Installing GCC on SLES 12

I'm having trouble installing gcc on a new SLES 12 box. The goal here is actually to get R Shiny running, but when I try to install any packages I get the below error: sudo su - -c "R -e \"install.packages('Rcpp',repos='https://cran.rstudio.com/ ')\"" make: g++: Command not found This leads me to believe I need to install gcc. which gcc: which: no gcc in (/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/bin:/usr/games) gcc -version: `If 'gcc' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf gcc` This is where the trouble begins. When I zypper in gcc: `Problem: gcc-4.7-7.1.1.x86_64 requires gcc47, but this requirement cannot be provided uninstallable providers: gcc47-4.7.2_20130108-2.1.6.i586[oss] gcc47-4.7.2_20130108-2.1.6.x86_64[oss]` Ok.. zypper in gcc47-4.7.2_20130108-2.1.6.x86_64 Results: `Problem: gcc47-4.7.2_20130108-2.1.6.x86_64 requires glibc-devel, but this requirement cannot be provided uninstallable providers: glibc-devel-2.17-4.4.1.i586[oss] glibc-devel-2.17-4.4.1.x86_64[oss]` Right then... zypper in glibc-devel Results: `Problem: glibc-devel-2.17-4.4.1.x86_64 requires glibc = 2.17, but this requirement cannot be provided uninstallable providers: glibc-2.17-4.4.1.i586[oss] glibc-2.17-4.4.1.x86_64[oss]` zypper in glibc Results: `'glibc' is already installed. No update candidate for 'glibc-2.19-17.72.x86_64'. The highest available version is already installed. So somewhere in this chain of dependencies an RPM needs a lower version of something I already have. I don't want to downgrade the system. Is there some way to get the most up to date GCC that will work with glibc-2.19? Am I doing something wrong here? Am I missing a repo?
