krb5-config - Man Page

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:

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