(may take several hours to complete - 5-6 h in my case; setting the build type to Release should speed up the process a bit, though) #Build FuzzGen (Taken from the Readme and modified) (1. FuzzGen has already been cloned beforehand) 2. sudo apt-get install libboost-all-dev 3. export LLVM_DIR=/llvm-project/build (not really optional, right?; targeting other versions will fail later on; is it necessary to specify the exact build directory, that had been created while building LLVM-6.0.0?) 4. cd FuzzGen 5. mkdir build 6. cd build 7. cmake .. 8. make -j$(nproc)
