# krb5-config.mit(1)

tool for linking against MIT Kerberos libraries

## NAME

krb5-config - tool for linking against MIT Kerberos libraries

## SYNOPSIS

**krb5-config** \[**--help** \| **--all** \| **--version** \| **--vendor** \| **--prefix** \| **--exec-prefix** \| **--defccname** \| **--defktname** \| **--defcktname** \| **--cflags** \| **--libs** \[*libraries*\]\]

## DESCRIPTION

krb5-config tells the application programmer what flags to use to compile and link programs against the installed Kerberos libraries.

## OPTIONS

- **--help**

  prints a usage message.  This is the default behavior when no options are specified.

- **--all**

  prints the version, vendor, prefix, and exec-prefix.

- **--version**

  prints the version number of the Kerberos installation.

- **--vendor**

  prints the name of the vendor of the Kerberos installation.

- **--prefix**

  prints the prefix for which the Kerberos installation was built.

- **--exec-prefix**

  prints the prefix for executables for which the Kerberos installation was built.

- **--defccname**

  prints the built-in default credentials cache location.

- **--defktname**

  prints the built-in default keytab location.

- **--defcktname**

  prints the built-in default client (initiator) keytab location.

- **--cflags**

  prints the compilation flags used to build the Kerberos installation.

- **--libs** \[*library*\]

  prints the compiler options needed to link against *library*. Allowed values for *library* are:

  | | |
  | --- | --- |
  | krb5 | Kerberos 5 applications (default) |
  | gssapi | GSSAPI applications with Kerberos 5 bindings |
  | kadm-client | Kadmin client |
  | kadm-server | Kadmin server |
  | kdb | Applications that access the Kerberos database |

## EXAMPLES

krb5-config is particularly useful for compiling against a Kerberos installation that was installed in a non-standard location.  For example, a Kerberos installation that is installed in **/opt/krb5/** but uses libraries in **/usr/local/lib/** for text localization would produce the following output:

```
shell% krb5-config --libs krb5
-L/opt/krb5/lib -Wl,-rpath -Wl,/opt/krb5/lib -L/usr/local/lib -lkrb5 -lk5crypto -lcom_err
```
