GCC errors - please help!

Hey everyone, I just downloaded a GBA emulater and compiler. The compiler includes the GCC compiler. I never used this compiler before. I ran this simple program.. #include <iostream> class CLogStream; class cLogStream //: std::ostream { std::string m_strData; //errors?? public: cLogStream () {} ~cLogStream () {} }; int main() { return 0; } This code is from my original logging system, which works great in MSVC++. Anyways, GCC is giving me errors.. gcc -o zengine.elf main.cpp -lm ccdgJ7pr.o: In function `__static_initialization_and_destruction_0(int, int)': ccdgJ7pr.o(.text+0x54): undefined reference to `std::ios_base::Init::Init()' ccdgJ7pr.o(.text+0x7c): undefined reference to `std::ios_base::Init::~Init()' collect2: ld returned 1 exit status What could be the cause for this? My code works with MSVC++ 6. (Okay..The pluses aren showing..Its _cplusplus.) Thanks!

It was from DevKitAdv GBA compiler. I got it from
this site.

Heres a link to the exact *.zip I downloaded, incase anybody's
interested:

@ender7771: iostream is part of the C++ standard, so
almost all compilers should support it.

Yes, but for certain targets (where storage of the library would be hard/impossible - e.g. embedded platforms - e.g. possibly the GBA) certain parts of the SC++L (including iostreams? not sure...) can be excluded while still being considered complaint with the C++ spec.

It sucks, but it's possible... even assuming a perfect world where everyone implements the latest version of the C++ spec to the line :-). (I think, anyways, iostreams might be on the required list... I don't have a copy of the standard handy)

In a freestanding environment, a conforming C++ compiler implementation is only required to provide <cstddef>, <limits>, <cstdlib>, <new>, <typeinfo>, <exception>, <cstdarg>.

<cstdlib> needs to at least contain abort(), atexit() and exit().
