Having problem installing intl

[ksowa]

Hi,
as I'm working on international project, I'm taking the advantage of the intl PHP extension. Symfony also recommends to install it.

I tried many different options, but couldn't get it installed.

First of all I had to install libicu-dev package:
docker-compose exec php apt install libicu-dev

Then I tried to do similar thing for intl:
docker-compose exec php apt install php7.1-intl
but the error says the package could not be found.

I even added ppa:ondrej/php repository, but it says:

W: Failed to fetch http://ppa.launchpad.net/ondrej/php/ubuntu/dists/jessie/main/binary-amd64/Packages  404  Not Found
W: Failed to fetch http://ppa.launchpad.net/ondrej/php5-5.6/ubuntu/dists/jessie/main/binary-amd64/Packages  403  Forbidden

I also tried to install that by PECL:
docker-compose exec php pecl install intl
but it throws the following error:

compilation terminated.
Makefile:194: recipe for target 'php_intl.lo' failed
make: *** [php_intl.lo] Error 1
ERROR: `make' failed

Do you have any idea of how to make this working?

Hi,

I think you should run docker-php-ext-install command in your PHP container.
https://github.com/maxpou/docker-symfony/blob/master/php7-fpm/Dockerfile#L22
Then update Dockerfile.

Thanks @maxpou , it worked. I tried this solution at a very beginning, but it didn't work without the libicu-dev package. After installing it, I was trying other approaches and forgot about the easiest path.

I've created pull request for this - https://github.com/maxpou/docker-symfony/pull/79/files

I think it's worth merging it, as Symfony recommends intl extension, anyway.

The other thing I was struggling with, but less important, is this message printed by bin/symfony_requirements:

 * intl ICU version installed on your system is outdated (52.1) and
   does not match the ICU data bundled with Symfony (60.1)
   > To get the latest internationalization data upgrade the ICU
   > system package and the intl PHP extension.

I was trying to update the ICU package, but with no success. Do you think it would be doable?

Thanks for your great work on the integration. It's really useful!
