[vladimirtelepov]

OS: Ubuntu20.04 CC=Clang-12 CXX=Clang++-12

this commands works fine:

git clone --depth 1 --single-branch --branch master https://github.com/lifting-bits/remill.git
git clone --depth 1 --single-branch --branch master https://github.com/lifting-bits/mcsema.git
git clone --branch master https://github.com/lifting-bits/anvill.git
( cd anvill && git checkout -b release_bc3183b bc3183b )
export CC="$(which clang)"
export CXX="$(which clang++)"
./remill/scripts/build.sh --llvm-version 12 --download-dir ./
pushd remill-build
sudo cmake --build . --target install
popd
mkdir anvill-build
pushd anvill-build
cmake -DVCPKG_ROOT=$(pwd)/../vcpkg_ubuntu-20.04_llvm-12_amd64 ../anvill

but

sudo cmake --build . --target install

fails with error message

You can patch the source by replacing createConstantPropagationPass with createInstSimplifyPass

This is an LLVM API change, I thought it was in 13, not 12 though.

@michaelbrownuc any updates on issue? I tried build latest version(82c310697f1019bafee72265c490ac4aa959e2aa) but error still occur. File compiles after removing optimization. But other error occurs. After removing quotes and next try other error occur.

[michaelbrownuc]

IIRC there are a few API changes to make, including the one in the second screenshot. In that case removing the -1 parameter should solve that compiler error.

[vladimirtelepov]

@michaelbrownuc now have this error

[vladimirtelepov]

@invlpg seg_type is used and returned later in function GetSegmentType so just removing code doesnt work.

[xathrya]

simply removed that optimization and it compiles.

// fpm.add(llvm::createInstSimplifyPass());

Also "getTypeByName" is not in "llvm::Module" it seems? https://reviews.llvm.org/D78793

had to remove this code to get it compiling on llvm 12.

https://github.com/lifting-bits/mcsema/blob/87239ee2879b7ce7f8274a8b868d09bf0867acd3/mcsema/BC/Segment.cpp#L106

  auto seg_type = gModule->getTypeByName(type_name);
  if (seg_type) {
    return seg_type;
  }

getTypeByName is moved to other place. Try this, it work for me

auto seg_type = llvm::StructType::getTypeByName(gModule->getContext(), type_name);

[vladimirtelepov]

Thanks, it works.
