gd has unrecognized options in PHP 7.4

[patrickomeara]

During an upgrade to PHP 7.4 I can't specify options to docker-php-ext-configure

test Dockerfile below

FROM php:7.4.0-apache

# packages
RUN apt-get update \
  && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends \
  # needed for gd
  libfreetype6-dev \
  libjpeg62-turbo-dev \
  libpng-dev \
  && rm -rf /var/lib/apt/lists/*

# GD
RUN docker-php-ext-configure gd --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-png-dir=/usr \
  && docker-php-ext-install -j "$(nproc)" gd

RUN php -r 'var_dump(gd_info());'

output from step 3

configure: WARNING: unrecognized options: --with-freetype-dir, --with-jpeg-dir, --with-png-dir

output from step 4

}

swapping the base image to php:7.3-apache

no error from docker-php-ext-configure

output from step 4

Has there been an undocumented change to docker-php-ext-configure in 7.4?

[richardbrinkman]

I came accross the same issue. I could repair it by changing the line

docker-php-ext-configure gd --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-png-dir=/usr

into

docker-php-ext-configure gd --with-freetype --with-jpeg

I could not find a --with-png option, but png resizing worked in my case. So maybe png support is a built in default as of PHP 7.4.

A further change I had to make was to include the libonig-dev apt package in order to compile the pdo module.

It's strange that the README.md and the description on Docker Hub don't give examples how to compile pdo and gd properly on PHP 7.4, but only give it for PHP 7.2 (which still works for 7.3 as well).

That has indeed fixed the issue. Thanks @richardbrinkman

This is a change by PHP in Version 7.4
