編譯 QBittorrent需要兩個步驟：

1、依賴庫的編譯
2、qBittorrent本身的編譯。

這裡概要講述第二步（很久以前做了第一步，現在忘了。過程很複雜）。

這裡使用的IDE環境是  QtCreator 2.5 ， 編譯使用的是VS2010的庫，所以QT版本是VS2010的版本。

依賴庫：

- libtorrent (v0.16.1)
- Qt (4.8.1)
- Boost (1.49.0)
- MSVC  2010

當依賴庫解決之後，就可以進行編譯了。

首先必須下載最新的qbittorrent原始碼，比如3.0.6的原始碼。

需要修改的幾個地方：

1、winconf.pri

2、winconf-msvc.pri

這裡 是各種依賴庫和標頭檔案的設定。 

下面是一個 例子：

winconf-msvc.pri:

RC_FILE = qbittorrent.rc

# Enable Wide characters
DEFINES += TORRENT_USE_WPATH

#Adapt the lib names/versions accordingly
CONFIG(debug, debug|release) {
  LIBS += libtorrentd.lib \
          libboost_system-vc90-mt-gd.lib \
          libboost_filesystem-vc90-mt-gd.lib \
          libboost_thread-vc90-mt-gd.lib
} else {
  LIBS += libtorrent.lib \
          libboost_filesystem-vc100-mt-1_47.lib \
          libboost_system-vc100-mt-1_47.lib \
          libboost_thread-vc100-mt-1_47.lib
}

LIBS += advapi32.lib shell32.lib
LIBS += libeay32.lib ssleay32.lib
LIBS += PowrProf.lib
 

下面是 winconf.pri:

# Adapt these paths on Windows


INCLUDEPATH += $$quote(D:/buildings/boost_1_47_0)
INCLUDEPATH += $$quote(D:/buildings/libtorrent-rasterbar-0.16.1/include)
INCLUDEPATH += $$quote(D:/buildings/openssl-1.0.1c/include)



#Point this to the boost lib folder
LIBS += $$quote(-LD:/buildings/openssl-1.0.1c/out32dll)
LIBS += $$quote(-LD:/buildings/libtorrent-rasterbar-0.16.1/bin/msvc-10.0/release/boost-source/encryption-openssl/geoip-static/link-static/threading-multi)
LIBS += $$quote(-LD:/buildings/boost_1_47_0/stage/lib)
