I am confused by this.
So in order to test this, I just triggered rebuild of the smaller drd ("daily
r-devel") and r-devel Docker images for R.
Using drd, I used R 3.3.3 to install digest and anytime (also installing Rcpp
and BH). I then launch the R-devel build freshly created, and reported as
root@b00daf469882:/# RD --version
R Under development (unstable) (2017-03-21 r72380) -- "Unsuffered Consequences"
yet both digest and anytime loaded fine by R-devel. Despite the fact that
they were installed by R 3.3.3.
None register C/Fortran routines for .C or .Fortran.
My belief is that packages which register more than one .C or more than
one .Fortran native routine are affected, but that may not be exhaustive
(and might depend on the compiler).
As I understand your email, that should not have worked. So I must be
missing something -- can you help set me straight?
All packages should load ... the issue is finding (all of the)
registered symbols. Here's an example of what can go wrong, x86_64 Linux;
> library(mgcv, lib = "/usr/local/lib64/R/library") # R 3.3.3
Loading required package: nlme
This is mgcv 1.8-17. For overview type 'help("mgcv-package")'.
> mgcv:::in.out
...
um <- .C(C_in_out, bx = as.double(bnd[, 1]), by = as.double(bnd[,
...
> mgcv:::C_in_out
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
object 'C_in_out' not found
(the last message being found in testing a package which called mgcv).
