打开caffe/CMakeLists.txt

caffe_option(BUILD_matlab "Build Matlab wrapper" OFF IF UNIX OR APPLE)

改为

caffe_option(BUILD_matlab "Build Matlab wrapper" ON IF UNIX OR APPLE)

打开caffe/cmake/Modules/FindMatlabMex.cmake

find_program(Matlab_mex NAMES mex mex.bat HINTS ${Matlab_DIR} PATH_SUFFIXES bin NO_DEFAULT_PATH)

find_program(Matlab_mexext NAMES mexext mexext.bat HINTS ${Matlab_DIR} PATH_SUFFIXES bin NO_DEFAULT_PATH)

改为

find_program(Matlab_mex NAMES mex mex.bat HINTS /usr/local/matlab2015b PATH_SUFFIXES bin NO_DEFAULT_PATH)

find_program(Matlab_mexext NAMES mexext mexext.bat HINTS /usr/local/matlab2015b PATH_SUFFIXES bin NO_DEFAULT_PATH)

make报错
CMake Error at cmake/Utils.cmake:357(message):
Logic error. Need to update cmake script
Call Stack (most recent call first):
matlab/CMakeList.txt:38 (caffe_parse_linker_libs)

解决方法：
将caffe/cmake/Utils.cmake 357行

message(FATAL_ERROR "Logic error. Need to update cmake script")
1
改为

message(WARNING "Logic error. Need to update cmake script")

错误：/home/wangfeng/sphereface-master/tools/caffe-sphereface/matlab/+caffe/private/caffe_.cpp:18:27: fatal error: caffe/caffe.hpp: 没有那个文件或目录
/home/wangfeng/sphereface-master/tools/caffe-sphereface/include/caffe/util/device_alternate.hpp:34:23: fatal error: cublas_v2.h: 没有那个文件或目录
解决方法：
打开caffe/build/matlab/CmakeFiles/matlab.dir/build.cmake
大约61行
加入caffe/include路径
加入/usr/local/cuda/include路径

错误：Invalid MEX-file ‘…/caffe/matlab/+caffe/private/caffe_.mexa64’:libcaffe.so.1.0.0:无法打开共享对象文件：没有那个文件或目录
把caffe/build/lib添加到环境变量

错误：Invalid MEX-file ‘…/caffe/matlab/+caffe/private/caffe_.mexa64’:
/usr/local/matlab2015b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version ‘CXXABI_1.3.9’ not found (required by /home/wangfeng/anaconda2/lib/libhdf5_cpp.so.101)
原因是matlab自带的glibc库版本过低
解决方法：将高版本的libstdc++.so.6链接到matlab下的libstdc++.so.6
但是服务器下没有权限链接高版本的libstdc++.so.6
在matlab窗口中执行system('echo $LD_LIBARARY_PATH')，发现matlab环境中matlab路径在前面，而anaconda2/lib路径在后面
发现caffe/matlab/demo/classification_demo.m里面提到

% You may need to do the following before you start matlab:
% $ export LD_LIBRARY_PATH=/opt/intel/mkl/lib/intel64:/usr/local/cuda-5.5/lib64
% $ export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

解决方法：

export LD_PRELOAD=/home/wangfeng/anaconda2/lib/libstdc++.so.6
