Doxygen on Snow Leopard

September 06th, 2009 | Category: C, Doxygen

If installing doxygen from macports doesn’t work for you, you’ll have to build doxygen from source. Unfortunately you’ll get an error when building doxygen as well: “error This version of Mac OS X is unsupported”.

The fix is fairly straightforward:

-Download doxygen src
-Edit the file src/qglobal.h
-Find line 73 (we’re changing a chunk from this line)

Change this:

#if defined(__APPLE__) || defined(macintosh)
#define _OS_MAC_
#  ifdef MAC_OS_X_VERSION_MIN_REQUIRED
#    undef MAC_OS_X_VERSION_MIN_REQUIRED
#  endif
#  define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_3
#  include <AvailabilityMacros.h>
#  if !defined(MAC_OS_X_VERSION_10_3)
#     define MAC_OS_X_VERSION_10_3 MAC_OS_X_VERSION_10_2 + 1
#  endif
#  if !defined(MAC_OS_X_VERSION_10_4)
#       define MAC_OS_X_VERSION_10_4 MAC_OS_X_VERSION_10_3 + 1
#  endif
#  if !defined(MAC_OS_X_VERSION_10_5)
#       define MAC_OS_X_VERSION_10_5 MAC_OS_X_VERSION_10_4 + 1
#  endif
#  if (MAC_OS_X_VERSION_MAX_ALLOWED > MAC_OS_X_VERSION_10_5)
#    error "This version of Mac OS X is unsupported"
#  endif
#elif defined(MSDOS) || defined(_MSDOS) || defined(__MSDOS__)

To this:

#if defined(__APPLE__) || defined(macintosh)
#define _OS_MAC_
#  ifdef MAC_OS_X_VERSION_MIN_REQUIRED
#    undef MAC_OS_X_VERSION_MIN_REQUIRED
#  endif
#  define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_3
#  include <AvailabilityMacros.h>
#  if !defined(MAC_OS_X_VERSION_10_3)
#     define MAC_OS_X_VERSION_10_3 MAC_OS_X_VERSION_10_2 + 1
#  endif
#  if !defined(MAC_OS_X_VERSION_10_4)
#       define MAC_OS_X_VERSION_10_4 MAC_OS_X_VERSION_10_3 + 1
#  endif
#  if !defined(MAC_OS_X_VERSION_10_5)
#       define MAC_OS_X_VERSION_10_5 MAC_OS_X_VERSION_10_4 + 1
#  endif
#  if !defined(MAC_OS_X_VERSION_10_6)
#       define MAC_OS_X_VERSION_10_6 MAC_OS_X_VERSION_10_5 + 1
#  endif
#  if (MAC_OS_X_VERSION_MAX_ALLOWED > MAC_OS_X_VERSION_10_6)
#    error "This version of Mac OS X is unsupported"
#  endif
#elif defined(MSDOS) || defined(_MSDOS) || defined(__MSDOS__)

All we did was add in a definition for 10.6.

Now run the install:

./configure
make
sudo make install

Apple System Log Cocoa Wrapper

August 15th, 2009 | Category: Apple, C, Cocoa, Obj-c

Here’s a quick apple system log cocoa wrapper. Open the terminal, and type “man asl,” asl is the wrapper around syslog - which seems to be the first syslog for apple. The Console app (/Applications/Utilities/Console) shows all messages sent through asl.

Here’s a link to the files:

GDASLLog.h
GDASLLog.m
GDASLLogManager.h
GDASLLogManager.m

And here’s how you want to use it:

GDASLLog * log = [[GDASLLog alloc] initWithSender:@"MyAppName" facility:@"com.codeendeavor.MyAppName" connectsImmediately:TRUE];
 
//optionally set the file to write to. You'll still see logs in Console if you don't set this,
//but this way you can get the log file if needed.
[log setLogFile:@"/Library/Logs/MyApp"];
 
[log info:@"HELLO WORLD"];

And there’s a manager to hold references to your logs:

GDASLLogManager * gdLogMan = [GDASLLogManager sharedInstance];
[gdLogMan setLog:log forKey:@"logID"];
 
//GDASLLog * log = [gdLogMan getLogForKey:@"logID"];

I’ve been using this in an app to log some problems that were happening on another computer. I don’t leave these in when it’s ready to go. This just simplifies writing out some logs.

Enjoy.
