c++ - thrift & boost - 有初始化器但类型不完整

Question

我目前正在使用 Thrift 示例:Click

我创建的以下测试代码无法编译。

#include <thrift/transport/TSocket.h>
#include <thrift/transport/TBufferTransports.h>
#include <thrift/protocol/TBinaryProtocol.h>

using namespace apache::thrift;
using namespace apache::thrift::protocol;
using namespace apache::thrift::transport;

int main(int argc, char **argv) {
    boost::shared_ptr<TSocket> socket(new TSocket("localhost", 9090));
    boost::shared_ptr<TTransport> transport(new TBufferedTransport(socket));
    boost::shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport));

    return 0;
}

尝试编译时，出现以下异常:

我仔细检查过，boost 和 thrift 都已正确安装在我的系统上。 (ArchLinux x64)。这个错误的原因是什么？

Answer 1

#include <boost/shared_ptr.hpp>

也许它是在 thrift 的 header 中的某处预先声明的？
