R devel - Dec 2004 - 64-bit R failed to compile some packages (PR#7440)

Full_Name: Vincent Yau
Version: 2.0.1
OS: Solaris SPARC 9
Submission from: (NULL) (137.53.23.145)


We have recently upgraded to using 64-bit R.  Was trying to install
a SOM library by using:

  install.packages(c("som"));

from  http://cran.r-project.org/src/contrib/Descriptions/som.html

I got this error message:
    ld: fatal: file som.o: wrong ELF class: ELFCLASS64


I was able to fix this problem by modifying
R/etc/Makeconf and changed all SHLIB_FLAGS (with -G) to
also include -m64.


Thanks

This is not a problem with R, but with the options you selected to 
configure it.

config.site contains all the flags you might want to change.  You haven't 
even mentioned the compiler you used, let alone the flags you used.
As package som contains C++ code, it looks as if you didn't get your *CXX* 
flags right.  That's your fault, not a bug in R.

Why are you attempting to concatenate a single object?
