錯誤編譯朱古力分類

Question

我試圖編譯在OS X 10.10.5一個朱古力分類例如，使用下面的命令：

g++ -ggdb `pkg-config --cflags --libs opencv` -I /Users/SullyChen/caffe/include -I /usr/local/cuda/include -I /usr/local/Cellar/openblas/0.2.15/include -lboost_system -lglog -lprotobuf classification.cpp -o classification 

，但我得到了以下錯誤：

關於什麼問題的任何想法？

哦，我的天啊，我忘了鏈接Caffe ...那麼問題就解決了。

編輯：這是我在任何情況下使用的命令需要它

g++ -ggdb `pkg-config --cflags --libs opencv` -I /Users/SullyChen/caffe/include -I /usr/local/cuda/include -I /usr/local/Cellar/openblas/0.2.15/include -lboost_system -lglog -lprotobuf -L /Users/SullyChen/caffe/.build_release/lib -lcaffe classification.cpp -o classification
