我正在尝试编译一段创建 TNonblockingServer 的代码，但出现以下编译错误。知道有什么问题吗？

something_server.cpp:(.text+0x1ad): undefined reference to `apache::thrift::server::TNonblockingServer::serve()'
something_server.cpp:(.text+0x1c1): undefined reference to `apache::thrift::server::TNonblockingServer::~TNonblockingServer()'
something_server.cpp:(.text+0x280): undefined reference to `apache::thrift::server::TNonblockingServer::~TNonblockingServer()'

我在安装 Thrift 时执行了此处列出的步骤。 http://thrift.apache.org/docs/install/os_x/

这是我的生成文件

GEN_SRC := Something.cpp something_constants.cpp something_types.cpp
GEN_OBJ := $(patsubst %.cpp,%.o, $(GEN_SRC))

THRIFT_DIR := /usr/local/include/thrift
BOOST_DIR := /usr/local/include

INC := -I$(THRIFT_DIR) -I$(BOOST_DIR)

.PHONY: all clean

all: something_server something_client

%.o: %.cpp 
    $(CXX) -Wall -DHAVE_INTTYPES_H -DHAVE_NETINET_IN_H $(INC) -c $< -o $@ 

something_server: something_server.o $(GEN_OBJ)
    $(CXX) $^ -o $@ -L/usr/local/lib -lthrift 

something_client: something_client.o $(GEN_OBJ)
    $(CXX) $^ -o $@ -L/usr/local/lib -lthrift 

clean: 
    $(RM) *.o something_server something_client

正如 Dmitry 所指出的，如果我们添加-lthriftnb到编译命令，它可以解决问题。这些缺失的引用可在 libthriftnb.so 中找到。此文件包含对 libevent 的引用。所以我不得不包括-levent编译命令。没有-levent链接器会生成多个错误消息。部分讯息如下 -

/usr/local/lib/libthriftnb.so: undefined reference to `event_set'
/usr/local/lib/libthriftnb.so: undefined reference to `evbuffer_new'
/usr/local/lib/libthriftnb.so: undefined reference to `evhttp_free'
