[R-pkg-devel] Solaris segfaults

[Gábor Csárdi]

Hi Ben,

According to https://www.stats.ox.ac.uk/pub/bdr/Rconfig/r-patched-solaris-x86
CRAN's Solaris is also 32 bit.
But maybe I am missing something?

You can download a Solaris VM (for Virtualbox or VMware) from
https://files.r-hub.io/solaris/
It has both 32 bit and 64 bit R (with gcc) and ODS R as well. You can
update R on it like this:
https://github.com/r-hub/solarischeck/tree/master/packer#updating-r

Best,
Gabor
