How to compile this extension? #1

Open benpptung opened 13 years ago

benpptung commented 13 years ago

Hi..thank you for this great extension. I'm trying to compile it, but failed.

I am using the following command :

phpize && ./configure && make && make install

and till end I got the following error message. ..... /usr/home/benpptung/OpenCV-for-PHP/opencv_image.c: In function 'zim_OpenCV_Image_haarDetectObjects': /usr/home/benpptung/OpenCV-for-PHP/opencv_image.c:766: error: too few arguments to function 'cvHaarDetectObjects'

I am using FreeBSD 8.2, and the OpenCV is 2.3.1, PHP is 5.3.8. Is there any document how to install the php extension? Any help would be appreciated.

mgdm commented 13 years ago

Hi, It looks like OpenCV 2.3 has changed the arguments to some of the functions. I'll see about getting it updated to handle that, and let you know.

Cheers Michael

benpptung commented 13 years ago

Hi...thank you for reply. I've tried to fix cvHaarDetectObjects parameter, but it seems there is not only this function, but also other function or constants, so I gave up eventually... ( ^_^" I am new to C), sorry cannot help.

antonvedeshin commented 13 years ago

Faced up with the same problem. I have just commented out this function, one function definition and one constant definition. Should work.

antonvedeshin commented 13 years ago

Michael, could you please fix this issue? Unfortunately I am not so familiar with open cv. Or at least please write down what and where approximately to fix, and we will fix it. Thank you in advance!

mgdm commented 13 years ago

I'll have a look when I get a spare minute - I want it to work with all the versions out there, so I'll need to do some version detection.

I have PHP 5.4.6 and OpenCv 2.4.1

Can you help??

mgdm commented 11 years ago

I've not tested it on PHP 5.4 yet. I'll try and fix that and let you know when it's done.

I get "duplicate symbol _opencv_original_error_handling in .libs/opencv_error.o and .libs/opencv.o for architecture x86_64 (macbook pro running mamp php 5.4.4.)

mgdm commented 11 years ago

I'll have a look at that tomorrow - I think I need to land the branch I've been working on. Thanks for the report!

Cheers, Michael

Hello hello...

I descovery the problem with the extension's installation using PHP 5.4 or 5.5.

edit the file opencv.c

and delete the lines 41, 42, 43, 44, 45 and 46.

ENJOY

Hi, i am getting following error,

Fatal error: Call to undefined function dl() in C:\xampp\htdocs\OpenCV\opencv.php on line 5

I am using PHP 5.4.7

ekoneko commented 10 years ago

Hello, I'm getting some errors when "make", like this:

    error: too few arguments to function call, expected 3, have 2
    php_opencv_make_image_zval(temp, return_value);

I find the function in "php_opencv.h":

    PHP_OPENCV_API zval *php_opencv_make_image_zval(IplImage *image, zval *image_zval TSRMLS_DC);

It's just two arguments?

I sovled it... replace

    php_opencv_make_image_zval(temp, return_value)

to 

    php_opencv_make_image_zval(temp, return_value TSRMLS_CC)

But I got another problem about version of libopencv :(

mgdm commented 10 years ago

I've not really had any time to work on this extension recently. I'm hoping to do so in the next couple of weeks so hopefully it'll work on recent OpenCV and PHP distributions.

gr0g commented 10 years ago

@mgdm nice work on the extension - how about you tell us more what's the list of things you'd like to be fixed/changed/improved so we can contribute. Thanks!

Hello. When I do "make test", I have a warning

PHP Warning:  PHP Startup: Unable to load dynamic library '/home/kolya/www/disney.cinderella/opencv/modules/opencv.so' - /home/kolya/www/disney.cinderella/opencv/modules/opencv.so: undefined symbol: cvRelease in Unknown on line 0

_004 Can you help me? Before me is a challenge to compare the two images. Perhaps you know still some way how to do it, if you can not correct extension.

fernandohu commented 9 years ago

Hey, if you want to use OpenCV, just use C++, Ruby or Java. Actually, there is no port of OpenCV to PHP.

Unfortunately I do not know these languages. Perhaps you know a way how to learn steper similarity of two images? I have a sticker and I need to find out whether he has to download photos.

fernandohu commented 9 years ago

I don't think I am the best person to give you tips of computer vision. Nevertheless, I didn't understand what you want to do. Can you give more details?

prokopov-nikolai commented 9 years ago

The file is an example of what needs to be done. https://yadi.sk/i/meOLgTFoe2n7L

fernandohu commented 9 years ago

I don't know if it helps, but you can try this page: http://www.intorobotics.com/how-to-detect-and-track-object-with-opencv/

It shows various ways of doing object recognition with OpenCV. Good luck with that, it is not a trivial task to do. And, if you are going the OpenCV way (it seems there is no other option), I recommend you forgetting PHP. No one has made a decent port to it (it is a so big library).

Dears,

I discovered a bug when to OpenCV 3.0.0....

Error: /home/wellton/Downloads/OpenCV-for-PHP-master/opencv_image.cpp:718:32: error: in C++98 'colour' must be initialized by constructor, not by '{...}' CvScalar colour = { 255, 0, 0 };

Solution: Open /home/wellton/Downloads/OpenCV-for-PHP-master/opencv_image.cpp Go to line 718. Change: CvScalar colour = { 255, 0, 0 }; TO: CvScalar colour = CvScalar();

=)

ENJOY... in the my fork is work.
