15.5. Makefile Revisited

In "Section 15.1" on page 262, we used a Makefile to generate our agent. Now we just have to modify this Makefile to include our LAD-MIB code.

NETSNMP_VERSION = 5.2.1

config:
        cd $(BUILD_DIR); \
❸         export LDFLAGS="-lpq"; \
        ./configure --prefix=/opt/snmp \
❹                     --with-mib-modules="lad/ladProject"<../configure.input; \

        make
install:
        cd $(BUILD_DIR); \
        install

The changes are fairly minor. We've added two lines to the ...
