bundler安装（无法使用内置sift）

https://github.com/TheFrenchLeaf/Bundler

1. 安装cmake

2. 安装bundler

   mkdir build
   cd build
   cmake ..
   make 
   
   apt-get install imagemagick
   

   Linux => use makefile in program/main or Cmake.
         => Note the fact that the compilation will use the following resident libraries :
            - jpeg
            - lapack blas gfortran (included in most lapack distibution)
            - sometimes atlas.
   
   => CMAKE USAGE :
   Go to the extracted archive path. 
   $ mkdir Output
   $ cd Output
   $ cmake -G "CodeBlocks - Unix Makefiles" ..
   $ make
   => Your binaries will be in Output/src !
   
   apt-get install -y libjpeg-dev liblapack-dev libblas-dev gfortran libatlas-base-dev

     • 解决：

     Resolved by adding -lblas to the end of:
     
     src/CMakeFiles/Bundle2PMVS.dir/link.txt
     src/CMakeFiles/Bundler.dir/link.txt
     src/CMakeFiles/RadialUndistort.dir/link.txt
     

3. 修改

   ~~MATCHKEYS=$BASE_PATH/Output/src/KeyMatchFull
   BUNDLER=$BASE_PATH/Output/src/Bundler~~
   MATCHKEYS=$BASE_PATH/build/src/KeyMatchFull
   BUNDLER=$BASE_PATH/build/src/Bundler
   

   chmod -R a+x bin/*

4. bin/sift无法运行

   linux内核版本问题？搁置。。。

   ../bin/sift 
   bash: ../bin/sift: No such file or directory
