Blog post: Accessing the Keychain with MacRuby
by Carlo Zottmann 05 Feb '10

05 Feb '10

Hi guys, I got around building a wrapper around a C class in order to be able to access OSX' Keychain from MR. I hadn't done something like this before, so I thought it'd be a good idea to write it down. Maybe it'll help some other (Obj-)C newbs. ;) http://blog.zottmann.org/post/370827421/access-the-keychain-with-macruby Let me know what you think, or if I screwed up somewhere etc. All feedback welcome. Cheers, C. -- Carlo Zottmann Munich, Germany. -- http://carlo.zottmann.org TwerpScan -- Anti-Fool Twitter Contact Management Tool. http://twerpscan.com/

Macruby and serialport
by John-Paul Bader 04 Feb '10

04 Feb '10

Hey guys, i was recently playing around with Arduino / Microcontrollers and wrote a little script to make a hardware itunes volume control out of a potentiometer. Now would love to do that with macruby instead of this disgrace: http://github.com/hukl/Arduino-Experiments/blob/master/itunes_volume_contro… but unfortunately serialport won't work because auf the native extensions that don't work and IO which seems to be a bit buggy. Do you guys have any idea how to make macruby talk to the serial port or do i have to be a bit more patient ? ;) Kind regards, John

3 Questions, One about language restriction, one about platform targeting and the final about the standard library.
by Anthony Buck 04 Feb '10

04 Feb '10

Hi all, I have a couple of questions which I have attempted to answer to no-avail. I was wondering if anyone could point me in the right direction (Quite new to OS X development so my apologies if it is mealy my incompetence that has lead me here.) 1) I am looking into using MacRuby and am interested in it's ability to AOT compile ruby code down to an executable. I am wondering though whether this places a restriction on the code in any way? Is there a subset of ruby which is supported or can i go ahead and perform all the meta-magic i want and still have the code AOT compiled? 2) I am also interested in targeting both 10.6 and 10.5 with any applications developed (at 50%+ OS X share it is imposable to ignore with any conscience.) I have looked at the deployment task shipped with Mac Ruby and love the fact that I can have a simple .app to pass on to my users however, am i right in thinking that this .app will only operate on 10.6 machines? If so is there any way to develop either a combined or separate .app which is useful to users of 10.5? Is this possible when the development system is 10.6? 3) I also read an article about how the developer of Stopwatch* packaged said application without the "standard library." am I right in thinking that this is the ruby standard library which was left unpackaged? Wouldn't this render the application un-runnable? Any advice on any of the 3 questions is much appreciated. Regards, Anthony Buck * http://isaac.kearse.co.nz/2010/01/31/stopwatch/

Error building new LLVM revision
by Jordan Breeding 03 Feb '10

LLVM version: Path: . URL: https://llvm.org/svn/llvm-project/llvm/trunk Repository Root: https://llvm.org/svn/llvm-project Repository UUID: 91177308-0d34-0410-b5e6-96231b3b80d8 Revision: 89156 Node Kind: directory Schedule: normal Last Changed Author: dpatel Last Changed Rev: 89156 Last Changed Date: 2009-11-17 16:39:08 -0600 (Tue, 17 Nov 2009) I have tried building with a regular svn checkout, an archive created from git (through git-svn and `git svn find-rev`), and an archive created from the git repo on repo.or.cz (with the hash that matches the svn revision). Each time I get this error: llvm[2]: Compiling BlockProfiling.c for Release build (bytecode) /usr/bin/llvm-gcc -I/private/tmp/llvm-trunk/include -I/private/tmp/llvm-trunk/runtime/libprofile -I/tmp/llvm-trunk/include -I/tmp/llvm-trunk/runtime/libprofile -D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -O2 -fno-common -mmacosx-version-min=10.6 -pedantic -Wno-long-long -Wall -W -Wno-unused-parameter -Wwrite-strings -arch i386 -arch x86_64 BlockProfiling.c -o /private/tmp/llvm-trunk/runtime/libprofile/Release/BlockProfiling.ll -S -emit-llvm llvm-gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags make[2]: *** [/private/tmp/llvm-trunk/runtime/libprofile/Release/BasicBlockTracing.ll] Error 1 make[2]: *** Waiting for unfinished jobs.... llvm-gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags make[2]: *** [/private/tmp/llvm-trunk/runtime/libprofile/Release/BlockProfiling.ll] Error 1 make[1]: *** [libprofile/.makeall] Error 2 make: *** [all] Error 1 I know what the error is in general, but short of just building for x86_64, has anyone figured out a way to get the new LLVM revision building? Are the instructions in the README for MacRuby working for other people still? Thanks, Jordan
