[ADMB Users] How to use Autodif as a regular external C++ library?

[John Sibert]

I generally use make to compile and link AUTODIF applications. Here are 
examples of compiler and linker flags that are used in a linux 
environment. There are some application specific settings so, I  have 
also included simplified versions below the ------------

# make with "optimized" library without subscript checking
CFLAGS= -m64 -DTRUE=true -DFALSE=false -DVERCONS=1 -D__GNUDOS__ 
-DOPT_LIB -fpermissive -Wno-deprecated -I${ADMB_HOME}/include 
-I${JNIGRAPHICS_PATH} -I$(JAVA_HOME)/include 
-I$(JAVA_HOME)/include/linux -I/usr/include/libxml2 $(INCPATH)

LFLAGS= -L${JNIGRAPHICS_PATH} -L$(JAVA_HOME)/jre/lib/amd64/server 
-L${ADMB_HOME}/lib -ljnigraphics3 -ldf1b2o -ladmod -ladt -lado -ldf1b2o 
-ladmod -ladt -lads -lstdc++ -lm -lado -ladt -ldl -ljvm -lxml2 
-L/usr/share/pvm3/lib/LINUX64

# make with safe library for subscript checking
CFLAGS= -m64 -ggdb -DTRUE=true -DFALSE=false -DVERCONS=1 -D__GNUDOS__ 
-fpermissive -Wno-deprecated -I${ADMB_HOME}/include 
-I${JNIGRAPHICS_PATH} -I$(JAVA_HOME)/include 
-I$(JAVA_HOME)/include/linux -I/usr/include/libxml2 $(INCPATH)

LFLAGS= -ggdb -L${JNIGRAPHICS_PATH} -L$(JAVA_HOME)/jre/lib/amd64/server 
-L${ADMB_HOME}/lib -ljnigraphics3 -ldf1b2s -ladmod -ladt -lads -ldf1b2s 
-ladmod -ladt -lads -lstdc++ -lm -lads -ladt -ldl -ljvm -lxml2 
-L/usr/share/pvm3/lib/LINUX64

------------------

#make with "optimized" library without subscript checking
CFLAGS= -D__GNUDOS__ -DOPT_LIB -fpermissive -Wno-deprecated 
-I${ADMB_HOME}/include

LFLAGS= -L${ADMB_HOME}/lib -ldf1b2o -ladmod -ladt -lado -ldf1b2o -ladmod 
-ladt -lads -lstdc++ -lm -lado -ladt

# make with safe library for subscript checking and symbolic debugging
CFLAGS= -ggdb -D__GNUDOS__ -fpermissive -Wno-deprecated 
-I${ADMB_HOME}/include

LFLAGS= -ggdb -L${ADMB_HOME}/lib -ldf1b2s -ladmod -ladt -lads -ldf1b2s 
-ladmod -ladt -lads -lstdc++ -lm -lads

-------------------------

So (at least for this 3 year-old) example, the libraries you need are 
libadmod.a libadt.a libado.a (or libads.a) for the safe libraries. Note 
the order is important and they need to be linked twice (not sure why). 
Also, it appears that some the ADModel Builder libraries (libdf1b2o.a 
and libadmod.a) may be required to satisfy some references. Since these 
librararies are included in the ADMB distributions, there is no real 
downside to linking them into the application anyhow).

Please let us know how you make out.
