gcc 4.8.5 compatibility about cpp11

[stefanoborini]

When is a new release going to be available for this fix?

I'm having the same issue. Also on CentOS. Also trying to install tidyr.

Suggestions would be appreciated.

cpp11 requires a compiler with full support for C++11.

What version of CentOS are you using, and what version of GNU compiler? e.g. what is the value of g++ --version

Hello @jimhester

As I said, I'm with CentOS 7

Here is the version of the C++ compiler:

$ g++ --version
g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

[yousefi138]

I'm on:
CentOS Linux release 7.7.1908

On the exact same version of C++ as @VincentGardeux

I think this is possibly due to a bug with parameter packs in variadic templates in older gcc versions like 4.8.5 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47226)

I reproduced the issue in a centos 7 docker container using gcc 4.8.5. I was then able to compile tidyr successfully after installing a newer gcc version from the devtoolset-7 software collection, following the instructions at https://linuxize.com/post/how-to-install-gcc-compiler-on-centos-7/#installing-multiple-gcc-versions

Very good catch @jimhester it works for me.
It also solves the installation of other packages.

Thanks!

Easy way to reproduce this is the following docker file.

FROM rstudio/r-base:4.0-centos7

RUN R -e 'install.packages("tidyr", repos = c(CRAN = "https://cloud.r-project.org"))'
