[klee-dev] Arch linux: Cannot build Klee , stuck with "Unable to link with libstp"

[Daniel Liew]

The new issue you are seeing now has nothing to do with STP. It is to
do with your LLVM bitcode compiler. LLVM Bitcode is not stable between
releases of LLVM (i.e. you cannot mix LLVM bitcode generated by
LLVM2.9 and LLVM3.3)

If see the configure output...

Using C llvm compiler : /usr/bin/clang
Using C++ llvm compiler : /usr/bin/clang++
checking C LLVM Bitcode compiler works...
/nfs/adaptive/tnguyen/Src/Devel/KLEE/llvm-2.9/Release+Asserts/bin/llvm-dis:
Unknown bitstream version!
configure: error: Failed converting LLVM Bitcode to LLVM assembly.
Maybe your LLVM versions do not match?

Configure is trying to use your system's clang as the LLVM bitcode
compiler (which is probably Clang 3.3 or 3.4, depending on when you
last ran ``pacman -Syuu``). This won't work (if you use LLVM2.9) and
configure rightly stops you from going any further. If you intend to
use LLVM2.9 with KLEE then you need to put the llvm-gcc [1] compiler
in your PATH before running KLEE's configure script.

[1] http://llvm.org/releases/2.9/llvm-gcc4.2-2.9-x86_64-linux.tar.bz2
or http://llvm.org/releases/2.9/llvm-gcc-4.2-2.9-i686-linux.tgz


Hope that helps.
Dan.
