frama-c [kernel] user error: skipping file “selection.c” that has errors

Question

I am a new user of Frama-c. I just installed Neon-20140301 and why 2.34 on my Fedora 14 system with Ocaml compiler 4.01.0.

Under no-GUI mode, install was successful.

However, when I tried to run some examples from why2.34, I got several errors like the following: It seems that there is a compatibility problem.

[user  /data/Down/why-2.34/examples-c/sorting]$ frama-c -jessie selection.c
[kernel] preprocessing with "gcc -C -E -I.  -dD selection.c"

[kernel] user error: skipping file "selection.c" that has errors.

 /* Selection sort */

 //@ type intmset

  //@ logic intmset mset(int t[],int i,int j) reads t[..]

The question was asked in duplicate in the mailing list and answered by Claude Marché:

The examples in directory examples-c/ of why are old examples using Caduceus syntax, a kind of predecessor of Frama-C.

Up-to-date examples can be found in directory tests/c/ instead, and also in several other places, eg "ACSL by examples", etc.
