Trying to compile opencv on my Mac from source.
I have following CMakeCache.txt: http://pastebin.com/KqPHjBx0
I make ccmake .., press c, then g.
Than I make sudo make -j8:

Than I make sudo make install:

And than I make import cv in python and get "Segmentation faul" with this stacktrace:

I don't know what could be useful to help me, pls. ask, I'll get it.
回答1:
I had a same situation and resolved the following steps.
In ccmake(ccmake -G "Unix Makefiles" .), toggle to the advanced mode pressing t.
change PYTHON_LIBRARY value to /opt/local/lib/libpython2.6.dylib and PYTHON_INCLUDE_DIR to /opt/local/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6.
Note that the specific path depends, of course, what version of Python you are using (2.6 or 2.7 etc.). Also, if you are using the system Python, instead of MacPorts (which is in /opt), then you probably want PYTHON_LIBRARY to be /usr/lib/libpython2.6.dylib

From your logs, you seem to use MacPorts and python 2.6.
opencv will compile fine on this framework:
sudo port install opencv +python26
be sure to have py26-numpy installed to have support for basic functions such as cv.fromarray :
sudo port install py26-numpy
means that your problem has been solved by the MacPorts community. is it a problem of the latest source? the version you compile is the one (opencv 2.2.0) used by macports.
Your question is about compiling from source. Looking at the portfile linked to that you'll be able to locate your problem. to find the Portfile, do:
port file opencv
or directly
sudo port edit opencv
this will list all configuration flags necessary for a working openCV.

Typing:
sudo port select --set python python27
fixed the segfault for me.
回答4:
The problem is simple, macports did rewrote cv.so in ~/usr/lib
if you installed OPENCV using
sudo port install opencv +python26
type
sudo port select --set python python26
if you installed OPENCV using
sudo port install opencv +python27
type
sudo port select --set python python27
The "bug" is that python2.7 interpreter is trying to open python2.6 pre-compiled binary that gives seg fault 11 (or vice versa)
The nevereinding problem with opencv is that it does not have source code, just binaries that are stongly dependent on which compiler there were built on (which platform etc.)
