FAQ:Compiling 09

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)
