It is 1.08.

I think you need to kill and redo the process.

The errors show that you either do not have the cat.exe file at all, or you do not have specified where it is.

After killing the process, do:

1.) Make sure that you have got the cat.exe and grep.exe files both in the same folder.
2.) If you don't have these files, you can download the Linux utilities, containing these two files, here.
3.) Open your FactMsieve.pl file (for editing) and find the line $SYS_BIN_PATH="" 4.) Add your path where you have got your cat.exe and grep.exe files like this:$SYS_BIN_PATH="c:/mingw/msys/1.0/bin". (note: factmsieve.pl does not accept the backslash (\) in path names, use the slash (/) instead.)
5.) Restart aliqueit.exe and make sure to use the -e option to skip ECM for the first factorization.

What Andi said, plus: you appear to be running the 64-bit version of the gnfa-lasieve* sievers. You probably don't want to do that. They are slower than the 32-bit versions (due to lack of asm) and spew a lot of unwanted garbage to the screen for some reason.

 2009-04-01, 18:41 #104 Joshua2     Sep 2004 13×41 Posts Ok, so I should be using http://gilchrist.ca/jeff/factoring/g...0-win32-p4.zip instead of the core2 duo x64 version? I did what andi said now I'll try this. So I think I'll just transfer the gnfs-lasieve files from the 32 bit and keep all the other stuff 64 bit. I use msieve for everything I can too. Does this sound good? Edit 32 bit seems to be giving me .005 sec/rel instead of .006, so about 15% I suppose. Is there no way to run a good 64 bit version w/ cygwin or anything better?

Sounds good to me.

I don't think so. I'm currently trying to get a faster 64-bit windows .exe working, but it's not there yet.

 2009-04-01, 19:25 #106 Joshua2     Sep 2004 13×41 Posts Looks like its still not fixed. $SYS_BIN_PATH="c:/cygwin/bin"; is what I have. I did$GGNFS_BIN_PATH="C:\\\Program Files\\\ggnfs"; and it seemed to work, was having errors before on that one. Should I switch to the 3 backslash? Edit: also, each time I restart I lose all the sieving I've done, its getting annoying... Attached Thumbnails   Last fiddled with by Joshua2 on 2009-04-01 at 19:27

That doesn't seem to be the problem: the command for cat.exe seems to be just "cat", not "$SYS_BIN_PATH/cat.exe". Could you please attach your factMsieve.pl? (I'm a veteran of path errors. I have had many of them in the past.) 2009-04-01, 19:29 #108 Andi47 Oct 2004 Austria 2×17×73 Posts Quote:  Originally Posted by Joshua2 Looks like its still not fixed.$SYS_BIN_PATH="c:/cygwin/bin"; is what I have.

Should I switch to the 3 backslash? the error Code: sh: cat - command not found indicates, that it does not find cat.exe (and therefore WILL fail). c:/cygwin/bin should work, rather than with \\\. 2009-04-01, 19:32 #109 Joshua2 Sep 2004 10258 Posts Canceled it, and it looks like it deletes everything, along w/ another cat error. Is it supposed to save automatically and resume? Prob from not using win32 but win 64? if ($^O eq "MSWin32") {
I think I just delete the if and else and hard code it.

I've attached a new version. I think it should sort out that problem.
