Compiling latest git

[Quentin Stievenart]

Hi all,

I am trying to setup the git version of klee on my machine (running a Linux
3.14.19, x86_64, GCC 4.9.1). I had some troubles running an older klee on the
coreutils binaries. I followed the tutorial at
http://klee.github.io/klee/GetStarted.html to install it. To minor changes were
needed:
1. Compiling LLVM 2.9 failed as an include of unistd.h was missing in one
file, due to changes in GCC
2. I used the git version of STP, as the version linked in the tutorial didn't
compile at all

Following the tutorial at http://klee.github.io/klee/TestingCoreutils.html, I
can get Steps 1 and 2 working, but on Step 3 I get the following error:

$ klee --libc=uclibc --posix-runtime ./cat.bc --version
klee: main.cpp:1104: llvm::Module* linkWithUclibc(llvm::Module*,
llvm::StringRef): Assertion `ft->getNumParams() == 7' failed.
0 klee 0x0000000000d0d0ef
1 klee 0x0000000000d0d664
2 libpthread.so.0 0x00007ffff7bcf200
3 libc.so.6 0x00007ffff689f967 gsignal + 55
4 libc.so.6 0x00007ffff68a0d3a abort + 362
5 libc.so.6 0x00007ffff68988ad
6 libc.so.6 0x00007ffff6898962
7 klee 0x000000000053c0bf main + 11695
8 libc.so.6 0x00007ffff688c040 __libc_start_main + 240
9 klee 0x0000000000548a42

I therefore tried to build latest git version of klee, with latest klee-uclib
and current LLVM (3.5), but I can't get klee to compile:

ModuleUtil.cpp:217:54: error: no member named 'begin_children' in
'llvm::object::Archive'
for (object::Archive::child_iterator AI = archive->begin_children(),
~~~~~~~ ^
ModuleUtil.cpp:218:22: error: no member named 'end_children' in

~~~~~~~ ^

^
[...]

However, I see that travis-ci reports that klee successfully builds. Any idea
why it fails here? Is there any up to date page summarizing with which version
of which software (llvm/gcc/stp/klee-uclibc) is klee working?

Thanks in advance,
Quentin

Hi Quentin,

For LLVM 2.9 to compile, you need to make a small change:
https://www.mail-archive.com/klee-dev-AQ/***@public.gmane.org/msg01302.html
Also for STP r940 (if you don't want to use the upstream STP version):
https://github.com/stp/stp/commit/ece1a55fb367bd905078baca38476e35b4df06c3

Currently, LLVM 2.9 is supported and 3.4 has only experimental support.
So if you want to try a newer LLVM version, try 3.4 instead of 3.5.
There is a (bit hidden) guide about setting up KLEE with it:
http://klee.github.io/klee/Experimental.html

For me on 64-bit Ubuntu 14.04 (3.13.0) with GCC 4.8 all versions
mentioned in the setup tutorials worked. I used both upstream STP and
r940, and LLVM 2.9 and 3.4. I've just tried setting up everything with
GCC 4.9.1 and there were no problems, either.

Best regards,
Emil
