深度学习平台配置笔记_Caffe配置(1) matlab接口编译的坑(opencv3.3+CUDA9.0+matlab2017b+caffe)

本来caffe的配置用的makefile.config就很麻烦了，还要针对matlab接口进行配置，简直折磨人

首先用于配置的系统环境是ubuntu18.04 + cuda-9.0 + matlab2017b

坑一

经过一系列的配置后makefile会执行到
MEX matlab/+caffe/private/caffe_.cpp
进行matlab和caffe之间的编译
然后可能会发现报错如下:

caffe.pb.cc:(.text+0x4e4d3): undefined reference to google::protobuf::internal::WireFormatLite::ReadBytes(google::protobuf::io::CodedInputStream*, std::string*)'

最后的错误信息可能是:

Makefile:518: recipe for target 'matlab/+caffe/private/caffe_.mexa64' failed
make: *** [matlab/+caffe/private/caffe_.mexa64] Error 255

这是由于c++的编译器gcc的版本问题，由于之前为了配置caffe需要将编译器版本降至5.0以下，我选择了4.8。但是实际上这个操作会导致一系列的上述错误信息。

解决方法：
修改Makefile文件（注意不是Makefile.config）在CXXFLAGS += -MMD -MP这句后面填上CXXFLAGS += -std=c++11，并且维持之前的5.0以上的gcc的版本不用变化

这里会有个Warning，不用管它，不是Error就没问题啦

坑二

虽然前面或许会完美通过，但是当运行make mattest测试caffe的matlab接口时可能会失败，我的错误包含了以下的信息：

查询github和stackoverflow后经过漫长的尝试后，发现是OpenCV安装的时候配置了GDAL库及其依赖项，而且因为采用的OpenCV库的安装方式是sudo apt-get install的方式，我也不能设定是否关闭GDAL，所以我改用源码编译的方式重头安装OpenCV:

我先下载了OpenCV 3.3.1，cmake没问题，但是make的时候不幸的，又报错了:

再一次的查找，发现我的CUDA是9.0，但是貌似OpenCV 3.3.x只支持到CUDA8.0，所以才有如上的算法兼容性的错误。
所以我选择了不用CUDA 8.0，采用了OpenCV 3.4.1，这时顺利安装通过，然后重新make caffe的matlab接口然后 make mattest，完美通过！
