PHP intl extension in Docker container
问题 I'm trying to load the intl PHP extension in my Docker container, but it doesn't seem to work. Have already tried this https://github.com/docker-library/php/issues/57 but I still get the same error message: configure: error: in `/usr/src/php/ext/intl': configure: error: C++ preprocessor "/lib/cpp" fails sanity check See `config.log' for more details My Docker file looks like this: RUN apt-get -y update \ && apt-get install -y libicu-dev\ && docker-php-ext-configure intl \ && docker-php-ext
