Building

Setup

The build scripts put everything in $KLEE_ROOT for simplicity. You will need to install Z3 using the system package manager.

export KLEE_ROOT=path/to/some/root/dir

LLVM 9

Might work on newer versions of LLVM; unsure what upstream KLEE supports properly so sticking with 9 for now.

cd $KLEE_ROOT
git clone git@github.com:llvm/llvm-project.git
cd llvm-project/
git checkout llvmorg-9.0.1
mkdir build
cd build
cmake \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=$KLEE_ROOT/llvm-install \
  -DLLVM_TARGETS_TO_BUILD=X86 \
  -DLLVM_ENABLE_PROJECTS="clang;libcxx;libcxxabi" \
  ../llvm
make -j`nproc`
make install

KLEE-Float

cd $KLEE_ROOT
git clone git@github.com:mob-group/klee.git
cd klee
mkdir build
cd build
cmake \
  -DENABLE_SOLVER_Z3=On \
  -DENABLE_FLOATING_POINT=On \
  -DENABLE_FP_RUNTIME=On \
  -DLLVM_CONFIG_BINARY=$KLEE_ROOT/llvm-install/bin/llvm-config \
  -DCMAKE_INSTALL_PREFIX=$KLEE_ROOT/klee-install \
  -DENABLE_UNIT_TESTS=OFF \
  -DENABLE_SYSTEM_TESTS=Off \
  ../
make -j`nproc`
make install

Demo

cd $KLEE_ROOT
git clone git@github.com:mob-group/klee-demo.git
