When I download the source of PECL imagick and compile it using phpize
I get an error "undefined macro: _m4_divert_diversion".

• CentOS6.7


• PHP7.3


• autoconf 2.71 → 2.69


• m4 1.4.13 → 1.4.18


• libtool 2.2.6b

wget htps://pecl.php.net/get/imagick-3.7.0.tgz

tar -xzvf imagick-3.7.0.tgz

cd imagick-3.7.0



sudo /usr/local/php7.3/bin/phpize



Configuring for:

PHP Api Version 20180731

Zend Module Api No: 20180731

Zend Extention Api No: 320180731

I have changed the versions of autoconf and m4 to 2.69 and 1.4.18 respectively, but the error has not changed.

I would appreciate it if you could let me know if there is something suspicious.

My Answer:
"Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable."
