Hello,
Short version: Is it possible to instruct the code generator in
`compileAttributes` to source local header files when generating
RcppExports.cpp?
Long version: I'm trying to crib from the Dirk's examples in his recent
UCB talk examples about function pointers
(http://dirk.eddelbuettel.com/papers/rcpp_booth_uofc_oct2013-part2.pdf).
In it, he uses a `typedef` to define the type of his function call. This
is all great if using `sourceCpp` to slurp in the file directly, but I'm
getting errors when compiling a package. I'd like to use attributes to
export my functions at both the R level and as the target of function
pointers, but this may be incompatible with attributes, at least at some
level.
My (perhaps naive) attempts are giving errors about my `funcPtr` type
not being defined. I've tried moving this definition to a header file,
but even with `//[[Rcpp::depends(myheader)]]` or
`\\[Rcpp::depends(myheader.h)]]`, the generated RcppExports.cpp file
does not include `myheader.h`.
My (non-working) code can be found at:
https://github.com/markmfredrickson/RItools/blob/ri-rcpp/src/teststatistics.cpp
Thanks in advance,
-M
Hello,
Try putting your declarations into a RItools.h file in inst/include/ or
src/ in your package, i.e. have this in RItools.h
typedef double (*testStat)(NumericVector, NumericVector);
and add:
PKG_CPPFLAGS += -I../inst/include/
to your Makevars and Makevars.win.
