Read instructions below to install the required libraries or get them
compiled (gcc 2.95) at ftp-fourier.ujf-grenoble.fr/xcas/devel
Then run ./configure, and cd src make, then sh mkstat, then edit
xcas.fl and remove the Input_tab input, rename the hidden input_old to
input and remove the hidden declaration, then fluid -c xcas.fl,
then make again and sh mkxstat will build xcas
To move xcas, use the Finder or use cp but then run fltk-config --post xcas
to make xcas visible from the finder

fltk (version 1.2.x): fltk on MacOSX will compile without the need for X11
%make
%sudo make install

flvw: (use flvw-20000224.tgz)
%./configure
%emacs makeinclude
Change the following (line 52):

LIBS   =       -lflvw  -lX11 -lXext -rdynamic -lm -ldl
LDFLAGS        =       -g -O2 -L/usr/X11R6/lib -L../lib

into:

LDLIBS = -framework Carbon -framework ApplicationServices -lsupc++
GLDLIBS = -framework AGL -framework OpenGL
LDFLAGS  = $(LDLIBS) $(GLDLIBS) -lfltk_gl -lfltk -lm ../lib/libflvw.a
LIBNAME = libflvw
LIBRARY = ../lib/libflvw
#LIBS   =       -lflvw  -lX11 -lXext -rdynamic -lm -ldl
#LDFLAGS        =       -g -O2 -L/usr/X11R6/lib -L../lib
---

%emacs FL/Flv_List.H
Comment the line 52:
//#define fl_inactive inactive

%make
%sudo make install

If you want to play with the executable created in the test directory you will have to run on each executable:
 /Developer/Tools/Rez -t APPL /usr/local/include/FL/mac.r -o test/exename

Replace exename with either exercise, testedit, testlist, basiclist, testtable, testtable2

-iconv library: (ftp://ftp.gnu.org/gnu/libiconv/libiconv-1.8.tar.gz)
Get it all done: http://www.hmug.org/pub/MacOS_X/BSD/Libraries/System/libiconv/libiconv-1.8-1-osx2.tar.gz

%./configure
%make
%sudo make install

-gettext (http://mirrors.kernel.org/gnu/gettext/). Make you are using gettext version 0.11.2, for some reason I can't get
giac to work properly with version 0.11.5. I suspect a problem in 0.11.5 rather than in giac
Either get it all done: http://www.hmug.org/pub/MacOS_X/BSD/Development/Tools/gettext/gettext-0.11.2-1-osx.tar.gz

./configure --with-included-gettext --without-libintl-prefix --enable-static

%./configure
%emacs config.h
  add #define __USER_LABEL_PREFIX__ _
%make

-giac:
%./configure --enable-dl=no

%emacs src/Makefile
