[klee-dev] libc function "open" is defined in POSIX runtime

[Cadar, Cristian]

Hi Gleb,

We applied various changes to uclibc to make it work with KLEE, so I 
think taking a look at those patches would help.  I don't recall the 
details, but based on a quick search, I think this patch might be 
relevant: 
https://github.com/klee/klee-uclibc/commit/7231f48dd8e2f9f15f721a77639d7eeea6efd38f

This PR from Martin might also be useful:
https://github.com/klee/klee/pull/483
Look in particular at linkWithMusllibc()

I would welcome changes to KLEE to make it easier to plug in other libc 
implementations.

Best,
Cristian
