Boost :: Python静态链接

Question

我需要在项目中静态链接-lboost_python 。 这是我的Makefile：

CC=g++
override CFLAGS+=-c -std=c++11 -Wall -Wextra -Werror
override LFLAGS+=-lboost_python -lpthread -lboost_filesystem -lboost_system -lboost_thread -lcrypto

client: clientmain.o client.o ccommand.o
    $(CC) $(LINK) ../build/datatype.o ../build/utility.o build/clientmain.o build/client.o build/ccommand.o -o \
        build/mylib.so $(LFLAGS)
clientmain.o: main.cpp
    $(CC) $(CFLAGS) -fPIC main.cpp -o build/clientmain.o
client.o: cclient.cpp
    $(CC) $(CFLAGS) -fPIC cclient.cpp -o build/client.o
ccommand.o: ccommand.cpp
    $(CC) $(CFLAGS) -fPIC ccommand.cpp -o build/ccommand.o  

当$（LINK）被“共享”时，一切正常。 但是，当$（LINK）是“ -static”时，我得到了很多链接器错误“ undefined symbol ...”，所有这些都与boost :: python相关。 以下是其中一些（完整列表的确很大，可以在此处发布）：

我的Makefile有什么问题？

缺少的符号肯定来自libpython，所以您可以尝试添加-lpython2.7或要使用的任何python版本。
