[Rcpp-devel] Error installing 1.0.13

Wed, Jul 24, 2024 5:02 PM

Hello, Dirk.

Now that you mention it, ny R is a bit old. I'm running (r-devel of
course) 2024-05-12 r86534 ucrt.

Let me rebuild R from scratch and I'll try again. I'll report back (in
a day or so) if that helped.

Thank you!

Avi

That's not a good outcome and a little odd.

We can see that CRAN has Windows binaries, and, upon upload, of course also
first checked with default Windows and Linux build servers by Uwe and Kurt.

As for the error, the file compat.h is pretty trivial and just contains a
version comparison to then define the replacement wrapper. Line 34 _defines_
a string rather than using. So I am puzzled.  Maybe something
is off with your R version?  You often run r-devel, don't you?

In any event, if your R is newer than 4.4.2 maybe (for now) replace the
conditional logic in compat.h with just the defines ie

  # define RCPP_STRING_PTR STRING_PTR_RO

  # define RCPP_VECTOR_PTR VECTOR_PTR_RO

and use that?
