This morning I was successfully running BlazeHtml on Windows 7. Then I installed some libraries from other packages and BlazeHtml broke. I then decided to go from ghc 6.12.1 to ghc 7.0.3 and reinstall everything. BlazeHtml installed OK. But my program also needed ByteString. So I did the following: First I tried the stable version:
cabal install bytestring-0.9.1.4
Resolving dependencies... Configuring bytestring-0.9.1.4... Preprocessing library bytestring-0.9.1.4... Building bytestring-0.9.1.4... Data\ByteString.hs:3:24: Cannot parse LANGUAGE pragma Expecting comma-separated list of language options, each starting with a capital letter E.g. {-# LANGUAGE RecordPuns, Generics #-} cabal: Error: some packages failed to install: bytestring-0.9.1.4 failed during the building phase. The exception was: ExitFailure 1 I am not experienced enough to fix this, so I tried a previous ByteString version:
cabal install bytestring-0.9.1.3
Resolving dependencies... Configuring bytestring-0.9.1.3... Preprocessing library bytestring-0.9.1.3... Building bytestring-0.9.1.3...

The exception was: ExitFailure 1 No joy. Help appreciated. May try all this on my MAC tomorrow. Ralph Hodgson, http://twitter.com/ralphtq @ralphtq Mobile Phone: +1 781-789-1664
