30.Dt BSD.SNMPMOD.MK 7
31.Os
32.Sh NAME
33.Nm bsd.snmpmod.mk
34.Nd building modules for
35.Xr bsnmpd 1
36.Sh SYNOPSIS
37.Fd ".include <bsd.snmpmod.mk>"
38.Sh DESCRIPTION
39The file
40.In bsd.snmpmod.mk
41simplifies the building of modules for the Begemot SNMP daemon,
42.Xr bsnmpd 1 .
43It provides some common functions for building a module and
44relies on
45.In bsd.lib.mk ,
46which is included by
47.In bsd.snmpmod.mk
48to actually build the shared library.
49.Pp
50The following
51.Xr make 1
52variables control the special functions:
53.Bl -tag -width ".Va EXTRAMIBDEFS"
54.It Va MOD
55The short name of the module.
56The name of the shared library will be
57.Pa snmp_${MOD}.so .
58There must exist a file
59.Pa ${MOD}_tree.def
60for compilation with
61.Xr gensnmptree 1
62which contains the definition of the MIB tree implemented by the module.
63.It Va EXTRAMIBDEFS
64A list of extra MIB definition files for
65.Xr gensnmptree 1 .
66This is optional.
67This file list is given to both calls to
68.Xr gensnmptree 1 No \(em
69the one that extracts the symbols in
70.Va XSYM
71from the MIB definitions and the one that
72generates the table with OIDs served by this module.
73.It Va EXTRAMIBSYMS
74A list of extra MIB definition files for
75.Xr gensnmptree 1 .
76This is optional.
77This file list is given only to the call to
78.Xr gensnmptree 1
79that extracts symbols from MIB definition files.
80It is useful if there are dependencies on other MIBs or for extracting global
81definitions for enumeration constants.
82.It Va XSYM
83A list of symbols to be extracted from the MIB definition files by
84.Xr gensnmptree 1 .
85This is optional.
86.It Va DEFS
87A list of MIB definition files to be installed.
88This is optional.
89.It Va BMIBS
90A list of textual MIBs to be installed.
91This is optional.
92.El
93.Pp
94Three files are automatically created from the MIB definition files and
95the
96.Va XSYM
97variable:
98.Bl -tag -width ".Va EXTRAMIBDEFS"
99.It Pa ${MOD}_tree.c
100This contains a table with the tree implemented by the module.
101It is automatically included into the
102.Va SRCS
103variable.
104.It Pa ${MOD}_tree.h
105This contains preprocessor defines for all the OIDs defined by the module
106and can be included in the module's source code.
107.It Pa ${MOD}_oid.h
108OID preprocessor definitions for all the symbols listed in
109.Va XSYMS .
110This is to be included into the module's source code.
