lanms-pybind的筆記

來自EAST的lanms的代碼

makefile的python路徑

CXXFLAGS = -I include  -std=c++11 -O3 $(shell /home/hlx2/anapy35/bin/python3-config --cflags)
LDFLAGS = $(shell /home/hlx2/anapy35/bin/python3-config --ldflags)

DEPS = lanms.h $(shell find include -xtype f)
CXX_SOURCES = adaptor.cpp include/clipper/clipper.cpp

LIB_SO = adaptor.so

$(LIB_SO): $(CXX_SOURCES) $(DEPS)
	$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC

clean:
	rm -rf $(LIB_SO)

hlx2@NLP:~/PycharmProjects/EAST-PVANET/lanms$ python3-config --cflags
-I/home/hlx2/anapy35/include/python3.5m -I/home/hlx2/anapy35/include/python3.5m -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes

-I/home/hlx2/anapy35/include/python3.5m：表示包含此目錄
-Idir

-O3：表示編譯器的優化選項

由於生成的.so文件和python的版本有關，所以要注意python3-config 的路徑。

find include -xtype f

$(LIB_SO): $(CXX_SOURCES) $(DEPS)
$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC
$(CXX_SOURCES) $(DEPS)：需要的文件
$(LIB_SO)：要生成的文件名
$(CXX) -o $@ $(CXXFLAGS) $(LDFLAGS) $(CXX_SOURCES) --shared -fPIC：要執行的命令
命令前面是tab

生成方法

sudo make
