[libcxx-dev] Problem installing libcxx and libcxxabi using Bootstrapping on Amazon Linux 2

[Hasan Marzooq via libcxx-dev]

Perfect! plv8 is installed now. Thanks again for your help! A big relief -:)

Previously, if you notice, I've installed "opt" via yum. This was because I
didn't find opt in the command line even after having below cmake
configuration.

cmake -G Ninja -S llvm -B build -DLLVM_ENABLE_PROJECTS="clang;llvm"
-DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind"
-DLLVM_PARALLEL_LINK_JOBS=1 -DCMAKE_BUILD_TYPE=Release

My assumption was that having llvm in -DLLVM_ENABLE_PROJECTS will build
"opt" as well.

-----
# pwd
/root/llvm-project/build/tools/opt
# cmake -P cmake_install.cmake
-- Install configuration: "Release"
CMake Error at cmake_install.cmake:46 (file):
  file INSTALL cannot find "/root/llvm-project/build/bin/opt": No such file
  or directory.
-----

Didn't had opt under "/usr/local/lib" either.

I want to use the above cmake approach for building and installing "opt"
instead of installing via yum.


Thanks!
