OpenCV not compiling #18590

I am trying to compile OpenCV with the latest version of XCode, Mountain Lion and Homebrew.

I seem to be getting an error in the compilation process.

I am attaching all the logs in this gist

If your'e using Java 1.7, this won't compile.

Subho Banerjee

I changed the JAVA_HOME variable like so

export JAVA_HOME=`/usr/libexec/java_home -v 1.6`

But now I am stuck with another error in the compilation. It seems to be getting stuck compiling the Python bindings --

Subho Banerjee

I think I have found what seems to be causing this -

I downloaded OpenCV's latest release (v2.4.4), which homebrew is trying to install; and I tried to compile it myself. The CMake is not able to find libpython.dylib. It is trying to use the system default --

-- Found PythonInterp: /usr/local/bin/python2 (found suitable version "2.7.3", minimum required is "2.0")
-- Could NOT find PythonLibs: Found unsuitable version "2.7.2", but required is exact version "2.7.3" (found /usr/lib/libpython2.7.dylib)

I am using python package available on homebrew. Doesn't this library come along with the python package?

Samuel John

That two lines show two different python versions. 2.7.3 (probably the brewed python) and 2.7.2, which is probably from OS X.

If you build OpenCV yourself, you should call ccmake . in the source dir and set-up the python and python lib in that terminal gui. You might need to press c and t or something to first "configure" in cmake and then go to advanced options. I can't remember that correctly.

Samuel John

I reproduced you initial error

    [javac] /private/tmp/opencv-wJ9Z/opencv-2.4.4/macbuild/src/org/opencv/core/Core.java:474: error: unmappable character for encoding ASCII

I can fix that by removing the line env :std from the formula. Do you want to test that locally and report back?
I am not sure if you need javac bindings and if they are disabled with "superenv" (the build environment homebrew uses if env :std is not present.

Samuel John

Also I found that the OpenCV Formula would need some love in terms of what features and libs it needs during build. Homebrew has almost all of them. If no one volunteers, I could put that on my todo list ..

Subho Banerjee

@samueljohn I have python 2.7.3 installed from brew. But I cant find the corresponging libpython.dylib file either in /usr/local/lib or in Cellar folder.

I will try the build removing the env :std

Subho Banerjee

Its working now. But I still have to set the JDK version to 1.6

Samuel John

python-config --libs and python-config --ldflags might help...

Samuel John samueljohn was assigned
Subho Banerjee

This is what I get --

~|⇒ python-config --libs
-ldl -framework CoreFoundation -lpython2.7

~|⇒ python-config --ldflags
-L/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config -ldl -framework CoreFoundation -lpython2.7 -u _PyMac_Error Python.framework/Versions/2.7/Python

I guess the problem is that I dont have a libpython.dylib anywhere in this path

~|⇒ tree /usr/local/Cellar/python/2.7.3/ | grep libpython.dylib
~|⇒
Samuel John

I have Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib.

Subho Banerjee

I have that file as well. However, OpenCV is not able to find it using cmake.
Here is the relevant portion of the cmake output

-- Found PythonInterp: /usr/local/bin/python2 (found suitable version "2.7.3", minimum required is "2.0")
-- Could NOT find PythonLibs: Found unsuitable version "2.7.2", but required is exact version "2.7.3" (found /usr/lib/libpython2.7.dylib)

And this is the summary

--   Python:
--     Interpreter:                 /usr/local/bin/python2 (ver 2.7.3)
--     Libraries:                   /usr/lib/libpython2.7.dylib (ver 2.7.2)
--     numpy:                       /Library/Python/2.7/site-packages/numpy-1.8.0.dev_bbcfcf6_20130307-py2.7-macosx-10.8-intel.egg/numpy/core/include (ver 1.8.0.dev-bbcfcf6)
--     packages path:               lib/python2.7/site-packages
Samuel John

I will double check and take care of that. Also the numpy it found is from system python. Big fuck-up ahead.

Samuel John

I guess we have to do the same ugly hacks as for vtk.

Samuel John

maybe the numpy is not from system python, but it's definitely not in /usr/local/lib/python2.7/site-packages where it would en up being installed for the brewed python.

Subho Banerjee

I am using the numpy version that comes from the homebrew-python tap.
https://github.com/samueljohn/homebrew-python/blob/master/numpy.rb

Will that make a difference?

Samuel John

That's my tap :-)
But with a brewed python, it should end up in /usr/local/lib/python2.7/site-packages/numpy.
Strange. Do you have a distribute or setuptools in /Library/Python/2.7/site-packages that takes precedence over the homebrew provided ones?

Subho Banerjee

Not that I know. Is there some way I can check. In terms of my $PATH and $PYTHONPATH... they all point to the brewed version of python

Samuel John

Look inside /Library/Python/2.7/site-packages. What is there?

Subho Banerjee

I do have a lot of files in there -

@subszero remove pip-1.1-py2.7.egg/ from /Library/Python/2.7 and then reinstall the stuff in that dir. Then assure your pip installs new stuff into /usr/local/lib/python2.7/site-packages. Also your pip seems outdated.
You have several packages in both dirs.

Subho Banerjee

I uninstalled all those packages and reinstalled them into the /usr/local... brewed python.
Now, OpenCV picks up another version of numpy I have installed in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

Checking the dates on these, they were installed with easy_install from over a year ago. Will it be safe to just rm some of these files?

Samuel John

A newer version of Pip than you have is installed by homebrew into /usr/local/bin/pip. (You can safely brew rm python && brew install python if you have a very old python. Your packages in won't be deleted. But you may run into trouble if you have a pip in /usr/local/share/python and/or in the site-packages.)

Subho Banerjee

No I meant can I just delete the files (numpy and numpy-1.6.1-py2.7.egg-info as well as some of the others? Could they have come from easy_install?) from /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

They contain some numpy version that I do not remember installing!

Samuel John

No, don't ever delete anything from /System - there is Stuff OS X needs.
Do delete from /Library/Python/2.7/site-packages because all python's (2.7) import from there, too. So if you (accidently installed stuff with the system python, it may be incompatible with brewed python).
If you brew tap samueljohn/python && brew install numpy the numpy should end up in /usr/local/lib/python2.7/site-packages and not somewhere else. But the fact you have stuff in /Library is an indicator that somehow your pip/distribute is not set up correctly to install for the brewed python.

Subho Banerjee

The version of numpy from the tap is ending up there in the brew folder.
The version in the /System... folder is something I used to use a long time ago.
My $PYTHONPATH is set to the brew folder like so -

dotfiles|master ⇒ echo $PYTHONPATH
/usr/local/lib/python2.7/site-packages:

Then why is OpenCV picking up numpy from the /System... folder?
Now that I have this conflict of numpy being installed in both locations... how do I get rid of the /System... one?

I did install pip for system python once... But that was a long time ago.

Yeah that has proven to mess up any other python installation :-)
It's not your fault, though.

  1. Add /usr/local/share/python in front of your PATH.
  2. rm -rf /usr/local/lib/python2.7/site-packages/distribute-0.6.28-py2.7.egg
  3. rm -rf /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/distribute-0.6.28-py2.7.egg
  4. brew rm python
  5. brew install python

So if that does not work, then we have to try harder and I suggest to completely wipe out (or backup somewhere) the contents of /Library/Python/2.7/site-packages and reinstall the stuff you got there with pip install <stuff>.
If your brew install python it will install the up-to-date distribute and pip, so it might be good to remove anything with "distribute" or "pip" or "setuptools" in it's name before reinstalling python. Just go ahead and delete them.
