Hi Petr,

I think the way that has more chances to succeed to build wxMSW is to 
use the autotools instead of the makefile. You'll need autoconf, 
automake, pkgconfig (as you mention below), of course cairo, glib and 
pango (available as win32 binaries and headers on ftp.gtk.org), and 
possibily a couple of other tools/libraries (I remember having to 
install zlib).

Once you have built wxMSW, you'll get wx-config. You should install 
pkg-config too to get cairo and pango flags.

Did you mean "comment" or "uncomment" ?

Of course !

You not only need dlls but also .lib files that correspond to symbol 
lists or something like that.

I'll try, if I find some time...
