Here is a further attempt to solve the threading issue in the Visual Studio build of msieve. I would be grateful for any tests that can be run with it.

Hello Brian, all of your previous binaries have worked for me (meaning they run and provide some functionality). Probably because I saw a previous note to download a certain vc_redist with a link posted by frmky. This latest binary does not work for me at all. When I try to run it, it says that it is missing a vcomp120.dll. I tried searching Google, but that returns zero results. Is there any way that you can make this a static binary that does not have any external dependencies? If not, can you provide a link to where I can download this vcomp120.dll?

Hi David,

I suspect that this issue is a result of a update 3 for the Visual C++ redistributable package that occurred in late June. This is available [URL="http://http://www.microsoft.com/en-gb/download/details.aspx?id=30679"]here[/URL] and probably contains the files you need. Please let me know if installing this doesn't solve the problem.

Jeff Gilchrist provides a link to the necessary redistributable packages on his web site [URL="http://http://gilchrist.ca/jeff/factoring/index.html"]here[/URL], which is why I prefer to make binaries available there (I only provided a few here in the hope that this would speed up the debugging process).

Unfortunately, as far as I am aware, there is little I can do to avoid this 'redistributable hell' as I don't think there is any way of bypassing these core dependencies.

The good news is that your C120 completes for me with this binary.

The update 3 for Visual C++ from [URL="http://www.microsoft.com/en-us/download/details.aspx?id=30679"]www.microsoft.com/en-us/download/details.aspx?id=30679[/URL] solve the Problem for me.

[QUOTE=Brian Gladman;346741]I am using the msieve SVN - the automatic SVN output doesn't work in Visual Studio.

For those of you used to seeing the SVN build in the Windows binaries, that is an extra service I provided by manually putting it in before compiling because I always liked to see that.

After people get a chance to test Brian's latest binary and confirm it is ok, Brian please send me the latest good version that you want me to put on the website.

Unfortunately, this does not solve the problem. It looks like this is the one that frmky pointed to earlier (post 132) and that I already had downloaded and installed. I went ahead and downloaded the 32-bit redist also, ie I now have both the 32-bit and 64-bit installed, but it still says vcomp120.dll not found. I pulled up dependency walker and found out that this msieve.exe is also missing ieshims.dll. From just a quick search, it seems like that dll was only necessary on XP. Did you perhaps compile this for a specific OS, like XP? Or, since frmky's post talks about a missing vcomp110.dll, did you perhaps switch to a different compiler, like Visual Studio 2013 (instead of 2012) for this binary? Hopefully we can figure out how to get this to work. Please let me know if you'd like me to try anything.

Hello,

When I run the following with Linux Ubuntu 12.04 64-Bit:
msieve -s C238_121_93.dat -l C238_121_93.log -i C238_121_93.ini -nf C238_121_93.fb -t 4 -nc

I keep getting the following error:

Note: msieve works fine on factoring smaller c70.

Mathew, the C70 would have used the quadratic sieve, whose code is much simpler than the NFS used in your large test.

Your crash occurs while using GMP (or MPIR). I wonder if it's because GMP has a problem or is only being given something wrong...
