Hello Yhc'ers, I have just updated (darcs pull'ed) my regular yhc installation, scons fullclean'ed and then scons type=release --config=force'd. This is the result: ... Compiling YHC.Internal ( src/packages/yhc-base-1.0/YHC/Internal.hs ) Copy("inst/lib/yhc/packages/yhc-base/1.0/YHC/Internal.hi", "src/packages/yhc-base-1.0/YHC/Internal.hi") YHC_build(["src/packages/yhc-base-1.0/System/Exit.hbc"], ["src/packages/yhc-base-1.0/System/Exit.hs"]) inst/bin/yhc -core -cpp -c src/packages/yhc-base-1.0/System/Exit.hs yhc: Error: Found file multiple times, YHC.Exception Reason: imported from System.Exit Found in: scons: *** [src/packages/yhc-base-1.0/System/Exit.hbc] Error 1 scons: building terminated because of errors. Interestingly, my buildbot compiles fine. I can, of course, start all over, but perhaps you would like to inject a comment first? And note: The message "Found file multiple times" actually means "Not found", as far as I have been able to tell The wording of this particular message is the subject of a bug report that I was preparing when this other thing hit. Best regards Thorkil
