如何使用cython编译扩展？ [英] How can I compile an extension using cython?

问题描述

我想从示例页面这里编译一个简单的cython扩展在我的Windows 7 64位机器上安装了Python 2.6 64位版本。我从 Gohlke的页面为Windows 64位版本安装了Cython 0.15.1 。

I am trying to compile a simple cython extension from the example page here on my Windows 7 64-bit machine with Python 2.6 64-bit version installed. I installed Cython 0.15.1 for Windows 64-bit version from Gohlke's page.

基本上，此处和此处不是我的选择，因为我真的做需要Python 64位版本寻址更大的内存。此外，因为我正在尝试使用 Microsoft SDK for .NET 4 < a>，我不能在后面的解决方案中使用这种方法。

Basically, the answer from here and here are not my options because I really do need Python 64-bit version to address larger memory. Also, because I am trying to compile using Microsoft SDK for .NET 4, I cannot use the approach in the latter solution.

我尝试了步骤这里，并观察绿色窗口，但编译现在抛出无法找到vcvarsall.bat 错误。以下是我尝试的命令序列：

I tried the steps here and observed the green window but compilation now throws the cannot find vcvarsall.bat error. Following is the sequence of commands I tried:

C:\>cd "Program Files\Microsoft SDKs\Windows\v7.1\"
C:\Program Files\Microsoft SDKs\Windows\v7.1>set DISTUTILS_USE_SDK=1
C:\Program Files\Microsoft SDKs\Windows\v7.1>setenv /x64 /release

Setting SDK environment relative to C:\Program Files\Microsoft SDKs\Windows\v7.1\.
Targeting Windows 7 x64 Release

C:\Program Files\Microsoft SDKs\Windows\v7.1>e:

E:\>cd cython

E:\cython>python setup.py build_ext --inplace
running build_ext
skipping 'fib.c' Cython extension (up-to-date)
building 'fib' extension
error: Unable to find vcvarsall.bat

Any suggestions on how I solve this?

推荐答案

这是我的批处理文件的摘录：

Here is an excerpt from one of my batch files:

rem Configure the environment for 64-bit builds.
rem Use "vcvars32.bat" for a 32-bit build.
"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars64.bat"
rem Convince setup.py to use the SDK tools.
set MSSdk=1
set DISTUTILS_USE_SDK=1 

<实际上是VS2010，但Python 2.6是用VS2008编译的。如果你可以使用7.0 SDK（我认为它也被称为.NET 3.5 SDK），你将有权访问VS2008的编译器。混合不同的编译器和运行时库是很危险的。

The 7.1 SDK uses what is effectively VS2010 but Python 2.6 is compiled with VS2008. If you can use the 7.0 SDK (I think it is also known as the .NET 3.5 SDK), you will have access to VS2008's compiler. It is risky to mix different compilers and runtimes libraries.
