Cannot build binutils

[lmrs2]

Hi

I am trying out your fuzzer, thanks for making it open source! I'm running into troubles when compiling binutils. See steps below to reproduce:

wget https://ftp.gnu.org/gnu/binutils/binutils-2.27.tar.gz
tar xvzf binutils-2.27.tar.gz && cd binutils-2.27
mkdir build && cd build
CC=$ANGORA_DIR/bin/angora-clang CXX=$ANGORA_DIR/bin/angora-clang++ LD=$ANGORA_DIR/bin/angora-clang ../configure --disable-shared --disable-nls --disable-werror --disable-gdb --disable-libdecnumber --disable-readline --disable-sim
USE_TRACK=1 make

[...]

Note: Using USE_FAST=1 works. I've not had time to troubleshoot myself...

Thank you for your feedback. I am still debugging this issue. It seems I modify something wrong in my llvm pass or dfsan pass.

There are some other ways to bypass this issue.

• use gllvm & wllvm, I use this way to compile it now. see build angora by wllm
• or remove doc generation in binutils.

find . -name "Makefile*" -exec sed -i 's/SUBDIRS\s=\sdoc\spo/SUBDIRS =po/' {} + 

• or try to remove CXX=$ANGORA_DIR/bin/angora-clang++

I hope these can help you.

compiling with gllvm worked.
