安装go-mtpfs时出现错误“未定义：sync.Pool”

Question

Running the command

sudo go get github.com/hanwen/go-mtpfs

I get the following output:

/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/fuse/bufferpool.go:41: undefined: sync.Pool
/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/fuse/bufferpool.go:54: undefined: sync.Pool
/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/fuse/server.go:44: undefined: sync.Pool
/usr/lib/go/src/pkg/github.com/hanwen/go-fuse/fuse/server.go:47: undefined: sync.Pool

What does this mean? How can I fix this?

Answer 1

The error message means that the go-fuse library uses sync.Pool, which was introduced in Go 1.3 (changes for that release: https://golang.org/doc/go1.3) and I suspect that the Go version you've installed on your system is older (e.g. on Debian stable (wheezy) it's 1.0.2). In order to use the go-fuse library you'll need to use a Go version of at least 1.3.
