hello, I'm having trouble installing rocm on my computer my system is ubuntu20.04, I try to install rocm-v4.3 following this guidance but things go not well when I finished, it seems like something is missing here are some check command outputs:

:~$ hipcc --version
sh: /opt/rocm/llvm/bin/clang: No such file or directory

by the way, I notice a lot of things are missing in the /opt/rocm folder, like hsa please help me.

I notice some important library is missing, like libamdhip64.so, libhsa_runtime.so, etc.

1. the reason for the underneath error is because I haven't installed HIP-clang and ROCm Device-Libs, which must be built manually. guidance can be found here, by the way, this guide seems not working well, there are some changes that need to be done.

   sh: /opt/rocm/llvm/bin/clang: No such file or directory

2. the reason for the other error is because rocminfo is not installed correctly, I tried build it manually, and solved this warning.

   Can't exec "/opt/rocm/bin/rocm_agent_enumerator": No such file or directory at /usr/bin/hipcc line 592.

   I found a very helpful instruction of installing rocm on ubuntu system, here by the way, the installation guide in the rocm doc is not friendly (T _ T).
