Sage 7.6 compilation - gsl and r failures on Linux

[Tae Lim Kook]

Sorry if a similar message previously appeared on this group. I'm assuming that it didn't get posted for some reason.

OS: Linux (kernel 4.10.0 / distro: Ubuntu 17.10)
GCC version: 7.0.0 20161202 experimental (built from source)

[Dima Pasechnik]

IMHO you are the 1st one reporting about building Sage with gcc 7.0.0.

It's not surprising - most probably the corresponding upstream packages, gsl and R in this case, have not yet been ported to gcc 7.

[Dima Pasechnik]

First thing you might like to try is to update to gcc 7.0.1;

see the related Fedora effort:
