Re: [Haskell-cafe] cabal-dev: installing/running with profiling enabled
Hi Rogan, Thanks for your reply. I don'th think the -prof flag is necessary; but if it is, then it may also be misinterpreted by cabal-dev; generally, you need to pass flags that only use a single leading - to cabal-dev with the --flags=... option. (eg: 'cabal-dev install --enable-library-profiling --enable-executable-profiling --flags=-prof' This command worked for me: $ cabal-dev install --enable-library-profiling --enable-executable-profiling OK, so I removed `cabal-dev` directory, and installed again with this command. But it still failed with same error message(the flag -p requires the program to be built with -prof). Then I also tried removing cabal-dev again and installing again but this time with extra `--flags=-prof` parameter. Failed with same error. Just to be sure I created a new cabal project with only one file: 'Hello.hs' with contents 'main = putStrLn hello' and tried to install it with cabal-dev. And `./cabal-dev-/bin/Hello +RTS -p` failed with same error again. Maybe something wrong with my system? My first thought was maybe cabal-dev is using some pre-installed library, and it's not recompiling the whole world for each sandbox. But I don't know how to check this. Any ideas on that?

Maybe you are running into this: https://github.com/haskell/cabal/issues/1199 Check your version of the Cabal library (cabal --version should tell you). I think this was only broken for a few releases, but I don't remember which ones. pgp4n6mPD4Zps.pgp Description: PGP signature ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Maybe you are running into this: https://github.com/haskell/cabal/issues/1199 Check your version of the Cabal library (cabal --version should tell you). I think this was only broken for a few releases, but I don't remember which ones. Great, it worked. I first updated Cabal library (with `cabal install cabal`) and cabal-install program(`cabal install cabal-install`) and then reinstalled cabal-dev. Now it works for my hello world program. Hopefully it will also work with my main program(it's compiling now, and it will take some time).

[Haskell-cafe] cabal-dev: installing/running with profiling enabled
Hi all, I want to profile a Haskell program. I have tons of libraries installed without profiling enabled, and some of them are installed with my Linux distribution's package mangaer. So I tried installing the program in a fresh cabal-dev environment with profiling enabled, so that all dependencies would be also installed with profiling enabled. But for some reason even after installing with `cabal-dev install --enable-executable-profiling -prof` I still can't run this program with `caba-dev/bin/program +RTS -p`, it fails with 'program: the flag -p requires the program to be built with -prof'. Can anyone help me on installing/running in cabal-dev with profiling enabled? --- Ömer Sinan Ağacan http://osa1.net ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi Ömer, I've replied in-line below.

Because you're installing libraries (into the cabal-dev sandbox) you'll also need to add the --enable-library-profiling flag, in addition to the --enable-executable-profiling flag. Cabal-dev could infer the former from the later, but we haven't done that (this doesn't seem to come up very often).
