The docbook-dtds package patches docbook SGML catalogs to remove ISO entities declarations, and replace DTDDECL statement with SGMLDECL statement for docbook 3.0, 3.1, 4.0 and 4.1: - https://src.fedoraproject.org/rpms/docbook-dtds/blob/master/f/docbook-dtd30-sgml-1.0.catalog.patch - https://src.fedoraproject.org/rpms/docbook-dtds/blob/master/f/docbook-dtd31-sgml-1.0.catalog.patch - https://src.fedoraproject.org/rpms/docbook-dtds/blob/master/f/docbook-dtd40-sgml-1.0.catalog.patch - https://src.fedoraproject.org/rpms/docbook-dtds/blob/master/f/docbook-dtd41-sgml-1.0.catalog.patch Unfortunately, this also has the unexpected side effect of breaking linuxdoc-tools processing when this package is also installed. Without docbook-dtds installed: [guillaume@sp linuxdoc-tools-0.9.72]$ /usr/local/bin/linuxdoc -B html doc/guide.sgml Processing file doc/guide.sgml -> OK With docbook-dtds installed: [guillaume@sp linuxdoc-tools-0.9.72]$ LC_ALL=C /usr/local/bin/linuxdoc -B html doc/guide.sgml Processing file doc/guide.sgml nsgmls:<OSFD>0:8:8:E: document type does not allow element "ARTICLE" here; assuming missing "LINUXDOC" start-tag nsgmls:<OSFD>0:10:6:E: document type does not allow element "TITLE" here; assuming missing "TITLEPAG" start-tag nsgmls:<OSFD>0:11:7:E: document type does not allow element "AUTHOR" here nsgmls:<OSFD>0:19:5:E: document type does not allow element "DATE" here nsgmls:<OSFD>0:20:9:E: document type does not allow element "ABSTRACT" here nsgmls:<OSFD>0:29:4:E: document type does not allow element "TOC" here nsgmls:<OSFD>0:31:5:E: document type does not allow element "SECT" here nsgmls:<OSFD>0:31:6:E: character data is not allowed here ... -> failure It seems the problem comes from multiple occurrences of SGMLDECL "docbook.dcl" statements when loading the global SGML catalog. Commenting out offending docbook catalogs (4.2 and new versions are not affected), or reverting the problematic part of the patch is enough to fix. I don't have enough SGML knowledge to understand if the root issue comes from redhat package changes, or linuxdoc-tools itself. I tested the issue on Centos and Mageia, not on Fedora directly, but that's the same package and the same patch.
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
This bug is still there on Fedora 27 and causing problems whenever linuxdoc is to be used. Solution is needed.
It would be really nice if this bug was fixed. I can't build libuser from source w/o workarounds due to the issue.
Ok, will try to drop replacement of DTDDECL statement with SGMLDECL statement - it is not present in 4.2+ sgml catalogs anyway - and I see no reason for it. Anyway, there was one more typo (sgml docbook 3.0 instead of 3.1 in one of the patch) - fixed together. Sorry for delay. Built in Rawhide...
I buuilt docbook-dtds-1.0-70 on Fedora 28 and it did not resolve my problem. I am still getting problem with SECT when compiling an application: Processing file FAQ.sgml nsgmls:<OSFD>0:228:7:E: document type does not allow element "SECT" here nsgmls:<OSFD>0:239:7:E: document type does not allow element "SECT" here nsgmls:<OSFD>0:311:7:E: document type does not allow element "SECT" here nsgmls:<OSFD>0:352:7:E: document type does not allow element "SECT" here nsgmls:<OSFD>0:434:9:E: end tag for "ITEMIZE" omitted, but its declaration does not permit this nsgmls:<OSFD>0:203:8: start tag was here LinuxdocTools::process_file: nsgmls failed with exit status 1. Aborting ... Removing docbook-dtds rpm temporarily allows for compilation.
This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
