php-fpm build fails with php7.4 and IMAP enabled

[lyimmi]

Info:

• Docker version ($ docker --version): Docker version 19.03.5, build 633a0ea838
• Laradock commit ($ git rev-parse HEAD): ad2b455
• System info (Mac, PC, Linux): Linux
• System info disto/version: Ubuntu 18.04.3 LTS

Issue:

Cannot build php7.4 with IMAP enabled. php7.3 works fine.

---

Expected behavior:

I expected the php-fpm container to be built.

---

Reproduce:

1. clone the repository
2. copy env-example => .env
3. set PHP_FPM_INSTALL_IMAP=true
4. docker-compose build php-fpm
5. get an error as follows:

...

Check the path given to --with-openssl-dir and output in config.log)

ERROR: Service 'php-fpm' failed to build: The command '/bin/sh -c if [ ${INSTALL_IMAP} = true ]; then     apt-get install -y libc-client-dev libkrb5-dev &&     docker-php-ext-configure imap --with-kerberos --with-imap-ssl &&     docker-php-ext-install imap ;fi' returned a non-zero code: 1

Relevant Code:

/laradock/php-fpm/Dockerfile:684

###########################################################################
# IMAP:
###########################################################################

ARG INSTALL_IMAP=false

RUN if [ ${INSTALL_IMAP} = true ]; then \
    apt-get install -y libc-client-dev libkrb5-dev && \
    docker-php-ext-configure imap --with-kerberos --with-imap-ssl && \
    docker-php-ext-install imap \
;fi

---

Fixed Code:

I managed to build the container with the modification below. I'm not an expert in this area so that is why I didn't made a pull request, it works for me, but I'm not sure this is the proper solution.

    docker-php-ext-install imap \
;fi

Had same issue and solved adding PHP_OPENSSL=yes, as @lyimmi had exposed.
