LLVM pass

I am getting the following error while implementing llvm function pass. Please help

…/…/…/bin/llvm-tblgen: error while loading shared libraries: libc++.so.1: cannot open shared object file: No such file or directory

I am not sure what you’ve done to end up with this issue, but until you get a proper response from someone, you can work around it by exporting LD_LIBRARY_PATH to where that library is on your system.
