c++ - Protobuf 链接器错误

Question

我正在尝试从目标文件创建一个可执行文件。这是我使用过的命令 -

g++ -Wall -O3 -std=c++0x -march=native -fopenmp -pthread -I/usr/local/include -DUSESSE -DUSEOMP -c -o timer.o timer.cpp
g++  model.pb.cc -Wall -O3 -std=c++0x -march=native -fopenmp -pthread -I/usr/local/include -DUSESSE -DUSEOMP  `pkg-config --cflags --libs protobuf` -c -o ffm-model.o
g++ -c ffm.cpp -Wall -O3 -std=c++0x -march=native -fopenmp -pthread -I/usr/local/include -DUSESSE -DUSEOMP -pthread -L/usr/local/lib -lprotobuf -lpthread -I. -o ffm.o 
g++ -Wall -O3 -std=c++0x -march=native -fopenmp -pthread -I/usr/local/include -DUSESSE -DUSEOMP -pthread -I/usr/local/include  -pthread -L/usr/local/lib -lprotobuf -lpthread -o ffm-train ffm-train.cpp ffm.o timer.o ffm-model.o

但我收到错误 -

知道我做错了什么吗？
