Symptoms
Attempting to install PECL modules for ALT-PHP versions results in a failure with the message:
configure.ac:12: error: Autoconf version 2.68 or higher is required
Description
On CloudLinux 6 servers, it was found that PHPIZE for ALT-PHP is configured to utilize the Autotools package provided by the operating system.
# rpm -q autoconf
autoconf-2.63-5.1.el6.noarch
This is an older version and can cause certain PECL modules to fail to compile. CloudLinux 6 already ships with a newer version of Autotools, however, it appears to not be in use by the PHPIZE configuration.
# rpm -qf /opt/rh/autotools-latest/root/usr/bin/autoconf
autotools-latest-autoconf-2.69-4.el6.cloudlinux.noarch
/opt/cloudlinux/alt-php56/root/usr/bin/phpize:123: test -z "$PHP_AUTOHEADER" && PHP_AUTOHEADER=autoheader
/opt/cloudlinux/alt-php70/root/usr/bin/phpize:122: test -z "$PHP_AUTOCONF" && PHP_AUTOCONF=autoconf
The CloudLinux team has been notified about this.
Workaround
Manually modify the PHPIZE script to ensure the newer Autotools binaries are used.
Example on ALT-PHP70:
Locate the following lines inside the file:
/opt/cloudlinux/alt-php70/root/usr/bin/phpize
For ALT-PHP70, the lines we need to modify are lines 122 & 123:
122: test -z "$PHP_AUTOCONF" && PHP_AUTOCONF=autoconf
123: test -z "$PHP_AUTOHEADER" && PHP_AUTOHEADER=autoheader
Replace them with the following:
122: test -z "$PHP_AUTOCONF" && PHP_AUTOCONF=/opt/rh/autotools-latest/root/usr/bin/autoconf
123: test -z "$PHP_AUTOHEADER" && PHP_AUTOHEADER=/opt/rh/autotools-latest/root/usr/bin/autoheader
(Please note that any updates to these packages may overwrite the changes until CloudLinux addresses the issue)
