Anyone else failing to validate on 'linker_unload'?

Building on Windows with msys
by Simon Peyton-Jones 04 Sep '13

04 Sep '13

Friends My Windows build (new laptop) got stuck again, but this time I managed to work out what is going on. This email is just to record the issue; I'll add something to the wiki. tl;dr: a MSYS build will fail in a deeply strange way if your MSYS bin directory doesn't take priority over the windows/system32 director. Symptom: "sh libtool" hangs indefinitely. The process manager shows an extant "cmd" and "sed", but nothing else. libtool is a shell script that comes from a tarball, and is unpacked into libraries/integer-gmp/gmp/gmpbuild/libtool Cause: libtool invokes the following command line (in the function func_convert_coer_msys_to_w32: cmd /c "echo blah" and pipes the result to sed. But MSYS mangles the command line to turn slashes into backslashes. So the actual command line is more like cmd \c "echo blah" which does something entirely different, and indeed hangs waiting for input on stdin. Solution: So how did this ever work on any MSYS installation? Because * msys/1.0/bin has a little script "cmd" which hands off to the real c:/windows/system32/cmd * MSYS does not mangle the command-line for programs in msys/1.0/bin * On my old laptop, msys/1.0/bin was in my path before c:/windows/system32. So plain "cmd" gets the script, and MSYS does not mangle the command line. The script passes arguments on unchanged to the real cmd. * NB: c:/windows/system32 is in the "system" path, which precedes the "user" path. So no amount of fiddling with the "user" path will fix this. There are two solutions: o Modify the system path o Use a .bashrc file to prepend the stuff you need This is pretty subtle stuff.

Hello, GHCi of GHC 7.7 use Unicode quote marks instead of ASCII quote marks. Why do you guys decide this behavior change? I'm just curious. --Kazu

New official language extension tokens for GHC 7.8.1
by Herbert Valerio Riedel 04 Sep '13

04 Sep '13

Hello GHC Devs, Which of the language extensions listed in `expectedGhcOnlyExtensions` in http://ghc.haskell.org/trac/ghc/browser/testsuite/tests/driver/T4437.hs#L33 are deemed ready for public consumption in GHC 7.8.1, and can be registered with upstream Cabal now (maybe even for the upcoming 1.18.0 release)?

RE: [Haskell-cafe] Announcing GHC iOS

Great. Please thank Stephen too.. I don't have his email.

And I'd be happy to take on maintainership of GHC iOS if that's what you mean - I've committed to a very large project using it so I'll be maintaining it anyway : ).

Three connected projects concerning cross-compilation: *Registerised ARM support, added using David Terei's LLVM compiler back end with Stephen Blackheath doing an initial ARMv5 version and LLVM patch and Karel Gardas working on floating point support, ARMv7 compatibility and LLVM headaches. Ben Gamari did work on the runtime linker for ARM. *General cross-compiling, with much work by Stephen Blackheath and Gabor Greif (though many others have worked on this). *A cross-compiler for Apple iOS. iOS-specific parts were mostly Stephen Blackheath with Luke Iannini on the Cabal patch, testing and supporting infrastructure, also with assistance and testing by Miëtek Bak and Jonathan Fischoff, and thanks to many others for testing; The iOS cross compiler was started back in 2009 by Stephen Blackheath with funding from Ryan Trinkle of iPwn Studios. Thanks to Ian Lynagh for making it easy for us with integration, makefile refactoring and patience, and to David Terei for LLVM assistance.

(in case you don't read /r/haskell : )) Stephen Blackheath and I are extremely happy to report that as of today, GHC can natively build binaries for iOS devices and the iOS Simulator. You'll find everything you need here: http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS The short of it is you can use "ghc-ios myFiles.hs" to get a universal ARMv7/ARMv7s/i386 static library to drop straight into an Xcode project. Stephen's already working on some wonderful FRP-powered games, I'm working on a project called SpaceTime that I'll announce shortly, and you may now all begin creating insanely great iOS software using the finest language in the world : ). Stephen deserves the lion's share of the credit for this project - it's been over 3 years in the making! Many thanks to Maxwell Swadling for generalizing static library builds into a -staticlib flag for GHC, Carter Schonwald for compilation guidance, and the venerable Austin Seipp for reviewing and merging our patches.
