Hi, folks, I just want to throw in another vote for Rcpp. I recently rewrote some old code that used the legacy interface to use Rcpp, and life with Rcpp is *much* better. The code is clean and easy to read (and write), and memory protection is taken care of. I don't know if it will fix Pierre's specific problem, but if you try it, I suspect you'll like it.
Many thanks to Dirk, Romain, and all.

Have you looked at RCpp package? ________________________________________ From: R-package-devel [r-package-devel-boun...@r-project.org<mailto:r-package-devel-boun...@r-project.org>] on behalf of Pierre Lafaye de Micheaux [laf...@dms.umontreal.ca<mailto:laf...@dms.umontreal.ca>] Sent: Friday, November 13, 2015 10:24 AM To: r-package-devel@r-project.org<mailto:r-package-devel@r-project.org> Subject: [R-pkg-devel] Problem (with complex.h?) under Microsoft Windows I created a new version of the package IndependenceTests where I call some C and Fortran functions (using the .C() or .Fortran() interface). It works perfectly under Linux, with gcc. No problem with R CMD check. I would like to upload this package on the CRAN. But when I first tried to use winbuilder, I got an error with the following message: * installing *source* package 'IndependenceTests' ... ** libs *** arch - i386 g++ -I"D:/RCompile/recent/R/include" -DNDEBUG -I"d:/RCompile/r-compiling/local/local320/include" -O2 -Wall -mtune=core2 -c Cnhat.cpp -o Cnhat.o Cnhat.cpp:9:89: error: 'complex' has not been declared Cnhat.cpp:9:105: error: two or more data types in declaration of 'res' .... ..... etc. I think I understand that there is a problem (only under Windows though) with the complex type. The beginning of my file Cnhat.cpp is as follows: 1. #include <R.h> 2. #include "Rmath.h" 3. #include <complex.h> 4. #include <iostream> 5. using namespace std; 6. 7. extern"C" { 8. 9. void CnhatC(double *vecs, double *vect, double *X, int *n, int *q, int *p, int *vecd, complex double *res) { 10. 11. void phinhatReturn(double *vect1, double *vect2, double *vect3, double *X, int *q, int *n, double _Complex *res1, double _Complex *res2, double _Complex *res3); 12. double _Complex tmp2, prod1 = 1.0 + 0.0*_Complex_I, prod2 = 1.0 + 0.0*_Complex_I, somme = 0.0 + 0.0*_Complex_I; 13. int indbeginblocl, l, i, *vecdl, k, j; 14. double *vecsl, *mvectl, *diffvecsvectl, *Xl; 15. double _Complex *res1, *res2, *res3; 16. vecdl = new int[1]; 17. res1 = new _Complex double[1]; .... ..... etc. As you can see, there seem to be some problem (on line 9.) with: complex double *res Could you please point me to something (e.g., another package) that might help me solve the problem? If possible, I would like to avoid invest too much time using the new .Call() interface because I am quite familiar with the old .C(). And also I am not even sure if it would help solving the problem.
