How to backport recent Boost packages to older ubuntu distro's and build using personal PPA

Boost backporting

Goal here is to document the steps I took in May 2012 to get Boost 1.49 packages backported and working on Lucid, Maverick, Natty, Oneiric, and Precise.

TODO: look into using ubuntu-dev-tools and backportpackage -s [new_release] -d [old_release] -u [ppa] [package_name]

Install dev tools

sudo apt-get install debhelper devscripts dput git-core python pgpgpg

Iterating Combinations

Iterating Combinations

If you're trying to iterate all combinations of k=5 on n=36, this is how you loop through them.

int k = 5;
int n = 36;
int count = 0;
for (int i1=1; i1 &lt;= n-k+1; i1++)
