I use Linker.linkPackages and Linker.getHValue to get symbol value, but looks Linker.getHValue can't get *update* value once current package has linked in memory.
So how to make Linker.getHValue can get *update* value and don't need install *new* package in Cabal/GHC database? How to *reload* module with current version package?
Cannot be done. Unfortunately, my library just miss this part. But i think reload same package must be can work, in principle.
I suggest using no packages if you want a module refreshed. This is means using GHC.setTargets and GHC.load (I personally use loadWithLogger for improved error handling). You can still use Linker.getHValue at the end. If not use package, we need handle depend problem self. Example, same module name exist in two different depend package, we need pass -package information myself, and no those problems if use cabal package.

Do you have any improve code than above? :) Thanks for help! -- Andy
