Kouhei Sutou commented on ARROW-9533:
-------------------------------------
We removed LLVM (and Gandiva) by ARROW-5082 because it increases .whl size.
And we removed LLVM from our .whl build images by ARROW-9094.
We added support for LLVM 10 by ARROW-9004 but it's not used because we don't
use LLVM now.

Could you show the URL of the manylinux1 docs?
I think that custom .whl isn't a good approach for you. It'll be difficult to
maintain. Could you show assumed user environment of your custom .whl?
BTW, {{LLVM=8 docker-compose ....}} is recommended than {{docker-compose build
--build-arg llvm=8 ...}}.

> Attempting to set LLVM_DIR using export LLVM_DIR does not work. Also, setting

> a file called FindLLVM.cmake which does not exist and there is only
