Compilation error

[kimiwanano]

Hi. I'm trying to test the Fuzzer Test Suite with AFL, and here are the changes I made to the two script files. After making the changes, I tried compiling each file with build.sh. However, the compilation error is shown in bold at the end. How can I fix it?

#FUZZING_ENGINE=${FUZZING_ENGINE:-"fsanitize_fuzzer"}
FUZZING_ENGINE=${FUZZING_ENGINE:-"afl"}

#AFL_SRC=${AFL_SRC:-$(dirname $(dirname $SCRIPT_DIR))/AFL}
AFL_SRC=${AFL_SRC:-/AFL-master}

#export CC=${CC:-"clang"}
#export CXX=${CXX:-"clang++"}
export CC=${CC:-"afl-clang-fast"}
export CXX=${CXX:-"afl-clang-fast++"}
