It will be much quicker to install Ubuntu onto a USB stick than to try to get this to build on Windows. Code: % git init % git clone git://gdlog.git.sourceforge.net/gitroot/gdlog/gdlog % apt-get install apt-file % sudo apt-file update % ./configure repeatedly do 'apt-file search X.h' when it says X.h is missing % make Put Code: p: 20000000000000000000000000000000024219 q: 10000000000000000000000000000000012109 job: file sieveType: page into a file (p is the prime, q is the largest prime factor of p-1), then do Code: python path/to/progs/gdlog.py --path=path/to/progs file (you have to run the python command from the directory 'file' is in; otherwise it sieves forever) and off it goes. It uses all your cores. Read README to figure out what to do when the sieving is done. Last fiddled with by fivemack on 2011-08-29 at 12:32

Code: base: 47 modulus: 112624315653284427036559548610503669920632123929604336254260115573677366691719 result: 107169838909122878937980510796152643759453843830224828060309998762431169006781 R.D. Silverman, i meant same as written above, not a description of the calculations. I can google, i am just not a mathematician.

Yes, I can answer. But I won't. I only take the time to answer questions
from people who show a willingness to LEARN. Your posts have shown a
disdain for learning.

At the risk of repeating myself:

To learn WHAT? I already said i'm not a mathematician and i don't want to learn everything you know because i have my own specialization which is different from yours. That program is full of mathematical variables i don't undestand, for example, what is p and q? If you'd got a kick every time you asked anything you have no idea of on the internets, maybe you'll behave yourself another way.

You have not told them WHY you are interested in this problem, and your general lack of mathematical or programming interest in this mathematical problem indicates a practical interest you won't state. So the suspicion that you(O/P) are up to no good is quite reasonable, and the level of help you have here is actually extraordinarily high. I invite evidence from the O/P to the contrary of what I have stated; it is not a proof, only a strong circumstantial case.

Then WHY are you interested in a discrete log problem? You don't even
seem to understand a statement of the problem!

Go to a medical convention. Tell them: "I'm not a doctor and I don't
want to learn any medicine, but please teach me how to perform brain
surgery".

The request is ridiculous.
