0. 概述
Lenix直接使用PE格式作为可执行文件的格式了，有侵犯那啥产权的嫌疑啊，不过嘛，现在没有商用，应该不算那啥，如果有机会商用，那时在想办法了，毕竟开发一个编译器比较困难，链接器就相对容易一点，毕竟我就写过，能用的，LENIX最初的版本就是用自己写的链接器制作的映像。
用VS2019来编译Lenix程序，可以在IDE里编译和链接，也可以用命令行的方式进行编译和链接。实质其实就是设置ml.exe和link.exe的参数，让编译器不要干太多额外的事情。
至于使用IDE来调试，那就不用想，LENIX是操作系统，经常使用要运行在RING0特权级的指令，在windows的调试器里直接就挂了。
LENIX是操作系统，在windows看来，就是个大病毒，如果打开杀毒程序，刚编译出来的文件就会被干掉。所以，最好是别开杀毒软件。
1. 设置编译参数
就是设置ML.EXE的参数
1.1 设置附加包含目录、禁用SDL检查
要包含头文件的目录和标准库的文件目录 include; include\c
这里我是使用了完整路径，具体的位置就看开发资源放哪里了。
在同一个设置窗口中，还有一个SDL检查，这个选项要关闭，否则VC会插入一些函数的调用，这个就属于我不想要的功能了，其实吧，是我不知道如何提供它需要的函数功能，所以，只能禁用。
1.2 忽略标准包含路径
其实这个不是必须的，但最好这么做，因为标准包含路径通常是开发正常的windows程序需要使用的，如果不忽略标准包含路径，有可能会包含进同名文件，比如标准C的头文件，会造成很多奇怪的问题。
如果忽略标准包含路径，就可以实现开发正常的windows程序和开发lenix互不影响。
1.3 禁用安全检查、禁用增强指令
安全检查是VC提供的一项额外功能，我也不知道该如何实现，干脆就禁用了，安全就由自己负责吧。
至于增强指令集，就是SSE、SSE2、AVX等等之类的，暂时还是不要用了，因为现在我还没办法在非法指令异常中实现指令模拟，真要碰上指令异常，就只能退出进程了。所以干脆别用，等升级版在完善吧。
2. 设置链接参数
设置LINE.EXE参数
2.1 设置附加库目录
具体的路径要看开发资源放在什么位置，我是使用了完整的路径
2.2 设置附加依赖项、忽略所有默认库
就是需要用到的目标文件（obj）和库文件（lib），
| 文件名 | 说明 |
|---|---|
| lenix.lib | 这是系统文件的输出库，提供了进程、内存、文件系统、设备管理、虚拟计算机模型、动态扩展模块管理等等功能的输出函数 |
| lnxc.lib | 标准C库，和一些lenix扩展。不过嘛，现在对于标准C库的支持还不足，只是完成大部分的文件功能 |
| libc.lib | 这个实际上是VC6时代的文件了，我从VC6里面找出来的。用这个主要是VC在编译64位的整数乘除时，用到里面一些函数，这些函数我还不会，也是在没时间取研究了，只能直接用现成的了 |
| msvcrt.lib | 这个和libc.lib一样的情况 |
至于忽略所有默认库，这是为了避免莫名其妙的使用了windows的库，防止库文件命名与windows的文件冲突
2.3 禁用固定基址
这个选项可以让Windows将程序装载到内存的任意位置。但是对于exe来说，一般都是固定基址（通常是0x00400000，也就是线性地址4M的位置），这样可以提高装载性能。
Lenix并没有使用MMU，因此也就没有为每个进程提供一个独立的地址空间，也就不能使用固定基址了。禁用了固定基址后，链接的时候，就会生成重定位节，LENIX就可以使用这个重定位节来装载程序了。
2.3 禁用具有安全异常处理程序
这个选项也会让VC生成我不知道该如何提供对应功能的代码，只能禁用了。
3. 同一段代码编译后的对比
就一段简单的代码

其实吧，你以为就一个简单的程序？后边的支撑吓到你没有？
4. 命令行编译
这里就可以看VC给出的命令行了， 先看编译的参数，长长的一段，
/X /permissive- /GS- /GL /analyze- /W3 /Gy /Zc:wchar_t /I"D:\OrderSourceStudio\Lenix\Lenix\include"
/I"D:\OrderSourceStudio\Lenix\Lenix\include\c" /Zi /Gm- /O2 /sdl- /Fd"Release\vc142.pdb"
/Zc:inline /fp:precise /D "NDEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE"
/errorReport:prompt /WX- /Zc:forScope /arch:IA32 /Gd /Oy- /Oi /MD /FC /Fa"Release\" /EHsc
/nologo /Fo"Release\" /Fp"Release\lnxdbg.pch" /diagnostics:column 5. 命令行链接
这链接参数，怎么样，这么长一段，看着都烦躁
/OUT:"D:\OrderSourceStudio\Project\lnxdbg\Release\lnxdbg.exe" /MANIFEST /LTCG:incremental
/NXCOMPAT /PDB:"D:\OrderSourceStudio\Project\lnxdbg\Release\lnxdbg.pdb" /DYNAMICBASE

/SUBSYSTEM:CONSOLE /MANIFESTUAC:"level='asInvoker' uiAccess='false'"
/ManifestFile:"Release\lnxdbg.exe.intermediate.manifest" /MAP /OPT:ICF /ERRORREPORT:PROMPT
/NOLOGO /LIBPATH:"D:\OrderSourceStudio\Project\LENIX\Release"
/LIBPATH:"D:\OrderSourceStudio\Lenix\Lenix\lib\c"
/LIBPATH:"D:\OrderSourceStudio\Lenix\Lenix\lib\vc" /NODEFAULTLIB /TLBID:1 6. 使用NMAKE编译
其实VC也提供了make程序，只是它的名称是nmake。因此VC也可以用makefile来编译，挺好用的，不过嘛，在windows下编程，估计很少人会用到这个东西。
