Various errors when using vanilla Angora to build a target

[RoelVdP]

cd ~
git clone https://github.com/AngoraFuzzer/Angora.git Angora-llvm4
cd Angora-llvm4
mkdir llvm4
PREFIX=${PWD}/llvm4 ./build/llvm.sh .
${PWD}/llvm4/clang+llvm/bin/clang --version  # 4.0.0
${PWD}/llvm4/clang+llvm/bin/llvm-config --version  # 4.0.0
export PATH=${PWD}/llvm4/clang+llvm/bin:$PATH
export LD_LIBRARY_PATH=${PWD}/llvm4/clang+llvm/lib:$LD_LIBRARY_PATH
./build/build.sh

Then follow steps on https://github.com/AngoraFuzzer/Angora/blob/master/docs/example.md i.e.

cd ~
mkdir angora-test && cd angora-test
wget https://github.com/file/file/archive/FILE5_32.tar.gz
tar -xvzf FILE5_32.tar.gz
cp -r file-FILE5_32 track
cd track
autoreconf -i
CC=~/Angora-llvm4/bin/angora-clang ./configure --prefix=`pwd`/install --disable-shared

The following is using llvm4 compiled using the instructions from the README and Angora build from the main Angora trunk;

Sorry for my late reply. I tried your commands, and can not reproduce this issue. Please try

cargo clean
cd llvm_mode && make clean

then recompile Angora.

Or tried the docker version we provide.
