lyx: missing TeX class "aa"

[Thomas Hood]

$ lyx-qt /usr/share/lyx/examples/aa_sample.lyx

result in a dialog reporting:

    Textclass error

    The document uses a missing TeX class "aa".
    LyX will not be able to produce output.

The user gets the same message when he starts lyx and selects
File|New_from_template|aa.lyx

The same problem afflicts IEEEtran, aastex, docbook, and so on.

Running "dpkg-reconfigure lyx-common" does not help.

Running Edit|Reconfigure does not help.

$ dpkg -l \*lyx\*

un lyx-xforms <none> (no description available)

In Help|Extended_Features section 4.4 "A&A paper" it points out
that the .cls file has to be downloaded from an ftp site. The same
goes for the other missing classes, presumably.

Given that aa.lyx is a template shipped in the -common package, I would
expect all the required classes to be included in that package or in
one of the packages upon which it Depends. It turns out that the
required classes aren't packaged at all! It would be much better if
they were. (Please consider this a wish to that effect.)

Finding out why the basic templates don't work requires reading many
long winded help files.

In order to use the basic templates the user has to learn how to
install new classes into LaTeX. This is far from easy for a newbie.

[Edjard Mota (edjard-mota)]

Your're right. IMHO, the examples should be changed from the LyX to use the correct classes which comes in
/usr/share/texmf/tex/latex/.

This seems more a problem of the examples directory being packaged rather than the classes. As far as I know from being a latex user,
such classes (old .sty files) never came with specific classes/styles from .org like IEEE por ACM. We always had to dowwnload them
and set environment variables such as TEXINPUTS.

If one changes the example (aa_example.lyx) from
\textclass aa
to
\textclass article

the example works fine, showing that the template where not based on standard LaTeX classes.

[Edjard Mota (edjard-mota)]

To be more specific, edit the file aa_example.lyx and make the change suggested and you will see that it works.
I have downloaed the latest texmf and have found no such classes. I have also send an emal do lyx-devel list
asking them to try to put only standard LaTeX classes as default templates and teach how to include new ones.

[Edjard Mota (edjard-mota)]

Hi again,

I have an answer from lyx-devel ML, and it seems the problem is really about making LyX templates
associated to TeX classes as I had thought. You can read the dialog below dashed line. I'll try
to help the LyX side and see how it goes.

 I meant the teTex. But if we have to consider other standards then
you're right, that might be confusing.

 Yes, but this has been reported as a bug in some Linux distro, which I
don't agree.

 Could you, or someone, give the directions? I feel like coding and
would be more than pleased to help.

How's dapper on this matter? Does someone have updated information?

[Edjard Mota (edjard-mota)]

Sorry,

I haven't found much time to tacke it as it was suggested from LyX-devel
mailing list
that the best solution would be to re-redisign the way LyX links classes and
templates
to TeX standard classes.

[Eric Lake (ericlake)]

I have installed the LyX package on Dapper and I get the same things described here. I am new to LyX so I thought that it was just me until I saw this post. Thanks for working to resolve this.

[Edjard Mota (edjard-mota)]

Hi Eric,

Yeah, I'm still working on it. But my time is really tight these days.
One thing I think we should have is to separate, in bug track, bugs
which are inherently from Ubuntu development (libraries, etc) from
bugs which are associated to applications. This bug is one example.
This error also raises in any other LyX version for other distros, unless
user set things manualy as I pointed as partialk solution.

[ruchirsaraswat (ruchir-saraswat)]

Hi

I am a newbie to lyx. Just downloaded the same. I get the error as mentioned above when i try to

File|New_from_template|aa.lyx

 Textclass error

    The document uses a missing TeX class "aa".
    LyX will not be able to produce output.

Could somebody please guide me as to how to resolve the same.

Going through the above comments, i saw that i need to install some classes but i could not find how to.

Kindly help out.

Best Regards
Ruchir

[Edjard Mota (edjard-mota)]

Hi,

If you track the messages at https://launchpad.net/malone/bugs/3080 you will
find a solution I proposed to partially solve your problem.
It is not a bug of Ubuntu, but rather a bug of LyX TeX class compatibility.
Try the (manual solution) I proposed and see if it works for you.

As I wrote some time ago, I am trying to find a room im my spare time to
write
a general solution for LyX-devel to which I got some ideas oin how to solve
it.

Hope it helps.

[William Grant (wgrant)]

It has been 9 months since the last comment. Has there been any change in LyX's behaviour?

[Edjard Mota (edjard-mota)]

Unfortunately, no.

The LyX community hasn't done a bit to change this. I tried myself to create
a project
in LyX.org to change that but my time has been very tight since then.

"In a world without fences who needs Gates"

[Fuat Geleri (fuatgeleri)]

Friends,

I think i found a solution in this site
http://www.ece.iit.edu/~jgrad/lyx/

1. Download the cls file you need.
2.
cd /usr/share/texmf/tex/latex/lyx
cp ~/IEEEtran.cls .
mktexlsr .

That is all.
Then open lyx and tools>reconfigure

It fixed the same error that i was getting when i open the IEEEtran template, saying no class found.

Good luck,
Fuat Geleri

[Edjard Mota (edjard-mota)]

Yeah,

This is the same solution I pointed out some time ago. I think LyX guys
have changed the deafult class directory the $HOME or something like that.

We still need to copy a new class template every time it is needed. Thanks
for the site you sent it is really helpful.

[Thomas Hood (jdthood)]

On ubuntu I installed the texlive-publishers package and ran LyX | Tools | Reconfigure.
Now when I File | New from Template | IEEEtran.lyx, I don't get the warning message
I got before.

$ dpkg -L texlive-publishers | grep IEEEtran.cls
/usr/share/texmf-texlive/tex/latex/IEEEtran/IEEEtran.cls

[Vincenzo Ciancia (vincenzo-ml)]

The point seems to be, lyx installs by default templates for classes that are not available, is this correct? If so, shouldn't the bug be solved by providing separate packages for groups of templates, depending on the appropriate texlive packages (maybe only texlive-publishers)?

[Edjard Mota (edjard-mota)]

Yeah,

That's correct.
It seems a possible solution.

Hi,

Is there any news on that one?
I tried to update the cv I wrote a few months ago and I encountered the same problem!

Try opening /usr/share/lyx/examples/fr/simplecv.lyx
and you will get the "Document class not available".

This seems to be link to this bug (?): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=449983

I found the tex class posing the problem with simplecv.layout here:http://www.ctan.org/tex-archive/help/Catalogue/entries/simplecv.html
But I don't even know how to install it!

Any help would be greatly appreciated as I need to update and send my cv soon!!

Thanks,

Seb.

Sebastien: try to install the appropriate texlive package. I can't
access launchpad at the moment (probably due to hardy coming out soon)
but I recall that installing e.g. texlive-publishers solved the issue.
Recall to reconfigure and restart lyx after installation. Alternatively
try to change the document class to "article" in the document's
preferences.

Vincenzo

[Se6 (se6astien)]

Thanks for your answer Vincenzo.
I looked at many texlive packages, none seems to contain the one I am after: simplecv.
Changing the class to "article" is not really a solution, isn't it!
A fix would be to know how to install the CTAN package simplecv.

Seb.

[Vincenzo Ciancia (vincenzo-ml)]

Copy the files in one of the latex directories, e.g. /usr/share/texmf/tex/latex/lyx/, then run texhash, then reconfigure lyx. The first two steps have to be done as root.

[Se6 (se6astien)]

Thanks so much Vincenzo for your help.

I just tried what you said, restarted lyx.. but the document class it is still missing.
In the simplecv.zip from CTAN, there are only: simplecv.dtx simplecv.ins (and testcv.pdf testcv.tex)

Seb.

[Se6 (se6astien)]

For those having the same problem with simplecv.layout, find below a tempory solution to make it work (Thanks to Sven for his help)

1) Download the simplecv package at CTAN (http://www.ctan.org/tex-archive/help/Catalogue/entries/simplecv.html)
2) Extract it and run "tex simplecv.ins". That should produce a simplecv.cls
3) Copy it to somewhere that texhash will find. (I copied it to /usr/share/texmf-texlive/tex/latex/simplecv/)
4) sudo texhash
5) In Lyx, Tools/reconfigure. Close and restart Lyx.

The simplecv class should be available now.

Seb.

[Se6 (se6astien)]

Apparently, the simplecv problem has been addressed a few days ago in the Debian package texlive-extra
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=449983
Any chance that will make it to the Ubuntu repo?

Thanks,

Seb.

[Jean-Baptiste Lallement (jibel)]

Assigning to texlive-extra

For those with the simplecv issue, this is fixed in Intrepid, please install texlive-latex-extra.
For those with the aa issue, it doesn't seem to be fixed.

Dr. Preining,

I will not use MSWin; my OS of choice is Solaris, but that's irrelevant, and it's my fault that you misundestand my comment, so I'll be more clear:

I've struggled with the issue discussed here, with no success. Some posts such as the one by Se6 were somewhat helpful, but simplecv still does not work for me and I don't see any evidence that the posters here are doing anymore than random rituals without any understanding of the underlying mechanics.

I'm dissapointed that I will have to find another tool.

LyX SuX.

[zephirum (zephirum)]

I have a similar problem and it's pretty amazing to find that the bug has lived on for 4 years now.
I'm about to write my thesis and thought Lyx might be the intelligent way of getting to do it; however, if I can't even start the process without getting bogged down my numerous error messages, it's somewhat off-putting.

[Anzenketh (anzenketh)]

Found bug on missing upstream link QA report. Bug for lyx is fixed upstream. Fixed in Intrepid. Added Link to tracker as issue also talks about Issue fixed upstream.

Does this issue occur in Lucid?

$ sudo aptitude install lyx
File | New from Template | aa.lyx results in this dialog:

------------------------
The layout file requested by this document,
aa.layout,
is not usable. This is probably because a LaTeX
class or style file required by it is not
available. See the Customization documentation
for more information.
LyX will not be able to produce output.
--------------------------

$ sudo aptitude install texlive-publishers
Tools | Reconfigure
Restart LyX
File | New from Template | aa.lyx still produces the above message.

So there is still a problem.

[Thomas Hood (jdthood)]

I have the latest packages from oneiric

ii lyx 2.0.0-1~natty1
ii texlive-publishers 2009-10ubuntu1

but the problem (as described in #33) still exists.

[Thomas Hood (jdthood)]

Updated to lyx 2.0.0-1.

"Setting up lyx-common" and "Processing triggers for tex-common" both fail with:

    /usr/sbin/update-language-def: line 779: printf: missing unicode digit for \u

Then starting lyx from an interactive shell produces many instances of

    ../../../../src/frontends/qt4/GuiToolbar.cpp(339): Session settings could not be found!. Defaults are used instead

on the console, which it didn't before; and the faulty behavior as described above (#33) still occurs.

[Thomas Hood (jdthood)]

On a new Ubuntu 12.04 system I did

    sudo apt-get install lyx
    lyx

I clicked File | New_from_template | aa.lyx and Open and once again got an error dialog. The contents of the dialog are a bit different now.

LyX: Document class not available
------------------------------------------------------------
The selected document class
 article (A&A)
requires external files that are not available.
The document class can still be used, but the
document cannot be compiled until the following
prerequisites are installed:
 aa.cls
See section 3.1.2.2 (Class Availability) of the
User's Guide for more information.

Installing texlive-publishers doesn't help. Also, with reference to comment #16, installing texlive-publishers doesn't eliminate the message in the case of IEEEtran.lyx.

[dmbortz (dmbortz-gmail)]

On a new Linux mint 14 system, just starting lyx from the command line gives this error:

../../../../src/frontends/qt4/GuiToolbar.cpp(339): Session settings could not be found!. Defaults are used instead

repeated a large number of times. In googling around, this seems to be an issue with the accessibility extensions in QT. If one removes the qt-at-spi package, this error disappears.

So, whatever the issue is with the A&A class, the GuiToolbar.cpp error seems unrelated.

best,
David
