Hello,

I'm using R for statistical computing. GRsec/pax enabled, when attempting to compile R packages from within R, I have some trouble, an error failed to map segment from shared object. thanks for any help/guidance.

Here's what the output looks like.

Code: Select all

have you got related kernel logs perhaps? also can you post the output of readelf -edW /home/user/R/x86_64-pc-linux-gnu-library/2.15/zoo/libs/zoo.so please?
