Unsupported extensions not loaded for PHP 7.3 (unable to load dynamic library)

[thomas-hiron]

Hi!

I have a problem similar to issue #28, I can't load unsupported extensions (xmlwriter, simplexml, fileinfo, tokenizer).

Here is my Dockerfile:

FROM alpine:3.8

# Add php 7.3 repo from codecasts: https://github.com/codecasts/php-alpine
ADD https://php.codecasts.rocks/php-alpine.rsa.pub /etc/apk/keys/php-alpine.rsa.pub
RUN apk --update add ca-certificates
RUN echo "@php https://php.codecasts.rocks/v3.8/php-7.3" >> /etc/apk/repositories

RUN apk update && apk add --no-cache --update \
            php-fpm@php \
            php-bcmath@php \
            php-mbstring@php \
            php-gd@php \
            php-iconv@php \
            php-intl@php \
            php-pdo@php \
            php-pdo_mysql@php \
            php-soap@php \
            php-xsl@php \
            php-xml@php \
            php-opcache@php \
            php-json@php \
            php-phar@php \
            php-session@php \
            php-curl@php \
            php7-xmlwriter \
            php7-simplexml \
            php7-fileinfo \
            php7-tokenizer \
            curl \
            bash \
        && rm -rf /var/cache/apk/*

RUN ln -s /usr/bin/php7 /usr/bin/php

And here is the result of php -v:

PHP Warning:  PHP Startup: Unable to load dynamic library 'fileinfo.so' (tried: /usr/lib/php7/modules/fileinfo.so (Error relocating /usr/lib/php7/modules/fileinfo.so: _zval_ptr_dtor: symbol not found), /usr/lib/php7/modules/fileinfo.so.so (Error loading shared library /usr/lib/php7/modules/fileinfo.so.so: No such file or directory)) in Unknown on line 0

What can be the problem? Thanks!

            php7-xmlwriter \
            php7-simplexml \
            php7-fileinfo \
            php7-tokenizer \

you forgot the @php on those, but you don't actually need cause they are bundle on core php build.

some of thoses like tokenizer are already bundled into php core ext, no need to install.

the ones you can't find on @php are most likelly to be bundled.

you can also check the directory listing to see the extensions available there.

Thanks

What do you mean by the ones who need to be bundled?
How is this related to the warning messages?

@thomas-hiron When you look at the output of the apk add, you will probably notice that these 4 packages are not installed from codecasts, but from the main alpine repository, in version 7.2.x. Simply remove these 4 lines from your Dockerfile and it will work. These extension are already available, they are part of php7-fpm@php (fpm) and php7@php (cli).

I will try that and close if solved! Thank you
