I'll try at somepoint today. The problem is (currently) when I boot to Linux, no GIMPS work gets done, and it'll probably take a while to get everything working, so I haven't been in Linux for a while. Like I said though, I'll try later today.

msft, he was having compiling problems, so that's why he was looking for a precompiled version.

Edit: Oh yeah, can't play TF2 either in Linux, though I have heard about various Wine-based options to get it working.

I remember why I wasn't booting Linux: About a month ago, after I tried updating the nVidia drivers, my GUI stopped working. This might take a bit longer than expected :/

Edit: Well, I tried updating the driver again (booted to Windows and dl'ed it to flash drive) and got the installer to run, but didn't help the GUI-not-starting-on-boot issue. The terminals worked fine though, so I extracted the executable and necessary library-type files. The weird thing is, when I tried to run mfaktc, it said my nVidia kernel module reported a 270.x.xx version number, but I'm pretty sure I haven't ever used anything earlier than 280.x, and during the 285.x install it said it had updated the kernel module.

Anyways, as far as the CUDALucas goes, for the life of me I couldn't get it to find the library files required, so I eventually put them in a lib subfolder of the folder containing the binary. That's how the zip is organized. (Quick note: The files the binary will look for are like 'name.4' or similar, whereas the files I gave you are 'name.4.0.17'. Just create a simlink with the right name.)

Edit: Hmm, not letting me upload the zip. Throws some error about security tokens, and when I hit the "inform the administrator" link, it says I don't have permission.
Edit2: Try this: http://filesmelt.com/downloader/CUDALucas.zip

Thank you very much, this is what I was searching for. I tried to compile it from that zip file, what was probably intended to use primary in Windows and setup.cu was missing there.

The source from this file compiled fine.

And, all my work with compiling, etc., was useless, because this program requires 1.3 CUDA capabilities. Great...

Add msec/Iter.

Is the 1.3 release official then? I remember seeing a 1.2b and wondering what that was...

I was not successful compile.

Hi,
I can't get it to run on Linux. Compiled the 1.3 source with just 'make'. Running a single GTX 460 on a Z68 motherboard.

I had this same problem with 1.2 a couple of months ago, but I gave it up then and ran mfaktc, which ATM also isn't working.

Yes, this is CudaLucas V1.2b Linux64-bit, but works fine.
Please let me know if this works for you!
