"-c" is a bad option that conflates configuration and build, and leads to
this when certain kinds of configuration changes happen and alter the build
rules that are already running. Stop using "-c" and reconfigure properly
(./boot etc.). Yes, it's "convenient", right up until this happens. And
eventually this *will* happen, because configuration should not be done via
build rules.

Hi,
Suddenly I'm unable to build! As usual, I did:
git pull upstream master --recurse-submodules=yes git submodule update --init --recursive
$ hadrian/build.sh clean Up to date | Removing Hadrian files... | Remove directory _build/stage0 | Remove directory _build/stage1 | Remove directory _build/stage2 | Remove directory _build/stage3 | Remove directory sdistprep | Remove directory _build (after build completes) | Done.
... + statistics
$ hadrian/build.sh -c --flavour=devel2 -j2 Up to date | Running boot... Error when running Shake build system: at action, called at src/Rules.hs:68:19 in main:Rules at apply1, called at src/Development/Shake/Internal/Rules/Oracle.hs:159:32 in shake-0.18.2- fca156899176fbf7a9b05f30b3ec991784b3e60af38a503ea1cb277fd96f971e:Develo pment.Shake.Internal.Rules.Oracle * Depends on: OracleQ (KeyValue ("hadrian/cfg/system.config","host- os")) at need, called at src/Hadrian/Oracles/TextFile.hs:90:9 in main:Hadrian.Oracles.TextFile * Depends on: hadrian/cfg/system.config at &%>, called at src/Rules/Configure.hs:21:5 in main:Rules.Configure * Depends on: hadrian/cfg/system.config mk/config.h compiler/ghc.cabal rts/rts.cabal at apply1, called at src/Development/Shake/Internal/Rules/Oracle.hs:159:32 in shake-0.18.2- fca156899176fbf7a9b05f30b3ec991784b3e60af38a503ea1cb277fd96f971e:Develo pment.Shake.Internal.Rules.Oracle * Depends on: OracleQ (KeyValue ("hadrian/cfg/system.config","host- os")) * Raised the exception: Build system error - recursion detected: Key type: OracleQ KeyValue Key value: OracleQ (KeyValue ("hadrian/cfg/system.config","host- os")) Rules may not be recursive

Any ideas what's wrong??
