R help - Jul 1999 - Creating shared libraries for dyn.load() in R

Dear R-users,

I am working to install Chong Gu's new gss library on my Linux system
(Redhat 5.1/i386), and have run into the following roadblock:  Dr. Gu's R
code is a front end for a package of Fortran routines called RKPACK.  While
I have no trouble compiling
the individual bits of Fortran code with fort77 in Linux, I don't know how
to link the resulting *.o files into a shared library that R
will read with dyn.load() (I am following the procedure recommended by V&R
in their R Complements to MASS).

I suspect, of course, that the problem is that I don't really understand how
to use ld to produce the shared libraries correctly.  Could anyone indulge a
newbie and offer some advice?  Even a pointer to documentation on how to
build shared libraries would be great.

(Alternatively:  Dr. Gu's Makefile for GKPACK uses "ranlib" to put
the
object code into a *.a file.  Can R be persuaded to use this kind of file?)

Thanks,

Please don't compile RKPACK separately.  Simply use

    R INSTALL -l library gss

in a directory, say $(DIR), which has library and gss as
subdirectories.  The command will automatically compile the gss.so and
the documentation and put them under $(DIR)/library/gss.  Put
$(DIR)/library in your RLIB environment and run library(gss) at the R
prompt, and you are there.
