I think my question is pretty easy to answer. Well, I used to play with
some code on Linux and that was pretty easy. If I had to use a xyz lib
I used to download it in its tar.gz form, do the usual ./configure and
make + make install and the lib was there, usable. On OSX its not ...

Posted so anyone else Googling "sqlite hang" can find this.
We sometimes get persistent Sqlite database busy errors with
no apparent cause (all processes killed, etc) and no help from
the documentation. I found one cause:

In the process of porting an app from linux to osx.
(Thanks to Apple loaning some hardware)
On linux we are using shared libraries, some of which
are dependent on other shared libraries.

I have an application which (amongst other things) copies files to other
devices. Resource files should _not_ be copied (i.e. no ._myfile.ext).
Until now, I've been using cp from an NSTask to perform the copy (this
is instantiated from a separate thread). Obviously, as of 10.4 this ...

ive got a webpage i want to display in its own app (dont ask..). my
friend got it autoloading in there just fine but then lost it trying to

I'm trying to build a MusicKit/SndKit example-app called 'Spectro', and
XCode (v2.4, MacOSX 10.4.8, Intel) gives me this error: 'gcc-3.3:
installation problem, cannot exec `cc1obj': No such file or directory'
I searched all over (apple adc mailing lists notably) and the problem

I'm starting to get the xcode bus error yet again
i've zipped up all needed files and put them on my site for folks to download:

Would somebody please download this file (less than 600k and expands to about 4 megs)

How would you determine the CPU type/model information?
If you use things like preprocessor macros (__ppc__, __ppc64__,
etc.) it tells you what compiler options were used, not what's
really there.  If you compile generically on a G5 for example,

I've got an application (SeisMac) which uses a thread to animate
continuously. The animation continues while the window is being
dragged (good) but if you resize the window the animation continues
only while the window is actually changing shape (bad).

I am very new to Macs, and I'm trying to learn how to compile C and C++
programs in the terminal application.  I'm currently using OS X 10.4.8.
From everything I've read, gcc should be included with the system, but
I can't seem to find it.  I've tried using it on old programs from

I wrote a simple label programme for my own use. It prints a carton list
to a Xerox laser printer (network) on A4 paper and small sticky labels
from a Dymo 400 printer (local USB).
The problem is that if I print the A4 list first the labels printed on

Hi I am programming in Xcode 2.3 a C application running Max OS X
10.4.7.  I cannot determine why the program wont compile when I add
char *temp line in the program.  I keep getting "invalid operands in
binary +" error for that line.  The program works like it should when

I think I asked about something like this a few years ago, but I can't
find the thread, so...
I'm trying to draw a grid that has differing line widths - depending
on where in the grid the line is. (think sudoku)
