I am trying to use the concrete.sty option with amslatex and amssymb.sty
(which gives names to the symbols in the fonts msam and msbm), whenever
I use one of the names defined in amssymb I get a message like this:
! \textfont 7 is undefined (character ?).
l.14 If $f(s)=\varnothing$
we say that the state
\varnothing is defined in amssymb.sty as:
\newsymbol\varnothing 203F
Reading concrete.doc it looks as though I need to add the msam/msbm fonts to
the euler math group (?), but I'm not sure how to do this.
Ideas anyone?
Martin.

Unfortunately, you are giving not enough information to see what is
going on here, so I have to make a good guess.
I suppose that the above error occurs after switching to the `euler'
math version. If this is indeed the problem, it comes from the AMS
suymbol fonts not available in this version. To add them to the `euler'
*version* you have to write down a few \define@mathgroup commands. As
a guideline, you might want to look into amsfonts.sty where you find
\define@mathgroup\mv@normal\msa@group{msa}{m}{n}
\define@mathgroup\mv@normal\msb@group{msb}{m}{n}
\define@mathgroup\mv@bold\msa@group{msa}{m}{n}
\define@mathgroup\mv@bold\msb@group{msb}{m}{n}
This defines the math groups for the two groups of math symbol fonts
in the `normal' and `bold' versions. For the `euler' version it is
probably sufficient to write
\define@mathgroup\mv@euler\msa@group{msa}{m}{n}
\define@mathgroup\mv@euler\msb@group{msb}{m}{n}
I haven't checked this out, so I might have overlooked a detail :-),
but the above two lines are certainly necessary.
Hope that helps.
