Having problems building OpenCV 2.0 on CentOS 5? - opencv

Question

I'd been trying to install OpenCV library to my centos system however when i type make and hit enter after configuring with cmake, i get the following error:
[100%] Building CXX object tests/cv/CMakeFiles/cvtest.dir/src/amoments.o
[100%] Building CXX object tests/cv/CMakeFiles/cvtest.dir/src/affine3d_estimator.o

[100%] Built target cvtest
make: *** [all] Error 2
and interesting, once i got this error:
[ 99%] Built target mltest
[ 99%] Generating generated0.i
Traceback (most recent call last):
File "/home/proje/OpenCV-2.1.0/interfaces/python/gen.py", line 43, in ?
if True in has_init and not all(has_init[has_init.index(True):]):
NameError: name 'all' is not defined
make[2]: *** [interfaces/python/generated0.i] Error 1
make[1]: *** [interfaces/python/CMakeFiles/cvpy.dir/all] Error 2
make: *** [all] Error 2
What possibly is the cause of these errors? I need to install opencv immediately on this computer.

Answer 1

I had this problem.. It's the Python Interface...
By Default, Python 2.4 is installed on CentOS, and ot's not easy to upgrade to >2.6.
When OpenCV builds, it is confused by the Python version...
So I've disable the Python interface on "cmake" and it was OK.
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=NO ..
But, of course you can not use OpenCV with Python anymore.

The Python function all() was introduced with version 2.5. You are probably compiling with a version where all() does not exist in the Python language yet.
According to the Python Built-in Functions List, all() is equivalent to:
def all(iterable):
for element in iterable:
if not element:
return False
return True
You may also need to define any(). It is the equivalent of:
def any(iterable):
for element in iterable:
if element:
return True
return False
More than likely though, if the setup script requires Python 2.5, so will the rest of the Python wrapper.
