Unable to build simple C++ app using clang++ on ubuntu

Question

I am unable to build a simple hello world application using clang-6.0 on bionic beaver, the build command fails with below error.

 clang++-6.0 -std=c++17 -stdlib=libc++ hello.cc -o hello 
/usr/bin/ld: cannot find -lc++abi
clang: error: linker command failed with exit code 1 (use -v to see invocation)

what is this c++abi library and where can i find it ?? Please advise.

Are you using linux machine ? then use packages.ubuntu.com/trusty/libdevel/libc++abi-dev link to download lib. — SYAM KRISHNA MG

sudo apt-get install libc++abi-dev command will fix the problem.

If you are using a non-default version of Clang, you will have to install a more specific version, e.g. libc++abi-12-dev.

Thanks @Ravikumar-Tulugu and @Martin-Valgur. In my case (Fedora) I installed the equivalent that is in package lbcxxabi.
