Troubleshooting

When building the examples ensure you have a clean $GOPATH. If you have checked out and built other libp2p repos then you may get errors similar to the one below when building the examples. Note that the use of the gx package manager is not required to run the examples or to use libp2p.

$:~/go/src/github.com/libp2p/go-libp2p-examples/libp2p-host$ go build host.go 
# command-line-arguments
./host.go:36:18: cannot use priv (type "github.com/libp2p/go-libp2p-crypto".PrivKey) as type "gx/ipfs/QmNiJiXwWE3kRhZrC5ej3kSjWHm337pYfhjLGSCDNKJP2s/go-libp2p-crypto".PrivKey in argument to libp2p.Identity:
        "github.com/libp2p/go-libp2p-crypto".PrivKey does not implement "gx/ipfs/QmNiJiXwWE3kRhZrC5ej3kSjWHm337pYfhjLGSCDNKJP2s/go-libp2p-crypto".PrivKey (wrong type for Equals method)
                have Equals("github.com/libp2p/go-libp2p-crypto".Key) bool
                want Equals("gx/ipfs/QmNiJiXwWE3kRhZrC5ej3kSjWHm337pYfhjLGSCDNKJP2s/go-libp2p-crypto".Key) bool

To obtain a clean $GOPATH execute the following:

> mkdir /tmp/libp2p-examples
> export GOPATH=/tmp/libp2p/examples
