[Frama-c-discuss] Frama-c-discuss Digest, Vol 98, Issue 1

Hello Jens, 
Indeed it is the "ACSL by example", and the option "-wp-out" works perfectly! 
Moreover, I didn't have any strong reason to use the Sodium release. So I have upgraded my frama-c version to Magnesium, and all the goals are now proved (which was not the case with Sodium). 
Thank you very much for your help. 
Best regards, 
Paul Boniol

You could try the Frama-C option ‘-wp-out’, e.g., 

        "frama-c -wp -wp-out foo test.c test.h” 

Does this help?

By the way, is there a strong reason for you to use the Sodium release? 
I find the Aluminium better than Magnesium and similarly Magnesium better than Sodium.
