xmldiff version(s): xmldiff 1.1.2, 1.1.1, 1.1.0
PHP (cli) (built: Feb  5 2020 16:51:32) ( NTS )
Modules installed: calendar Core ctype date dom exif fileinfo filter ftp gettext hash iconv json libxml openssl pcntl pcre PDO Phar posix readline Reflection session shmop SimpleXML sockets sodium SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter xsl Zend OPcache zlib

**Seems related to:**

Repro (on a clean install of 18.04):
1. apt update && apt dist-upgrade -y
2. add-apt-repository ppa:ondrej/php
3. apt update && apt install php7.3 php7.3-dev phpxml -y
4. pecl channel-upgrade
5. pecl install xmldiff -> "recipe for target 'xmldiff.lo' failed"

To confirm, I downloaded the tgz package and tried to manually build:
1. wget
2. tar -xvzf xmldiff-1.1.2.tgz
3. cd xmldiff-1.1.2
4. phpize
5. ./configure
6. make -> "recipe for target 'xmldiff.lo" failed"

I have the full compiler output from the manual build if you would like (it's about 300k, and there is no obvious place to attach it here.)

Please provide the compile error that is printed, there should be something before the "recipe failed", which is just a message from "make".

If you would like to post the full log, I'd suggest

I see a lot of these, so I am also making the output available here.
