My Makefile has the lines as quoted.



Hmm, looking closer at the Makefile, I don't have a 'gmp/include' or 'gmp/lib' folder, is that the issue? Should it point to /usr/local/ or something?

Guide to compiling YAFU

Since we're not getting new YAFU binaries, can someone post a guide to compiling it yourself? It's not my area of expertise and I seem to always fail on some dependency.

Thanks for all the ideas so far!

Any particular motherboard/case recommendations?

Any significant impact from DDR3 vs DDR4 memory?

I just factored a C148 with SNFS in 26 hours (vs. ~120 with GNFS).
