noticed that in my test program, using g++ added 46kbyte to the ROM size. Does anyone know if this is constant for any DevKitARM project going from gcc to g++, or can this size increase vary from project to project?
