R-beta: question on dyn.loaded code
...ies for R, is it possible to call C/Fortran
subroutines from other dynamically loaded code?
The following example crashes R:
********* fn1.c *****************
void twice(int *i)
{
*i = 2 * *i;
}
*********************************
********* fn2.c *****************
extern int twice(int *i);
void negtwice(int *i)
{
*i = -1 * twice(i);
}
*********************************
$ cc -fpic -c fn1.c
$ ld -shared fn1.o -o fn1.so
$ cc -fpic -c fn2.c
$ ld -shared fn2.o -o fn2.so
$ R
