Undefined function troubleshooting

Technical Discussion
1

I get an undefined function error although the function exists in the code. How can I find the reason ? What methods can I use to troubleshoot this situation

I import:

    "github.com/jcmturner/gokrb5/v8/client"
    "github.com/jcmturner/gokrb5/v8/config"
    "github.com/jcmturner/gokrb5/v8/credentials"
    "github.com/jcmturner/gokrb5/v8/krberror"
    "github.com/jcmturner/gokrb5/v8/spnego"

and can use successfully client.NewWithPassword but not client.NewClientFromCCache which are both defined in gokrb5/client/client.go at master · jcmturner/gokrb5 · GitHub

I’m not sure what’s causing your problem, but I can build a project that uses both of the functions that you mention.

go.mod

module temp

go 1.23.4

require github.com/jcmturner/gokrb5/v8 v8.4.4

require (
	github.com/hashicorp/go-uuid v1.0.3 // indirect
	github.com/jcmturner/aescts/v2 v2.0.0 // indirect
	github.com/jcmturner/dnsutils/v2 v2.0.0 // indirect
	github.com/jcmturner/gofork v1.7.6 // indirect
	github.com/jcmturner/rpc/v2 v2.0.3 // indirect
	golang.org/x/crypto v0.6.0 // indirect
	golang.org/x/net v0.7.0 // indirect
)

main.go

package main

import (
	"fmt"

	"github.com/jcmturner/gokrb5/v8/client"
	"github.com/jcmturner/gokrb5/v8/config"
	"github.com/jcmturner/gokrb5/v8/credentials"
)

func main() {
	c1 := client.NewWithPassword("", "", "", &config.Config{})
	fmt.Println(c1)

	c2, err := client.NewFromCCache(&credentials.CCache{}, &config.Config{})
	fmt.Println(err)
	fmt.Println(c2)
}

$   go build main.go
$   ls -l

So it’s probably something silly. Perhaps a typo?

Oh yes something silly. the function name changed i.e. it lost Client in the name. :blush:
