"unknown required load command"
by Alistair Holt 26 Dec '09

26 Dec '09

Hello, I've just finished going through the Meet MacRuby video from PeepCode and making the example Twitter client app. When I tried to build and distribute a release of the app to my friend (on Mac OS X 10.5.8) all he got were crashes and errors when he tried to open it. An example of the errors logged to the console can be found at https://gist.github.com/21f82c11499e0da754e5. I built the app for 10.5 x86_64 with MacRuby embedded. Does anyone have any ideas what the issue might be? Thanks Alistair Holt E: alistairholt(a)gmail.com W: alistairholt.co.uk / http://www.linkedin.com/in/alistairholt

[MacRuby] #521: Float problem with 8.1 and 9.1

#521: Float problem with 8.1 and 9.1 ------------------------------------+--------------------------------------- Reporter: macruby@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: ------------------------------------+--------------------------------------- MacRuby 0.5b2 seems to have a problem with the floats 8.1 and 9.1. Here is what 'macirb' does: irb(main):005:0> 9.1 => 9.09999999999999 irb(main):006:0> 8.1 => 8.09999999999999 I get the same results from 'macruby'. The strange thing is that if I do the following: irb(main):007:0> 9.1 + 1 => 10.1 irb(main):008:0> 10.0 - 0.9 => 9.09999999999999 very strange - AYAL -- Ticket URL: <http://www.macruby.org/trac/ticket/521> MacRuby <http://macruby.org/>

Some OpenGL sample code
by Julien Jassaud 24 Dec '09

24 Dec '09

Hello to everyone, I tried to port two OpenGL sample code examples from the ADC in MacRuby ( and plan to port some more ). You can find both projects here : http://github.com/sojastar Both kind of work but have problems I can't find solutions to so I turn to the list for a little help. One of the examples ( MacRuby-BoingX ) randomly crashes, either on launch or exit, about one time out of five. When launching the application from XCode, I get : Program received signal: “EXC_BAD_ACCESS”. which suggests a memory access error. It is not unlikely since the OpenGL functions use a lot of pointers. I am trying to use DTrace to identify the problem but it is very new territory for me. I wrote a script returning the name of the last function called. I get a different result for every crash. I imagine part of my data ( most often, the vertex data ) must be corrupted, and maybe from the various pointer operations I have to do to use OpenGL. Has anyone any suggestion on how I could troubleshoot such a problem ? The problem with the second example is directly related to pointers. The function CGLQueryRendererInfo function expects a pointer to a CGLRendererInfoObj object as its second argument. After the call, the pointer points to a valid CGLRendererInfoObj object. So I did something like this : renderer_info = Pointer.new_with_type("^{_CGLRendererInfoObj}") renderer_error = CGLQueryRendererInfo(display_mask, renderer_info, renderer_count) and get : expected instance of Pointer of type `^{_CGLRendererInfoObject}', got `^{_CGLRendererInfoObj}' (TypeError) If I change the pointer type to '^{_CGLRendererInfoObject}', CGLQueryRendererInfo doesn't complain anymore, but all other following functions using the CGLRendererInfoObj do. Could this be a bridge support problem ? As anyone who has a better background in Cocoa any idea ? I know some things should be done in bundles but, for sample code, I thought it would be good to try to go Ruby all the way. My configuration : Intel Core 2 Duo MacBook Pro, Mac OS 10.6.2, MacRuby 0.5b2 Thanks, Julien Jassaud
