I am new to Frama-C framework and I am trying to do some contract testing with C programs. I intend to use E-ACSL plugin for this, and I tried a test program to see how it works, but I get some compilation errors. Here is my code:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int x = 0;
/*@ assert x == 1;*/
/*@ assert x == 0;*/
return 0;
}
Then, here is the Frama-C annotated code:
/* Generated by Frama-C */
#include "stdio.h"
#include "stdlib.h"
struct __e_acsl_mpz_struct {
int _mp_alloc ;
int _mp_size ;
unsigned long *_mp_d ;
};
typedef struct __e_acsl_mpz_struct __e_acsl_mpz_struct;
typedef __e_acsl_mpz_struct ( __attribute__((__FC_BUILTIN__)) __e_acsl_mpz_t)[1];
/*@ ghost extern int __e_acsl_init; */
/*@ ghost extern int __e_acsl_internal_heap; */
extern size_t __e_acsl_heap_allocation_size;
/*@
predicate diffSize{L1, L2}(ℤ i) =
\at(__e_acsl_heap_allocation_size,L1) -
\at(__e_acsl_heap_allocation_size,L2) ≡ i;
*/
int main(void)
{
int __retres;
int x = 0;
/*@ assert x ≡ 1; */ ;
/*@ assert x ≡ 0; */ ;
__retres = 0;
return __retres;
}
Finally, I try to compile it with gcc and the flags the manual indicates (page 13) but I get the following errors (and warnings):
$ gcc monitored_second.c -o monitored_second -leacsl -leacsl-gmp -leacsl -jemalloc -lpthread -lm
monitored_second.c:10:1: warning: ‘__FC_BUILTIN__’ attribute directive ignored [-Wattributes]
typedef __e_acsl_mpz_struct ( __attribute__((__FC_BUILTIN__)) __e_acsl_mpz_t)[1];

int line);
^
monitored_second.c:25:60: warning: ‘__FC_BUILTIN__’ attribute directive ignored [-Wattributes]
size_t ptr_size);
^
/usr/bin/ld: cannot find -leacsl
/usr/bin/ld: cannot find -leacsl-jemalloc
collect2: error: ld returned 1 exit status
I've also removed the "-rtl-bittree" label because it returns another error.
Frama-C version is the latest: Sulfur-20171101 Got any idea of what is happening?
Thanks!
