-Note that, contrary to LyX 1.0.x, LyX 1.3.x makes great use of C++
-Standard Template Library (STL); this means that gcc users will have
-to install the relevant libstdc++ library to be able to compile this
-version.
+It is _not_ possible to compile LyX with gcc 2.7.x and 2.8.x.
+
+LyX 1.4.x makes great use of C++ Standard Template Library (STL).
+This means that gcc users will have to install the relevant libstdc++
+library to be able to compile this version of LyX. Users of gcc 2.95.x
+will have to install the STLPort version of these libraries as the
+ones that come with gcc 2.95.x are too broken for us to use.
+
+* Qt frontend
+
+LyX has been tested with Qt 3.x, though Qt 2.x may happen to work too.
+The only special point to make is that you must ensure that both LyX
+and the Qt libraries are compiled with the same C++ compiler.
+
+Note that if Qt is using Xft2/fontconfig, you may need to install the
+latex-xft-fonts package (at ftp://ftp.lyx.org/pub/lyx/contrib/) to get
+maths symbols displayed properly. To find out, type:
+
+ ldd `which lyx` | grep fontconfig
+
+at the console. Both RH8 and Debian unstable distributions are known
+to use fontconfig.
+
+If, however, your version of Qt does not use fontconfig, then TeX
+fonts should be added to the font path. 'man xset' is your friend.
