While there's no binary distribution for FreeBSD at haskell.org, as of June 30 there's a FreeBSD ghc-8.4.3 port. https://svnweb.freebsd.org/ports/head/lang/ghc/Makefile?view=log FWIW, while building it I saw a compiler warning: libraries/Cabal/Cabal/Distribution/Simple/Program/Builtin.hs:62:1: warning: [-Wunused-imports] The import of ‘System.FilePath’ is redundant except perhaps to import instances from ‘System.FilePath’ To import instances alone, use: import System.FilePath() | 62 | import System.FilePath (takeDirectory) | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ one thing that puzzles me is that on MacOS/X and Linux running Haskell code has a fixed virtual size of 1TB, while on FreeBSD the "vsz" reported by "ps", "top", ... is rought what you'd expect given the actual memory usage of the program plus overhead from generational GC. I am curious as to why the process memory model is platform-dependent in this manner. It seems as though on many platforms the RTS gives the process a large virtul address space, and then allocates memory by fauliting-in previously unused pages, whereas on FreeBSD brk(2) (via sbrk() or malloc(), ...) is used to extend the process virtual size on demand. -- Viktor.
