Bug #79347 [Com]: Compile error caused by libxml2 2.9.9

Edit report at https://bugs.php.net/bug.php?id=79347&edit=1 ID: 79347 Comment by: omars@php.net Reported by: markus dot tobatz at gmail dot com Summary: Compile error caused by libxml2 2.9.9 Status: Open Type: Bug Package: Compile Failure Operating System: Debian Stretch PHP Version: 7.3.15 Block user comment: N Private report: N New Comment: I will follow up, thank you Previous Comments: ------------------------------------------------------------------------ [2020-05-20 17:54:32] php dot net at tylercollier dot com TLDR: I had to install pkg-config, and then follow markus's steps. I had this issue too. Thanks to markus for the steps to fix. When he mentioned pkg.m4, I searched the internet and found that it should be at /usr/share/aclocal/pkg.m4, and I had no such file there. So I installed pkg-config. Then using his steps would work. I did aclocal and autoreconf (-f was not necessary). Then ./configure worked. ------------------------------------------------------------------------ [2020-03-05 15:15:09] markus dot tobatz at gmail dot com I don't know what is going on and what's the reason, but I got it working the following way. I've downgraded from PHP7.4 to PHP7.3.15 again. As install via "pecl install solr" fails again, I tried it manually, getting the master tree from github. Documentation says you have to execute "phpize && configure && make" which fails with same error as with PECL. After searching the internet I got a hint that there seems to be an issue with "pkg.m4". So I executed "aclocal && autoreconf -f" directly after "phpize" and then "configure" and "make" ran without any problems and compiled "solr.so". ------------------------------------------------------------------------ [2020-03-05 13:09:26] markus dot tobatz at gmail dot com I've upgraded all PHP components to version 7.4 now. Solr package is installable via PECL now (no warning or something else while compiling), but class SolrDismaxQuery is now missing: "Uncaught Error: Class 'SolrDisMaxQuery' not found" But it's not an option to upgrade all machines to PHP 7.4. I want to compile it on PHP 7.3 which still was working some weeks before. ------------------------------------------------------------------------ [2020-03-05 07:53:08] cmb@php.net From the error message, it seems that PHP 7.4 is somehow involved in the build process. ------------------------------------------------------------------------ [2020-03-05 07:17:57] markus dot tobatz at gmail dot com Description: ------------ # php -v PHP 7.3.15-4+0~20200224.55+debian9~1.gbpbea824 (cli) (built: Feb 24 2020 18:39:46) ( NTS ) # uname -a Linux vm4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux # dpkg -l | grep libxml2 ii libxml2:amd64 2.9.9+dfsg-1+0~20200226.5+debian9~1.gbp3b6674 amd64 GNOME XML library ii libxml2-dev:amd64 2.9.9+dfsg-1+0~20200226.5+debian9~1.gbp3b6674 amd64 Development files for the GNOME XML library # pecl install solr downloading solr-2.5.0.tgz ...
