Can you try with the "--no-ghc-package-path" option in your wrapper? Matt On Thu, Jan 26, 2017 at 10:22 AM, Marius Ghita wrote:

I use "export PATH=`stack path --bin-path`" to make the stack installed ghc available in the PATH before building ghc. And that's all. Setting the PATH works better because we do not get any extra env variables set by stack in the environment and we do not go through the stack wrapper, so it may be a little bit faster as well. The GHC_PACKAGE_PATH variable set by the stack command is especially troublesome in some cases. You can try "stack exec env" to check all vars that stack puts in your environment. -harendra On 26 January 2017 at 15:52, Marius Ghita wrote:

Can I ask a silly question. I can't seem to find where stack is recommended for ghc development on the newcomers page, but why is it? I don't want to start another flame war but I can't imagine any scenario where this is useful. As far as I understand the whole benefit of stack is the curated packages. Which are moot here since almost everything you need is in the tree aside from Happy and Alex. Seems to me this is just overcomplicating a very simple process. Not to mention if you have to go through stack - - exec etc all for interactions with the build artifacts it would get old quickly. Also it doesn't seem reliable especially if stack is modifying the environment and or flags passed to the compiler. Let me reiterate, I have nothing against stack, I just don't see the benefits here. Ideally you'd want your environment as simple and vanilla as possible and *totally* in your control IMHO. What am I missing here? Thanks, Tamar On Thu, 26 Jan 2017, 14:21 Harendra Kumar, wrote:

I think the intention is that if you are already using stack to manage your GHC installations then it is desirable to use their managed version of GHC rather than have to install another version. It seems to me that the solution that Harendra suggests is the easiest for anyone with this setup. Fwiw, the easiest way I found to setup a clean development environment for GHC was to use the nix ghcHEAD derviation. nix-shell '<nixpkgs>' -A haskell.compiler.ghcHEAD but of course, this only works if you are using nix!

But do you really want to do this? It seems to me you don't want to keep using your stage0 while working on ghc. As you don't want to break it and spend hours wondering why your build failed. Fair enough, if people want to do this. So long as it's not the defacto method. On Thu, 26 Jan 2017, 17:28 Matthew Pickering, wrote:

Thank you all for the feedback, I went with Harendra's solution and that worked fine (and removed any shell wrapping I had to do). To answer Phyx, using stack has become more convenient for managing ghc than using the packages my distro offers (which always falls behind the latest version of GHC by a couple of months), or the alternative of just downloading binaries and managing that process manually. There might also be a misunderstanding given your first post, because I only use stack to provide those ghc (ghc-pkg, alex, happy) binaries, and I'm not managing the ghc source as a stack package; and what that means is that I don't have to run `stack exec --` to interact with build artifacts.
