NAME

bsd.snmpmod.mk – building modules for bsnmpd(1)

CONTENTS

SYNOPSIS


.include <bsd.snmpmod.mk>

DESCRIPTION

The file <bsd.snmpmod.mk> simplifies the building of modules for the Begemot SNMP daemon, bsnmpd(1). It provides some common functions for building a module and relies on <bsd.lib.mk>, which is included by <bsd.snmpmod.mk> to actually build the shared library.

The following make(1) variables control the special functions:
MOD
  The short name of the module. The name of the shared library will be snmp_${MOD}.so. There must exist a file ${MOD}_tree.def for compilation with gensnmptree(1) which contains the definition of the MIB tree implemented by the module.
EXTRAMIBDEFS
  A list of extra MIB definition files for gensnmptree(1). This is optional. This file list is given to both calls to gensnmptree(1) — the one that extracts the symbols in XSYM from the MIB definitions and the one that generates the table with OIDs served by this module.
EXTRAMIBSYMS
  A list of extra MIB definition files for gensnmptree(1). This is optional. This file list is given only to the call to gensnmptree(1) that extracts symbols from MIB definition files. It is useful if there are dependencies on other MIBs or for extracting global definitions for enumeration constants.
XSYM
  A list of symbols to be extracted from the MIB definition files by gensnmptree(1). This is optional.
DEFS
  A list of MIB definition files to be installed. This is optional.
BMIBS
  A list of textual MIBs to be installed. This is optional.

Three files are automatically created from the MIB definition files and the XSYM variable:
${MOD}_tree.c
  This contains a table with the tree implemented by the module. It is automatically included into the SRCS variable.
${MOD}_tree.h
  This contains preprocessor defines for all the OIDs defined by the module and can be included in the module's source code.
${MOD}_oid.h OID preprocessor definitions for all the symbols listed in XSYMS. This is to be included into the module's source code.

If you have a problem and you think awk(1) is the solution, then you have two problems.
