To build Openbox from CVS you need:
A C Compiler (GNU GCC 3.2+ suggested)
-GNU Gettext
+GNU Gettext 0.12.1
GNU Autoconf 2.50+
GNU Automake 1.7+
GNU Libtool
-GNU Bison 1.875+
-GNU Flex
Xft2 library/headers (devel package) (http://www.fontconfig.org)
Xlib library/headers (devel package)
Pkg-Config
Optionally, if you want to build the configuration tool (this is recommended):
GTK+ 2.0+ library/headers (devel package) (http://www.gtk.org)
-libglade 2.0+ library/headers (devel package) (http://www.gnome.org)
I recommend the latest version of all these packages.
+----
+In debian unstable, you want these packages:
+gcc
+gettext
+automake1.7
+autoconf
+libtool
+libxft2-dev
+pkg-config
+libglib2.0-dev
+libxml2-dev
+
+optionally:
+libgtk2.0-dev
+
+tip: run "update-alternatives --config automake" and select automake1.7 before
+ running ./configure
+
