Dear GHC team, For some reason ghc-7.4.1-unregisterised cannot build random-1.0.1.1 -- unlike ghc-7.4.1-default. This is for ghc-7.4.1 built from source by ghc-7.4.1 on Debian Linux, i386-uknown. 1. I build ghc-7.4.1 from source under the default flags, by ghc-7.4.1, under configure --prefix=/home/mechvel/ghc/7.4.1/inst 2. Build ghc-7.4.1 from source by new by ghc/7.4.1/inst as unregisterised by setting configure --prefix=/home/mechvel/ghc/7.4.1/instUnregis , ----------- setting BuildFlavour = unreg in mk/build.mk by un-commenting this line. 3. Build random-1.0.1.1 by ghc of 7.4.1/inst by ghc --make Setup ./Setup configure --prefix=/home/mechvel/ghc/7.4.1/inst/lib/ghc-7.4.1 -p ./Setup build -v ./Setup haddock ./Setup install -v It is built all right. 4. Build random-1.0.1.1 by new by ghc/7.4.1/instUnregis by ghc --make Setup ./Setup configure --prefix=/home/mechvel/ghc/7.4.1/instUnregis/lib/ghc-7.4.1 -p ./Setup build -v It reports ----------------------------------------------------------------------- scico:~/ghc/random/random-1.0.1.1> ./Setup configure --prefix=/home/mechvel/ghc/7.4.1/instUnregis/lib/ghc-7.4.1 -p Configuring random-1.0.1.1... scico:~/ghc/random/random-1.0.1.1> ./Setup build -v creating dist/build creating dist/build/autogen Building random-1.0.1.1...
