[Rcpp-devel] rcpp compile problem

Hi

I am new to rcpp and am unable to compile code I know works. I must be
doing something stupid.

I am using Windows (10).

I have received the cpp source files for the BHPMF package. We want to
make the package work on the latest version of R.

I am currently using R 3.4.4 (the last version BHPMF works).

I have installed rcpp (install.packages("Rcpp")).

I have installed RTools.

The source files are in J:\TempWork\BHPMF_CRAN_Archive\src

I am using the RTools C++ compiler in

C:\Progs\Rtools\mingw_64\bin\c++.exe

When I try to compile, the compiler cannot find file R.h and ends with
error message:

J:\TempWork\BHPMF_CRAN_Archive\src>C:\Progs\Rtools\mingw_64\bin\c++.exe
HPMF_main.cpp

HPMF_main.cpp:11:35: fatal error: R.h: No such file or directory

#include <R.h>      // R functions

                                    ^

compilation terminated.

Can someone please tell me how I can tell the compiler to find R.h and
the other files from the rcpp package?

I  compile from the command prompt. Is this the right way or must I do
this in R?

Have I missed installing something? Have I installed staff in the wrong
order?

I see two options for compiling your packages.
1. You do

  R CMD build J:\TempWork\BHPMF_CRAN_Archive\

which should produce something like BHPMF_1.0.tar.gz (1.0 being an
example of package version). Then
  R CMD check J:\TempWork\BHPMF_1.0.tar.gz (put the true name of the
produced tarball here). After that you can see all used flags and
options in J:\TempWork\BHPMF.Rcheck\00install.out file.

2. In R session having J:\TempWork\BHPMF_CRAN_Archive\ as working dir you
do

  devtools::load_all()

The first option is better suited for final stages of your dev work
while the second one is more appropriate for your iterative dev cycles.

Best,
Serguei.

Thanks in advance.

Best wishes
