Same here. git bisect tells me, that aabeb7f585 breaks it. Before that go build runs just fine.

go get and go build cannot build libgit2 C code, which is embedded into git2go. Instead, there's a Makefile which takes care of building it and linking to it statically. See the README.md for the commands.

Works for me, too. Thanks!

BUT I get a warning:

# github.com/libgit2/git2go
ld: warning: directory not found for option '-L/Users/mattes/Developer/go/src/github.com/libgit2/git2go/vendor/libgit2/install/lib'
# github.com/libgit2/git2go
ld: warning: directory not found for option '-L/Users/mattes/Developer/go/src/github.com/libgit2/git2go/vendor/libgit2/install/lib'

(see full build log here https://gist.github.com/mattes/6624b09f1e67778b642b)

This warning appears even when I go run sth.go:

# command-line-arguments
ld: warning: directory not found for option '-L/Users/mattes/Developer/go/src/github.com/libgit2/git2go/vendor/libgit2/install/lib'
