Yes there is. In your build.mk, set GhcLibWays = p This is discussed a lot in the Building Guide, which I commend to you if you are building GHC.

Is there a good strategy for building both regular and profiling variants of libraries? One of the problems is that the .hi files are not compatible, so I need to both kinds of those too. Should I be giving them separate names or something? How do people deal with this? Right now I do a 'make clean' and then rebuild with profiling options, but that's kind of annoying... -- Ashley Yakeley, Seattle WA

| Aha. So how will GHC find all the various module imports? You install the package using ghc-pkg. That tells GHC where it is. Simon

| newtype Foo = Foo Int deriving (Num) | instance Show Foo where { show = undefined } | | then, the value of 'show (Foo 5)' is undefined, but the value of 'show | (5::Foo)' is "5". definately *WRONG*. You're right. This is all a bit more complicated than I (or John H) thought. Thinking cap on. But don't hold your breath. Simon

I'd rather be using "-package foo" than "-i/usr/local/share/foo/haskell/imports". Or is there going to be some standard, official place for everyone's .hi files to be installed in, such as the GHC imports directory? -- Ashley Yakeley, Seattle WA

Definitely not. Packages are the unit of distribution, and the unit of library archive, in GHC. If you import a module Foo, GHC has to figure out which libBaz.a to link.

Seeking clues
by mgross＠dorsai.org 07 Oct '02

07 Oct '02

I have now made several failed attempts to compile various versions of the fptools package with parallel support (way=mp). The Debian packages I have tried come in without the _mp libraries, and all of the different variations I have tried on building from source have failed with nasty errors during make. Thus: Have any of the readers here gotten one of the source packages available from Haskell.org to build with parallel support? Would ya' be good enough to give me the clues so I can repeat your success and be forever grateful? Thanks, Murray Gross

Is the "-package-name" mechanism still worthwhile now that we have hierarchical modules? -- Ashley Yakeley, Seattle WA
