OpenCV 的 Python - OS X

Question

在 OS X 10.5 (intel) 上构建 OpenCV 时出现以下错误：

ld: warning in .libs/_cv_la-_cv.o, file is not of required architecture
ld: warning in .libs/_cv_la-error.o, file is not of required architecture
ld: warning in .libs/_cv_la-pyhelpers.o, file is not of required architecture

make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

运行 ./configure --without-python 时一切正常。另一个奇怪的是，当我使用 Python 2.4.5 或 2.5.1 时一切正常，切换到 Python Framework 2.5.2 后出现问题

Answer 1

在链接时寻找 /Developer/SDKs/MacOSX10.4u.sdk 时，它会警告不同的架构，这似乎有点奇怪 - 你能否给我们一些关于你的构建环境的更多细节（XCode、GCC、Python 的版本, $PATH 等）

或者，任何可用的 OpenCV 二进制文件都不适合您吗？

Answer 2

/Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib 只是到 /usr/local/lib 的链接 删除导致我收到警告的文件后：

ld: warning in .libs/_cv_la-_cv.o, file is not of required architecture
ld: warning in .libs/_cv_la-error.o, file is not of required architecture
ld: warning in .libs/_cv_la-pyhelpers.o, file is not of required architecture
ld: warning in .libs/_cv_la-cvshadow.o, file is not of required architecture
ld: warning in ../../../cv/src/.libs/libcv.dylib, file is not of required architecture
ld: warning in /Users/Pietras/opencv/cxcore/src/.libs/libcxcore.dylib, file is not of required architecture
Undefined symbols for architecture i386: ... `

这些文件是由make创建的。

gcc: i686-apple-darwin9-gcc-4.0.1

$路径：

/Library/Frameworks/Python.framework/Versions/Current/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:/sw/bin:/sw/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/AVRMacPack/bin:/usr/X11R6/bin

XCode 3（最新）

Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04) - 来自 python.org 的 MacPython （试图降级并使用它而不是 2.5.2，但这不再起作用了......）

which python
/Library/Frameworks/Python.framework/Versions/Current/bin/python

我没有找到任何适用于 OS X 的 Python OpenCV 二进制文件。 我尝试将 macports 中的 python2.4 或 2.5 设置为默认值并进行编译和安装，但是当我尝试导入时，出现总线错误或致命 Python 错误解释器未初始化（版本不匹配？） 然后它就退出了。

Answer 3

好的，我已经解决了

它需要使用来自 macports 或其他的 python 编译。然后我需要运行/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python2.5（这是我以前的python 版本），OpenCV 就可以工作了。
