LyX ⇒ Lyx fails with cannot find .sty file, should be using a .cls

[hedgeboar]

I've added a .cls file called mechthesis.cls to my MiKTeX istallation (at least I think I have), and created a .layout file for LyX. This works fine on my office PC, running LyX 1.6.7 on windows XP x64. However, when I try this on my laptop running Windows 7 I get the message:
"LaTeX Error: File 'mechthesis.sty' not found."
So it seems it's looking for a .sty instaed of the .cls I've supplied. I've also tried this on another machine running kubuntu lucid with the same results....

I've tried putting mechthesis.cls in C:\Program Files (x86)\MiKTeX 2.8\tex\latex\base as well as a folder in a directory I have added to MiKTeX using the settings GUI. I have updated the FNDB many times, and done 'reconfigure' in LyX many times.

Any Ideas? How can I check to see if mechtheis.cls is recognised by MiKTex? my mechthesis.layout is below.

I really have no experience with creating LyX layout files, but \usepackage{xxx} is only used in LaTeX for loading packages (i.e., .sty files), not for document classes. Document classes are chosen with the \documentclass command; in your case, \documentclass{mechthesis}. So if mechthesis is a .cls file, not a .sty file, then it makes no sense to have this part:

Code: Select all

Preamble
   \usepackage{mechthesis}
EndPreamble

in your .layout file. I'd start just by removing that. If that doesn't do it, I'm not sure I can be of much help, though a quick look at this page also makes me think that perhaps you shouldn't have ",book" in the line:

Code: Select all

#  \DeclareLaTeXClass[mechthesis,book]{mechthesis}

but I'm not sure about that.

I wouldn't go into technical part, but just a general reminder: when you manually add anything new to your LaTeX installation, don't forget to refresh the database:

Code: Select all

texhash

Apart from that, you may have to reconfigure LyX too: Tools > Reconfigure.

Thanks frabjous, removing the \usepackage did fix that problem..... Although that seems odd as it works fine on my office PC like that.
However, now it is giving font errors for greek characters in the text -- it's fine if I put them in as an inline formula, but if they are directly in the text it fails and gives this message:

Code: Select all

Errors:
Font LGR/cmr/m/n/10.95=grmn1095 at 10.95pt not loadable: Metric (TFM) file no

Description:
 ...y an elevation angle, $\Phi$\textgreek{F}
                                                  ,
I wasn't able to read the size data for this font,
so I will ignore the font specification.
[Wizards can fix TFM files using TFtoPL/PLtoTF.]
You might try inserting a different font spec;
e.g., type `I\font<same font id>=<substitute font name>'.
