Hi Im trying to install PHP 7.1 or update because im with the version 5.6 and I need the newier version to run some apps. So I followd the howtoforge manual but Im having this error in the configuration. checking for SSL_CTX_set_ssl_version in -lssl... (cached) yes checking whether rfc822_output_address_list function present... no checking whether build with IMAP works... no configure: error: build test failed. Please check the config.log for details. Please if someone can help me. Thanks
