[ADMB Users] DLLs

[dave fournier]

I thought it might be interesting to revisit this.  I used the example 
bimix.tpl from the manual.
I have attached the tpl file the data and the R script. this is for linux.
It is a crummy data example I just made up.

you create the cpp and htp files with the command

    tpl2cpp -dll bimix

Now you want to compile to a shared library.  This is a lot easier than 
it used to be.
first you need to rebuild admb-10.1 adding the -fPIC option for the 
compiler.

Here is my script to compile bimix.cpp and produce a shared library
named bimix.so


ADMB_HOME=/dave2/admb-10.1/build/admb-10.1-linux-gcc4.4.5-64bit/admb-10.1-linux-gcc4.4.5-64bit

g++  --shared  -fPIC -ggdb -w -fpermissive  -DUSE_LAPLACE -Dlinux 
-D__GNUDOS__ -o$1.so $1.cpp \
   -I. -I${ADMB_HOME}/include \
   -L${ADMB_HOME}/lib \
   -ladt -lads -ladmod -ldf1b2s -ladt -lads -ladmod -ldf1b2s \
   -ladt -lads -ladmod -ldf1b2s -ladt -lads -ladmod -ldf1b2s


under R this is loaded with the command

    dyn.load("bimix.so")


To run the example in R you type

    source("bimix.r")

and it all just works for me.


This all seems to work and it works when I call the routine twice as in 
the R script.

So maybe this is not too hard
