OpenBR编译

我是在OS X上编译OpenBR的，另外在云主机上编译Qt这种东西简直太坑了！

OpenBR有一个人脸比对的功能，效果还可以，主要是在标数据时候用。

编译过程基本遵循如下：

1. Download and install the latest "XCode" and "Command Line Tools" from the Apple Developer Downloads page.

2. Download CMake 3.0.2

       $ cd ~/Downloads
       $ tar -xf cmake-2.8.11.2.tar.gz
       $ cd cmake-2.8.11.2
       $ ./configure
       $ make -j4
       $ sudo make install
       $ cd ..
       $ rm -rf cmake-2.8.11.2*
   

3. Download OpenCV 2.4.11

   $ cd ~/Downloads
   $ unzip opencv-2.4.11.zip
   $ cd opencv-2.4.11
   $ mkdir build
   $ cd build
   $ cmake -DCMAKE_BUILD_TYPE=Release ..
   $ make -j4
   $ sudo make install
   $ cd ../..
   $ rm -rf opencv-2.4.11*
   

4. Download and install Qt 5.4.1

5. Create a GitHub account, follow their instructions for setting up Git.

   $ git clone https://github.com/biometrics/openbr.git 

   $ cd openbr 

   $ git checkout 0.5   官方给出的是错的，此处应为：git checkout master

   $ git submodule init 

   $ git submodule update

6. Build OpenBR!

   $ mkdir build # from the OpenBR root directory 

   $ cd build 

   $ cmake -DCMAKE_PREFIX_PATH=~/Qt/5.4.1/clang_64 -DCMAKE_BUILD_TYPE=Release ..  应为：cmake -DCMAKE_PREFIX_PATH=~/Qt5.4.1/5.4/clang_64 -DCMAKE_BUILD_TYPE=Release  -DBR_EMBEDDED=True -DBR_WITH_STASM4=False ..

   $ make -j4 

   $ sudo make install

7. Hack OpenBR!

   1. Open Qt Creator IDE

      $ open ~/Qt/Qt\ Creator.app   应为：  open ~/Qt5.4.1/Qt\ Creator.app/

   2. From the Qt Creator "File" menu select "Open File or Project...".

   3. Select "openbr/CMakeLists.txt" then "Open".
   4. Browse to your pre-existing build directory "openbr/build" then select "Continue".
   5. Select "Run CMake" then "Done".
   6. You're all set! You can find more information on Qt Creator here if you need it.

8. (Optional) Test OpenBR!

   $ cd openbr/scripts
   $ ./downloadDatasets.sh
   $ cd ../build
   $ make test
   

9. (Optional) Package OpenBR!

   $ cd openbr/build
   $ sudo cpack -G TGZ
   

10. (Optional) Build OpenBR documentation!

Need to remake this step with the new docs!
