It is really not clear to me how much backwards support is worth it.
For mac os, Apple doesn't do patches for versions older than the current -1, I believe. So no one should be running 10.6 at this point as they can't get security updates. So supporting that doesn't seem worthwhile.
For linux, everywhere I have been it is either upgrade within 6 months or so of CentOS/RHEL/Ubuntu being upgraded or upgrade to every other version of Fedora. So again, its not clear that we benefit anyone by supporting older versions here either.
For windows, I don't think anyone else will manage to build IMP :-) (I failed twice), so supporting old compilers there doesn't buy us much either.
So while it seems nice in theory, I don't see that there is much benefit in practice to go far back. Has someone been at an institution where older than the above was used?

More annoying is the lack of some Boost classes and Python modules (only very very recent versions of Python ship with the multiprocessing module, for example). > > > Ben > -- > ben@salilab.org http://salilab.org/~ben/ > "It is a capital mistake to theorize before one has data." > - Sir Arthur Conan Doyle > > > > -- > Barak > _______________________________________________ > IMP-dev mailing list > IMP-dev@salilab.org > https://salilab.org/mailman/listinfo/imp-dev
