By the way, this is solved by running qt4config

It seems that this is due to wchar.h missing on your hard drive. When i look for it ("locate wchar.h") on mine, it seems to be:
/usr/include/wchar.h
and
/usr/include/bits/wchar.h

Asking rpm for which files have provided them:
"rpm -q --whatprovides /usr/include/wchar.h"
the returned file is:
glibc-devel-2.4-8mdv2007.1
(OK, I reckon I have a mix of 2007.1 and 2007.0 on this computer).

Have you installed glibc-devel package ? It is the most basic devel package to install if you want to compile a program. If not, then I wonder if you will not have plenty of other errors later. You need to install devel packages for every library that LyX will use in order to compile it. A decent install should always have devel packages for glibc, gtk, X, qt, glib, stdc++ and a few other installed.

Best regards,

Olivier

PS: actually, wchar_t may be defined in stddef.h, provided also by glibc-devel
