[R-pkg-devel] portability question

[Simon Urbanek]

Steven,

no, I'm not aware of any negative effect, in fact having an index in the archive is always a good idea - some linkers require it, some work faster with it and at the worst the linker ignores it. And as far as I can tell all current system "ar" implementations support the -s flag (even though technically, it's only part of the XSI POSIX extension, but POSIX doesn't define ranlib so ar -s is better than using ranlib directly).

Cheers,
Simon
