I'm trying to upgrade agda, getting a memory error. Any ways to fix this?
I tried cabal install --ghc-options="+RTS -M600M" --force-reinstalls agda but per a similair question, but this just gave a heap error.
wmacmil@w:~$ cabal install --force-reinstalls agda

This may be due to an out-of-memory condition.
Ah, GHC's memory hunger is insaturable...
What I usually do for bigger installs is, hardly limit GHC's -M (or perhaps to 80% of the total memory), but ensure that it actually has all of this available per-process, by limiting compilation to a single process.
cabal install --ghc-options="+RTS -M7G" -j1 --force-reinstalls agda
Obviously, this makes it all really slow, but at least it'll generally succeed.
