I like the idea of branching (cheaply) whenever I feel like, and committing before merging. SVN doesn't offer those :P

(That is to say, I've been spoiled by Git)

You can use Git on top of SVN to get most of its benefits: Git has almost always had excellent two-way interoperability with SVN, unlike Mercurial which got it years later
In my three different jobs since 2007, the central repositories were / are SVN, and I use(d) Git for myself directly on top of the SVN repo, so as to be able to use cheap branching, rebasing, history rewriting, etc. I can't live without those features either, since I started using them.

B^2 - It's been a couple of years since you uploaded a new binary, any chance you could? Thanks!

Hi Ben,

Have you given up on the Visual Studio build?

Not at all! The Visual Studio IDE is my development environment of choice, although I only use the Microsoft compiler for the 32 bit windows version. For 64-bit windows I use mingw64 for its 64-bit assembly language support.

Thanks Ben,

It doesn't build for me in either 32 or 64 bit mode :-(

I haven't tried it in a while (see Mr. Odd's post above) so I guess I'm not surprised. I will take a look. Hopefully it is something small.

I have also tried the Intel compiler in x64 mode as this can cope with GCC style assembler but this also fails.I have had to add a number of files to the build that were not present - maybe I have added too many?

I have to go out for a while but I will take another look later this evening.

What's wrong with this:

C:\Users\User1\Desktop>C:\Users\User1\Desktop\yafu-1.34\yafu-x64.exe ecm(@,9)
-batchfile em.txt -ecm_path C:\Users\User1\Desktop\yafu-1.34\ecm\ecm.exe -B1ec
m 3000000 -B2ecm 8000000000 -threads 3

I believe I just used these commands succesfully, but now I get the following:

fopen error: No such file or directory
couldn't open em.txt for reading

Maybe I accidentally changed something that I am now blind to.

Also; are the SNFS-polynomials that YAFU creates good? Are there special cases when they should be particularly good/bad?
Could YAFU generate SNFS-polynomials for trinomials such as 2^m+2^n+1?

[Dubslow]

Looks like your batchfile went missing. Try `dir` to verify that it still exists.

Search the docfile for "snfs(", it documents which SNFS forms are supported (I don't believe trinomials are). For supported forms, the polys generated "should" be optimal. (In most cases several candidates are test sieved to be sure.)

I was about to ask the same question. Bsquared, Please update the binaries, because I've been stuck at 1.33 (SIQS won't work in 1.34 binary for some reason), which has that "C1=1 at end of factorization" problem.
