krb5-config - tool for linking against MIT Kerberos libraries

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

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

–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
_

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:

#+begin_quote

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

#+end_quote
