Segfault on ".C" registration via R_CMethodDef according to 'Writing R Extensions'.
...}', I get the following error:
*** arch - i386
g++ -arch i386 -I/Library/Frameworks/R.framework/Resources/include -I/Library/Frameworks/R.framework/Resources/include/i386 -I/usr/local/include -fPIC -g -O2 -c reg.cpp -o reg.o
reg.cpp:30: error: braces around scalar initializer for type ???R_NativePrimitiveArgType*???
(line 24 is the point on the entry, while line 30 is the end of the overall array initialization list in C++).
If I put the type and style (unsigned int and enum) arrays separately,
the build process works just fine. E.g.
R_NativePrimitiveArgType types[] = {REALSXP, INTSXP, STRSXP, LGLSXP};...

passed 4 arguments, but takes just 1
/usr/include/c++/4.0.0/bits/codecvt.h:216: error: expected ';' before 'const'

Line 51 refers to the standard part to register the function in R:
R_CMethodDef cMethods[] = {
{"runSimulation", (void* (*) ()) &runSimulation, 27, {INTSXP,
INTSXP, INTSXP, REALSXP, REALSXP, REALSXP, INTSXP, INTSXP, INTSXP,

R Interface handholding
...;
PROTECT(returner = NEW_INTEGER(input));
Rprintf("Hey there\n");
return returner;
}
I've made this into a package, by dropping it into a stub directory
along with something called init.c:
#include "areone.h"
#include <R_ext/Rdynload.h>
#include <Rinternals.h>
R_NativePrimitiveArgType myincr_t[1] = {INTSXP};
static const R_CMethodDef cMethods[] =
{
{"myincr", (DL_FUNC) &myincr, 1, myincr_t}
};
void R_init_myincr(DllInfo* dll)
{
R_registerRoutines(dll, cMethods, NULL, NULL, NULL);
}
R is happy to install this for me, but after doing a lib...

R_CMethodDef incompatibility (affects R_registerRoutines)
I recently noticed a change between R-3.3.3 and R-3.4.0 in the definition
of the R_CMethodDef struct.
typedef struct {
const char *name;
DL_FUNC fun;
int numArgs;
-
R_NativePrimitiveArgType *types;
- R_NativeArgStyle *styles;
-
} R_CMethodDef;
I suspect this is the reason that packages installed by R-3.4.0 and loaded
into R-3.3.3 will crash the latter if the package registers routines to be
called from .C or .Fortran:
% R-3.3.3 --quiet
