First and foremost, hello to all of you. I've been visiting here for quite some time trying to figure out various compiler errors in my journey to program in directX and I've seen no less than kind people and amazing coders. After buying the book "Beginning Game Programming", and reading threw the first few chapters, I became rather excited with the idea of creating a simple 3d world and there fore decided to Make that my senior project goal. I was able to get threw the book without a hitch up until chapter 6, when the directx header file d3dx9.h come into play. After trying to include that file I have encountered nothing but compiler errors and linker errors. Here is where I would greatly appreciate some help.

After fixing the linker errors and missing header files, as well as downloading the latest direct x SDK I have gotten down to these few errors.
In file included from C:/Dev-Cpp/include/d3dx9math.h:1787,
                 from C:/Dev-Cpp/include/d3dx9.h:47,
                 from ../Documents and Settings/Wil/Desktop/game/winmain.cpp:8:
C:/Dev-Cpp/include/d3dx9math.inl: In static member function `static void* _D3DXMATRIXA16::operator new(size_t)':
C:/Dev-Cpp/include/d3dx9math.inl:993: warning: `operator new' must not return NULL unless it is declared `throw()' (or -fcheck-new is in effect)

C:/Dev-Cpp/include/d3dx9math.inl: In static member function `static void* _D3DXMATRIXA16::operator new [](size_t)':
C:/Dev-Cpp/include/d3dx9math.inl:1008: warning: `operator new' must not return NULL unless it is declared `throw()' (or -fcheck-new is in effect)
To put it simply, I have no idea how to fix this error. I have not messed with d3dx9math.h or have the slightest clue of where it might be. If you have any ideas or solutions to this problem I would greatly appreciate any help. A few little extra details that may help with identifying my errors: IDE: Bloodshed Dev-C++ 4.9.9.2 Direct x SDK: Updated Dec 2006 OS: Windows XP Pro previous errors I had were fixed by installing all of the direct x header files and linker files into the dev-c++ base directories and by linking gdi32, d3d9, and d3dx9. I also threw in #pragma comment(lib, "libd3d9.a") in order to fix several errors as you can see in the code i pasted above. Thanks again, ~Poent [Edited by - Poent on February 1, 2007 11:31:34 PM]

First I havent seen the libd3d9.a, library, I don't know why youre using this way of declaring headers either, maybe if you do it the standard way (going into options->linker, and specifying all the needed libs there instead of using pragma, and try using the regular #include "d3d9x.h" and #include "d3d9.h". Try using the regular declaration/ library include ways and if it compiles fine, change it if you need. I personally prefer declaring the libs from within the options, but thats a choice of preference.
