can_compile | R Documentation |
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)
verbose |
Be verbose when running commands? |
refresh |
Try again to compile, skipping the cached value? |
We use 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
pkgbuild::find_rtools()
with debug = TRUE
may be helpful for
diagnosing compiler issues.
A logical scalar
can_compile() # will take ~0.1s the first time
can_compile() # should be basically instantaneous
