Re: [users@httpd] Problems building httpd-2.4.26 with apr-1.6.2 and apr-util-1.6.0
Hi Libexpat.so is not linked. Xml unresolved error is because of libexpat of apr-util. Thanks Hemant On Jun 23, 2017 9:55 PM, "Martin Knoblauch" wrote: > Hi, > > first post to this lists.

Note this shouldn't be necessary once you've installed libexpat (-dev / -devel depending on your OS conventions.) Expat 2 is finally quite stable and with some luck you can rely on your OS vendor to patch security defects. Once you've installed the dev[el] package, apr should detect expat without hints.
Re: [users@httpd] Problems building httpd-2.4.26 with apr-1.6.2 and apr-util-1.6.0
Hi Eric, sure this works, but it adds an additional dependency (same with relying on the system installed version). When expat was bundled with apr-util I never had to do anything special about it. Likely I never realized that dependency. So, apr-util-1.6.0 surprised me by breaking a year old build process. So my question now is - was the removal of expat from apr-util intentional? I see no mentioning in the release notes.

Re: [users@httpd] Problems building httpd-2.4.26 with apr-1.6.2 and apr-util-1.6.0
Hi William, thanks. Installing "libexpat-devel-2.0.1-88.26.1" on this SLES11 system made httpd build again. Just that I do not like to rely on that kind of stuff. The old behavior of apr-util-1.5.4 was just more convenient :-( Actually never made me realize that "libexpat" is needed.

Re: [users@httpd] Problems building httpd-2.4.26 with apr-1.6.2 and apr-util-1.6.0
Hi Nick, hmm. Maybe I am loosing my eyesight... I looked at both http://www.apache.org/dist/apr/CHANGES-APR-1.6 and http://www.apache.org/dist/apr/CHANGES-APR-UTIL-1.6 and find no mentioning of expat or its removal from the packages. But that is the change-log and I now find it on the apr home page :-) All good now.

That is a problem, fixing this now. Thanks for the report! >From the actual Announcement which we failed to publish to the canonical URL http://www.apache.org/dist/apr/Announcement1.x.txt (I'm fixing this now); The Apache Software Foundation and the Apache Portable Runtime Project are proud to announce the General Availability of version 1.6 of the Apache Portable Runtime libraries. Now available from https://apr.apache.org/ are: * The APR Utilities library (APR-UTIL or APU) version 1.6.0 PRINCIPAL CHANGES IN VERSION 1.6 APR-UTIL-1.6.0 There are a number of updates to how APR-UTIL deals with external dependencies: - XML: - Expat sources are no longer bundled, this is now an external dependency. You must install expat on your system to use APR-UTIL (expat is installed as standard on most systems). If you are building APR-UTIL, you may need to obtain expat 2.2 or later from https://libexpat.github.io/ or depending on your system's packaging policies, install their expat-dev or expat-devel package. Note that 2.2 addressed some security vulnerabilities of earlier libexpat project releases. So there it was covered.
