How can I compile the project to use static linking?

For totally static net-snmp executables, use

       configure --with-ldflags=-Bstatic

To compile your application with static libraries (eg for easier debugging), and to link to a non-installed build directory, try the following Makefile fragment:

 NETSNMPDIR=/usr/local/build/snmp/full-clean-cvs-V5-1-patches
 NETSNMPCONFIG=$(NETSNMPDIR)/net-snmp-config
NETSNMPBASECFLAGS := $(shell $(NETSNMPCONFIG) --base-cflags) NETSNMPINCLUDES := $(shell $(NETSNMPCONFIG) --build-includes $(NETSNMPDIR)) # base flags after build/src include, in case it has /usr/local/include NETSNMPCFLAGS=$(NETSNMPINCLUDES) $(NETSNMPBASECFLAGS)
NETSNMPBASELIBS := $(shell $(NETSNMPCONFIG) --base-agent-libs) NETSNMPEXTLIBS := $(shell $(NETSNMPCONFIG) --external-agent-libs) NETSNMPLIBDIRS := $(shell $(NETSNMPCONFIG) --build-lib-dirs $(NETSNMPDIR)) NETSNMPLIBDEPS := $(shell $(NETSNMPCONFIG) --build-lib-deps $(NETSNMPDIR)) LIB_DEPS=$(NETSNMPLIBDEPS) LIBS=$(NETSNMPLIBDIRS) -Wl,-Bstatic $(NETSNMPBASELIBS) -Wl,-Bdynamic $(NETSNMPEXTLIBS)
STRICT_FLAGS = -Wall -Wstrict-prototypes CFLAGS=-I. $(NETSNMPCFLAGS) $(STRICT_FLAGS)

This replaces the standard Makefile section, which will used installed libraries:

 NETSNMPCONFIG=net-snmp-config
# uncomment this if you have GNU make #NETSNMPCFLAGS := $(shell $(NETSNMPCONFIG) --base-cflags) #NETSNMPLIBS := $(shell $(NETSNMPCONFIG) --agent-libs) NETSNMPCFLAGS=`$(NETSNMPCONFIG) --base-cflags` NETSNMPLIBS=`$(NETSNMPCONFIG) --agent-libs`
LIBS=$(NETSNMPLIBS)
