The problem is that this value is set really big when avxecm is available during compilation. I need to add a check that it is also available at runtime... Quote:

This wasn't obvious to me, perhaps an amendment to the .ini file to make that clearer would help.

On my installations, I always use prefer_gmpecm and this works as intended, also with 2.06.

edit: I saw this was reported earlier and should be fixed?
I pulled the newest version and did a make clean and make NFS=1 USE_SSE41=1 USE_AVX2=1 and building quits with the following error: Quote:

I wouldn't have noticed this except for some error checking in my automated parsing of factor.log

I verified the latest commits made it to github, we are now at 2.07. In this version I've committed changes to the MSVC project files and linux makefile that revert back to the "normal" directory structure of yafu and its dependencies (no more ".git" or "trunk" in the relative paths of libraries). And removed some confusing stuff in the makefile. Hopefully working toward something that is easier to build. Two other things of note: 1) I was made aware that aprcl wasn't running on factors found, this is now fixed and factors displayed to screen should now be "P" instead of "PRP" 2) AVXECM below 1040 bits is about 10% faster. Regarding the "P" vs. "PRP" labeling... the .log file still generally gets "prp" printed. Which could be fixed, but before I do that I wanted to see if that would break anyone's scripting/parsing?

We already have to handle the different format for small factors: div: found prime factor = 3 Possibly this could be changed to standardize it such that all factors follow the format (pprpc)<len> = <factor>
