I am using os X 10.3.9 with gcc version 3.3. I am trying to compile a
small code that I have written. This code uses a library written in c,
called lp_solve. The header file "lp_lib.h" for this library has the
following piece of code:

In porting a Windows game to MacOS, I've noticed that there is a
number of ways to do the same things.  Ultimately, I want to end up
using native methods whereever possible.
My build environment is Scons and GCC, not Xcode.  Answers to one or

I asked about this a few days ago, and I thought the general answer was
that if I get an object as the return  value of a function, it has already
been autoreleased and I don't have to release it myself.  However, the
following code (which is from an email I posted earlier today ...

I took this code verbatim out of the CFPreferences docs:
int dropMethod = 0;
CFStringRef dropMethodKey = CFSTR("dropMethod");
CFNumberRef dropMethodVal = CFPreferencesCopyAppValue(dropMethodKey,

For a program I'm writing, I want to show a 3-D model of an airplane
changing in roll, pitch, yaw, position, etc.
I assume that the way to do this is to grab a 3-D model of an aircraft
off the web, in a standard file format, use a simple OpenGL call to

How is it possible to read QT movies compressed with 10 bit and 16 bit
(PER CHANNEL) codecs?
The only code I have found to read QT movies uses 32-bit GWorlds. I
tried creating a 64-bit GWorld (on QT for Windows) and it failed.

Assuming I have a pointer to an NSPanel, say, can I obtain pointers to its
NSTextField objects?  I realize that one way to do this is make a class in
IB, create outlets for each textfield I'm interested in, and
control-click-drag to connect the class to the textfields.

I'm wondering if TCPA in Macs could affect the development of
freeware/shareware, or other developers with a low budget.
All of we have been hearing many apocalyptic rumours of how TCPA can
affect the future of users (and even more after the rumour that Apple

I have a panel with a bunch of text fields (names and scores in a high
scores list).  If the user gets a high score, I make its corresponding
player name textfield selectable, editable, bezeled, and finally call
selectText on it.  Seems to work.  These settings seem to be ...

After you get a CF object from CFDictionaryGetValue(), are you _NOT_
supposed to call CFRelease() on the item retrieved?
I had in my code:
cfStringRef = CFDictionaryGetValue(thePropertyListRef, CFSTR("test"));

I have a subclassed NSView that I paint black for a Tetris background.
Works fine.  However, I don't start the game at launch.  I wait for a New
Game menu command.  That triggers a game init that erases the NSView and
starts the game.  Works fine.

Where might I find an example of building a Mac OS X CGI with Xcode
that would work with Apache?  Thanks in advance.

I'm using XCode 2.1 and I want to have the project's info.plist file be
in  a subfolder of the project (the subfolder is called Resources).  So,
in other words, I have:
/Volumes/MacHD/MyProject/MyProject.xcodeproj

Hi folks. I am building a class that imports a filemaker database into a
  core data database. I managed to get a "hand-taylored" xml from
filemaker, in order to match the core data entity fields.
I am trying to use the NSXMLParser class; I considered using XML Tree

I know how to set an NSTextField value using any of the easily found set
functions in NSControl.  I can't find any methods for reading their
values.  Seems like an obvious command, but I don't see it in NSTextField,
NSControl, or NSResponder.  I think it might have something to ...
