RXLisp

[Jan de Leeuw]

I was obviously fascinated by Duncan's earlier message on RXLisp.

I managed to build a working version of RXLisp for OS X, by some
unabashed and rather uninformed hacking. I compiled XLISP-STAT using
the gcc flags -fno-common  and --no-cpp-precomp (not sure if they
are necessary or not, they are part of an older hack). I "make
libxlisp.so", using Duncan's replacement for the three XLS files
(I am not sure if these are necessary with my build strategy, probably
not).  I do not really make libxlisp.so, because there is no -shared  
flag for
the static linker in OS X. I just leave the XLS directory with a broken  
link
and a lot of foo.o files.

Then I do , in the appropriate place,

R CMD INSTALL --configure-args='--with-build-dll' RXLisp

but the final link of this  is

gcc -bundle -bundle_loader /usr/local/lib/R/bin/R.bin  -o RXLisp.so \
	Converters.o RXLisp.o \
          -L/Users/deleeuw/MyStuff/Developer/xlispstat-3-52-18 -lxlisp

This breaks, of course, there is no libxlisp. I then move to RXLisp/src  
and do

gcc -bundle -bundle_loader /usr/local/lib/R/bin/R.bin  -o RXLisp.so \
	Converters.o RXLisp.o \
	$XLISP_SRC_DIR/*.o -L/usr/X11R6/lib -lX11 -L/sw/lib -ldl

i.e. I link all the foo.o files Duncan puts in libxlisp.so. Then once  
more

R CMD INSTALL --configure-args='--with-build-dll' RXLisp

which puts everything in the R hierarchy. Now I can do

RXLisp can of course only do subr's (i.e. functions defined
in compiled C code in XLS), and it does not know about
XLS objects, graphics, arrays, vectors, etc. I am not sure
if my version, which does not use the libxlisp.so shared
lib at all, can do all that Duncan's version can. I will put
RXLisp as a binary package on http://gifi.stat.ucla.edu/pub
