Pass flags to R CMD check

[hadley]

e.g. --use-valgrind

[gaborcsardi]

• Command line arguments, like --use-valgrind
• environment variables to set for the build.

[gaborcsardi]

--use-valgrind is supported in e34f873. Maybe it would be simpler just to allow arbitrary arguments. The HTTP API itself works with arguments.

[gaborcsardi]

Environment variables work as well. I just added arbitrary arguments as well, for Linux.

Windows is still a TODO.

[gaborcsardi]

OK, implemented for windows as well.

How about -fno-common

[ekalosak]

I'm also curious about how to pass e.g. -fno-common to R CMD check, as it's a required flag for gcc10 compliance.

[gaborcsardi]

@ekalosak That's not a flag for R CMD check. If is a compiler flag, so you can (temporarily) put it in your package's Makevars file.

[ekalosak]

@gaborcsardi thank you for your quick response.
For others who are interested, the following adds -fno-common to the CFLAGS in a temporary Makevars - useful for running checks on code with native routine bindings.

withr::with_makevars(
  c(
    "CFLAGS"="-Wall -pedantic -fdiagnostics-color=always -fno-common"
  ),
  devtools::check()
)
