Ocelot does not build on windows

[GoogleCodeExporter]

The title says it all, we need someone to actually step through the entire 
build process on windows.

Ocelot uses functions provided in cfenv/fenv.h. This header file is not part of 
MSVC standard library implementation.

Has anyone got around this isse? Perhaps by changing the source/ supplying own 
functions etc?

Thanks,
Ganesh

See 
http://code.google.com/p/gpuocelot/source/browse/trunk/branches/ocelot-windows/o
celot/executive/implementation/CooperativeThreadArray.cpp?r=1001 for what I did 
to get around this the last time I tried.  I couldn't immediately find an 
equivalent to fenv on windows so I just turned it off.  Ideally, we would want 
a way to set the rounding modes on windows...

The FPU rounding mode can be set via _control87 on Windows, see
http://msdn.microsoft.com/en-us/library/e9b52ceh%28v=VS.100%29.aspx

If there's currently no one working on Windows support, I'd be willing to give 
it a try.

Thanks for the link.  I think that we would have to do something to ensure that 
once we set the mode, the x87 FPU is used rather than the SSE unit (which I 
think most compilers end up choosing by default).  Also, we would probably want 
to wrap both fenv and _control87 behind a wrapper library.

I don't think that anyone is working on this now, although I am tracking it.

If you are willing, I would encourage you to give it a try.

Issue 32 has been merged into this issue.

I'm currently working on compiling gpuocelot with VS2010 and will hopefully be 
able to send some patches to the mailing list soon.

There is currently support in the source code as well as the build system for 
windows.  I need someone to independently try this out and verify it.

I'm up. What is needed?

I added some experimental build instructions to the Installation wiki page.  
You need to make sure that you have all of the prerequisites installed and then 
try out the commands listed.

any news about this subject? I would like to use it on my windows. Thanks.

I believe this has been resolved quite some time ago already, starting with

All right, but I see no version, or public package available for windows... 
there is any possibility to see this?

Thanks.

I'm currently leaving this open until we have a library available on the 
website.

Thanks for the info. I will wait for news about it, because I plan to use 
Ocelot in many projects for windows I am developing, I have many cuda codes 
that needs to be executed on AMD GPU or CPU (My desktop currently have a 
low-end Nvidia card, one high-end AMD card, and an 2 x 8 core cpu, and I will 
greatly take benefit if I could use all of them at the same time). Best 
regards. Thanks.

There is preliminary support for building on windows.  Just run build.py from 
the command line.  

The emulator is supported (although there are a few minor issues with rounding 
modifiers that makes floating point precision slightly different than on linux 
in some rare cares).

The multicore CPU backend has been tested a few times.

The NVIDIA and AMD backends build, but they have not been tested.  

It would be useful to have someone donate a windows machine for running 
regression tests.

Very nice! I am going to try this. But for what I saw, in the code, I feel it 
is a very nice piece of tech, very well written. Thanks very much! 

PS.: I dont found the Opencl backend, it is me, or it is really not present at 
the moment in trunk?

PS.: I saw here to find details about how to build for windows, 
http://code.google.com/p/gpuocelot/wiki/Installation , but, it seems something 
is omitted. A little more details would not hurt.

Hi, is it still possible to get the codes somewhere? I have VS 2010 
Proffesional at my disposal and since my laptop doesnt have NVIDIA card, I 
would like to use Ocelot to emulate it in Windows environment. While I was able 
to get Ocelot working after about day and a half on Ubuntu 12.04, I wont be 
able to use it for active development since everybody around uses VS to develop 
CUDA apps. I can imagine it being pretty painful to keep linux and VS project 
synchronized. I am working on a naive "hybrid" solution involving virtual 
machine with linux and a shared folder containing project sources hosted on the 
host computer. Then, in theory, it could be possible to edit all files in VS, 
switch to virtual machine, compile the stuff in linux and see the result there 
too. Its just a thought, though, how efficient and comfortable that can be, no 
idea.

Still, if I could download the Windows sources for Ocelot from somewhere, I 
would certainly give it a try. Is there still such a place available, please?

I've actually managed to get Ocelot to compile under win7 with 2010 pro in both 
32 and 64 bits after some work, but now when I try to link the ocelot.lib it 
complains about missing symbols.

for a very basic program that does nearly nothing:

I could definetly see about donating a windows machine to help further develop 
this project (if that's what's really needed, maybe it's actually more devs. 
that is needed?).

Meanwhile I'm also gonna give the windows build a go... How many have been 
successful so far?
