symbol lookup error: git2go_play: undefined symbol: git_reference_is_tag

fedora: 20
go:1.1

I have a issue with the Reference.IsTag() method which appears to be unimplemented but Reference.IsBranch() works. I have checked the code base in both libgit2 and git2go and they bothe appear to be implemented the same.

git2go_play --repo ~/git/testrepo/

git2go_play: symbol lookup error: git2go_play: undefined symbol: git_reference_is_tag

Sample code

package main

import (
    "github.com/libgit2/git2go"
    "fmt"
    "log"
    "flag"
)

func main(){
    repoPath := flag.String("repo", "~/git/testrepo", "path to the git repository")
    flag.Parse()

    repo, err := git.OpenRepository(*repoPath)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(repo)
    refs, err := repo.NewReferenceIterator()
    if err != nil {
        log.Fatal(err)
    }
    for ref := range refs.Iter() {
        msg := ""
        if ref.IsBranch() {
            msg += "IsBranch"
        }
        if ref.IsTag() {
            msg += "IsTag"
        }
        if ref.IsRemote(){
            msg += "IsRemote"
        }

        fmt.Printf("%s: %s\n", msg, ref.Name())

    }
}

That version of the library does have that function. Have you double-checked your library load paths? Does ldd git2go_play show where you installed this version of the library?

sorry, my fault. Fedora doesn't look in /usr/local/lib/ by default so it was picking up the fedora packaged version. I uninstalled the fedora libgit2 rpms and fixed my ld configs so that it would find the library I compiled from source.

sudo yum -y remove libgit2 libgit2-devel

sudo "echo /usr/local/lib > /etc/ld.so.conf.d/local-libs.conf"
sudo ldconfig
