+
+Building wxGTK or wxMotif completely without configure
+won't ever work, but there is now a new makefile system
+that works without libtool and automake, using only
+configure to create what is needed.
+
+In order to create configure, you need to have the
+GNU autoconf package (version 2.13 or 2.14) installed
+on your system and type run "autoconf" in the base
+directory (or run the autogen.sh script in the same
+directory, which just calls autoconf).

+Call configure with --disable-shared to create a static
+library. Calling "make uninstall" will remove the installed
+library and "make dist" will create a distribution (not
+yet complete).

-a) You have all the newest and greatest GNU tools installed on your system 
-and in the same directory hierachy (e.g. either all tools in /usr or all 
-in /usr/local), these tools are:
-- GNU libtool 1.2e (1.3 doesn't work here)
-- GNU autoconf 2.13 (including autoheader 2.13)
-- GNU automake 1.4 (including aclocal 1.4)
-and possibly but not forcibly
-- GNU make 3.76.1
-- GNU C++ (EGCS)

--> Go to the base directory
--> type: ./autogen.sh
-
-b) You don't know what autos are and have no driver's licence anyway:

--> Go to the testconf directory
--> type: ./apply

-a+b) Then proceed in either case with:
-
--> Choose a directory name that seems fit for building wxWindows, e.g. mybuild
--> Go the base directory
--> type: mkdir mybuild
--> type: cd mybuild
--> type: ../configure --with-gtk

-or type: ../configure --with-wine
--> type make
