Yes, as you stated, not an HP problem. I did a cabal update and got past this problem. I still can't install threadscope but I don't believe this is an HP platform problem so I'll follow up with the threadscope people and won't post again to this group Thanks [10 of 35] Compiling GUI.ProgressView ( GUI/ProgressView.hs, dist/build/threadscope/threadscope-tmp/GUI/ProgressView.o ) GUI/ProgressView.hs:92:15: Could not deduce (System.Glib.UTFString.GlibString string0) arising from a use of ‘labelNew’ from the context (WindowClass win) bound by the type signature for new :: WindowClass win => win -> IO () -> IO ProgressView at GUI/ProgressView.hs:79:8-57 The type variable ‘string0’ is ambiguous Note: there are several potential instances: instance System.Glib.UTFString.GlibString text-1.1.0.0:Data.Text.Internal.Text -- Defined in ‘System.Glib.UTFString’ instance System.Glib.UTFString.GlibString [Char] -- Defined in ‘System.Glib.UTFString’ In a stmt of a 'do' block: progText <- labelNew Nothing In the expression: do { win <- windowNew; set win [containerBorderWidth := 10, windowTitle := "", ....]; progText <- labelNew Nothing; set progText [miscXalign := 0, labelUseMarkup := True]; .... } In an equation for ‘new’: new parent cancelAction = do { win <- windowNew; set win [containerBorderWidth := 10, ....]; progText <- labelNew Nothing; .... } cabal: Error: some packages failed to install: threadscope-0.2.4 failed during the building phase.

Installation worked fine. However I encountered a problem that looks like a regression, although it may be a problem with new versions of the package I am trying to install:

It's not an H-P problem; Apple's started using their BLOCKS C extension in system headers, and gtk2hsc2hs doesn't understand it. (And possibly is not using cpp properly when processing headers.) You'll need to take this up with the gtk2hs folks.

#ifdef __BLOCKS__ int scandir_b(const char *, struct dirent ***, int (^)(const struct dirent *), int (^)(const struct dirent **, const struct dirent **)) __DARWIN_INODE64(scandir_b) __OSX_AVAILABLE_STARTING(__MAC_10_6, __ IPHONE_3_2); #endif /* __BLOCKS__ */
