Hello, Trying to upgrade bioconductor hit a problem with vsn.

gcc: error: unrecognized command line option -fstack-protector-strong

It seems that "fstack-protector-strong" is a new feature in gcc 4.9 which is not part of Debian Jessie (testing) which I am running. Perhaps I could (should?) fix this by installing gcc 4.9, but that seems a bit unnatural ... so here is the question... Is gcc 4.9 really required for the latest bioconductor? Please see gory details below. Many thanks, regcl

I think the compiler flag is being picked up from your R installation; you could interrogate R for the configure flags it's decided on with R CMD config and R CMD config CFLAGS & friends. Perhaps you installed R under a different version of gcc than the one you are using to install the package with? The solution is to use the same compiler for R installation and for package installation.

Thank you. You are oh so right. I didn't change CFLAGS myself. So maybe my recent apt-get update <Rstuff> as root did.
