Hi,
I just upgraded my machine from Redhat 9 to Fedora Core 4. Since the
upgrade (which I saw inclued a tetex upgrade), LyX 1.3.6 does not
recognize any Tex document classes: 'The document uses a missing TeX
class "article". LyX will not be able to produce output'. I found
previous messages on the archives with similar troubles and tried
those solutions (in particular
http://www.mail-archive.com/lyx-users@lists.lyx.org/msg40759.html and
http://www.mail-archive.com/lyx-users@lists.lyx.org/msg39463.html ),
but they did not work for me. My TeX classes are present: they are
found by LyX in View->TeX Information ->LaTeX classes ->article.cls
(for example), and they are also found by doing
$ kpsewhich tex article.cls
/usr/share/texmf/tex/latex/base/article.cls
I have run texhash and LyX->Edit->Reconfigure, deleted my ~/.lyx
directory and restarted, even reinstalled LyX just to be sure, to no
avail.
When I do LyX->Help->LaTeX Configuration, Section 1 says that "The
LaTeX version that LyX will use is: ???" And every item in the
document is followed by a "Found: ???". So LyX can't find LaTeX just
because I upgraded my OS? To be fair, I never bothered to check what
this file said before the upgrade, as everything worked fine.
I am now out of ideas, and any you have would be much appreciated.
Reinstalling teTeX seems a bit extreme, since everything is here already.
thanks,
Derek Lamb

ok, I asked someone to make sure I was doing that correctly (I use LyX
so I don't have to use LaTex more than necessary), and I got this:
$ latex code-comparison.tex
This is pdfeTeXk, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)
%&-line parsing enabled.
kpathsea: Running mktexfmt latex.fmt
fmtutil: format directory `/web2c' is not writable.
I can't find the format file `latex.fmt'!
So why did the new distro create a /web2c anyway? That sure wasn't
there before. And I shouldn't have to have write permission to a
root-mounted directory just to run LaTeX (though I suppose that I
could). So
$ locate latex.fmt
/usr/share/texmf/web2c/platex.fmt
/usr/share/texmf-var/web2c/pdflatex.fmt
/usr/share/texmf-var/web2c/latex.fmt
shows that these files exist somewhere at least, but not in /web2c.
There is a /web2c/tex.fmt, but no /web2c/latex.fmt
When I make /web2c writable and rerun the above command, a bunch of text
flies by, ending with:
"No pages of output.
Transcript written on latex.log.' instead of a filename.
I can't find the format file `latex.fmt'! "
I checked /web2c/latex.log and it doesn't appear to have anything useful
in it (but if you want it ask me), it ends with a bunch of TeX memory
diagnostics and the phrase "No pages of output."
