How to fix missing libLLVM-13.so libraries

I am using Arch Linux and I installed llvm using sudo pacman -S llvm. I installed some programs like ccls, clangd, cppcheck etc. and none of them are working: ccls: error while loading shared libraries: libLLVM-13.so: cannot open shared object file: No such file or directory clangd: error while loading shared libraries: libLLVM-13.so: cannot open shared object file: No such file or directory cppcheck: error while loading shared libraries: libtinyxml2.so.9: cannot open shared object file: No such file or directory How to fix these?
