I’m trying to add the GD extension to my php on my symfony project. My symfony project is configured with docker via this package https://github.com/dunglas/symfony-docker on windows with WSL. But when I run the “docker-php-ext-install gd” command, I get this error: “Package ‘zlib’, required by ‘virtual:world’, not found”.
Unfortunately, I don’t really understand what I’m supposed to do.

I tried adding this to my Dockerfile:

    RUN apk add --no-cache 
    zlib-dev 
    libpng-dev
    build-base
    wget
    tar
    make
&& wget https://github.com/libgd/libgd/releases/download/gd-2.3.3/libgd-2.3.3.tar.gz 
&& tar -xf libgd-2.3.3.tar.gz 
&& cd libgd-2.3.3 
&& ./configure --with-freetype --with-jpeg 
&& make 
&& make install 
&& docker-php-ext-configure gd --with-freetype --with-jpeg 
&& docker-php-ext-install -j$(nproc) gd zlib

But it doesn’t seem to work. Thank you for your help.
