编译pycaffe. matcaffe和mattest出现的问题

1.make pycaffe 的错误

python/caffe/_caffe.cpp:10:31: fatal error: numpy/arrayobject.h: 没有那个文件或目录
compilation terminated.
Makefile:507: recipe for target ‘python/caffe/_caffe.so’ failed
make: * [python/caffe/_caffe.so] Error 1

解决方法：

sudo apt-get install python-numpy

sudo make pycaffe

然后 make clean

make pycaffe

2.make matcaffe

先打开Makefile。config中的Matalb，即去掉MATLAB_DIR := /usr/local/MATLAB/R2013b前面的#

然后编译出现问题

Makefile:518: recipe for target 'matlab/+caffe/private/caffe_.mexa64' failed

make: *** [matlab/+caffe/private/caffe_.mexa64] Error 255

解决方法：

在Makefile里面，大约第410行那一句话CXXFLAGS += -MMD -MP下面添加CXXFLAGS += -std=c++11，最后是这样
CXXFLAGS += -MMD -MP
CXXFLAGS += -std=c++11
然后在caffe根目录下make clean,make all

3.make mattest 出现

Invalid MEX-file '/home/gyn/caffe/matlab/+caffe/private/caffe_.mexa64':

/usr/local/MATLAB/R2013b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6:
version `GLIBCXX_3.4.20' not found (required by
/home/gyn/caffe/matlab/+caffe/private/caffe_.mexa64)

Error in caffe.set_mode_cpu (line 5)
caffe_('set_mode_cpu');

Error in caffe.run_tests (line 6)
caffe.set_mode_cpu();

解决方法：打开环境变量

vim ~/.bashrc

在文件最后一行加入下面两行代码

export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:/usr/local/cuda-8.0/lib64
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4:/usr/lib/x86_64-linux-gnu/libopencv_imgproc.so.2.4:/usr/lib/x86_64-linux-gnu/libopencv_core.so.2.4:/usr/lib/x86_64-linux-gnu/libstdc++.so.6:/usr/lib/x86_64-linux-gnu/libfreetype.so.6

然后 source ~/.bashrc

再编译就可成功通过
