| 15 | dnl This file provides local macros for packages which use Kerberos |
|---|
| 16 | dnl version 4. The public macros are: |
|---|
| 17 | dnl ATHENA_KRB4 |
|---|
| 18 | dnl Sets KRB4_LIBS and defines HAVE_KRB4 if krb4 used. |
|---|
| 19 | dnl ATHENA_KRB4_REQUIRED |
|---|
| 20 | dnl Generates error if krb4 not found. Sets KRB4_LIBS |
|---|
| 21 | dnl otherwise. (Special behavior because krb4 libraries |
|---|
| 22 | dnl may be different if using krb4 compatibility libraries |
|---|
| 23 | dnl from krb5.) |
|---|
| 24 | dnl |
|---|
| 25 | dnl All of the macros may extend CPPFLAGS and LDFLAGS to let the |
|---|
| 26 | dnl compiler find the requested libraries. Put ATHENA_UTIL_COM_ERR |
|---|
| 27 | dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there |
|---|
| 28 | dnl is a com_err library in the AFS libraries which requires -lutil. |
