c++ - Cross compiling Direct3D on Linux with mingw -

how configure mingw32 cross-compile direct3d apps windows? there possibility? have succeeded compiling code tutorial: http://www.directxtutorial.com/tutorial9/b-direct3dbasics/dx9b4.aspx - using code::blocks on kubuntu i586-mingw32msvc-g++. needed add #define unicode , remove #pragma ... parts this, , used header files /usr/i586-mingw32msvc/include , libs mingw package.

however cannot compile code tutorial: http://www.directxtutorial.com/tutorial9/b-direct3dbasics/dx9b5.aspx

mingw doesn't have d3dx9.h file. i've installed wine1.2-dev package wine versions of windows-related header files, have errors:

with #define unicode:

do have install through wine ms directx sdk? change code? i'm directx- , windows-related things noob want cross-compile simple examples of d3d , check if works.

ok! i've succeeded!

unfortunately, needed download microsoft directx sdk (april 2007) (i couldn't install newer ones wine).

then had install mingw using wine , install mingw-utils 0.3 (i had obtain reimp.exe file).

then set path in wine's register c:\windows;c:\windows\system;c:\mingw\bin

then made wine reimp.exe "c:\program files\microsoft directx sdk (april 2007)/lib/x86/d3dx9.lib". command generated d3dx9_33.a file, i've changed d3dx9.a , put in /usr/i586-mingw32msvc/lib/.

i have copied lacking header files directx sdk /usr/i586-mingw32msvc/include.

and then... compiled program, linking libd3d9.a , libd3dx9.a, , compiled, linked, , works!

so news is: 1 can compile windows directx programs under linux using linux version of mingw.

the bad news: 1 need install few mingw utilities , whole ms dx sdk using wine.

edit

and 1 more thing: needed make wchar*-related castings manually - mingw shouts errors if isn't done. goz helpful here.
