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.
