What's the latest version of OpenCV that will work? opencv.so: undefined symbol: cvReleaseHist in Unknown on line 0

PHP Warning: PHP Startup: Unable to load dynamic library '/home/web/opencvphp/OpenCV-for-PHP/modules/opencv.so' - /home/web/opencvphp/OpenCV-for-PHP/modules/opencv.so: undefined symbol: cvReleaseHist in Unknown on line 0

running Ubuntu 14.04 x64

sudo apt-get install python-software-properties software-properties-common
(ppa for ffmpeg)
sudo apt-add-repository ppa:mc3man/trusty-media
sudo apt-get update

at this point I installed opencv-2.4.10 using the following method because sudo apt-get install opencv was not working, and I found no ppa that I could add that would make it work
also the below script did not run without issues, so I just ran the lines one at a time so I fould fix issues as I went, like the unzip package not being installed, etc:
https://help.ubuntu.com/community/OpenCV

git clone https://github.com/mgdm/OpenCV-for-PHP.git
cd OpenCV-for-PHP
phpize
./configure && make
make test (this is where I have the error)

sudo make install (not ran this line yet)

opencv-2.4.10
PHP_VERSION : 5.5.9-1ubuntu4.5
ZEND_VERSION: 2.5.0

$ make test

Build complete.
Don't forget to run 'make test'.

Feature Request Capture::release

Hello

if I use the use OpenCV\Capture::createCameraCapture(0); on a webserver the, the process did't close the access to /dev/video if it is finished.
So a second call ist not possible in that case the device is busy,
On the CLI the files are all closed.

The OpenCV release function maybe help.

Error during make test of opencv.so

I've managed to install it once, on our internal test server.
But for some reason I can't get it to install on our production server. I have no idea why. It compiles without error, but make test throws the following error:

/usr/bin/php: symbol lookup error: /usr/src/Builds/OpenCV-for-PHP/modules/opencv.so: undefined symbol: cvSetErrMode

Any ideas what might cause this?

when in run

use OpenCV\Image as Image;
/* Load the sample image */
$i = Image::load("test.jpg", Image::LOAD_IMAGE_COLOR);
$rgb = $i->convertColor(Image::RGB2GRAY);

i got this error

with Image::BGR2Luv,Image::BGR2HSV,Image::RGB2HSV,Image::RGB2YCrCb there is no error

I could load the image directly in gray with
$i = Image::load("test.jpg", Image::LOAD_IMAGE_GRAYSCALE);

but with Image::load("test.jpg", Image::LOAD_IMAGE_ANYDEPTH);
i got Fatal error: Undefined class constant 'LOAD_IMAGE_ANYDEPTH' :
