Hi, I am trying to detect whether my process is being run in a debugger or not and, while in Windows there are many solutions and in Linux i use ptrace(PTRACE_ME,0,0,0) and check its return value, i did not manage to perform the same basic check on Mac Os X. I tried to use the `ptrace(PT_TRACE_ME,0,0,0)` call but it always retu...

Cocoa is well-documented and there is a lot of information on writing Cocoa code in good form. I'm working on some code that works closely with hardware, requiring me to use CoreFoundation and Carbon APIs often. Is there any sort of 'style' guide for understanding libraries such as Carbon and CoreFoundation from Apple? Apple's example...

Hello, I am trying to compile a static library on OSX 10.5 that links to a library that includes . The error message I'm getting is confusing because the conflicting type apparently conflicts with itself.

I'm running a GLFW app (that I wrote in C++) I run it as follows: ./prog.app/Contents/MacOS/prog # from the command line However, my code can't read relative-pathed files properly. So I believe what's happening is that this Mac Bundle is changing my current directory. 1) what does it change it to? 2) can I control this? Thanks! ...

I have looked for several hours for a good tutorial on how to store data for my command line program that I am writing in Objective-C. It seems like my options are NSUserDefaults, Plists, sqlite, or XML. Now, I think at most I'd have 50kb of data to store, retrieve, and modify, so it seems like from what I read Plists would work just f...

Hello, I'm trying to do image scaling using Core Image, using Lanczos Scale Transform filter. It is fine when I'm doing scaleup. But on scaledown and saving to JPEG I found a class of images which produces strange noise artifacts and behavior. For inputScale multiples to 0.5: 0.5, 0.25, 0.125 etc it is always fine. For others input...
It looks that OS X (10.6) does not generates codedumps by default. Using the ulimit -c unlimited is not a good solution because ulimit does set the limit in an environment variable. This will work only for console applications executed from the shell that executed ulimit. If you have a gui application this will not work. ...
Last version or XCode (3.2.1) is running very slow on OS X 10.6. What kinds of tweaks can you do to your Mac in order to speedup Xcode build process. I'm not looking for general hints like how to restructure your projects, just tweaks that are related to environment. For example I remember that on Windows for Visual Studio two signi...

Hello, I'm trying to build the boost libraries and others against the os x 10.4u.sdk so I can include them in a project targeting 10.4 upwards. I'm not entirely sure what to do, am I aiming to put the .dylibs in 10.4.sdk/usr/local/.. or in my default 10.6 /usr/local/.. with support for 10.4? Any help much appreciated. Toby. ...
