Did you build your own cross-compiler, or where did you get it from? log1p is definitely declared in math.h these days, but it used not to be, so that one might be due to using too old a cross-compiler. For expm1, the Windows config.h has /* #undef HAVE_EXPM1 */ which means it is declared in Rmath.h and compiled up as part of libnmath.a. Here all I can suggest is that you check the headers files are correct and that you are finding the ones for cross-compiling and not for Linux compiling (which can be a problem if the cross-compiler was built incorrectly or you configured R in that source tree without the right options). BTW, I think this topic might be more appropriate on R-devel, as most readers of R-help will not know what `cross build' is. -- Brian D.
