Hi, Building GHC HEAD (git HEAD SHA1 = 88f476b98709731d997ab57612cce4753cb65a0a) this morning, I've encountered 2 build failures that seem to be a result of some recent changes in the past day or two. If I build a clean repository with `make -j13` on my 12 core machine, I get: ------------------------------------------------------------------------------ compiler/hsSyn/Convert.lhs:178:30: `td_fvs' is not a (visible) field of constructor `TyData' compiler/hsSyn/Convert.lhs:190:31: `td_fvs' is not a (visible) field of constructor `TyData' make[1]: *** [compiler/stage2/build/Convert.o] Error 1 make[1]: *** Waiting for unfinished jobs.... --------------------------------------------------------------------------- However, reinvoking `make` with no parallelism and attempting to continue the build (there's no race condition obviously, I was just curious,) I get another (possibly related) build failure as well: --------------------------------------------------------------------------- compiler/deSugar/DsMeta.hs:326:18: Constructor `FamInstD' should have 2 arguments, but has been given 1 In the pattern: FamInstD fi_decl In the pattern: L loc (FamInstD fi_decl) In an equation for `repInstD': repInstD (L loc (FamInstD fi_decl)) = do { dec <- repFamInstD fi_decl; return (loc, dec) } make[1]: *** [compiler/stage2/build/DsMeta.o] Error 1 --------------------------------------------------------------------------- I would assume someone forgot to push something perhaps, but I figured naturally someone should be aware so they can fix it. :) -- Regards, Austin
