That's the useful piece of information that goes beyond just CentOS5 + RH devtools + static linking -- can't tell of the "Holy Build Box" has anything like that.
Probably-crazy Idea: One could reconstruct that list by downloading all of https://repo.continuum.io/pkgs/free/linux-64/, untarring everything, and running `ldd` on all of the binaries and .so files. Can't be that hard... right? -Robert On Fri, Jan 8, 2016 at 8:03 PM, Nathaniel Smith <n...@pobox.com> wrote: > On Fri, Jan 8, 2016 at 7:41 PM, Robert McGibbon <rmcgi...@gmail.com> > wrote: > >> Doesn't building on CentOS 5 also mean using a quite old version of gcc? > > > > I have had pretty good luck using the (awesomely named) Holy Build Box, > > which is a CentOS 5 docker image with a newer gcc version installed (but > I > > guess the same old libc).
