Hello, This is supposed to work, and worked for a while until some refactoring of mine which mistakenly dropped some logic. Matthew fixed it as soon as he noticed it though, so I suspect your branch doesn't have https://gitlab.haskell.org/ghc/ghc/commit/cfe64019a70acc1bae76f2fa580d6654f8... ? Cherry-picking this commit or rebasing against a quite recent master should fix the issue. Sorry for the inconvenience. On 25/01/2019 14:28, Andreas Klebinger wrote:

Hello Devs,

What's the proper way to get a profiled GHC in hadrian?

I tried

  hadrian/build.cabal.sh -j8 --flavour=Prof

but that didn't work out:

  $ _build/stage1/bin/ghc.exe +RTS -p   ghc.exe: the flag -p requires the program to be built with -prof   ghc.exe:   ...

What am I doing wrong here?
