Question

我想在go中使用leveldb，找到levigo工具我尝试使用follow命令构建

去获取github.com/jmhodges/levigo

然后我失败了，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**)':

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

它不起作用并报告几乎相同的错误。有谁知道发生了什么以及如何解决它？谢谢。

这是我的levigo安装：

$ uname -a
Linux peter 3.8.0-27-generic #40-Ubuntu SMP Tue Jul 9 00:17:05 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
$ go version

$ go get -v github.com/jmhodges/levigo
github.com/jmhodges/levigo (download)

$

如果运行这些命令，会得到什么输出？
