Bug 1687: request for help. :-)
Hi, I am lost. :-) The bug is: http://bugzilla.lyx.org/show_bug.cgi?id=1687 In short, a user running a 64 bit plataform and lyx-1.3.4 has problems exporting any docbook document in any format. LyX always crashes, and the bug report is here: http://bugzilla.lyx.org/attachment.cgi?id=597&action=view What I find strange is the frame #5: #5 0x00456f50 in Buffer::makeDocBookFile (this=0xb38fc0, [EMAIL PROTECTED], nice=true, only_body=false) at buffer.C:2945 fname is supposed to be a reference to a constant string, yet it is null. The first code in makeDocBookFile that checks to see if the ostream was succefuly created does not fail. Then some of the values above are completly bogus, the depth for example. Clearly this does not happen on i368, or else I would have noticed, and I don't have also any x86_64 to test. -- José Abílio

You could ask someone with a 64bit box for help! ;-P Sorry, I have my nasty day again, JosÃ. At our institute we ordered a couple of Athlon64s which should arrive in a few weeks if not next year (well, you know about university administration, no?) If the bug is still open at that time I'll give it a try. Ciao /Andreas

What you could try to test for: - is the compiler up to date? - Does disabling optimization help? - can valgrind run on x86_64? JMarc

José, Just for info: I use 1.3.x all the time on a 64bit Alpha machine and have never had the problem described in this bug report. -- Angus

Not easily. What would I need to install? However, I note that the guy said that exporting to DVI, PDF also crashed lyx. That doesn't happen here. Incidentally, trying to export an empty document as a DVI file results in a warning dialog: Alert The operation resulted in an empty file Dismiss What happens if you do this with docbook? -- Angus

What would I need to install? Don't ask! ;-) If you just want to see the XML/SGML files you could try to create a dummy 'sgmltools' script in your path and reconfigure. If LyX is fooled, it will offer Docbook classes after a restart. Export to XML / SGML does not need sgmltools, that's only for further processing. A minimal Docbook document should have a title, the highest sectioning command (chapter for Docbook (book) and section for Docbook (article)) and a non empty paragraph after that. If an "xmllint --valid mydb.xml" does not output only errormessages but also the document content, then the document was well formed. Don't expect validity (yet :-)). Ciao /Andreas

What would I need to install? Put somewhere in your path some dummy script with execution permissions called sgmltools or db2dvi. When I want to test lyx in some machine but not install the docbook tools this is exactly what I do. That you will not be able to see the resulting dvi or pdf. But that is not the problem here. > However, I note that the guy said that exporting to DVI, PDF also crashed > lyx. That doesn't happen here. But from docbook, not from latex. That happens because the first export fails, I think. > Incidentally, trying to export an empty document as a DVI file results in a > warning dialog: > > Alert > The operation resulted in > an empty file > Dismiss > > What happens if you do this with docbook? It looks like the same, this is strange. Both for 1.3 and 1.4, so this means that no file is exported... File error. The specified file '/tmp/lyx_tmpdir5505ZkAmOy/lyx_tmpbuf0/newfile1.dvi' does not exist. KDVI already tried to add the ending '.dvi'. > -- > Angus -- José Abílio Matos LyX and docbook a perfect match. :-)

Ok. I can confirm that a "DocBook article (SGML)" document exports to DocBook perfectly on my LinuxAlpha machine. No problems with with the XForms or the Qt versions of LyX 1.3.x cvs. -- Angus
