Herbert,
It's done!
Thanks. I tried to build GHC HEAD on Mac. I did: % git clone git://git.haskell.org/ghc.git % cd ghc % ./sync-all get % CPUS=10 sh validate Unfortunately, I got the following errors: ---- "inplace/bin/ghc-stage1" -optc-m64 -optc-fno-stack-protector -optc-Werror -optc- Wall -optc-Ilibraries/unix/include -optc-I'/Users/kazu/work/ghc/libraries/time/i nclude' -optc-I'/Users/kazu/work/ghc/libraries/bytestring/include' -optc-I'/User s/kazu/work/ghc/libraries/base/include' -optc-I'/Users/kazu/work/ghc/libraries/i nteger-gmp/include' -optc-I'/Users/kazu/work/ghc/rts/dist/build' -optc-I'/Users/ kazu/work/ghc/includes' -optc-I'/Users/kazu/work/ghc/includes/dist-derivedconsta nts/header' -optc-Wno-unknown-pragmas -static -H32m -O -Werror -Wall -H64m -O0 -package-name unix-2.7.0.1 -hide-all-packages -i -ilibraries/unix/. -ilibrari es/unix/dist-install/build -ilibraries/unix/dist-install/build/autogen -Ilibrari es/unix/dist-install/build -Ilibraries/unix/dist-install/build/autogen -Ilibrari es/unix/include -optP-include -optPlibraries/unix/dist-install/build/autogen/cabal_macros.h -package base-4.7.1.0 -package bytestring-0.10.4.0 -package time- 1.4.2 -Wall -XHaskell2010 -O2 -O -dcore-lint -fno-warn-deprecated-flags -no-use r-package-db -rtsopts -c libraries/unix/cbits/dirUtils.c -o libraries/unix/ dist-install/build/cbits/dirUtils.o libraries/ghc-prim/cbits/atomic.c:108:10: error: implicit declaration of function '__sync_fetch_and_nand' is invalid : libraries/ghc-prim/cbits/atomic.c:108:10: note: did you mean '__sync_fetch_and_and'? libraries/ghc-prim/cbits/atomic.c:78:10: note: '__sync_fetch_and_and' declared here return __sync_fetch_and_and(x, (StgWord8) val); ^ 1 error generated. ---- I think that I could validate GHC HEAD yesterday. --Kazu
