Microsoft Windows support

[joshdoe]

I know this is early, but I and I'm sure others would be interested in Windows support. I'm taking a guess that VC10 and maybe even VC11 don't have enough C++11 features implemented that would allow Halide to compile, so mingw is probably the way to go. Maybe someone more knowledgeable than I can explain some of the challenges that will be faced in porting to Windows.

A Windows port would be great. VC11 support even better. What features does it need? http://blogs.msdn.com/b/vcblog/archive/2011/09/12/10209291.aspx

There are C++11 features missing from the VC compiler which will require a little adaptation, but the real issue is just the build toolchain. Getting OCaml, LLVM, and our C++11 code all playing together is a time sink, and I have been postponing it until I have time to do it right. But it will happen (and hopefully soon).

That said, if anyone wants to take a crack themselves before I get to it, I'm glad to point them in the right direction and help with any challenges.

We've removed C++11 features to make this easier. Still working on it.

Now compiles and runs the jit tests on windows. Haven't gotten the apps working yet (mostly because I can't figure out the right way to express the build dependencies in visual studio). This path will probably break periodically because none of the active developers use windows. I'll tag this contributor project, because I would love for someone else to own this.

Windows mostly works now. The major missing piece here is porting posix_thread_pool to the win32 api equivalents.

This should actually be quite easy (like, a one hour job) for someone with the right experience and a working Windows build machine already set up. (I've been meaning to try myself forever, but keep being blocked by the fact that setting up a Windows dev VM will take easily 3x as long as doing the work in the first place.)

Also: does CUDA work on Windows?

[abadams]

Yes, cuda on windows seems to work fine on my home machine.

Thread pool done in 5b0cbf8

Still not 100% sure that the apps compile and run, so leaving this open a little longer.

Anything left?

[abadams]

I doubt OpenCL is working on windows. We've also never tested generating native client code or android code from Windows. However, the biggest thing is probably that the static tests aren't run on Windows (those in test/static), so we have no test coverage for AOT compilation.

Fixed a few things in the CMake scripts and can build the tutorials now.
For the apps a proper platform-independent way of measuring time is required instead of sys/time. C++11?
