Hi,
I have some C++ code that I compiled into a dll for use in 32 bit R and
would like to recompile for use in 64bit R. I thought it would be as easy
as going to R-2.15.0\bib\x64 and running R CMD SHLIB mfregRF.c
Is this Windows?
1. If so, is your OS 64-bit? Otherwise that R won't run for you.
2. Do you have the latest toolchain first in your PATH?
3. Do yo follow the details of the most recent version of the R
Installation and Administration manual?
Uwe Ligges
but that doesn't do anything. It doesn't give me any error messages, but
it also doesn't create a shared (so) file. I just get the command prompt
back.
I also tried \bin\x64 R CMD SHLIB - help, and again got nothing but the
command prompt back.
Just to check, I ran R CMD SHLIB from \bin\i386 on the same C++ files and
it produced a working dll just like usual.
Is there something that I need to do to the C++ files to make them
compatible with 64 bit? They are not file that I made, so I do not know
how they were originally compiled.
Thanks for any help.
