Question

我的环境是：

Windows 7。 PyDev IDE（eclipse）。 Python 2.7。

我想编译和测试一些我用C ++编写的代码（将来，这段代码将由Python脚本生成）。我需要编译一个简单的.c文件，用作python扩展。

现在我的代码是：

/*
file: test.c 
This is a test file for add operations.
 */
float my_add(float a, float b)
{
    float res;
    res = a + b;
    return res;
}

.py文件：

import subprocess as sp
import os
class PyCompiler():
    def __init__(self, name):
        self.file = name
        self.init_command = r"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat"
        self.compiler_command = r"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\cl.exe"
        sp.call(self.init_command + " " + self.file)

    def compile(self):
        alfa = sp.call(self.compiler_command)
        print(alfa)

TestCode = PyCompiler(r"C:\Python27\CodeGenerator\src\nested\test.c")
TestCode.compile()

如果我启动此脚本，我会得到：

output

这意味着我在方法PyCompiler.compile中出错，因为subprocess.call的返回不是1.

您能就此问题提供一些指导吗？

你知道其他任何做法吗？

我实际上设法通过安装MinGW并使用它来编译我的C代码来解决问题。我的python代码是：

import subprocess as sp
import os
import importlib

my_env = os.environ

班级初学者：

class PyCompiler():
        def __init__(self, name_in, module, dep_list):
            self.file = name_in
            self.dep = dep_list
            self.module_name = module
            self.compiler_command = r"python setup.py  build_ext --inplace -c mingw32 "
            ''' Here it goes the creation of the setup.py file: '''
            self.set_setup()

和班级方法：

def compile(self):
    command = self.compiler_command
    self.console = sp.call(command, env=my_env)

def include(self):
    module = __import__(self.module_name)
    return module

def set_setup(self):
    dependencies = ""
    for elem in self.dep:
        dependencies = dependencies + ",'"+elem+".c'"
    filename = "setup.py"
    target = open (filename, 'w')
    line1 = "from distutils.core import setup, Extension"
    line2 = "\n"
    line3 = "module1 = Extension('"
    line4 = self.module_name
    line5 = "', sources = ['"+self.file+"'"+dependencies+"])\n"
    line6 = "setup (name = 'PackageName',"   
    line7 = "version = '1.0',"
    line8 = "description = 'This is the code generated package.',"
    line9 = "ext_modules = [module1])"
    target.write(line1 + line2 + line3 + line4 + line5 + line6 + line7 + line8 + line9)
    target.close()

执行代码：

TestCode = PyCompiler(file, module, [lib])
TestCode.compile()
test = TestCode.include()

file是要编译的C文件。
module是分配给创建的python模块的名称。
[lib]是aditional C依赖项的列表。

使用在windows shell下运行的Python解释器编译C ++代码
