python - 使用 py2exe 构建带有扩展的 python 程序

Question

我很难找到 py2exe 配方，尤其是对于需要 c 扩展的情况。

以下配方在没有“ext_modules”部分的情况下也能正常工作。有了它，我得到“NameError: name 'Extension' is not defined.

from distutils.core import setup
import py2exe
import matplotlib
import os

s = os.popen('svnversion')
version = s.read()
f = open('cpa_version.py', 'w')
f.write('VERSION = "%s"\n'%(version.strip()))
f.close()

setup(console=['cpa.py'],
      options={
        'py2exe': {
            'packages' : ['matplotlib', 'pytz', 'MySQLdb', 'pysqlite2'],
            'includes' : ['PILfix', 'version'],
            "excludes" : ['_gtkagg', '_tkagg',
                          "Tkconstants","Tkinter","tcl"],
            "dll_excludes": ['libgdk-win32-2.0-0.dll',
                             'libgobject-2.0-0.dll', 
                             'libgdk_pixbuf-2.0-0.dll',
                             'tcl84.dll', 'tk84.dll']
            }
        },
      data_files=matplotlib.get_py2exe_datafiles(),
      # how to build _classifier.c???
      ext_modules = [Extension('_classifier',
                               sources = ['_classifier.c'],
                               include_dirs=[numpy.get_include()],
                               libraries = ['sqlite3'])]
)

_classifier.c 包括以下内容

#include "sqlite3.h"
#include "Python.h"
#include "numpy/arrayobject.h"
#include <stdio.h>

如有任何帮助，我们将不胜感激。

在修复了因忘记导入扩展而造成的小错误后，我遇到了其他错误，说明 -lsqlite3 标志存在问题。原来我需要按照此处列出的步骤操作:http://cboard.cprogramming.com/cplusplus-programming/82135-sqlite-questions.html

1. 从 sqlite.org/download.html 下载 sqlitedll-3_3_7.zip 和 sqlite-source-3_3_7.zip

2. 解压 sqlitedll-3.3.7.zip 然后从命令行运行:

   dlltool -D sqlite3.dll -d sqlite3.def -l libsqlite3dll.a

3. 将 libsqlite3dll.a(刚创建的)放在 MinGW lib 目录中。
4. 将 sqlite3.dll 放在您的系统路径中(c:\Windows\System32\对我有用)
5. 提取 sqlite-source-3_3_7.zip 并将 sqlite3.h 放入您的 MinGW 包含目录。
6. 链接时，您需要提供参数:-lsqlite3dll(这意味着将 libraries=['sqlite3'] 更改为 libraries=['sqlite3dll'])

...之后构建成功。

这里又是安装文件:

from distutils.core import setup, Extension
import py2exe
import matplotlib
import os
import numpy

setup(console=['cpa.py'],
      options={
        'py2exe': {
            'packages' : ['matplotlib', 'pytz', 'MySQLdb', 'pysqlite2'],
            'includes' : ['PILfix', 'version'],
            "excludes" : ['_gtkagg', '_tkagg',
                          "Tkconstants","Tkinter","tcl"],
            "dll_excludes": ['libgdk-win32-2.0-0.dll',
                             'libgobject-2.0-0.dll', 
                             'libgdk_pixbuf-2.0-0.dll',
                             'tcl84.dll', 'tk84.dll']
            }
        },
      data_files=matplotlib.get_py2exe_datafiles(),
      ext_modules = [Extension('_classifier',
                               sources = ['_classifier.c'],
                               include_dirs=[numpy.get_include()],
                               libraries = ['sqlite3dll'])]
)
