Test if compilation appears possible. This is used in some
examples, and tries compiling a trivial C program with
pkgbuild. Results are cached between runs within a session
so this should be fast to rely on.
can_compile(verbose = FALSE, refresh = FALSE)
Be verbose when running commands?
Try again to compile, skipping the cached value?
A logical scalar
pkgbuild in order to build packages, and it includes a
set of heuristics to locate and organise your C compiler. The most
likely people affected here are Windows users; if you get this
ensure that you have rtools installed. Using
debug = TRUE may be helpful for
diagnosing compiler issues.
