And that's how it should be - there is not reason why any other code should

Ah, that works fine, and is nice and simple. So problem solved, thank
you!
I do still wonder though, with the C symbol made visible in utils.so,
That isn't true on platforms which support hiding entry points. Try
% nm -g library/utils/libs/utils.so | grep readtablehead
on Linux.
how come this still failed?:
.External("readtablehead", ..., PACKAGE="utils")
Error: "readtablehead" not available for .External() for package "utils"
Rather, you need to tell us why that should have worked .... Maybe you
failed to read in the code
R_init_utils(DllInfo *dll)
{
R_registerRoutines(dll, NULL, CallEntries, NULL, ExtEntries);
R_useDynamicSymbols(dll, FALSE);
R_forceSymbols(dll, TRUE);
}
