Project of using Clang+KLEE for C++ code test generator.

This is a repo of KLEE usage. Key results are provided in this issue (link).

Requirements:

• clang and clang++ version 13.0.1;

$ clang --version
Ubuntu clang version 13.0.1-2ubuntu2.2
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

• llvm version 13.0.1;

$ llvm-config --version
13.0.1

• z3 version 4.13.1;

$ z3 --version
Z3 version 4.13.1 - 64 bit

• built klee-uclibc library:

$ git clone https://github.com/klee/klee-uclibc.git ~/Downloads
$ cd ~/Downloads/klee-uclibc
$ ./configure --make-llvm-lib   
$ make -j2
$ cd -

• built libc++ library;
• google tests lib version 1.11.0.

Link to check info about KLEE installation: https://klee-se.org/build/build-llvm13/. Command with which I built KLEE:

mkdir -p Downloads/build
cd Downloads/build
cmake -DENABLE_POSIX_RUNTIME=ON -DENABLE_SOLVERS=Z3 -DKLEE_UCLIBC_PATH=/home/alex/Downloads/klee-uclibc -DENABLE_UNIT_TESTS=ON -DGTEST_SRC_DIR=/home/alex/Downloads/gtests/googletest-release-1.11.0/ -DENABLE_KLEE_LIBCXX=ON -DKLEE_LIBCXX_DIR=/home/alex/Downloads/libc++-install-130 -DKLEE_LIBCXX_INCLUDE_PATH=/home/alex/libc++-install-130/include/c++/v1/ /home/alex/Downloads/klee

As far as you see, I've installed it manually to /home/alex/Downloads/klee folder. That affects what is put into config.sh file.
