The linking errors are related to RTTI (run time type information). This is because you built LLVM 3.4 CMake and the built `llvm-config` binary has a bug where it doesn't show the `-fno-rtti` flag. You have two options to fix this 1. Use the LLVM build that you produced using CMake but reconfigure KLEE by forcing the `-fno-rtti` flag. You will need to make a new build directory when you do this. Something like this ``` CFLAGS="-fno-rtti" CXXFLAGS="-fno-rtti" cmake -DENABLE_SOLVER_STP=ON -DENABLE_POSIX_RUNTIME=ON -DENABLE_KLEE_UCLIBC=ON -DKLEE_UCLIBC_PATH=../klee-uclibc -DENABLE_SYSTEM_TESTS=ON -DENABLE_UNIT_TESTS=OFF ../klee ``` 2. Rebuild LLVM using its autoconf/Makefile build system. This issue seem to keep appearing so we should improve our documentation to make it explicit that people should avoid building LLVM 3.4 using CMake.
