[英]Apache thrift undefined reference to apache::thrift::server::TNonblockingServer
I'm trying to compile a piece of code that creates a TNonblockingServer and I get the following compile error. 我正在尝试编译一段创建TNonblockingServer的代码,我得到以下编译错误。 Any idea what's wrong?
知道什么是错的吗?
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()'
I performed the steps outlined here while installing thrift. 我在安装thrift时执行了这里列出的步骤。 http://thrift.apache.org/docs/install/os_x/
http://thrift.apache.org/docs/install/os_x/
Here's my makefile 这是我的makefile
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
As pointed out by Dmitry, if we add -lthriftnb
to compiling command, it solves the problem. 正如Dmitry所指出的,如果我们将
-lthriftnb
添加到编译命令中,它就可以解决问题。 These missing references are found in libthriftnb.so This file has references to libevent. 这些缺少的引用可以在libthriftnb.so中找到。这个文件引用了libevent。 So I had to include
-levent
to compiling command. 所以我不得不包括
-levent
来编译命令。 Without -levent
linker generates multiple error messages. 没有
-levent
链接器会生成多个错误消息。 Some of the messages are as follows - 一些消息如下 -
/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'
