Hi, Thanks for the suggestions. I've forgotten to point out, that
R CMD COMPILE and R CMD SHLIB works fine, the dll file was indeed created. I get these undefined references when I'm trying to run R CMD INSTALL. I've read through the "Writing R extensions" and the archives, but I really don't know what am I doing wrong. More suprising, when I run the same package in windows with R CMD check, the dll for src-i386 was created, but not the 64 -bit, i'm getting: sorry, 64 bit compilation not supported (or someting similar) If anyone have an idea, comments welcome.
