# krb5-config

## 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
