[Rd] Installing RSPython with R 1.3.0

[Gregory R. Warnes]

To get RSPython installed on my debian test box, I had to make a couple
of changes not listed in
ftp://www.omegahat.org/pub/Omega/RSPython/FAQ.html 

1) I had to change $R_HOME/src/modules/X11 :

$(R_X11_la): $(R_X11_la_OBJECTS) $(R_X11_la_DEPENDENCIES)
        $(SHLIB_LINK) -o $@ $(R_X11_la_LDFLAGS) $(R_X11_la_OBJECTS)
$(R_X11_la_LIBADD) $(LIBS) 

to

$(R_X11_la): $(R_X11_la_OBJECTS) $(R_X11_la_DEPENDENCIES)
        $(SHLIB_LINK) -o $@ $(R_X11_la_LDFLAGS) $(R_X11_la_OBJECTS)
$(R_X11_la_LIBADD) $(LIBS) -L$(R_HOME)/bin -lR

2) I had the same link problem with ctest, so I changed

PKG_LIBS =  -lg2c -lm -L/usr/lib/gcc-lib/i386-linux/2.95.4 -lm

to

PKG_LIBS =  -lg2c -lm -L/usr/lib/gcc-lib/i386-linux/2.95.4 -lm
-L$(R_HOME)/bin -lR


3)  Will all libraries that get loaded into R inside of python require
this?


If I try to load other 'recommended' packages that include C code I get
dyn.load erros, EG:

>>> RS.call("library","splines")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library
"/usr/local/lib/R/library/splines/libs/splines.so":
  /usr/local/lib/R/library/splines/libs/splines.so: undefined symbol:
R_NaN
Error in function (package, help, lib.loc = .lib.loc, character.only =
FALSE,  :
        .First.lib failed
In the local error handler
In the local error handler
Error in if (!is.numeric(name) || name != (pos <- as.integer(name))) { :
        missing value where logical needed
