[Frama-c-discuss] Frama-C compilation: questions on APRON, test error and missing plugin?

We would be happy to have them in order to be able to provide them to
others, or even to fix what is fixable.

We will.

Note that at this time APRON is used only by the Jessie plug-in
for trying to find invariants automatically on functions that make
use of common C string manipulation idioms.

Another polyhedra library, NewPolka, is always compiled in APRON,
so don't worry about it.

They are experimental and therefore not distributed at this point.
We will try to make this clearer in the output of configure.

The difference that you see is caused by the name of a temporary
file which changes from execution to execution. The real problem is
that this name shows in the log because Frama-C fails to
run on this particular example. A file, minix3_include/string.h, seems
to be missing. This may be an omission on our part. Again, do not
worry about it, it does not imply that Frama-C is incorrect or
mis-installed on your computer.

I have heard that sources for Simplify were still floating around,
again please follow the links from the Why webpage and see if
what you find is acceptable to you (shortcut: you'll probably end up at
at some point).
Although Zenon is not listed on the Why webpage, I think that there
is a good chance that it is supported:
