All,
I've been working with the dataspace calls with the L4Env running x86
Fiasco. I am trying to create a dataspace from a L4Linux user process,
but I am having trouble getting the program to compile. Is my Makefile
correct for what I am trying to do? Is there any reason I shouldn't be
able to link to l4dm_mem_open from a L4Linux user process? Below is my
source, Makefile, and compiler error message. Help much appreciated!
---------- SOURCE ----------
#include <l4/dm_mem/dm_mem.h>
#include <l4/l4rm/l4rm.h>
#include <l4/sys/types.h>
#include <l4/dm_generic/types.h>
int main(int argc, char**argv){
l4dm_dataspace_t ds;
void *addr;
l4dm_mem_open(L4DM_DEFAULT_DSM,8192,0,0,"L4RM example",&ds);
printf("hi\n");
return 0;
}
---------- MAKEFILE ----------

L4DIR ?= $(PKGDIR)/../..
