Error installing package r-3.1.2.p0
I want to install sage-6.5 from source code, but I encounter the message "Error installing package r-3.1.2.p0". I have tried to use "SAGE_INSTALL_GCC=yes make", it fails too. My platform is Ubuntu 14.04 x86_64. I find the error message in the log file:
/home/steven/Documents/Softwares/sage-6.5/local/var/tmp/sage/build/r-3.1.2.p0/src/bin/exec/R: /usr/lib/x86_64-linux-gnu/libgomp.so.1: version `GOMP_4.0' not found (required by /home/steven/Documents/Softwares/sage-6.5/local/var/tmp/sage/build/r-3.1.2.p0/src/lib/libR.so)
I don't know how to fix it. Can someone be helpful?
