I'm running Ubuntu 17.04 and R 3.4.1. I installed the latter yesterday, so I presume it's the latest version. I want to install Tidyverse, which I've spent many happy hours with under Windows. But when I do install.packages("tidyverse") , I get errors about unrecognized command line options to gcc. These start when the install hits the colorspace and munsell packages. I'll show an example at the end of this post.
I've not found anyone else who had exactly that problem on Ubuntu 17.04. But posts from people with similar problems suggest that my gcc might be a version that's too old to recognise the options -fstack-protector-strong and -Wdate-time. Possible work-arounds that I've thought of: 1) Find an older version of Tidyverse that doesn't need those compiler options. 2) Upgrade my Ubuntu's gcc so that whichever one Tidyverse needs becomes the default. But I don't know whether that would nuke other software on my machine that expects an older gcc. And I don't know exactly what software the installer expects, so I'd have to keep installing different gccs until I found one that worked. (A suggestion: it would be excellent if the installer could detect such errors, then fetch and install needed software for itself. If it can't do that, couldn't it at least tell me which version it wants, instead of making me deduce it from the compiler options it's using?) 3) Install a new gcc just for Tidyverse, and somehow play with paths to fool the installer into calling it. Perhaps by following the advice in https://askubuntu.com/questions/466651/how-do-i-use-the-latest-gcc-on-ubuntu . But that sounds risky. 4) Change operating systems? I know Tidyverse works on Windows straight out of the box. Maybe it's not designed to work on Ubuntu. Anyone know?
