Compiling OpenSSL on windows
提问by zkarthik
Quoting the instructions for building OpenSSL:
引用构建 OpenSSL 的说明：
Then from the VC++ environment at a prompt do:
nmake -f ms\ntdll.mak
然后在提示下从 VC++ 环境中执行：
nmake -f ms\ntdll.mak
When I do this, I get
当我这样做时，我得到
cl /Fotmp32\cryptlib.obj -Iinc32 -Itmp32 /MT /Ox /O2 /Ob2 /W3 /WX /Gs0

such file or directory
NMAKE : fatal error U1077: '"c:\Program Files\Microsoft Visual Studio 9.0\VC\BIN
\cl.EXE"' : return code '0x2'
Stop.
Looks like I am missing setup of some environment variable that will point to where unistd.h. Not sure what it is though.
看起来我缺少一些环境变量的设置，这些变量将指向 unistd.h 的位置。不确定它是什么。

Copy C:\Program Files\Microsoft Visual Studio 9.0\VC\Include\io.hunder the name unistd.hin the same directory and retry the build.
在同一目录中C:\Program Files\Microsoft Visual Studio 9.0\VC\Include\io.h的名称下复制unistd.h并重试构建。

Look in the Common7/Tools subdirectory where Visual Studio is installed (for a typical installation C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools) for a batch file named vsvars32.bat. When you open a command prompt, run this batch file. It will define environment variables pointing to various installation directories, including where various standard header files are installed.
在安装 Visual Studio 的 Common7/Tools 子目录中查找名为 vsvars32.bat 的批处理文件（典型安装为 C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools）。当您打开命令提示符时，运行此批处理文件。它将定义指向各种安装目录的环境变量，包括安装各种标准头文件的位置。
