Debian reports that libxml2 is dropping the xml2-config binary: Date: Mon, 20 Jan 2020 20:42:47 +0100 From: Mattia Rizzolo <mat...@debian.org> Reply-To: Mattia Rizzolo <mat...@debian.org>, 949...@bugs.debian.org Subject: Bug#949428: postgresql-12: FTBFS with libxml2 2.9.10 (uses xml2-config)
Source: postgresql-12 Version: 12.1-2 Severity: important Tags: ftbfs User: libx...@packages.debian.org Usertags: ftbfs-2.9.10 xml2-config Dear maintainer, your package is using `xml2-config` to detect and use libxml2. I'm removing that script, so please update your build system to use pkg-config instead. The libxml2 package in experimental already doesn't ship the xml2-config script. Attached is the full build log, hopefully relevant excerpt follows: checking for xml2-config... no ... configure: error: header file <libxml/parser.h> is required for XML support [...] ----- End forwarded message ----- Luckily the ./configure script is compatible enough so that this hack works: (tested on master) ./configure --with-libxml XML2_CONFIG='pkg-config libxml-2.0' [...] checking for XML2_CONFIG... pkg-config libxml-2.0 [...] checking for xmlSaveToBuffer in -lxml2... yes [...] checking libxml/parser.h usability... yes checking libxml/parser.h presence... yes checking for libxml/parser.h... yes We should teach configure.in to recognize that natively as well, I guess.
