On PHP 7.3 is working.

I'm not sure where it's looking for the libraries, but they're in the same place in 7.3 /usr/lib/x86_64-linux-gnu/

FROM php:7.4-rc

RUN apt update && apt install -y --no-install-recommends \
        libc-client-dev \
        libkrb5-dev \
        ; \
        rm -rf /var/lib/apt/lists/*

RUN docker-php-ext-configure imap --with-kerberos --with-imap-ssl

Getting log output of docker-php-ext-configure between 7.3 and 7.4-rc:

$ diff -y <(docker exec f311f137216e cat /usr/src/php/ext/imap/config.log) <(docker exec 566e82137a78 cat /usr/src/php/ext/imap/config.log) > diff.log

7.3 left, 7.4-rc right

So this is bug of php-src or dockerfile ?
You confirmed my bug, yes ?

[wglambert]

I'd imagine this is an issue with php:7.4-rc upstream. I don't think there's anything we've omitted or modified between the two that would have caused this

[michaljusiega]

Okey, thank you for answer ;)

[wglambert]

I noticed in one section there exists some new variables in php:7.4-rc: OPENSSL_LIBS

ac_cv_env_LIBS_set=                                             ac_cv_env_LIBS_set=
ac_cv_env_LIBS_value=                                           ac_cv_env_LIBS_value=
                                                              > ac_cv_env_OPENSSL_CFLAGS_set=
                                                              > ac_cv_env_OPENSSL_CFLAGS_value=
                                                              > ac_cv_env_OPENSSL_LIBS_set=
                                                              > ac_cv_env_OPENSSL_LIBS_value=

I'm not sure where to assign that at, as it doesn't appear to read it from the environment variables. I'm not terribly familiar with php

Seems like it's normal for these values to be unset, looking at other builds with the variable ac_cv_env_OPENSSL_LIBS_value in google shows them all unset.

[michaljusiega]

And I just don't know the language in which this configuration is described, so I won't help much in this issue.

I prepared my project from 7.3.9-apache-stretch to 7.4.0-rc-apache-buster.
The configuration of the extensions, as I said, was the same. It wasn't until IMAP that "something went wrong".

However, I prefer to stay with pure PHP.
I hope you will find a solution ;)

[wglambert]

It looks like where 7.4-rc added those OPENSSL_LIBS variables that it dropped OPENSSL_INCDIR_OPT='-I/usr/include'.

An attempt to adjust for that

# docker-php-ext-configure imap --with-kerberos --with-imap-ssl --with-libdir=/usr/include/
. . .
configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.

Another try

# find / -name libc-client.a
/usr/lib/libc-client.a

# cp /usr/lib/libc-client.a /usr/include/

# docker-php-ext-configure imap --with-kerberos --with-imap-ssl --with-libdir=/usr/include/
. . .
configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.

I'm not sure why the configure script can't detect the --with-openssl of PHP itself properly, but I was able to get it to build successfully with the following:

FROM php:7.4-rc

RUN set -eux; \
	apt-get update; \
	apt-get install -y --no-install-recommends \
		libc-client-dev \
		libkrb5-dev \
	; \
	rm -rf /var/lib/apt/lists/*

RUN set -eux; \
	PHP_OPENSSL=yes docker-php-ext-configure imap --with-kerberos --with-imap-ssl; \
	docker-php-ext-install imap

$ docker run --rm 48ea37b4a33e php -m | grep -i imap
imap
$ docker run --rm 48ea37b4a33e php -i | grep -i imap
Additional .ini files parsed => /usr/local/etc/php/conf.d/docker-php-ext-imap.ini,
Protocols => dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtmp, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp
imap
IMAP c-Client Version => 2007f
imap.enable_insecure_rsh => Off => Off

[michaljusiega]

I confirm, PHP_OPENSSL=yes resolve issue ;>

[tianon]

Excellent, thanks for confirming and glad we could figure out a solution. 👍
