Hi, I'm trying to write a small article using lyx with the "DocBook article (SGML)" class, with dissapointing results. I can view as dvi, postscript or pdf; but the TOC and the images fail to be produced. I can not even view as html, no file. However, I can export to sgml (or DocBook), and from that file manually export to html using "docbook2html texto.sgml" on a console, and I get better results: at least the html files are produced. The TOC is there, but the images lack the extension on their names, so that the html files have to be manually edited. Using "sgml2html texto.sgml" produces the same bad results. But there is worse. The html production stops, as the conversion complains with: jade:I: maximum number of errors (200) reached; change with -E option and the html document stays incomplete. Thus, I edited the file "/usr/share/sgml/docbook/utils-0.6.6/backends/html" and changed a line; it said: $SGML_JADE -t sgml $SGML_ARGUMENTS it reads now: $SGML_JADE -E 500 -t sgml $SGML_ARGUMENTS So now the document is fully parsed, but with many errors; it begins as follows: jade:/home/cer/lyx/texto.sgml:1:58:W: cannot generate system identifier for public te xt "-//OASIS//DTD DocBook V4.1//EN" jade:/home/cer/lyx/texto.sgml:1:58:E: reference to entity "ARTICLE" for which no system identifier could be generated jade:/home/cer/lyx/texto.sgml:1:0: entity was defined here jade:/home/cer/lyx/texto.sgml:1:58:E: DTD did not contain element declaration for document type name jade:/home/cer/lyx/texto.sgml:3:14:E: there is no attribute "LANG" jade:/home/cer/lyx/texto.sgml:3:18:E: element "ARTICLE" undefined jade:/home/cer/lyx/texto.sgml:5:12:E: element "ARTICLEINFO" undefined jade:/home/cer/lyx/texto.sgml:5:19:E: element "TITLE" undefined [etc] Using openjade as parser yields the same: openjade:/home/cer/lyx/texto.sgml:1:58:W: cannot generate system identifier for public text "-//OASIS//DTD DocBook V4.1//EN" openjade:/home/cer/lyx/texto.sgml:1:58:E: reference to entity "ARTICLE" for which no system identifier could be generated openjade:/home/cer/lyx/texto.sgml:1:0: entity was defined here openjade:/home/cer/lyx/texto.sgml:1:58:E: DTD did not contain element declaration for document type name openjade:/home/cer/lyx/texto.sgml:3:14:E: there is no attribute "LANG" openjade:/home/cer/lyx/texto.sgml:3:18:E: element "ARTICLE" undefined openjade:/home/cer/lyx/texto.sgml:5:12:E: element "ARTICLEINFO" undefined openjade:/home/cer/lyx/texto.sgml:5:19:E: element "TITLE" undefined openjade:/home/cer/lyx/texto.sgml:5:77:E: element "AUTHOR" undefined openjade:/home/cer/lyx/texto.sgml:5:99:E: element "ABSTRACT" undefined openjade:/home/cer/lyx/texto.sgml:5:105:E: element "PARA" undefined openjade:/home/cer/lyx/texto.sgml:5:218:E: element "PARA" undefined openjade:/home/cer/lyx/texto.sgml:5:223:E: element "TOC" undefined openjade:/home/cer/lyx/texto.sgml:6:6:E: element "SECT1" undefined openjade:/home/cer/lyx/texto.sgml:6:13:E: element "TITLE" undefined [etc] So I guess there is something very wrong on some package. It recognizes nothing! :-/ My system is Suse 7.3, but I remember I tried with 7.1 with similar results. Lyx was 1.1.6fix2; with this version, I could not even see images inside lyx, so I updated from sources to lyx-1.2.1; this version has some improvements, but the end result is mostly the same: the errors must be related to docbook or jade itself. What do you think? Package versions: docbook-dsssl-stylesheets-1.72-34 docbook-utils-0.6.6-67 docbook-xml-website-2.0a2-13 docbook-xsl-stylesheets-1.42-21 docbook_3-3.1-83 docbook_4-4.1-83 docbook-utils-0.6.6-67 jade_dsl-1.2.1-355 openjade-1.3-275 te_latex-1.0.7-285 lyx-1.2.1-1 -- Cheers, Carlos Robinson
