在 ubuntu lucid 和 maverick 上使用 thrift 0.7.0 编译 scribe2.2 时出错
我在 ubuntu 上编译 scribe 服务器时遇到以下错误。
In file included from store.cpp:27:
scribe_server.h:45: error: conflicting return type specified for ‘virtual scribe::thrift::ResultCode scribeHandler::Log(const std::vector<scribe::thrift::LogEntry, std::allocator<scribe::thrift::LogEntry> >&)’
../src/gen-cpp/scribe.h:18: error: overriding ‘virtual scribe::thrift::ResultCode::type scribe::thrift::scribeIf::Log(const std::vector<scribe::thrift::LogEntry, std::allocator<scribe::thrift::LogEntry> >&)’
store.cpp: In member function ‘virtual bool ThriftFileStore::openInternal(bool, tm*)’
我正在使用 scribe 2.2 和 thrift 0.7.0 安装thrift时没有出现错误。
我还在一篇文章中读到，使用旧版本的 thrift 时会遇到此错误。但我正在使用最新版本的thrift。
I am getting following error while compiling scribe server on ubuntu.
In file included from store.cpp:27:

store.cpp: In member function ‘virtual bool ThriftFileStore::openInternal(bool, tm*)’
I am using scribe 2.2 with thrift 0.7.0
There were no errors while installing thrift.
Also I read in one post that this error is encountered while using older versions of thrift. But I am using latest version of thrift.

看来是节俭出了问题。
解决方案：使用 thrift 稳定版本
照搬梁英毅的话：
“我认为这个问题与 thrift 最近的变化有关
（git 开发版本）。对于像这样的节俭代码片段：
枚举 X {
...
}
X foo();
thrift 用于为 foo 生成此原型：
X foo();
但现在它生成“X::type foo();”，导致错误
遇到。”

Seems to be a problem from thrift.
Solution: use thrift stable version
Copying literally Ying-Yi Liang words:
"I think this issue has something to do with a recent change in thrift
(the git dev version). For a thrift snippet like:
enum X {
...
}
X foo();
thrift used to generate this prototype for foo:
X foo();
but now it generates "X::type foo();", resulting in the error you
encountered."
