-* The GTK+ 2 case

-wxGTK has support for the new version 2.0.X of GTK+ since version 2.4.0.
-This means that wxGTK apps can now make use Unicode as the underlying encoding
-for all text operations. This is a very fundamental change and will need time
-to stabilize, so be careful. Anyways, after installing a recent version of GTK+
-2.0, do this
-
-> ./configure --with-gtk --enable-gtk2 --enable-unicode
-> make
-> su <type root password>
-> make install
-> ldconfig
-> exit
-
-If you are adventurous, you can install the FcConfig 2.0 package
-and the Pango library from CVS (or a very recent snapshot from
-the upcoming 1.2 series) and set do "export GDK_USE_XFT=1" so
-that the display as well as the printing code will use render
-using the same FreeType code even for Far Eastern encodings.

 
 

-Expect problems.
+Note that by default, GTK+ 2.X is used. GTK+ 1.2 can be specified
+with --with-gtk=1.

+* Building wxGTK on Cygwin
+--------------------------
+
+The normal build instructions should work fine on Cygwin. The one difference
+with Cygwin is that when using the "--enable-shared" configure option (which
+is the default) the API is exported explicitly using __declspec(dllexport)
+rather than all global symbols being available.
+
+This shouldn't make a difference using the library and should be a little
+more efficient. However if an export attribute has been missed somewhere you
+will see linking errors. If this happens then you can work around the
+problem by setting LDFLAGS=-Wl,--export-all-symbols. Please also let us know
+about it on the wx-dev mailing list.
