When I downloaded and unpacked the latest GHC snapshot of the STABLE branch for Windows (ghc-6.4.2.20060421-i386-unknown-mingw32.tar.gz), I got the following error trying to start GHCi: ___ ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 6.4.2, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help. Loading package base-1.0 ... linking ... : c:/ghc/GHC-64~1.2/HSbase1.o: unknown symbol `_sqrtf' : unable to load package `base-1.0' ___ The complaint about _sqrtf also shows up when I try to compile/link anything with ghc; so the problem is bigger than just not being able to use GHCi. The GHC is installed in c:\ghc\ghc-6.4.2, the PATH begins with c:\ghc\ghc-6.4.2;c:\ghc\ghc-6.4.2\bin;c:\ghc\ghc-6.4.2\gcc-lib; LIBRARY_PATH is set to c:\ghc\ghc-6.4.2\gcc-lib I know for sure that the 6.4.2 snapshot of a couple of weeks ago worked fine, so I wonder what might be wrong with the latest one. I would appreciate any hints. Cheers, Cyril
