The Utrecht Haskell Compiler (UHC)
==================================

This is the top directory of the UHC source tree, for the compiler and
the tools and libraries required to build UHC. UHC grew out of the
Essential Haskell Compiler (EHC) project, but the name EHC will
gradually not be used overtime. The web entry point for information
about UHC is:

	http://www.cs.uu.nl/wiki/UHC/WebHome

Here the elaborate instructions for getting started and downloading can
be found.


Platforms
===================

UHC currently compiles/runs on MacOSX (10.11) with GHC 7.10.
Compiling on other Unix platforms in general does not give problems,
but is somewhat unpredictable due the great variation in combinations.


Installation
============

Support for GCC 4.9 is currently broken. Either use an older version of GCC or LLVM/clang. 
You can set the C compiler using the "--with-gcc=PATH_TO_C_COMPILER" configure option, eg
"./configure --with-gcc=/usr/bin/clang". See issue #32 for details.

The short version for installing uhc (from either binary or
source distribution) is:

	./configure
	make				# optional
	make install		# may require admin permission

More detailed information currently still labeled with EHC can be found
here:

Experimentation (optional)
==========================

The following ./configure invocations lead to buildable compilers
20140331:
	./configure --with-aspects="base"							# only ASTs, parser, pretty printing
	./configure --with-aspects="base hmtyinfer noHmTyRuler"		# + HM type system (without use of ruler system)
	./configure --with-aspects="base hmtyast"					# only Ty infrastructure without its use
