klee linker problem

Hello everyone,

I am a novice with KLEE under LLVM. I am trying to build a KLEE project (on a new LLVM environment) and I have the following problem:

echo Testing…
Testing…
echo There should be no assertion fails!
There should be no assertion fails!
klee -taint=direct taint_direct.o
KLEE: output directory = “klee-out-8”
klee: error: Cannot find linker input ‘/tmp/taint/klee/Release+Asserts/lib/libkleeRuntimeIntrinsic.bca’
klee: ModuleUtil.cpp:51: llvm::Module* klee::linkWithLibrary(llvm::Module*, const string&): Assertion `0 && “linking in library failed!”’ failed.

12 klee 0x00002ac2cc72da6d
make: *** [direct] Aborted (core dumped)

The problem is that KLEE is trying to look into /tmp/taint/…libkleeRuntimeIntrinsic.bca and not into /home/myfolder/taint/…where libkleeRuntimeIntrinsic.bca does exist. I think I set correctly all the paths when I installed KLEE (and not from the /tmp/ folder).

Do you know how I can solve this problem, what command lines to make KLEE not to point to the /tmp/ folder ?

Thank you in advance !

Hi,

The klee library directory is determined at compile time and cannot be changed afterwards. Have a look at tools/klee/main.cpp to see how it is computed.

I usually use Klee without any install step, right from the build directory. This has never given me the error you see.

Hope this helps,
Jonas

Thanks you for your answer !
