My Little Modifications to the Windows Compilation WIKI:

[djal]

To compile Qbittorrent 3.0.2 with QT4.8.2, boost 1.51, libtorrent 0.16.3 or with lastest libtorrent svn and without zlib support.
==================================
(Im not a programmer, I tried to compile this just for fun.)



    Compilation Steps with msvc 10.0 compiler

We are building qBittorrent on Windows with msvc compiler instead of
MinGW. This choice was made because MinGW does not support wide
characters <http://www.mingw.org/wiki/wide_characters>. Msvc compiler
also generates smaller executables than MinGW.

  *

    •.Download and install Visual C++ 2010 Express
    <http://www.microsoft.com/visualstudio/e ... pp-express>
   

  *

    •.Download and install Qt binaries compiled with msvc
    <http://qt.nokia.com/downloads/windows-cpp-vs2010> (not compiled
    with MinGW) 

  *

    •.Add Msvc and Qt bin/ folders (C:\Qt\4.8.2\bin and C:\Program
    Files\Microsoft Visual Studio 10.0\VC\bin) to the PATH environment
    variable.

    (For example using windows 7: http://www.itechtalk.com/thread3595.html)

   

  *

    •.Create new folder  for download and extract sources. For example:
    D:\QBT_Project

  *

    •.Download Boost Jam
    <http://sourceforge.net/projects/boost/f ... p/download>
    32bits for 1.51 boost library (bjam) and Boost library
    <http://sourceforge.net/projects/boost/f ... p/download>
    1.51 and unzip them in D:\QBT_Project\

    You will got 2 new directories:

    D:\QBT_Project\bin

    and

    D:\QBT_Project\boost_1_51_0

  *

    •.Compile boost using the following command in a terminal:

    [ (bjam must be in the PATH):

    (For example using windows 7: http://www.itechtalk.com/thread3595.html)

    Edit PATH environment variable and ADD a  point to bjam.exe
    directory (you will need to close and reopen your terminal window
    after that)

    PATH = DONT CHANGE THE PREVIOUS ONE SIMPLE ADD THE
    FOLLOWING;D:\QBT_Project\bin 

    ]

    Open “Visual Studio Command Prompt”:

    Type:

    D: (Press Enter)

    cd D:\QBT_Project\boost_1_51_0 (Press Enter)

    Copy the following command in the “Visual Studio Command Prompt” and
    press Enter:

    bjam -q --with-filesystem --with-thread --toolset=msvc
    variant=release link=static runtime-link=shared



  *

    •.Define BOOST_ROOT environment variable and point to the boost
    source folder (you will need to close and reopen your terminal
    window after that) 

    (For example using windows 7: http://www.itechtalk.com/thread3595.html)

    BOOST_ROOT =  D:\QBT_Project\boost_1_51_0

  *

    •.Download lastest stable & recomended OpenSSL 32 bits
    <http://slproweb.com/download/Win32OpenSSL-1_0_1c.exe> and install it 

    (Default:  C:\OpenSSL-Win32 )

  *

    •.Copy OpenSSL include folder (C:\OpenSSL-Win32\include\openssl) to
    Msvc include/ folder (C:\Program Files\Microsoft Visual Studio
    10.0\VC\include) 

  *

    •.Download libtorrent 0.16.3
    <http://code.google.com/p/libtorrent/dow ... 6.3.tar.gz>
    and extract it (v0.14.10-v0.16.0svn are known to work)

    (Or you can try lastest Svn:
    http://libtorrent.svn.sourceforge.net/v ... ent/trunk/?
    <http://libtorrent.svn.sourceforge.net/v ... r>view=tar
    <http://libtorrent.svn.sourceforge.net/v ... /?view=tar>
    )

  *

    •.Compile libtorrent using the following command in a terminal: 

    Open “Visual Studio Command Prompt”:

    Type:

    D: (Press Enter)

    cd D:\QBT_Project\libtorrent-rasterbar-0.16.3(Press Enter)

    Copy the following command in the “Visual Studio Command Prompt” and
    press Enter:

bjam -q --without-python --toolset=msvc variant=release link=static
runtime-link=shared logging=none geoip=static encryption=openssl
dht-support=on boost=source define="BOOST_FILESYSTEM_VERSION=2"

  *

    •.Download a recent qBittorrent

      o

        •.GIT respository is located at
        git://github.com/cdumez/qBittorrent.git&nbsp;

      o

        •.Tarballs are available from sourceforge here
        <http://sourceforge.net/projects/qbittor ... z/download>
        (3.0.2)

      Download http://geolite.maxmind.com/download/geo ... oIP.dat.gz and extrac it (GeoIP.dat) in:
      D:\QBT_Project\qbittorrent-3.0.2\src\geoip

  *

    •.Download and install Qt Creator IDE 2.5.2 for Windows
    <http://get.qt.nokia.com/qtcreator/qt-cr ... -2.5.2.exe>

      o

        •.Configure Qt Creator to use Qt-msvc x86:

        Tools-->Options-->Build & Run-->QT versions should be QT 4.8.2
        qmake.exe

        Tools-->Options-->Build & Run-->Toolchains should be there MSVC
        10.0 x86

  *

    •.Start QtCreator IDE and load qBittorrent project file
    (qbittorrent.pro) in D:\QBT_Project\qbittorrent-3.0.2\

  * Make sure that in Projects--->Build settings--->Is in "Released Mode"

    •.Edit winconf.pri to point to the correct include and lib paths on
    your file system (boost, libtorrent, OpenSSL)

      o

        •.boost libs are generated in
        D:\QBT_Project\boost_1_51_0\stage\lib 

      o

        •.libtorrent lib is generated in
        D:\QBT_Project\libtorrent-rasterbar-0.16.3\bin\msvc-10.0\release\boost-source\encryption-openssl\geoip-static\link-static\threading-multi\

      o

        •.OpenSSL libs are located at C:\OpenSSL-Win32\lib\VC as a default 

    •.Build qBittorrent using QtCreator, it should compile fine!
  ( Build---->Rebuild All )
  qbittorrent.exe should be located in:
  D:\QBT_Project\qbittorrent-build-desktop-Qt_4_8_2_in_PATH__4_8_2__Release\src\release

Well, I hadnt compile for x64 but maybe someone could find it helpfull.
===========
To Crosscompile or generate 64 bits code with a 32 bits system:
Add to bjam the option:    address-model=64
===========
To Compile Qbittorrent x64:

*Compile QT4.8.2 or you can try it with this:
https://code.google.com/p/qt-msvc-installer/

*bjam.exe for 64 bits systems:
http://sourceforge.net/projects/boost/f ... p/download

*Install OpenSSL x64:
http://slproweb.com/download/Win64OpenSSL-1_0_1c.exe

* •.Configure Qt Creator to use Qt-msvc x64

        Tools-->Options-->Build & Run-->Toolchains should be there MSVC
        10.0 x64

*In winconf.pri:
# Adapt these paths on Windows to Point this to the x64 libs
*In winconf-msvc.pri:
# #Adapt the lib names/versions accordingly

Hopefully I dont forget anything

Actually this doesn't really matter since we're building on top of Qt and Boost, which support unicode regardless of the compiler.
I did build qBt with mingw64; works well, but requires poking around libtorrent code - mostly missing includes and __MINGW64__ ifdefs.
Regrading size: this has always been this way. -Os might be a better choice when using gcc; also -flto and -fuse-linker-plugin (/GL and /LTCG analogs of MSVC) are still bugged on windows.

Do not use prebuilt OpenSSL binaries; they require the MSVC 2008 runtime. Just build it yourself, it's very easy.

Someone should modify/update and apply this patch; it's bad not having the Version shown.  http://pastebin.com/7PbEaaUW

Lastly, someone should commit an installer script so that all the builders use it. Otherwise NSIS/Inno Setup installers are not compatible causing all kinds of problems.

As for MinGW, it would be very nice if someone included the needed patches in the repo. /GL /LTCG works perfectly fine here. -flto on the other almost never works right for me but I didn't try it with GCC 4.7.1 I use. Last time I tried it was with 4.7.0.

Should build fine under mingw32 (unless doing a static build, which is still bugged due to some strange args overflow https://code.google.com/p/libtorrent/is ... =1&q=mingw), mingw64 on the other hand needs some patches.

Last two patches are specific to qBt.

For anyone caring. If you sign up on Github you can edit/add any info in the wiki. I am currently updating the instructions on how to build on Windows.
