PHP 8 compatibility

[Arthur Schopenhauer]

Try to insatll in Docker:

FROM php:8.0.6-cli

RUN apt-get update && apt-get install -y \
    libevent-dev

RUN pecl install event && docker-php-ext-enable event

In sesult have error:

Warning: PHP Startup: Unable to load dynamic library 'event' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20200930/event (/usr/local/lib/php/extensions/no-debug-non-zts-20200930/event: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20200930/event.so (/usr/local/lib/php/extensions/no-debug-non-zts-20200930/event.so: undefined symbol: socket_ce)) in Unknown on line 0

Please check out my Bitbucket configuration over here https://bitbucket.org/osmanov/pecl-event/src/a210a5443bbc5f79f099a4f8a402f47a7c31b127/bitbucket-pipelines.yml

There should be little difference with the Dockerfile.

At first glance, however, it seems that you should use either pecl or the built-in docker functions, but not a mix of them. For example, try to use docker-php-ext-install event instead of pecl install event.

I’m create clean repo for demonstrate problem

https://bitbucket.org/artsf/php8_docker_ext-event/

When run `docker-compose up` take result:

\$ docker-compose up

Building php-cli

Step 1/4 : FROM php:8.0.6-cli

---> 8e9df47062cd

Step 2/4 : RUN apt-get update && apt-get install -y build-essential libevent-dev libssl-dev

---> Using cache

Step 3/4 : RUN docker-php-ext-install -j$(nproc) sockets

Step 4/4 : RUN docker-php-source extract && phpize && ./configure --with-event-core --with-event-extra --with-event-openssl && make install && echo 'extension=event.so' > /usr/local/etc/php/conf.d/z-event.ini && docker-php-source delete

Cannot find config.m4.

Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module

ERROR: Service 'php-cli' failed to build : The command '/bin/sh -c docker-php-source extract && phpize && ./configure --with-event-core --with-event-extra --with-event-openssl && make install && echo 'extension=event.so' > /usr/local/etc/php/conf.d/z-event.ini && docker-php-source delete' returned a non-zero code: 1

Also try do this Dockerfile

FROM php:8.0.6-cli

RUN apt-get update && apt-get install -y \
    libevent-dev \
    libssl-dev

RUN docker-php-ext-install -j$(nproc) event

And have this output:

\$ docker-compose up

Building php-cli

Step 1/3 : FROM php:8.0.6-cli

---> 8e9df47062cd

Step 2/3 : RUN apt-get update && apt-get install -y libevent-dev libssl-dev

---> Using cache

---> 196bcb3b70e6

Step 3/3 : RUN docker-php-ext-install -j$(nproc) event

---> Running in c77c6be86bbd

error: /usr/src/php/ext/event does not exist

usage: /usr/local/bin/docker-php-ext-install [-jN] [--ini-name file.ini] ext-name [ext-name ...]

ie: /usr/local/bin/docker-php-ext-install gd mysqli

‌ /usr/local/bin/docker-php-ext-install pdo pdo_mysql

‌ /usr/local/bin/docker-php-ext-install -j5 gd mbstring mysqli pdo pdo_mysql shmop

if custom ./configure arguments are necessary, see docker-php-ext-configure

Possible values for ext-name:

bcmath bz2 calendar ctype curl dba dom enchant exif ffi fileinfo filter ftp gd gettext gmp hash iconv imap intl json ldap mbstring mysqli oci8 odbc opcache pcntl pdo pdo_dblib pdo_firebird pdo_mysql pdo_oci pdo_odbc pdo_pgsql pdo_sqlite pgsql phar posix pspell readline reflection session shmop simplexml snmp soap sockets sodium spl standard sysvmsg sysvsem sysvshm tidy tokenizer xml xmlreader xmlwriter xsl zend_test zip

Some of the above modules are already compiled into PHP; please check

the output of "php -i" to see which modules are already loaded.

Okay, here is what you need:

FROM php:8.0.6-cli

RUN apt-get update && apt-get install -y build-essential libevent-dev libssl-dev

RUN docker-php-ext-install sockets \
    && docker-php-ext-enable --ini-name 0-sockets.ini sockets

RUN pecl install event \
    && docker-php-ext-enable --ini-name z-event.ini event

[Arthur Schopenhauer]

This works! Thanks!
