People,

I need help on making for profiling, and cannot decide whether the question is on GHC or on Cabal.

I have ghc-6.4.1, and Cabal-1.1.3-September-12 installed in my user directory, under Debian Linux, and need to make a project for profiling.

ghci -package Cabal says ... Loading package base-1.0 ... linking ... done. ... Loading package Cabal-1.1.3 ... linking ... done.

I start with a contrived example project of M1.hs, M2.hs, Main.hs:

--------------------------------------- module M1 where m1 = True

module M2 where import M1; m2 = m1 && m1

Main.hs: import M2l; main = putStr $ shows m2 "\n" ---------------------------------------

For this, ghc --make -prof -auto-all Main

works as needed -- without packages. Now, try to make a package for profiling:

foo.cabal: name: foo version: 1.0 build-depends: base, haskell98, data exposed-modules: M2 other-modules: M1 ghc-options: -prof -auto-all -hisuf p_hi -osuf p_o

The aim is to build foo (of M2) as a library, then to make Main under the package foo, and with profiling.

Then, runhaskell Setup configure --ghc --prefix=$source/inst runhaskell Setup build

produces a report

The directory ~/t/dist/build contains at this moment

M1.p_hi M1.p_o M2.p_hi M2.p_o Main.p_hi Main.p_o

, and indeed, no M2.o file.

If I remove -hisuf p_hi -osuf p_o

(by the way, why should the user think of these wise suffixes, maybe, -prof should be sufficient? ), then it reports ... /usr/bin/ld: cannot find -lHSfoo-1.0_p collect2: ld returned 1 exit status

What I am missing, please? Thank you in advance for the help.

You don't have to mess with GHC-Options at all. Just pass --enable-library-profiling to the setup script when you're configuring the library. -- Friendly, Lemmih
