[R] Installing ranger package in Ubuntu 14

[Iván Blanco]

I'm trying to install ranger package (any version) in Ubuntu 14 from a tar.gz file already downloaded, but unsuccessfully. System admin has already installed gcc 5.4 and g++ 5.4 and I've created a ~/.R/Makevars file pointing to these compilers instead of gcc 4.8 that comes in Ubuntu 14 by default.  Ranger requires gcc 4.9 or higher. That Makevars file looks like this:

CC=/storage/home/user/bin/gcc-5
CCXX=/storage/home/user/bin/g++-5
FC=/storage/home/user/bin/gfortran-6
F77=/storage/home/user/bin/gfortran-6

I don’t have admin rights and system admin can't change gcc path for the whole server. Output error is this one:

=========================================

==============================================

It seems I’m missing some flag defintion in my Makevars and R is using the default gcc 4.8 compiler, I don’t know. Any advice about how to procceed would be very helpful. Thanks.

Kind regards,

Ivan
