Boost::Python 静态联动
Boost::Python static linkage
我需要在我的项目中静态 link -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) 为“-shared”时，一切正常。但是，当 $(LINK) 是“-static”时，我会收到很多 linker 错误 "undefined symbol ..."，所有这些都与boost::python。这是其中的一些（完整列表对于 post 这里来说真的很庞大）：
