Unable to build flatc compiler flatbuffer v1.3.0 - cmake

Question

We are using flatbuffer v1.3.0 and seeing error building flatc compiler.
Same error for flatbuffer version v1.3.0 to v1.12.1
Build is successful for version 2.0.0
Should we use a particular version of make to build the flatc compiler? If so how to do it?
Steps
git clone https://github.com/google/flatbuffers/tree/v1.3.0
cd flatbuffers
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -Success
make --Error

Flatbuffer requires a specific version of clang to compile the 1.12.1.
Installing the required version.
sudo apt-get install clang-6.0 lld-6.0 clang-tidy-6.0
use update-alternatives to link the clang.
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-6.0 10
sudo update-alternatives --install /usr/bin/clang++ clang++
/usr/bin/clang++-6.0 10
