# [Frama-c-discuss] [kernel] user error: skipping file "selection.c" that has errors.

Hi, everyone, 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. Is there any way to solve this? Thanks in advance! -------------------------------------------------------------------------------- [user /data/Down/why-2.34/examples-c/sorting]$ frama-c -jessie selection.c [kernel] preprocessing with "gcc -C -E -I. -dD selection.c" selection.c:4:[kernel] user error: unexpected token '' [kernel] user error: skipping file "selection.c" that has errors.
