如何在 OSX 10.5 32 位上安装 OpenCV 2.2 for ActivePython 2.7？

Question

标题就是整个问题。

• 我尝试过使用 --build32 选项进行自制程序
• 我尝试过 macports
• 我尝试过下载源文件并从头开始编译。

以上所有内容都安装完美，没有任何问题。然而，在从各种安装中找到正确的 cv.so 文件并将它们移动到我想要使用 OpenCV 的 Python 版本的正确 /site-packages/ 目录后，并确保它在 PYTHONPATH 中正确无误 - - 我总是收到此错误：

ActivePython 2.7.1.4 (ActiveState Software Inc.) based on
Python 2.7.1 (r271:86832, Feb  7 2011, 11:33:10) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>> import cv

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/cv.so, 2): no suitable image found.  Did find:
    /usr/local/lib/python2.7/site-packages/cv.so: mach-o, but wrong architecture

同样，这是在我竭尽全力寻找 32 位版本之后发生的。我搜索了 OpenCV 网站，找不到任何 2.2 版本的 32 位特定源文件的链接。当我在从头开始安装期间监视它时，我注意到它在配置、make 和编译期间正确传递了 arch i386 选项（因为它应该检测我的系统体系结构是 32 位）。

我真的很不知所措。有什么想法吗？请记住，我特别尝试让 OpenCV 2.2 版本专门与 Python 的 ActivePython 2.7 版本一起使用。我有 OpenCV 2.1 和 Python 2.6.6 一起使用，但我刚刚更新了我的工作计算机以在 Ubuntu 中使用 OpenCV 2.2 和 ActivePython 2.7，并且我希望能够在该计算机和我的家庭计算机之间顺利共享内容。对于我正在做的事情来说，拥有最新的 OpenCV 非常重要。

好的，我的具体步骤如下：

(1) 将 OpenCV 源代码提取到目录 ~/OpenCV-2.2.0/ (2) 运行cmake，使用gedit添加上面提到的体系结构字符串，然后运行sudo make，然后运行sudo make install。这是后两个步骤的输出：

为了确定，根据安装过程中找到的 Python 路径，我尝试了：

似乎无论我做什么，我都会遇到此架构错误。我已经直接安装了 OpenCV，没有任何问题，无论 CMakeCache.txt 中是否有此架构字符串说明符，两种方法都会导致相同的错误。

我很感谢您的帮助，还有其他想法吗？

Answer 1

我用 ActivePython 2.7 成功构建了 OpenCV 2.2。

要构建 32 位，您需要：

1. 将 CMAKE_OSX_ARCHITECTURES:STRING=i386 添加到 CMakeCache.txt（在运行 cmake 后立即）
2. 重新运行 cmake

如果您需要我遵循的完整构建说明，请告诉我......我将更新此答案。
