Unable to install IMAP extension (Alpine Linux)

[mvdstam]

In continuation of #120, I'm getting the same error when trying to install the imap extension on the alpine linux image:

configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information.

My Dockerfile:

FROM php:5-fpm-alpine

RUN apk upgrade --update && apk add \
      php5-imap autoconf file g++ gcc binutils isl libatomic libc-dev musl-dev make re2c libstdc++ libgcc binutils-libs mpc1 mpfr3 gmp libgomp \

      libjpeg-turbo-dev \
      libltdl \
      libmcrypt-dev \
      libpng-dev \

    && docker-php-ext-configure imap --with-imap --with-imap-ssl \
    && docker-php-ext-install imap \

    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd \
    && apk del autoconf file g++ gcc binutils isl libatomic libc-dev musl-dev make re2c libstdc++ libgcc binutils-libs mpc1 mpfr3 gmp libgomp \
    && rm -rf /var/cache/apk/*

COPY ./php.ini /usr/local/etc/php/php.ini

Can anyone point me in the right direction to get this working? Maybe @tianon? 😄 Thanks!

Hi @mvdstam ,

libc-client-dev package doesn't exist on alpine.
You need to install imap-dev

Enjoy ! 😄

Hey @Yanntech!

Thanks a lot for helping out. Still getting used to Alpine linux. For those interested, my full Dockerfile is as follows:

FROM php:5-fpm-alpine

RUN apk upgrade --update && apk add \
      autoconf file g++ gcc binutils isl libatomic libc-dev musl-dev make re2c libstdc++ libgcc binutils-libs mpc1 mpfr3 gmp libgomp \
      coreutils \
      freetype-dev \
      libjpeg-turbo-dev \
      libltdl \
      libmcrypt-dev \
      libpng-dev \
      imap-dev \
      openssl-dev \
    && docker-php-ext-install iconv mcrypt mysqli mysqlnd pdo pdo_mysql zip bcmath \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd \
    && docker-php-ext-configure imap --with-imap --with-imap-ssl \
    && docker-php-ext-install imap

RUN pecl install xdebug \
    && docker-php-ext-enable xdebug \
    && apk del autoconf file g++ gcc binutils isl libatomic libc-dev musl-dev make re2c libstdc++ libgcc binutils-libs mpc1 mpfr3 gmp libgomp \
    && rm -rf /var/cache/apk/*

COPY ./php.ini /usr/local/etc/php/php.ini

Thanks again!

Still having a problem installing IMAP on Alpine PHP image. Here is my Dockerfile:

And warning:

PHP Warning:  PHP Startup: Unable to load dynamic library 'imap.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20180731/imap.so (Error loading shared library libc-client.so.1: No such file or directory (needed by /usr/local/lib/php/extensions/no-debug-non-zts-20180731/imap.so)), /usr/local/lib/php/extensions/no-debug-non-zts-20180731/imap.so.so (Error loading shared library /usr/local/lib/php/extensions/no-debug-non-zts-20180731/imap.so.so: No such file or directory)) in Unknown on line 0

Includind libc-client is impossible. What can I do to make it work?

[yosifkit]

@DarthLegiON, probably need to keep imap-dev installed since it is providing /usr/lib/libc-client.so (or just c-client for /usr/lib/libc-client.so.1): https://pkgs.alpinelinux.org/contents?file=libc-client.so*&path=&name=&branch=v3.10&arch=x86_64

You may also want to combine your RUN lines into a single line, otherwise you won't see any space saving from the deletes.

[DarthLegiON]

@yosifkit thanks for advices!

Minimal Dockerfile for reference if someone have the same problem:

https://github.com/fox91/docker-php-extensions/blob/main/8.0/alpine3.14/imap/Dockerfile

FROM php:8.0-alpine3.14

# PHP ext-imap
RUN set -eux; \
  persistentDeps=" \
    c-client \
  "; \
  buildDeps=" \
    imap-dev \
    krb5-dev \
    openssl-dev \
  "; \
  apk add --no-cache --virtual .imap-persistent-deps ${persistentDeps}; \
  apk add --no-cache --virtual .imap-build-deps ${buildDeps}; \
  \
  docker-php-ext-configure imap \
    --with-imap-ssl \
    --with-kerberos \
  ; \
  docker-php-ext-install -j$(nproc) imap; \
  \
  apk del --no-cache --no-network .imap-build-deps

Tested with PHP 7.3, 7.4 and 8.0 on alpine3.14.

c-client as a persistent dep fixed the issue.
