Segfault on ".C" registration via R_CMethodDef according to 'Writing R Extensions'.
...encountered a serious problem regarding the registration of ".C" when following the documentation "Writing R Extensions"
that leads to a segmentation fault (tested on windows and mac os x).
The registration mechanism for ".C" routines via R_registerRoutines and
the R_CMethodDef structure has been enhanced recently with the
addition of two fields, one for type specification and the other for
the style (in, out, inout or irrelevant).
According to the manual 'Writing R Extensions' of version 2.14.1
an example is given that specifies to use the fourth field (type...

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 library(myincr),
the function doesn't seem to be...

Rinternals.h and undefined symbols
Hi,
I'm trying to register my native routines using R_registerRoutines
(...). I can compile the code, but the loader cannot resolve the symbol:
undefined symbol:
_Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6
_
$ nm bgx.Rcheck/bgx/libs/bgx.so | grep R_registerRoutines
U
_Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6
_
Why does it have this funny name? If I look at libR.so, I get an
ordinary symbol name:
$ nm ~/lib64/R/lib/li...

Embedding R and registering routines
Hello,
The use of .Call and the like all depend on loading shared libraries and
registering routines from it. Also, .Primitive and .Internal depend on
routines being registered in the R binary. And applications that embed R
can override routines declared in Rinterfac.h, but is there a way for an
application embedding R to register other routines defined in the
application without loading a
