D语言配置 DirectX 环境

d语言 directx

此篇所言只针对windows 32 bit 版本 Linux/Unix/Mac/Win64 无关... Win32 下里面的那个makefile窝用了无法编译成功 .. 如果你可以编译成功的话可以无视这篇文章

1. 下载
首先需要在官网下载d语言的编译器 ... http://dlang.org/download.html

然后下载 d 语言的directx 库 - bindings 这个项目托管在 GitHub 了 ..https://github.com/CS-svnmirror/dsource-bindings

还有一个 omf 格式的 lib 工具这个工具在下载包里面貌似是没有的 http://pan.baidu.com/s/1dD1ul6T(d语言使用 omf 格式的lib与vc的 coff 格式 lib冲突)

所有原料工具准备完成之后开始配置环境 ..

2.配置
dmd编译器设置文本模式打开 dmd2\windows\bin 下的 sc.ini 在
; environment for both 32/64 bit
[Environment]
DFLAGS="-I%@P%\..\..\src\phobos" "-I%@P%\..\..\src\druntime\import" 后面加上 "-I%@P%\..\..\src" ( 示例 : DFLAGS="-I%@P%\..\..\src\phobos" "-I%@P%\..\..\src\druntime\import" "-I%@P%\..\..\src") 保存退出 ...

bindings 设置

把 bindings 下的 Win32 文件夹移动到 dmd 编译器文件夹的 dmd2\src 下 ... 好了剩下就是生成 lib 了实际上这也是本篇比较麻烦的地方窝只说怎么做没说为什么 .. 有兴趣可以自己看看函数调用约定以及c/c++/d 风格的函数修饰名以及 implib/.def/lib 的用法

lib 设置

打开 lib 包里面的 implib ... bindings 不提供 lib 不然自己要LoadLibaray 或者 GetProcAddress 了 ... 很麻烦 ...再把系统system32下的 d3d9.dll 拿出来新建一个.def文件写上 (其余函数/DLL一样)
LIBRARY "d3d9"

EXPORTS
_Direct3DCreate9@4 = Direct3DCreate9
保存退出打开命令行输入 implib /noi /system d3d9.lib d3d9.def 得到的lib 放在默认的lib目录下 ... (dmd2\windows\lib)

编译一下如下代码试一下是否配置成功

module winsamp;

pragma (lib, "gdi32.lib");
pragma (lib, "d3d9.lib");

				mov ESI, 48[ESP]    ; // ESI <- width
				mov EAX, 44[ESP]    ; // EAX <- color
		
				mov EBP, 40[ESP]	; // EBP <- pitch
				lea EBX, [ESI*4]    ; // EBX <- get correct x width size (32 bit * 4)
		 
				mov EDI, 36[ESP]    ; // EDI <- p32BitVram
				sub EBP, EBX        ; // EBP <- correct difference value
		
				mov EBX, 52[ESP]    ; // EBX <- y cnt 
				mov ECX, ESI        ; // save frame 
		
				align 16            ; // 
		
		FBG_loop:
   
				rep                 ; // pixel copy 
				stosd               ;
		
				add EDI, EBP        ; // move pixel pointer
				mov ECX, ESI        ; // recover x cnt 
		
				dec EBX             ; // dec y cnt
				jnz FBG_loop        ; // is end 
		
				popad               ; // over restore REG
