If you examine the log it's clear that the problem is theirs, and nothing to do with this package or its dependencies. It's a shame this is so prominently displayed and impossible to remedy, it makes unbroken packages seem broken to visitors, and it exerts negative pressure on the use of cpphs and other build-tools./ extra-source-files: README , changelog.txt , hackage-tags.txt , HTML/*.html , HTML/*.css , deepseq-bounded-seqaid-leaky.html , deepseq-bounded-seqaid-leaky.css , rough-fs-twiddling-guide.txt , leaky-full.hs , leaky-full-incl-types.hs -- , Types_no_SOP.hs -- , Types_explicit_SOP.hs , seqaid.config -- oops... , seqaid.config_no_SOP , seqaid.config_explicit_SOP , seqaid.config-full , seqaid.config-full-incl-types --- , seqaid.config-full-no2ndmod , leaky-min-cppd.hs , leaky-min-cppd-working.hs , leaky-min.hs , Types_min.hs , seqaid.config-min -- , LICENSE -- , leaky.cabal -- , Setup.hs --- , cabal.config -- XXX Would be nice if could avoid the TH when FORCING_STRATEGY < 4. Flag HELLO_HACKAGE_VISITOR Description: [Note to those reading on Hackage:] Please ignore these flags, which would be better presented in a collapsed state. The flags are mostly for development purposes. Default: False Manual: True Flag TURN_ON_SEQAID_PLUGIN Description: Only when True, provide the options to enable the seqaid preprocessor and GHC plugin. Default: True --Default: False Manual: True Flag OMNITYPIC Description: Blanket seqaid harness at subexpressions of all possible types. Shouldn't need a Cabal flag for this, but it's the same problem of casing over integer values for a macro (in a .cabal file). So this need not be orthogonal to FORCING_STRATEGY, but this way it is ... which is okay, actually. (Can then test interactions with other FS=0..6.) --Default: True Default: False Manual: True Flag TEST_SEQAIDPP Description: Finally crumbed and availed myself of -F -pgmF, although only for things which are /fairly/ safe via regex (injecting imports, top-level splices, "deriving instance" statements, LANGUAGE pragmas, etc.). (Later: You can't really do without this anymore, although with FORCING_STRATEGY=4 it is possible.) Default: True --Default: False Manual: True Flag STATS Description: Dump periodic stats lines, for FORCING_STRATEGY that need it. Default: True --Default: False Manual: True Flag USING_SANDBOX Description: I use them, but it's not default because it makes for much longer initial build, as all the dependencies (except base libs) need first to be installed into the sandbox. --Default: True Default: False Manual: True Flag USE_SECOND_MODULE Description: Temporary for testing... (Later: Sadly this is not so temporary. There is some kind of interference between SOP.TH and Seqaid.TH splices which is still unresolved. So, types needing NFDataP (etc.) instances will need to live in a module which is /not/ being harnessed.) Default: True --Default: False Manual: True Flag PROFILE Description: Enable profiling --Default: True Default: False Manual: True Flag USE_GROWING_LIST Description: The problem with using a growing list is, it itself is a leak (as it were), so it's hard to see you've plugged anything. However, the slowdown of "force" relative to "forcep" will be noticed! Alternative to GROWING is FIXED (is at length 10000 at the moment). Fixed list is infinite if INFINITE set below. (INFINITE has no effect when GROWING set.) Default: True --Default: False Manual: True Flag USE_GROWING_LIST_REDUCTION Description: XXX For some reason, memory is being retained when REDUCTION is enabled. (Later: Is this still the case? I see it's been set to True throughout development...). Default: True --Default: False Manual: True Flag USE_INFINITE_LIST Description: To show DeepSeq.force (FORCING_STRATEGY=1) at its worst. --Default: True Default: False Manual: True Flag USE_STRICT_BLOB Description: Put some weighty strict subtrees in the test data structure, so can showcase forcep's specificity relative to forcen. Default: True --Default: False Manual: True -- Flag FORCING_STRATEGY -- Description: -- --Default: 6 -- Default: (6::Int) ------- -- Sadly, not. -- See bottom of this file for the meanings of the values. -- This does indeed work for me (it is auto-toggled when cpphs is unavailable). -- Default to False, since it seems more likely there's a native cpp, than -- that a cpphs installation works smoothly. Flag USE_CPPHS Description: Non-manual flag to allow the build system to try cpphs first, and if that fails, then to try system-wide cpp (typically GNU). I've actually toggled the default, so the build system will try for a system-wide cpp first, and failing that, will try to use cpphs, installing it if necessary. I prefer cpp. I am not getting my most invaluable -Wundef option with cpphs using -optP-Wundef -optP--cpp in my ghc-options. Does cpphs implement it? Not sure... Default: False --Default: True Manual: False Flag COWBOY Description: Non-manual flag to try to respond to rogue build failure reports but misconfigured auto-build systems.
