Ubuntu builds https://launchpad.net/~marutter/+archive/ubuntu/rrutter3.5 with sources if you want to know more. Based on my Debian builds which you can peruse at https://salsa.debian.org/edd/r-base That said, R 3.5.0 is _not_ compatible with R 3.4.* and before so if you install these binaries expect _all_ old R packages, whether from r-cran-* or locally installed, to croak. Which is why R 3.5.0 is not yet mirrored at CRAN -- we're just not there yet. | tried may things, including : | | export LDFLAGS="$LDFLAGS -fPIC" | export CXXFLAGS="$CXXFLAGS -fPIC" | export CFLAGS="$CFLAGS -fPIC" | ./configure --enable-R-shlib --prefix=/usr/lib/R/3.5.0 I am not sure where you got those settings from. That is (AICR) not what it is in the R Installation + Administration manual which you should consult if you insist on doing it locally. I have a fairly strongly held conviction that the available binaries are actually better for you (we make many informed choices for you and add several bells as well as a few whistles) but you are free to ignore it.
