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
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. - Katharine [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
