unable to install in Docker / php:8.0

[terrafrost]

I tried installing this with the following Dockerfile without success:

FROM php:8.0

RUN apt update && apt install -y wget
RUN wget https://raw.githubusercontent.com/php-opencv/php-opencv-packages/master/opencv_4.5.0_amd64.deb && dpkg -i opencv_4.5.0_amd64.deb && rm opencv_4.5.0_amd64.deb
RUN apt-get install -y git
RUN git clone https://github.com/php-opencv/php-opencv.git
RUN cd php-opencv && git checkout php7.4 && phpize && ./configure --with-php-config=/usr/bin/php-config && make && make install

Here's the error I got:

configure: error: Cannot find php-config. Please use --with-php-config=PATH

I've compiled extensions before and have never used the --with-php-config option before so I tried to remove that and still got an error:

/php-opencv/source/opencv2/core/opencv_mat.cc: In function 'void opencv_mat_update_property_by_c_mat(zval*, cv::Mat*)':

In file included from /usr/local/include/php/main/php.h:35,

Any ideas?

FROM php:8.0

and

RUN cd php-opencv && git checkout php7.4

Any ideas?

PS: If you have problem with creating your own docker file try to use these:

If you are using ono of the official php Docker files (For example FROM php:8.0), the location of php-config is /usr/local/bin/php-config. So the command to build php-opencv is:

RUN cd php-opencv && phpize && ./configure --with-php-config=/usr/local/bin/php-config && make
