Hi, it seems as I thought, 'clamav 12.0.1' won't build with 'llvm 12.0.1'. During building with "-D BYTECODE_RUNTIME="llvm" \", I get: ... CMake Error at cmake/FindLLVM.cmake:186 (if): if given arguments: "12.0.1" "VERSION_LESS" Unknown arguments specified Call Stack (most recent call first): CMakeLists.txt:466 (find_package) -- Configuring incomplete, errors occurred! See also "/usr/src/clamav-0.104.0/build/CMakeFiles/CMakeOutput.log". See also "/usr/src/clamav-0.104.0/build/CMakeFiles/CMakeError.log". make: *** [clamav:89: /usr/src/log/clamav-0.104.0] Error 1 ... With option "-D BYTECODE_RUNTIME="none" \" its building again. Opinions? Best, Matthias
