[Windows] Fess's builds (64-bit): LevelDB, DirectX, etc.

[miner65536]

Hi Fess,
Really nice work, this runs really quickly on an i5 laptop with win8 (seems to rarely drop below 60hz).
Can you tell me which versions of the components you've used and where to get them from? I would like to work on my own win64 minetest build with everything enabled, IE curl, JIT, fonts & sound?
I've done a quick win32 build with vs11, but it barely works, I followed the short (and presumably out of date) compile guide in the minetest source tree but I had to fix-up too much to have confidence in it. I switched everything off that I could but still got compile errors, specifically irrilicht 1.7.1 had an ambiguous swap<> defined that confused vs11, I had to ignore libcmt to get it to link too. My exe bombs out really quickly & even if it was stable without a JIT it will never be up to full speed.
Any help with the win64 build will be greatly appreciated.

Cheers,
Rob.

You sound like somebody who could be of great assistance to Fess should he need it.

If you have the skill to do so, you could try your hand at improving Minetest's compatibility with DirectX 9 sometime.

Add a setting for HighPrecisionFPU (fixes #763)... What effect does this have on DirectX 9? It sounds like it would make it smoother, but does it?

New build commit 439079cad8, still have the same problem with localization.
http://yadi.sk/d/AYB_NZUf8RoHW
I'm using Irrlicht 1.8, curl 7.31, luajit 2.0.1 compiled from sources from official sites, also all other libs with latest stable versions. For some frequently updated libs(like curl) not always latest, but that works without causing problems:) Compiling with VS10, Win 7 x64, also default libcmt ignored in settings.

With this build, the public server list doesn't show up (the favorite server list shows up in its place.) It looks like curl is one of those libraries that needs to constantly be updated, unfortunately.

I've just forgot to enable curl in that build in config file.

Thank you for this build.

RealBadAngel was in the #minetest chat room recently. If you wish to speak with him or anybody else there, you are able to chat there.

What is LevelDB used for in Minetest?

[jojoa1997]

It allows for a bigger minetest world file I think.

[PilzAdam]

What is LevelDB used for in Minetest?

sqlite has problems with worlds bigger than 4 GiB (singleplayer wont reach that limit, but big servers can reach it), the world gets corrupted in some places. leveldb doesnt have this problem, so big servers will probably use it.
Also some people say that its faster, but I dunno if that is correct.

There is one commit that says that it doesn't work with Windows operating systems, which means that servers that want to use it can't use those.

Seriously, who would use Windows for hosting servers?
Also the Add message that LevelDB is not supported on Windows is not relevant anymore since the Use system-wide LevelDB instead of bundled one removes the LevelDB source code.
You can build Minetest for Windows with LevelDB if you have a library and the header files

Hosting Servers means having a dedicated/virtual server that runs 24/7 to host something all the time
I've also succeeded in building LevelDB for Windows.

If Fess asks you how to do this, will you tell him so that he can successfully make 64-bit builds with it?

New build with latest commit 3c4734d69a:
[spoiler="Changelog"]

• Change mainmenu texture handling + small misc changes
  Texture names must now be escaped in formspec elements image[],
  background[], image_button[], image_button_exit[].
  Instead of special-case handling of texture loading (and unloading
  which was missing) in guiFormSpecMenu.cpp, use the newly created
  ISimpleTextureSource interface which is a minimal subset of
  ITextureSource. There is an implementation of this interface
  used by GUIEngine (MenuTextureSource).
  Fix an off-by-one bug in unescape_string; it caused requests for a texture called "\0".
• Fix hotbar padding at bottom
• Add offset to automatic_face_movement_dir
• Fix bug: texture pack not overriding default menu textures

Does this have LevelDB support? Is there any way that I could tell?

Try migrating a world from sqlite3 to leveldb, if that works there is leveldb support.

[Fess]

Does this have LevelDB support? Is there any way that I could tell?

No, its have no. I have tried to compile LevelDB from sfan5 link https://github.com/bitcoin/bitcoin/blob/master/src/leveldb/WINDOWS.md but it has no *.sln or *.vcxproj file, so provided instruction in .md file doesn't affect. Also i've tried to make sln for visual studio from sources, following instructions provided for windows on its sourceforge page but that solution leads to many errors while compiling, some of them was fixed but after i recieved errors at linking stage.

I have it for 32bit if you need it:
http://sfan5.pf-control.de/libleveldb-1.12-win32.zip
You can mix 64bit builds with 32bit libs freely if you use the .dll

Thx, i tried to use this library, but the problem is that its contains linux style static library(*.a), that cannot be used by visual studio( Its possible to use dll functions with explicit linking, but its need manually adds all of them to minetest sources, thats also needs much time. So i will try to find the way to compile leveldb from sources to get *.lib for implicit linking of dll library. Maybe it is some alternative ways that you can suggest me? ( I know that its possible to compile complete minetest with mingw64, but thats not a decision because mingw build are without native directx support)

1) *.a is not linux specific
2) This may help

Yep, first that i tried to set it up like at that link, and i have recieved error j:\Games\minetest\leveldb\lib\libleveldb.a : warning LNK4003: invalid library format; library ignored. As a read that way is suitable only for C libs, not for C++(
Also i found outdated port of LevelDB (from 2011 year) for visual studio, its compiles but when i try to use it in minetest i've recieve errors at linking stage
