I'm able to upgrade the cURL binary and libs, however PHP still utilizes the old version.

cURL binary and libs PHP cURL

I'm building on top of the official php:7.0-fpm docker container.

First, I've upgraded cURL:

RUN curl -fsSL 'https://curl.haxx.se/download/curl-7.50.3.tar.gz' -o curl.tar.gz \
    && mkdir -p curl \
    && tar -xf curl.tar.gz -C curl --strip-components=1 \
    && rm curl.tar.gz \
    && ( \
        cd curl \
        && make \
        && make install \
        && ldconfig \
    ) \
    && rm -r curl

I've tried:

  1. Use libtool

    cd curl \
&& ./buildconf \
&& ./configure \
# ...

  2. Re-install curl for PHP

    RUN docker-php-ext-configure curl --with-curl=/usr/local/lib
RUN docker-php-ext-install curl

But this throws the error/warning: warning: curl (curl.so) is already loaded! and eventually just ignores that I want to reinstall it.

  1. Several smaller random stuff

If possible, I'm looking for a solution that doesn't require a complete recompile of PHP.

  • The cURL PHP extension is linked against the cURL library, just like the cURL binary, however, those too are independent and upgrading either doesn't upgrade the other. So you need to build the PHP extension. Also, you must use https instead. It's a shame for a developer and a security issue to use unencrypted protocols for downloading critical software.

  • Wow, that escalated quickly - but thanks for pointing it out ;) As shown in 2: RUN docker-php-ext-install curl didn't do the trick. Any better ideas? Commented Nov 2, 2016 at 23:34
  • No offense intended ;-) I am not sure if you can compile the curl.so without fully rebuilding PHP from source. Have you tried removing curl before running RUN docker-php-ext..... ? Commented Nov 3, 2016 at 15:49
  • php 7.1 comes with libcurl >= 7.44.0 so never mind :) Commented Nov 14, 2016 at 15:41
