- a C compiler
+ - an IEEE-754 compliant architecture with rounding to nearest
+ ties to even as default rounding mode (most architectures
+ should work nowadays)
+
- for CoqIDE, the lablgtk development files (version >= 3.0.0),
and the GTK 3.x libraries including gtksourceview3.
+ The IEEE-754 compliance is required by primitive floating-point
+ numbers (Require Import Floats). Common sources of incompatibility
+ are checked at configure time, preventing compilation. In the,
+ unlikely, event an incompatibility remains undetected, using Floats
+ would enable to prove False on this architecture.
+
Note that num and lablgtk should be properly registered with
findlib/ocamlfind as Coq's makefile will use it to locate the
libraries during the build.
