Can't build current HEAD
I am unable to build current HEAD. I'm getting a build error in Outputable module: compiler/utils/Outputable.hs:1046:28: Not in scope: type constructor or class ‘CallStack’ compiler/utils/Outputable.hs:1047:23: Not in scope: ‘showCallStack’ The most likely culprit is 80d7ce8038a100f6797a89755c893c6f67f18a30, which added this: #if __GLASGOW_HASKELL__ >= 710 pprSTrace :: (?location :: CallStack) => SDoc -> a -> a pprSTrace = pprTrace (showCallStack ?location) #else pprSTrace :: SDoc -> a -> a pprSTrace = pprTrace "no callstack info" #endif The most interesting thing is that if I change the definition of pprSTrace in the first branch of #if to be identical to the definition in the second branch, then I get warnings that GHC.Stack and GHC.Exception imports are redundant. Any ideas what might be going on here? I'm compiling using GHC 7.10.1. This happens in a clean build tree.

I just verified this does not happen when building with GHC 7.8.4, so if our build machines (harbormaster, travis) are building using 7.8.4 this might not show up in the logs. Janek Dnia piątek, 13 listopada 2015, Jan Stolarek napisał:

The most likely culprit is 80d7ce8038a100f6797a89755c893c6f67f18a30, which added this:
#if __GLASGOW_HASKELL__ >= 710 pprSTrace :: (?location :: CallStack) => SDoc -> a -> a pprSTrace = pprTrace (showCallStack ?location) #else pprSTrace :: SDoc -> a -> a pprSTrace = pprTrace "no callstack info" #endif
The most interesting thing is that if I change the definition of pprSTrace in the first branch of #if to be identical to the definition in the second branch, then I get warnings that GHC.Stack and GHC.Exception imports are redundant.

I just ran into this myself. The ">= 710" is wrong, since 7.10 does not have CallStack yet. Changing it to "> 710" lets you compile GHC again, at the cost of a redundant import warning.
