Compilation under unix and MacOs 10.2 or cygwin  with g++ 
--------------------------------------------------------
please read all before began and read READ_ARPACK for eigen value tools

for compilation  under window or MacOs 
with codewarrior compiler  see the README_CW.


The makefile is now parameter with the shell variable HOSTTYPE.
All the local compilation variable is now defined in  file
src/Makefile-$HOSTTYPE

the list of Makefile-*
Makefile-Debian              # with    arpack, install the debian package arpak and arpack++
Makefile-hp9000s700          # without arpack on hpux with g++
Makefile-i386                # without arpack on i386 with g++
Makefile-linux               # with    arpack    on linux with g++
Makefile-linux-arpack        # with    arpack    on linux with g++
Makefile-linux-noarpack      # without arpack    on linux with g++
Makefile-macintosh           # with    arpack on MacOsX 10.2  with g++
Makefile-macintosh-noarpack  # without arpack on MacOsX 10.2  with g++
Makefile-macintosh-arpack    # with arpack  on MacOsX 10.2 with g++

Suppose you HOSTTYPE are xxx begin by a version without arpack 

1) cp src/Makefile-... src/Makefile-xxx 
2) edit src/Makefile-xxx 
and  change if necessary the variables 

LIBLOCAL = -ldl   # for dlopen (see man dlopen and or load.cpp)
LIBX11= -L/usr/X11R6/lib -lX11 -lm 
INCLUDEX11 = /usr/X11R6/include
CXX=g++      #C++ compiler 
BIN_DIR=$(HOME)/bin-$(HOSTTYPE)

In this case:

- the following file must be exist
  /usr/X11R6/lib/libX11.a       see  the variable LIBX11
  /usr/X11R6/include/X11/Xlib.h         see  the variable INCLUDEX11

- the shell command exist 
  >  g++ -v 
     Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
     Thread model: posix
     gcc version 3.3 20030304 (Apple Computer, Inc. build 1435)
  The version must  be 2.95.2,  2.95.3 our 3.1 or better

- the BIN_DIR variable is the place to install (copy) the software.


 
if you need the eigen-value computation
install the arpack and arpack++ library see README_ARPACK

To defined $HOSTTYPE to linux  under sh shell
> export HOSTTYPE=linux 
or add HOSTTYPE=linux at the end of the make command, like
> make all  HOSTTYPE=linux


The variable defined in this file src/Makefile-$HOSTTYPE are :
OOPTFLAGS= -O  # compilation with optimization
GOPTFLAGS= -g  # compilation with debugging 
# FLAGS for optimisated version 
OFFFLAGS= -DDRAWING -DLONG_LONG  -DNCHECKPTR 
#  flags for debug version  
GFFFLAGS= -DDRAWING -DLONG_LONG -DCHECK_KN #-DWITHCHECK
BIN_DIR=$(HOME)/bin-$(HOSTTYPE)   #install dir
COMPILE_DIR=c-$(HOSTTYPE)        #compile dir.

Freefem++ with eigen value
EIGEN= eigenvalue.o  # to compile the target eigenvalue.o 
LIBARPACK=  (the arparck fortran  library)
LIBF77=   (the fortan library)
INCARPACKPP = -DEIGENVALUE -I(arpack++ include directory)

Freefem++ without eigen value 
EIGEN=
LIBARPACK= 
LIBF77=
INCARPACKPP=



So to compile create the file  src/Makefile-$HOSTTYPE
to add /or change the compiler, change the 
location of X11R6 include and library.



to compile optimized version (compilation take more than 30m)
> make all 
this create file 
 $(COMPILE_DIR)/FreeFem++
 $(COMPILE_DIR)/FreeFem++-nw


or (for the debug version)
> make all-g 
this create file 
 $(COMPILE_DIR)-g/FreeFem++
 $(COMPILE_DIR)-g/FreeFem++-nw

>make mpi 
to make parallele version , defined correctly the MPI variable

>make gl
to make the MacOS OpenGL optimize  version for FreeFem++ CoCoa application

>make glx
to make the OpenGL optimize version for FreeFem++  application with X11 window

>make mpi-g 
to make parallele version , defined correctly the MPI variable

>make gl-g
to make the MacOS OpenGL version for FreeFem++ CoCoa application

>make glx-g
to make the OpenGL version for FreeFem++  application with X11 window

the list of exec file can be 

optimze version:

 $(COMPILE_DIR)/FreeFem++             application with X11 graphix
 $(COMPILE_DIR)/FreeFem++-nw          application without graphic window
 $(COMPILE_DIR)/FreeFem++-glx         application with X11 and OpenGL
 $(COMPILE_DIR)/FreeFem++-agl         cocoa application for macos with apple OpenGL
 $(COMPILE_DIR)/FreeFem++-mpi         mpi application without window graphic
 $(COMPILE_DIR)/FreeFem++-x11         application with X11 graphic

same application with debug version: 

 $(COMPILE_DIR)-g/FreeFem++
 $(COMPILE_DIR)-g/FreeFem++-nw
 $(COMPILE_DIR)-g/FreeFem++-glx
 $(COMPILE_DIR)-g/FreeFem++-agl
 $(COMPILE_DIR)-g/FreeFem++-mpi
 $(COMPILE_DIR)-g/FreeFem++-x11



> make install 
to install all the  current version in directory  $(BIN_DIR)
(this Makefile variable is define in src/Makefile-$HOSTTYPE) 
remark: the directory must exist before install.

The install file can be:

 FreeFem++          #  optimized X11 version
 FreeFem++-g        #  debug X11 version
 FreeFem++-nw       #  optimized postscript  version 
 FreeFem++-nw-g     #  debug     postscript  version 
 FreeFem++-mpi      #  optimized mpi version 
 FreeFem++-mpi-g    #  debug mpi version 
 FreeFem++-glx      #  optimized OpenGl with X11  version 
 FreeFem++-glx-g    #  debug OpenGl with X11 version 
 /Applications/FreeFem++.app  # Drag and Drop CoCoa MacOs Application with 
 FreeFem++-CoCoa    #  MacOS Shell script  for MacOS  OpenGL version  (MacOS 10.2 or better)
                    #  use  /Applications/FreeFem++.app


--tested  under linux or MacOs/Darwin with the compilers 
g++  version 2.95.2, 2.95.3, 3.01 3.1 3.3

it take 15 mn to compile all all-g  on my PowerBook G4 666Mhz 256MB,
and it take more than 1hour under linux.

Under window or MacOs the soft was precompile

All the Examples are in the  two directories
examples++ and examples++-tutorial the suffixe is .edp 
 (equations aux derivees partielles in french)

to test all the exemple under unix: 

cd examples++; ../c-$HOSTTYPE/FreeFem++  all.edp
cd examples++-tutorial; ../c-$HOSTTYPE/FreeFem++   all.edp


Under MacOS 10.2 under terminal application:
1) edit src/Makefile-macintosh to set your
BIN_DIR=$(HOME)/bin/$(MACHTYPE)-$(VENDOR)-$(OSTYPE)
for example to (if you have root access)
BIN_DIR=/usr/local/bin 
remark the BIN_DIR must be in your PATH shell variable
2) compile with:
make all all-g gl-g gl
3) install:
make install
4) to run 
FreeFem-CoCoa examples++-tutorial/all.edp


Warning on MacOSX, some link problem occures because the  RTTI and template
with the apple version c++ (version 2.95.2)  and
this working now  with new g++3 compiler (default compiler in MacOs 10.2) 
and also with  g++-3.3 compiler
