Reading Exif data is not supported by this PHP installation.

[devSarry]

I'm running into this issue with a docker container I'm using laradocks that I suspect is comping from here. From what I understand some extensions depend on others to load properly. http://php.net/manual/en/exif.installation.php

[daohoangson]

You can create your own Dockerfile and run this command to have the EXIF extension installed:

docker-php-ext-install exif

Check the instruction here.

[devSarry]

laradock builds its docker file using compose so here's the relevent section

#####################################
# Exif:
#####################################

ARG INSTALL_EXIF=false
RUN if [ ${INSTALL_EXIF} = true ]; then \
    # Enable Exif PHP extentions requirements
    docker-php-ext-install exif && \
     docker-php-ext-enable exif \
;fi

that get called from here

        environment:

            - PHP_IDE_CONFIG=serverName=laravel

Look right?

[tianon]

Yeah, except that docker-php-ext-install already invokes docker-php-ext-enable (

php/docker-php-ext-install

Lines 104 to 108 in 21b6fad

	find modules \
	-maxdepth 1 \
	-name '*.so' \
	-exec basename '{}' ';' \
	| xargs -r docker-php-ext-enable

), so there's no need to do both. 👍

[suncoastkid]

Same issue:

Service 'php-fpm' failed to build: One or more build-args [INSTALL_EXIF] were not consumed, failing build.

[yosifkit]

This really seems like an issue you are having with using laradock, but I'll see what I can help with.

@suncoastkid are you perchance using their 5.6 Dockerfile? I noticed that it does not contain any reference to an arg of INSTALL_EXIF while the 7.0 Dockerfile does; which could account for the failed build where the "build-arg [was] not consumed". I'm not sure why their Dockerfiles differ since you can install exif in the php:5 image:

$ docker run -it --rm php:5 bash
root@352df2afc52c:/# docker-php-ext-install exif
+ cd exif

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

No, using

[tianon]

This is solved -- the appropriate solution (as noted above), is to include RUN docker-php-ext-install exif in your derivative Dockerfile. 👍

Hi,
sorry to dig out an old issue, but I can't get it working. I added RUN docker-php-ext-install exif as recommended but it's not working: Call to undefined function exif_imagetype()

During the build, it seems to be doing something around exif:

But no success.

RUN docker-php-ext-install exif
RUN pecl install mcrypt-1.0.1
RUN docker-php-ext-enable mcrypt

Thanks for your help!

[tianon]

@TdyP according to http://us2.php.net/manual/en/function.exif-imagetype.php#100734, you might need to also enable mbstring -- have you tried that?

[TdyP]

Yep, mbstring is already enabled

[tianon]

I'm not able to reproduce; with the following Dockerfile:

FROM php:7.2
RUN docker-php-ext-install exif

I get this result:

php > var_dump(exif_imagetype('/usr/share/pixmaps/debian-logo.png'));
int(3)

(Looking at http://us2.php.net/exif_imagetype, 3 corresponds to IMAGETYPE_PNG.)

[TdyP]

OK
I'm using php:7-fpm, I don't know if it makes any difference to enable extensions

[TdyP]

OK.. There's something I don't get about Docker.
docker-compose build with appropriate Dockerfile=> doesn't work
Restart Docker, docker-compose up=> now it's working

Anyway, problem solved, thanks for your help!
