Steps to Reproduce the Problem

  1. Download spec file https://github.com/OpenMandrivaAssociation/cryfs
  2. Use LLVM/Clang 8.0x and LTO
  3. run rpmbuild

Looks like linking is missing boost libraries. This time i've ran build without LTO. https://abf.openmandriva.org/build_lists/27483

LTO works for me, but I am using gcc (9.1) and have not tested LTO with clang.

This looks weird because it tries to build a dynamic library libcryfs-cli.so. CryFS should build everything statically by default.

CryFS in the develop branch now uses Conan for getting the boost dependency. Can you retry? I think with Conan, it should work now.
