R help - Nov 1998 - loading fortran with Redhat 5.1

Hi All,

I'm running R 0.63 on Redhat 5.1 and when I attempt
to load a fortran routine I get:
> dyn.load("/home/royle/Rstuff/varna.o")
Error in dyn.load(x) : unable to load shared library
"/home/royle/Rstuff/varna.o"


this function varna.o was compiled with:

 gcc -c varna.f

with no errors or warnings.

Does anyone have any thoughts on this?

Thanks! (and thanks to everyone who replied to my previous query
on an attach() surrogate)

Contrary to S[-plus], dyn.load(.) in R  only allows the dynamic loading
of shared libraries.

Insofar, dyn.load(.) maybe should have been called
	 dyn.load.shared()  instead.

You have to add (to the above)

	R SHLIB varna.o -o varna.so

or even do this at once:

	R SHLIB varna.c


and then

	dyn.load("....../varna.so")

----
In addition to  
	help(dyn.load),
	help(SHLIB),
see also in  RHOME/demos/dynload  and look at the Makefile.
