How to use levigo
问题
我想在Go语言中使用leveldb，并找到了levigo工具。
我尝试使用以下命令进行构建：
go get github.com/jmhodges/levigo
然后我遇到了错误：
/home/fun/workspace/study/leveldb/test/libleveldb.a(env_posix.o): In function `leveldb::(anonymous namespace)::StartThreadWrapper(void*)':
env_posix.cc:(.text+0x1e): undefined reference to `operator delete(void*)'
/home/fun/workspace/study/leveldb/test/libleveldb.a(env_posix.o): In function `leveldb::(anonymous namespace)::PosixEnv::NewLogger(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, leveldb::Logger**)':
env_posix.cc:(.text+0x10c): undefined reference to `operator new(unsigned long)'
/home/fun/workspace/study/leveldb/test/libleveldb.a(env_posix.o): In function `leveldb::(anonymous namespace)::PosixEnv::NewSequentialFile(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, leveldb::SequentialFile**)':
env_posix.cc:(.text+0x1e1): undefined reference to `operator new(unsigned long)'
env_posix.cc:(.text+0x1f7): undefined reference to `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
然后我尝试运行：
CGO_CFLAGS="-I/path/to/leveldb/include" CGO_LDFLAGS="-L/path/to/leveldb/lib" go get github.com/jmhodges/levigo
但是它没有起作用，并报告了几乎相同的错误。有人知道发生了什么以及如何修复吗？谢谢。

I want to use leveldb in go,and find the levigo tool
I try to build with the follow command
> go get github.com/jmhodges/levigo
Then I got failed with error:

then I try to run :
> CGO_CFLAGS="-I/path/to/leveldb/include" CGO_LDFLAGS="-L/path/to/leveldb/lib" go get github.com/jmhodges/levigo
it does not work and report almost the same error .
anybody know what happened and how to fix it?
thank you.
