Re: [Haskell-iPhone] More arm-apple-darwin10-ghc trouble

It looks like nuking jobs: $ncpus did the trick. I now have primitive and vector installed and confirmed with arm-apple-darwin10-ghc. After building my static lib the next issue is that I'm having a lot of linking errors in Xcode. Here is the build log: https://gist.github.com/schell/f10af8c0d29e24da5c25 On Sun, Dec 22, 2013 at 4:47 PM, Luke Iannini wrote:

Hey Schell,

I think I see the issue — did you see the note in section 6 of https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOSregarding the jobs: $ncpus option in ~/.cabal/config ? If you've got that, nuke it and see if that fixes it.

I need to file a bug about that with the Cabal team.

I've also been meaning to warn — I am pretty sure the fat armv7s/armv7 binary approach taken by arm-apple-darwin10-ghc doesn't fully work yet (I was convinced it did when I implemented it, but recent testing with armv7 and armv7s devices show missing symbols for one arch or the other). I haven't had nearly the time to work on it and if anyone's looking for a way to help with GHC iOS that's a great self-contained problem to work on : ).

If we can't get that approach to work (intercepting build commands and lipoing things together on the fly), there's always the approach of building one GHC for each armv7 and armv7s, but that's got its own pain points since GHC calls both of those just "arm" internally and you have to do some yucky stuff with directory management :/ (that's what I've done here, and it works at least : )).

Hopefully I'll be out of the woods in my primary work soon and able to devote more cycles help in cleaning these things up.

Cheers Luke

The primitive log is empty, nothing is printed to it. The version of vector I'm trying to build is 0.10.9.1, which is currently on hackage. I've also tried building primitive 0.5.2.0 by hand - cloning it from github and then running arm-apple-darwin10-cabal install and it stops at the same error. Nothing is printed to the log file. If I try each step separately (configure, build, install) I can configure fine and building gives this output:

And then installing gives:

cabal: Error: some packages failed to install:

To me it seems like the line "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive library: dist-arm/build/libHSprimitive-0.5.2.0.a will be fat and ar(1) will not be able to operate on it" could be important? Does that sound like it may have something to do with the install failure?

Oooooo. What version of vector are you using? It needs to be the one for ghc HEAD.

Could you also share the primitive log? Seems like something is happening there. Can't you just build primitive by hand then vector?

Ah, cool - I didn't know that the verbosity arg took a parameter. Here is the full output: https://gist.github.com/schell/7c08631f52e1e6f54a39

The -v flag is for cabal. Be sure to post a link to the full output.
