Readr installing failed

[tarmenic]

I cannot get readr to install, neither via R install.packages nor via github. While everything of the tidyverse (so far) seems to install fine, with readr I always get:

** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object '/usr/local/lib/R/site-library/readr/libs/readr.so':
  /usr/local/lib/R/site-library/readr/libs/readr.so: undefined symbol: write_connection
Error: loading failed

My session info is:

The system is completely newly set up. R is installed via apt (r-base and r-base-dev) and run with sudo. Google did not seem to know the specific "write_connection" error message. Any help would be appreciated.
Thanks.

Similar issue on macOS with current R version...

We are in that period between a new readr version being on CRAN but binaries are not yet available.

@JeffreyRacine I assume you saw something like this when installing?

  There is a binary version available but the source version is later:
      binary source needs_compilation
readr  1.1.1  1.2.1              TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel)

I am able to successfully install readr v1.2.1 from CRAN, with compilation.

Are you @JeffreyRacine generally set up to compile packages from source?

[JeffreyRacine]

Greetings,

Installed from source... no issues with other packages...

Not sure if this helps with my original problem, but at least FYI: @jennybc I saw that message on Windows earlier today. I have just installed the 1.1.1. on a Windows R 3.5.1 as binary and then updated with compiling from source to 1.2.1. That went fine.

[jimhester]

The 1.2.0 release inadvertantly broke support for R versions prior to 3.2.0, it will be fixed in the near future, however in the meantime I would suggest you update your version of R to something more current.

[tarmenic]

You already closed it, but FWIW:
The issue is indeed gone after updating to R 3.5.1. (For other readers with my config: See https://cran.r-project.org/bin/linux/ubuntu/ and make sure to update the packages installed before as well w/ checkBuilt=TRUE)

Thanks for your help, @jimhester

[jennybc]

FWIW I note that @JeffreyRacine is on macOS and R 3.5.1.

[MichaelChirico]

@jimhester you said

prior to 3.2.0

but I just encountered this on 3.2.3, FWIW

Pushing to update R...

[jimhester]

@MichaelChirico this should be fixed on readr 1.3.0, which was just uploaded to CRAN today.

[JeffreyRacine]

Sorry, still failing to install on latest R and macOS versions...

@JeffreyRacine why are you specifying -arch x86_64?

I would suggest you use the CRAN distributions of R, anything else is not likely to be tested by package authors.

Greetings Jim,

Thanks for the suggestion, however, I have used these settings for perhaps a decade or more... I don't want the extra 32 bit stuff hanging around, and the x86_64 architecture compile flags were suggested by members of the R core team for what that is worth... readr is the only package currently failing to compile, and I have hundreds of packages installed...

Jeff
