Hello,

Please also try setting

export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu

Best Regards,

Dear all,

I got the same error in this thread http://keeda.stanford.edu/pipermail/klee-dev/2012-September/000925.html, and I follow the solution that Dan Liew suggested but it still gave me the same error.

For more specific, firstly I located the librt.a
locate librt.a
/home/turtle/klee-uclibc/lib/librt.a
/usr/lib/x86_64-linux-gnu/librt.a

So I add the latter address to path:

export LLVM_LIB_SEARCH=/usr/lib/x86_64-linux-gnu

After running make, I still got the error

Does anyone know what caused this error?
