[SOLVED] TMB c++ code in R package and CRAN checks

TMB c++ code in R package and CRAN checks

I am working on an R package to include c++ templates created in TMB. Using the helpful guidelines shared in this suggestion, I managed to come a very long way.

At the moment, I'm using 2 c++ templates ("kglmer.cpp" and "nglmer.cpp") and the following Makefile.win (and equivalent Makefile) to create the dll's:

all: kglmer.dll nglmer.dll

kglmer.dll: kglmer.cpp
    Rscript --vanilla -e "TMB::compile('kglmer.cpp', '-O1 -g',DLLFLAGS='')"
nglmer.dll: nglmer.cpp
    Rscript --vanilla -e "TMB::compile('nglmer.cpp', '-O1 -g',DLLFLAGS='')"

clean:
    rm -rf *o

However, when running CRAN checks (using devtools::check()), I receive the following warning:

checking if this is a source package ...
     Subdirectory '/src' contains apparent object files/libraries
     kglmer.dll nglmer.dll
Object files/libraries should not be included in a source package.

The issue seems to be related to not properly cleaning the src folder. Do you have any suggestions on how to proceed?

Solution

Theclean targets should match the all target, i.e. in Makefile.win you should have

clean:
    rm -rf *.dll
