Leveldown failing to compile on win 10

[kde99]

Hello everyone!

I'm trying to install level and it fails at installing leveldown. I have windows 10 and visual studio 2015 (newly installed) also the newest node-gyp (v2.0.2) Nodejs is 0.12.7 my pc is a 64bits system. The headers are not missing and there are placed in the correctly.
npm-debug.log

[No9]

This looks the same as #196

[ralphtheninja]

@No9 Thanks for replying to this. I'm completely in the dark when it comes to windows these days.

[kde99]

@No9 It can be #196 but I don't understand what was the fix for it back then and also I wanted to let you know that this error is still there even in a newer version.

[No9]

@kde99 So there isn't a solution in #196 :(
I was just flagging it for consistency

Fortunately I installed the Rust plugin for VS 2013 last week and it has completely killed my VS 2013 so I am going to put 2015 on today and see if I can replicate this.

My working assumption at the moment is that there has been a change to the default behavior of VS builds and we are going to need a flag of some sort. (Totally guessing right now but lets see)

[No9]

@kde99 FYI I can now replicate this locally on my VS 2015 install

[ralphtheninja]

👍

[No9]

Hey @kde99
I made progress on this tonight and as with all good assumptions I got it completely wrong :)

What has happened is M$ have decided to be good citizens and start implementing some of the standard language features so we don't need to supply level implementations anymore.

The immediate workaround is to replace

  #include "stdint-msvc2008.h"
  #define PLATFORM_IS_LITTLE_ENDIAN true
  #define snprintf _snprintf

in /deps/leveldb/port-libuv/port_uv.h
https://github.com/Level/leveldown/blob/master/deps/leveldb/port-libuv/port_uv.h#L29

With

#if _MSC_VER < 1900 
  #include "stdint-msvc2008.h"
#endif
  #define PLATFORM_IS_LITTLE_ENDIAN true
#if _MSC_VER < 1900 
  #define snprintf _snprintf
#endif

And delete this file completely
/deps/leveldb/leveldb-1.18.0/port/win/stdint.h

This should compile for you with a single warning but that should be ok.

c:\leveldown\deps\leveldb\leveldb-1.18.0\db/skiplist.h(360): warning C4312: 'reinterpret_cast': conversion from 'int' to 'void *' of greater size (compiling source file leveldb-1.18.0\db\memtable.cc) [c:\leveldown\deps\leveldb\leveldb.vcxproj]

After I work up the strength to look at gyp config ill try and figure out the best way to manage the exclusion of the win/stdint.h and that bothersome warning then make a pull request.

[thunder7553]

I have the same problem after installing Visual Studio 2015. Is there anything new on this matter?

[No9]

So I couldn't work out how to determine the actual version of MSVC being used to compile when node-gyp runs under auto select.
i.e. I when build is ran without an explicit MSVC being added at the command line or as an ENV variable.
The above patch should work in the mean time but I will raise a ticket on there to see what those folks have to say.

[barbalex]

same problem here

this completely blocks building most of my node projects using npm i as they all contain pouchdb which installs leveldown :-(

Somehow this worked on my last windows machine but not on this brand new one.

I had to install VS2015 just for leveldown. If I understand correct, things would work with older versions of VS?

update:
Yep, VS2013 works. Please update your readme and point windows users to VS2013, explicitly not to VS2015.

[No9]

OK Deleted the previous message because I got it wrong and thought 1.4.3 was out
@ralphtheninja can we do a release and then @nolanlawson can bump 1.4.3

[nolanlawson]

@No9 We use Greenkeeper for PouchDB, so we'll get the new leveldown whenever someone releases it. 😃

[ralphtheninja]

OK Deleted the previous message because I got it wrong and thought 1.4.3 was out
@ralphtheninja can we do a release and then @nolanlawson can bump 1.4.3

Absolutely. I didn't think we needed a new release, sorry for the inconvenience :)

[ralphtheninja]

@No9 I'll take this opportunity to bump dependencies as well

[ralphtheninja]

1.4.3 released, awaiting @mafintosh to push the button for prebuilts

[No9]

OK I can still recreate the issue @barbalex is seeing on the 1.4.3 release.
Looks like this can be a little bit flaky
13e7034#diff-fe74db22d3e05f3e0fb5effc5b4df636R30

If the user sets the environment variable MSVS_VERSION to 2015 then it works as expected
@obastemur Do you have anything to add or should I just update the docs?

Thanks

[raymens]

I'm still having issues with the MSVS_VERSION set to 2015. Other native libraries are compiling just fine.

[ralphtheninja]

@raymens What OS are you running and which version of leveldown are you trying to install? There should be prebuilt binaries available for most OSes now.

[raymens]

@ralphtheninja W10 and trying to install latest (1.4.3)

[ralphtheninja]

@raymens I'm curious why you aren't getting one from https://github.com/Level/leveldown/releases/tag/v1.4.3 .. mind doing npm i leveldown --verbose and posting a gist?

[3tgame]

I use Win10 and VS2015, I have the same problem.
After downloaded the Prebuilt binaries, how to use the Prebuilt binaries?
some output of npm i leveldown --verbose are:

[ralphtheninja]

It seems there is a problem with leveldown-v1.4.3-node-v47-win32-x64.tar.gz which does exist. The error we get is unexpected end of file.

@No9 Any idea what's going on?

[BrokenR3C0RD]

I have the same problem as Raymens, but I'm on x86. My problem seems to arise because of no ia32 build existing. Pretty sure you could just use the x86 compilation, just have a copy named leveldown-v1.4.3-node-v47-win32-ia32.tar.gz
_EDIT:_ There is no ia32 or x86 build for 1.4.3 it seems. Is this on purpose?

The only purpose is that it was never built

Well, will this bug be fixed soon?

[ralphtheninja]

Well, will this bug be fixed soon?

Technically it's not a bug since you can compile the code yourself (assuming your environment is setup for this).

@No9 @mafintosh We had ia32 builds for 1.4.2 but it seems they aren't available for 1.4.3. Can anyone of you fix this?

[No9]

Sorry @ralphtheninja long story but my 32 builder has died and I won't have another win machine for a while.

[ralphtheninja]

Sorry @ralphtheninja long story but my 32 builder has died and I won't have another win machine for a while.

Ok! No worries :) Anyone that would like to help out with this?

[realjesset]

Having the same problems as others here, whenever I try npm install leveldown it gives me the same error which was showed by @raymens

[obastemur]

Sorry, somehow missed this one. I'm on it

[ralphtheninja]

@kde99 @thunder7553 @barbalex @raymens @TheGoGlider

Can you guys make sure you can compile the code now?

[raymens]

@ralphtheninja @obastemur yes, I've just compiled Leveldown@1.4.1. Thanks!

[ralphtheninja]

Released in 1.4.4

[raymens]

Oops, my bad. It is indeed 1.4.4 :)

[kraihn]

@ralphtheninja, I'm not sure who to contact, but the win32 prebuilt files haven't been uploaded to the release for 1.4.4 in GitHub. I'm having issues on my build server because it can't download non-existent files.

[ralphtheninja]

@kraihn I just built them. Try again please.

[kraihn]

@ralphtheninja, it's working again. Thanks!
