Summary0001437: Cannot use Frama_C_interval on Fluorine
DescriptionI tried following the instructions on the Fluorine manual to use Frama_C_interval():

frama -c -slevel 100 -val *.c `frama-c -print-share-path`/builtin.c >log 2 >&1

But the file "/usr/share/frama-c/builtin.c" cannot be found. I looked at the ZIP archive and could not find it on the /share folder, nor on any folder for that matter, the closest file is "libc/__fc_builtin.h". However, both builtin.c and builtin.h are present on the Oxygen ZIP archive, and I have successfully used Frama_C_interval with that version.

Has anything changed from Oxygen to Fluorine concerning this?

I tried just declaring the prototype and using it, but the value analysis does not output the expected result, for instance on this program:

int Frama_C_interval(int,int);
int main() {
  int i = Frama_C_interval(0, 20);
  return 0;

$ frama-c -val test.c

(... omitted ...)

Thanks for this report. We are already aware of this issue. A fix will be released quickly.

As a workaround, you can use the files builtin.[ch] from Oxygen.
