Linking error on Alpine image for PHP 7.4 #937
Description
Hello. I'm trying to build an extension for Cassandra for PHP 7.4 on Alpine-based image. The compilation is successful, but there is an error when trying to run PHP with an extension:
PHP Warning: PHP Startup: Unable to load dynamic library 'cassandra.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190902/cassandra.so (Error relocating /usr/local/lib/php/extensions/no-debug-non-zts-20190902/cassandra.so: php_error_docref0: symbol not found), /usr/local/lib/php/extensions/no-debug-non-zts-20190902/cassandra.so.so (Error loading shared library /usr/local/lib/php/extensions/no-debug-non-zts-20190902/cassandra.so.so: No such file or directory)) in Unknown on line 0

The same build for the same alpine version on PHP 7.3 goes successfully. Also, the build for Debian-based image on PHP 7.4 also finishes successfully and works fine. So it seems like there is some problem with php:7.4-alpine.
How to build
docker run --rm -it php:7.4-alpine sh
docker-php-source extract \
&& apk add --no-cache --virtual .cassandra-deps libressl-dev libuv-dev cassandra-cpp-driver-dev gmp-dev \
&& curl -L -o /tmp/cassandra.tar.gz "https://github.com/datastax/php-driver/archive/24d85d9f1d.tar.gz" \
&& mkdir /tmp/cassandra \
&& tar xfz /tmp/cassandra.tar.gz --strip 1 -C /tmp/cassandra \
&& rm -r /tmp/cassandra.tar.gz \
&& mv /tmp/cassandra/ext /usr/src/php/ext/cassandra \
&& rm -rf /tmp/cassandra \
&& docker-php-ext-install cassandra
The same build for php:7.3-alpine will finish successfully.
