traverse_
by Kazu Yamamoto 30 Mar '15

30 Mar '15

Hi, I have just installed GHC 7.10.1. I'm a little bit surprised because 'traverse_' is not exported from Prelude. But 'traverse' is exported. Is this intentional? I expected that I can forget xxxM, xxxM_, xxxA, and xxxA_ functions with GHC 7.10.1. I want to use 'traverse_' instead of 'mapM_'. --Kazu

HP 2015.2.0.0 and GHC 7.10
by Randy Polen 30 Mar '15

30 Mar '15

I am helping Mark with the Haskell Platform, doing the Windows builds (32- and 64-bit). I want you to be aware of a problem I am encountering, and solicit suggestions and possible help. In building for HP 2015.2.0.0 on Windows 7, 64-bit (haven't gotten to 32-bit yet but likely the same problem will occur), I seem to be hitting the 32K limit for the length of arguments to a process, encountered while cabal is invoking haddock to build the docs for the OpenGLRaw package. For HP2014.2.0.0, the argument list was ~25K (from looking at my old build logs) but now is ~36K, which exceeds the maximum for CreateProcess (not a limit of the command-line, but of the OS call itself). Is there a way to build haddock docs for a single package but in multiple haddock invocations (maybe building a .haddock file for portions, then combining them, with the goal that the command line is kept short)? Seems this would also require a corresponding cabal change, as cabal is the invocator when this happens. Barring any existing mechanism, the typical solution to this problem on the Windows OS is (when possible, of course) to modify the program to accept a "response file" of command-line arguments. In this case, we could add an option to haddock to accept either a complete "response file" (i.e., allowing *all* options and arguments to come from a file) or just a file containing the files to process. Either of these changes to haddock are rather trivial to write (but adding another option implies more testing, documentation, other cases to handle, etc.). Since haddock ships with the ghc release, that's another wrinkle for this particular release. The other implication of such a solution is that cabal would need a change to utilize this change for it to be effective, checking haddock's version for support of this new haddock-flag, and either use it if the haddock version supports it, or do it optionally (which implies a new flag for cabal's haddock sub-command). This change to cabal is also rather trivial to implement (this is not to imply insensitivity to the incurred cost of each line of code, nor to the added burden of user-visible changes such as a command-line option). (Less desirable possibilities, mentioned only for completeness: skip the documentation for OpenGLRaw for this version of the Haskell Platform; split up the OpenGLRaw package itself in some way.) Other possible solutions and work-arounds? Thoughts on either using haddock in a different way (and the cabal change that would be required to break up the doc build into multiple steps for a single package)? Thoughts on the "response file" solution? Randy

Platform 2015.2.0.0 Alpha 2 for debian based systems
by Mark Lentczner 30 Mar '15

30 Mar '15

I've uploaded a build of *Haskell Platform 2015.2.0.0 Alpha 2* for generic debian linux systems. It includes GHC 7.10.2, using the generic linux bindist. This is a tarball, not a package. Installation instructions: cd / sudo tar xvf ...downloaded-tarfile... sudo /usr/local/haskell/ghc-7.10.1-x86-64/bin/activate-hs Notes: - Built on Ubuntu 14.04LTS - Needs the following packages installed: build-essential libbsd-dev libgmp-dev libtinfo-dev zlib1g-dev - The OpenGL packages need the OpenGL libs, which on a non-GUI system like a server can be gotten by installing: freeglut3-dev libgl1-mesa-dev libglu1-mesa-dev - Mark

OS X builds of GHC 7.8.4, 7.10.1-rc2, and 7.10.1-rc3
by Miëtek Bak 29 Mar '15

29 Mar '15

An OS X build of GHC 7.10.1-rc3 is now available, courtesy of Mark Lentczner. This is in addition to the GHC 7.8.4 and 7.10.1-rc2 builds Mark has made available on February 2. Thanks, Mark. GHC 7.8.4 for OS X can already be downloaded from haskell.org, even though it’s not mentioned on the GHC 7.8.4 webpage: https://downloads.haskell.org/~ghc/7.8.4/ghc-7.8.4-x86_64-apple-darwin.tar.… To avoid running up Mark’s bandwidth bill, I’m omitting the URL to his staging area. I’ve mirrored all three builds in Halcyon public storage: 7.8.4: https://halcyon.global.ssl.fastly.net/original/ghc-7.8.4-x86_64-apple-darwi… 7.10.1-rc2: https://halcyon.global.ssl.fastly.net/original/ghc-7.10.0.20150123-x86_64-a… 7.10.1-rc3: https://halcyon.global.ssl.fastly.net/original/ghc-7.10.0.20150316-x86_64-a… Binary builds of GHC, repackaged with documentation removed, are also available in Halcyon — on OS X 10.10, 10.9, 10.8, and a considerable number of Linux distributions. This includes GHC 7.10.1-rc3, 7.10.1-rc2, 7.8.4, 7.8.3, 7.8.2, 7.6.3, 7.6.1, 7.4.2, 7.2.2, and 7.0.4. Using Halcyon, installing GHC together with cabal-install is expected to take 20-30 seconds: https://halcyon.sh/tutorial/#install-ghc-and-cabal -- Miëtek https://mietek.io

Automating GHC build for Windows
by Roman Kuznetsov 29 Mar '15

29 Mar '15

Hello *, As I am still new in this, I will ask. Were there any attempt to automate GHC build process on Windows with some kind of CI engine, like Hudson, Jenkins, etc.? It seems to be rather helpful to publish build results if not after each commit, but at least once every day. WDYT? -- Sincerely yours, Roman Kuznetsov

Verfied that the upload of the ghc bindist was cut short. New upload in progress! I've double checked and the build of Platform, and it's upload is fine.

I have built the 7.10.1 bindist for OS X. It is currently sitting on my server at: ghc-7.10.1-x86_64-apple-darwin.tar.bz2 <http://www.ozonehouse.com/mark/platform/ghc-7.10.1-x86_64-apple-darwin.tar.…> \O/ I have built an Alpha 2 of Haskell Platform 2015.2.0.0 for OS X <http://www.ozonehouse.com/mark/platform/Haskell%20Platform%202015.2.0.0%20a…>. It is based on the above bindist. I should have an ubuntu version of the Platform built by tomorrow. \O/ - Mark *sha256 sums:* c6eb8d573538eba27dfb2d9acf52a1beaaa512208261528b91e8d1775d133eee ghc-7.10.1-x86_64-apple-darwin.tar.bz2 0cb351281fcf5ef34c54b455a3643d0ff078299a53b2c39d911dbda4aac2d233 Haskell Platform 2015.2.0.0 alpha 2 64bit.pkg

Alas, for me during the week I'm swamped with work (a good thing - it means my project there is going very well!) If this sync'ing with GHC releases path is well received, then next time we'll have a bit more (~1 month) runway! - Mark
