KRB5-CONFIG(1)

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
