33.Os
34.Sh NAME
35.Nm bsd.snmpmod.mk
36.Nd building modules for
37.Xr bsnmpd 1
38.Sh SYNOPSIS
39.Fd ".include <bsd.snmpmod.mk>"
40.Sh DESCRIPTION
41The file
42.In bsd.snmpmod.mk
43simplifies the building of modules for the Begemot SNMP daemon,
44.Xr bsnmpd 1 .
45It provides some common functions for building a module and
46relies on
47.In bsd.lib.mk ,
48which is included by
49.In bsd.snmpmod.mk
50to actually build the shared library.
51.Pp
52The following
53.Xr make 1
54variables control the special functions:
55.Bl -tag -width ".Va EXTRAMIBDEFS"
56.It Va MOD
57The short name of the module.
58The name of the shared library will be
59.Pa snmp_${MOD}.so .
60There must exist a file
61.Pa ${MOD}_tree.def
62for compilation with
63.Xr gensnmptree 1
64which contains the definition of the MIB tree implemented by the module.
65.It Va EXTRAMIBDEFS
66A list of extra MIB definition files for
67.Xr gensnmptree 1 .
68This is optional.
69This file list is given to both calls to
70.Xr gensnmptree 1 \(em
71the one that extracts the symbols in
72.Va XSYM
73from the MIB definitions and the one that
74generates the table with OIDs served by this module.
75.It Va EXTRAMIBSYMS
76A list of extra MIB definition files for
77.Xr gensnmptree 1 .
78This is optional.
79This file list is given only to the call to
80.Xr gensnmptree 1
81that extracts symbols from MIB definition files.
82It is useful if there are dependencies on other MIBs or for extracting global
83definitions for enumeration constants.
84.It Va XSYM
85A list of symbols to be extracted from the MIB definition files by
86.Xr gensnmptree 1 .
87This is optional.
88.It Va DEFS
89A list of MIB definition files to be installed.
90This is optional.
91.It Va BMIBS
92A list of textual MIBs to be installed.
93This is optional.
94.El
95.Pp
96Three files are automatically created from the MIB definition files and
97the
98.Va XSYM
99variable:
100.Bl -tag -width ".Va EXTRAMIBDEFS"
101.It Pa ${MOD}_tree.c
102This contains a table with the tree implemented by the module.
103It is automatically included into the
104.Va SRCS
105variable.
106.It Pa ${MOD}_tree.h
107This contains preprocessor defines for all the OIDs defined by the module
108and can be included in the module's source code.
109.It Pa ${MOD}_oid.h
110OID preprocessor definitions for all the symbols listed in
111.Va XSYMS .
112This is to be included into the module's source code.
