make html

Dear GHC supporters, I have made ghc-6.4 from source by binary itself (Linux, Debian 3.1): cd ghc/6.4/ghc-6.4/ ./configure --prefix=foo make make install But it is so hard to obtain documentation! I tried make html (in the same directory). It reports ------------------------------------------------------------------------ ===fptools== Recursively making `html' in glafp-utils ghc libraries hslibs docs ... PWD = /home/mechvel/ghc/6.4/ghc-6.4 -- ... ... rm -f -rf users_guide/ stringparam base.dir users_guide/ \ --stringparam use.id.as.filename 1 \ --stringparam html.stylesheet fptools.css \ --stringparam toc.section.depth 3 --stringparam section.autolabel 1 --stringparam section.label.includes.component.label 1 \ /html/chunk.xsl users_guide.xml make[3]: stringparam: Command not found ... ************************************************************ The user has managed to make GHC: a big deal. And now has problems with making docs. This looks strange. Why not provide, say, a couple of ready .ps files for user guide and library guide? And if it is .html, let them be ready .html files. ? With kind regards, ----------------- Serge Mechveliani mechvel(a)botik.ru

Simplifier output explanation needed
by Jens Fisseler 01 Jun '05

Hi everbody! I'm currently trying to optimize some code, in particular trying to make some functions as strict as possible. To do this, I quite often look for strictness annotations either in the interface files or the the simplifier output. Doing this, something odd occured to me: inserting a '$!' into a function call, trying to enforce eager evaluation, the simplifier output changed. Ok, I should expect this, but I don't understand the change. The function name got '$s' as a prefix and the strictness annotation ('Str: DmdType SSL') vanished. So my question is what all those different prefixes mean. I've stumbled across at least '$s' and '$w' (worker wrapper?). Why did the strictness annotation disappear? Is there any documentation that can enlighten me? Regards, Jens

Hello Fergus, Tuesday, May 31, 2005, 10:24:41 PM, you wrote: >> import Data.Set hiding (map) >> import qualified Data.Set as Set >> >> will do fine. FH> That code only compiles with ghc 6.4, and won't compile with ghc 6.2: FH> you'll get an error for the "hiding (map)" part, because in 6.2 FH> Data.Set does not contain a "map" function. btw, question to Simon Marlow and Simon PJ - how about disabling this error message? -- Best regards, Bulat mailto:bulatz@HotPOP.com
