HHVM Installation in windows

[ricker07]

Is there any way to install HHVM in windows 7, because i read about the new programming language by facebook and it requires HHVM for development. thanks in advance for an answer.

The easiest way is to install an Ubuntu VM and run HHVM inside that. There's no Windows version of HHVM available and it doesn't currently compile on it at all.

It's nowhere close to being able to compile it properly from windows. I've been working on adding MSVC support for a few weeks now, and I've only just gotten through adjusting the build system and most of its dependencies. Currently I'm also waiting on the RTM for VS 2015 to be released to fix a number of constexpr limitations (all but 1 that I know of are fixed in the RTM version) that are present in the RC, and are heavily used in HHVM's source code.

hmm. your saying that there's no way to install or run HHVM in windows? :(

Not currently. I'd do what @simonwelsh is suggesting for now.

+100 for this. I've been waiting for Windows version for about a year now. A build for development would be good enough.

@raeesiqbal Same here +1

There's a lot of ongoing work here (thanks @Orvid!), my understanding is that it can now be built (perhaps with some outstanding patches to master?) but still isn't stable enough to run on windows yet.

[RaeesBhatti]

I see that Building and Installing HHVM on Cygwin and Building and installing HHVM on Windows with MSVC have been updated recently and there are a lot of outstanding PRs. So, there has been a lot of progress, lets pray that they make it work soon.

I had spent about a week trying to get the typechecker to work on CYGWIN a few months back but it didn't, so, wont make the same mistake again 😄.
@Orvid when you've built the typechecker binaries successfully, please let us know.

A first pass at a windows build system for Hack is up for review at #5775.

[Orvid]

With some outstanding patches to a version of HHVM from the start of June, MSVC 2015 can build HHVM, it is not however functional, as there is still some work I need to do in the startup process. My intention, once I finish putting up the PRs to Folly, is to start again, merging all my outstanding PRs, and see where that puts me in terms of what still needs to be submitted, what bits are temporary hacks that need to be implemented properly, and what changes are no longer needed in the master version.

I know there are also some changes that have to be made to the way some of the external dependencies are built by default, due to wanting to not try to ship a massive number of external dlls, primarily needing to have them target the static runtime rather than the dynamic one. There are even some changes needed to Boost (0.58.0) to make it compatible with MSVC 2015, although, if I were to build from the HEAD version, I don't believe those changes are needed due to a refactoring that was done for WinRT support.

Also, there's a reason the MSVC page isn't linked to in the normal instruction list, and that is that I've barely touched it. I started writing it up at one point, but ended up stopping before I got too far due to the fact there would have to be changes once the RTM version of VS 2015 was finally released.

The typechecker does not currently work on Windows, although I did have a version that compiled with a bit of work, it was not done in a way that was viable to build normally. The build system that's currently up for review is significantly more viable than the way I was doing it. (I had to call the build script 5-8 times to get it to compile with my method, and that wasn't exactly fast :D)

@Orvid any updates on typechecker?

[Orvid]

@OCamlPro-Henry has been doing a lot of work towards the typechecker, I've not really touched it since my initial attempt. He can probably comment on what currently works much better than I can.

As far as support for Windows in the core of HHVM, I have a (very) large number of open PRs dedicated to making that happen.

@raeesiqbal We (I and @OCamlPro-Bozman) have a working typechecker. It passes the testsuite and, for instance, it is able to typecheck https://github.com/Titon/framework. Though, we still have to implements file watching and a proper timeout handling. While, not everything has been merged yet, the pending PRs should be sufficient for running the typechecker. I will add a message here when master contains a running typechecker.
