[R-pkg-devel] Compilation used the "non-portable flag"

[Goldfeld, Keith]

Good afternoon –

I am submitting an update to my package ‘simstudy’, and the ran the rhub checks. I received a note from one of the four platforms (the other three passed). The Ubuntu Linux 16.04 objected to the compilation flags:

* checking compilation flags used ... NOTE
Compilation used the following non-portable flag(s):
  ‘-Wdate-time’ ‘-Werror=format-security’ ‘-Wformat’

I did some searching and someone suggested I create a ‘Makevars’ in the ~/.R directory (which is different from my package directory). This is what I included in the Makevars file:

# Settings from /etc/R/Makeconf with "non-portable flag(s):"
# ‘-Wdate-time’ ‘-Werror=format-security’ ‘-Wformat’ replaced by -Wall -pedantic
# and without -fdebug-prefix-map=...
CFLAGS = -g -O2 -Wall -pedantic -fstack-protector-strong -D_FORTIFY_SOURCE=2 $(LTO)
CXXFLAGS = -g -O2 -Wall -pedantic -fstack-protector-strong -D_FORTIFY_SOURCE=2 $(LTO)
CXX98FLAGS = -g -O2 -Wall -pedantic -fstack-protector-strong -D_FORTIFY_SOURCE=2
CXX11FLAGS = -g -O2 -Wall -pedantic -fstack-protector-strong -D_FORTIFY_SOURCE=2
CXX14FLAGS = -g -O2 -Wall -pedantic -fstack-protector-strong -D_FORTIFY_SOURCE=2

I ran devtools::check(), and it seemed to find the Makevars file. However, when I reran devtools::check_rhub(), I still received a NOTE. Does anyone have any advice on what I might not be getting right?
