bf-clang aborts with exit code 1

[AtanuBarai]

I am trying to use Byfl after installing from the source code (master branch). I am using GCC 8.3.0 and LLVM 8.0.1 on an Ubuntu 18.04 machine. But when I try to compile any program with bf-clang I get the following message.

atanu@labpc:~/Installers/Byfl/Byfl/tests$ bf-clang simple.c /usr/local/lib/libbyfl.so: undefined reference to `llvm::Value::getName() const' clang-8: error: linker command failed with exit code 1 (use -v to see invocation) bf-clang: Aborting

When I use bf-clang with verbose, I get the following output:

I haven't seen that exact error before. Two things to try that come to mind are

1. Generate a static Byfl run-time library instead of a shared library and use that instead (-DBUILD_SHARED_LIBS=OFF).
2. Link explicitly with the required LLVM libraries (-lLLVMCore, perhaps?).
