[R] R and Fortran

[Derrick Lee]

Dear Fellow R-Users,

I am having some difficulties loading a Fortran subroutine into R and 
wondering if anyone could lend me some insight to this problem. When I 
load some simpler Fortran codes into R, it loads fine, but when I load 
more complex codes I get the following error:

        Error in dyn.load(x, as.logical(local), as.logical(now)) :
                unable to load shared library 
"/nfs/home/grad/d.lee/Testing/chol.o":
          ld.so.1: R: fatal: relocation error: file 
/nfs/home/grad/d.lee/Testing/chol.o: symbol s_wsle: referenced symbol 
not found

 From what I have gathered, it appears to be a problem when with linking 
the library to the Fortran system library, but I am unsure how to deal 
with this. As well, I was wondering why I am unsuccessful loading those 
same "successful" codes when I go from a 32-bit machine to a 64-bit 
machine, why does that cause such a big issue? The current 32-bit 
machine that runs R is:

platform sparc-sun-solaris2.8
arch     sparc              
os       solaris2.8         
system   sparc, solaris2.8  
status                      
major    2                  
minor    0.1                
year     2004               
month    11                 
day      15                 
language R

Any help to these queries would be very much appreciated. Cheers.


Sincerely

 - Derrick
