Requirements

• Glib/Gtk+: Glib/Gtk+ is the widget set (written in C) Terraform is built on. You need a Gtk+ release of the 1.2.x series, preferrably the newest one available. Due to some semi-serious bugs which break terraform, Gtk+ 1.2.4 is not supported.

• Gtk--: Gtk-- is the wrapper around Gtk+ which provides C++ language bindings. It fully supports all native C++ goodies and is (IMHO) quite nice (if you like the features C++ gives you). You need Gtk-- 1.1.9 or newer.

• An ANSI compliant C++ compiler: I have personally tested that gcc (as of 2.8.1, with 2.95.x being preferred) support the C++ features Gtk-- and terraform require. If you manage to get terraform to work with any newer versions of these compilers, or even with a non-GNU compiler, please let me know.

Terraform can make use of the following libraries/programs, if they are installed on your system. You can build and use the application without these packages, but some functionality will be missing:

• Imlib: used to read TIFF and PNG files as well reading and displaying the terraform logo in the about dialog.

• OpenGL/Mesa: used for a preview rendering. Currently of alpha quality. If you wish to use OpenGL, you must have Mesa 3.0, GtkGLArea 1.2.1 and GtkGLArea-- 1.1.1.

• POVRay: can be used to photorealistically render the height field you're editing in terraform at the click of a button.

The following platforms are known to have worked for terraform. Should you be on a platform similar to the ones listed below, your chances of terring terraform to work are pretty good.

• Linux ix86 Debian 2.1
• Linux ix68 Mandrake 6.0 (egcs-2.91.66, gcc-2.95)
• Linux ix68 Mandrake 6.1 (gcc-2.95)
• Linux ix68 RedHat 5.2 (egcs 2.91.57)
• Linux ix68 RedHat 6.0 (gcc 2.8.1, egcs-2.91.66)
• Linux ix68 Vine 5.2 (egcs-2.91.57), a RedHat based Japanese distribution
• Solaris Sparc 2.6 (egcs 2.91.66)
• Solaris Sparc 2.7 (gcc 2.8.1)
