This is getting to be a question about gdb, and I'm no expert on that. I do remember there's a command "dir" which says where to find source; perhaps that is necessary even when the working directory holds the source. > I did not use R CMD SHLIB ( I ran the statements manually ). I don't recommend that. You can add options to R CMD SHLIB, but you are likely to run into problems with R if you leave any out.
