Installing PolyOp
                        =================

Note: In case of problem, please read this INSTALL file carefully before reporting a bug.

The installation of PolyOp is trivial and immediate (see end of this file).
However, the installation of the other libraries (especially PPL), although not difficult, will take more time.


************************************************************
INSTALL OCAML
************************************************************
(the version used to develop PolyOp is 3.11.2)

	./configure -prefix /usr

	make world

	make bootstrap

	make opt

	make opt.opt

	sudo make install

OCaml should be installed in:
        binaries.................. /usr/bin        
        standard library.......... /usr/lib/ocaml  
        manual pages.............. /usr/man (with extension .1)



************************************************************
INSTALL Extlib
*************************************************************
Create directory, e.g., "toto".

ocaml install.ml
	-> both
	-> toto/
	-> 

Copy
	toto/*
to 
	/usr/lib/ocaml/extlib/

Add /usr/lib/ocaml/extlib/ to the path:
	export PATH=$PATH:/usr/lib/ocaml/extlib/


************************************************************
INSTALL g++
************************************************************
Using the package manager


************************************************************
INSTALL m4
************************************************************
Using the package manager


************************************************************
INSTALL GMP
************************************************************
(
	Message during the PPL installation
	*** MEMORY EXHAUSTION MAY RESULT IN ABRUPT TERMINATION.
	*** This is OK, if you do not plan to use the bounded memory capabilities
	*** offered by the PPL.  Otherwise, if you are using GCC or the Intel C/C++
	*** compiler, please make sure you use a version of GMP compiled with the
	*** `-fexceptions' compiler option.
	*** To build such a version, you can configure GMP as follows:
	*** CPPFLAGS=-fexceptions ./configure --enable-cxx --prefix=/usr

	« When compiling the GMP library, do not forget to enable the C++ interface:
	add --enable-cxx to the configuration options. »
)

	CPPFLAGS=-fexceptions ./configure --enable-cxx --prefix=/usr

	make
	make check		<= VERY IMPORTANT!!

	sudo make install

Libraries have been installed in:                                                 
	/usr/lib

(
	If you ever happen to want to link against installed libraries
	in a given directory, LIBDIR, you must either use libtool, and
	specify the full pathname of the library, or use the `-LLIBDIR'
	flag during linking and do at least one of the following:      
	   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable  
	     during execution                                          
	   - add LIBDIR to the `LD_RUN_PATH' environment variable      
	     during linking                                            
	   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag              
	   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

	See any operating system documentation about shared libraries for
	more information, such as the ld(1) and ld.so(8) manual pages.   
)


************************************************************
INSTALL MPFR
************************************************************
	./configure --prefix=/usr --with-gmp-lib=/usr/lib --with-gmp-include=/usr/include
	
     make

5. To check the built library (runs the test files), type:
     make check

6. To install it (default "/usr/local" | see "--prefix" option), type:
	sudo make install

Libraries have been installed in:

************************************************************
INSTALL MLGMP
************************************************************
http://www-verimag.imag.fr/~monniaux/programmes.html.en

Edit make file :
- GMP_LIBDIR=/usr/lib
- GMP_INCLUDES= -I=/usr/include


	make

************************************************************
INSTALL PPL
************************************************************

	./configure --prefix=/usr --with-libgmp-prefix=/usr --with-libgmpxx-prefix=/usr --with-mlgmp=/usr/lib/ocaml/gmp

	make

	make check (optional and very very long, several hours at leasat)
OR (to check linking with ocaml)
	cd interfaces
	make check

	make install


************************************************************
(finally) INSTALL PolyOp
************************************************************
Just type "make"
Easy, isn't it?
