Summary0001695: Impossible to compile the eacsl produced source
DescriptionThis code is generated. It is compilable.

However when instrumented on a part of the code, gcc is not anymore able to compile it:
/tmp/cc3Hv08h.o: In function `__e_acsl_memory_init':
test4.c:(.text+0x43c): undefined reference to `__fc_stdout'
/tmp/cc3Hv08h.o: In function `main':
test4.c:(.text+0x52b): undefined reference to `__fc_stdout'
collect2: error: ld returned 1 exit status

Same behavior when applied on all the code.
Steps To ReproduceRun the run.me script.

Your example is not standalone:

Generating non instrumented binary
In file included from cpt.c:3:0:
cpt.h:9:46: fatal error: /usr/local/include/lustrec/arrow.h: No such file or directory
compilation terminated.
cpt_cpt.c:3:52: fatal error: /usr/local/include/lustrec/io_frontend.h: No such file or directory
compilation terminated.

Could you provide the missing files?

Here is a small reproducible example:
=====
#include <stdio.h>

int main(void) {
  int x = 2;
  printf("x = %d\n", x);
  return 0;
}
=====

The issue comes from using some functions of stdio.h and the way they are defined in the Frama-C libc library..

The hack "grep -v _fc_stdout" works pretty well. The code is compiled and behave as expected.
