I've been following the link (Guidelines for including TMB c++ code in an R package) to include a .cpp TMB model into my R package (fishmethods). I got it to work on Windows using a Makefile.win file with the code:

all: EP_likelihood.dll
        # Comment here preserves the prior tab
EP_likelihood.dll: EP_likelihood.cpp
        Rscript --vanilla -e "TMB::compile('EP_likelihood.cpp','-O0 -g',DLLFLAGS='')"
clean:
        rm -rf *.dll

and, in the Description file, setting

LinkingTo: TMB

and adding "TMB" to the *Imports:" line. Also, I added to the "Namespace" file

importFrom("TMB","MakeADFun","sdreport")

and

useDynLib(EP_likelihood).

I am able to build and install the package on Windows. I want to make the .cpp model portable across platforms because the updated package will be put on CRAN. I've been reading the "Writing R Extensions" manual particularly under "Writing Portable Packages" but I don't understand fully what I have to do (I am not a professional programmer). Would anyone have any suggestions or have an example that I could examine?

Thanks in advance.

Solved! I used TMBtools to create an example of a R package with CPP files and then copied the different statements I needed from the NAMESPACE, etc. files.
