Additional context
Add any other context about the problem here.
Bcc-static default USES ENABLE_LLVM_SHARED=OFF, which causes Polycubed to compile LLVM_liBS in the BCC into the executable at compile time.But Polycubed dynamically links clang, which links to LLVM's dynamic libraries, causing the problem.I recommend that add the option ENABLE_LLVM_SHARED to src/CMakelists.txt
@sebymiano Did you experienced anything about this? @l30006821 Would it possible to propose a patch? Thanks!
@frisso Honestly, I have never had this kind of problem, but I haven't tested the latest versions of Polycube. I don't know if there have been some changes recently in Polycube/BCC that could cause this problem.
