  • C++ IDE for OSX

    - by gprime
    When i was at university i wrote a lot of C++. I primarily used either Visual Studio (at the time it was version 6) or VIM (if i was on linux) as an editor to write my code. Since i have graduate and have been working primarily in web programming i have stopped writing C++. Since i graduated i have also bought myself and started using my Mac exclusively. I am now starting to get back to my C++ coding (just for fun) and would like an opinion on good IDE's for Mac. I am currently using xCode which seems kinda cool because it has everything built into it. Do any of you have any other IDE's that you would suggest that i give a shot or should i just stick to xCode?

  • "Refreshing" an XML feed on iPhone/Mac OSX

    - by Steve
    Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

  • GDB Not Skipping Functions without Debug Info

    - by Alan Lue
    I compiled GDB 7 on a Mac OS X Leopard system. When stepping through a C program, GDB fails to step through 'printf()' statements, which probably don't have associated debug information, and starts printing "Cannot find bounds of current function."

  • Ruby on Rails undefined method `camelize' for "app":String

    - by Lukasz
    Hi! I just tried to play with Ruby on Rails on Snow Leopard. I was following this tutorial: http://developer.apple.com/tools/rubyonrails.html Whatever I try to do with rails I end up with: MacBook-Pro-lm:~ lukasz$ rails blog **undefined method `camelize' for "app":String** MacBook-Pro-lm:~ lukasz$ rails --help **undefined method `camelize' for "app":String** Really basic things... however - verbosing rails works: MacBook-Pro-lm:bin lukasz$ rails -v Rails 2.3.5 MacBook-Pro-lm:~ lukasz$ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin10] MacBook-Pro-lm:bin lukasz$ gem -v 1.3.7 So it seems I have installed and upgarded ruby (using macports), rubygems and rails successfully (according to terminal). There are also few other packages installed to support we development like passenger and mysql5, etc... I can find ruby installed in the /opt/local/bin directory. My environment PATH variable is: PATH=/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin The is something fishy going on. It must be some stupid basic problem. Google says that there could be a problem with ruby-iconv library but I can not find/install this package using port or gem commands. Plese help.... what am I missing here?

  • Import error ft2font from matplotlib (python, macosx)

    - by Tomas K
    I was installing matplotlib to use basemap today when I had to install a lot of stuff to make it work. After installing matplotlib and be able to import it I installed basemap but I can't import basemap because of this error: from mpl_toolkits.basemap import Basemap Traceback (most recent call last): File "", line 1, in File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/mpl_toolkits/basemap/init.py", line 36, in from matplotlib.collections import LineCollection File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/collections.py", line 22, in import matplotlib.backend_bases as backend_bases File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/backend_bases.py", line 38, in import matplotlib.widgets as widgets File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/widgets.py", line 16, in from lines import Line2D File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/lines.py", line 23, in from matplotlib.font_manager import FontProperties File "/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/font_manager.py", line 52, in from matplotlib import ft2font ImportError: dlopen(/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so, 2): Symbol not found: _FT_Attach_File Referenced from: /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so Expected in: dynamic lookup So when I tried to import ft2font in python by: from matplotlib import ft2font I got this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so, 2): Symbol not found: _FT_Attach_File Referenced from: /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/matplotlib/ft2font.so Expected in: dynamic lookup Any idea what to do?

  • VPython in Eclipse - thinks it has the wrong architecture type.

    - by Duncan Tait
    Evening, So I've recently installed VPython on my MacBook (OS X, Snow Leopard) - and it works absolutely fine in IDLE and from the command line (interactive mode). However, eclipse has issues. Firstly it couldn't find it (which is a bit of an issue actually with all these 'easy install' python modules - when they don't tell you where they actually install to!) but I searched it out in the depths of Library\Frameworks... and added that to the System PYTHONPATH listbox in Eclipse. Now it can find it, but it says the following: Traceback (most recent call last): File "/Users/duncantait/dev/workspace/Network_Simulation/src/Basic/Net_Sim1.py", line 15, in <module> import visual File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/__init__.py", line 59, in <module> import cvisual ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so, 2): no suitable image found. Did find: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so: mach-o, but wrong architecture I am guessing that VPython might not be built for a 64-bit architecture (Intel), but the fact remains that it works in both IDLE and command prompt... So there must be a way to configure Eclipse to run it right? (Wishful thinking). Thanks for any help! Duncan

  • How to install PySide v0.3.1 on Mac OS X?

    - by ivo
    I'm trying to install PySide v0.3.1 in Mac OS X, for Qt development in python. As a pre-requisite, I have installed CMake and the Qt SDK. I have gone through the documentation and come up with the following installation script: export PYSIDE_BASE_DIR="<my_dir>" export APIEXTRACTOR_DIR="$PYSIDE_BASE_DIR/apiextractor-0.5.1" export GENERATORRUNNER_DIR="$PYSIDE_BASE_DIR/generatorrunner-0.4.2" export SHIBOKEN_DIR="$PYSIDE_BASE_DIR/shiboken-0.3.1" export PYSIDE_DIR="$PYSIDE_BASE_DIR/pyside-qt4.6+0.3.1" export PYSIDE_TOOLS_DIR="$PYSIDE_BASE_DIR/pyside-tools-0.1.3" pushd . cd $APIEXTRACTOR_DIR cmake . cd $GENERATORRUNNER_DIR cmake -DApiExtractor_DIR=$APIEXTRACTOR_DIR . cd $SHIBOKEN_DIR cmake -DApiExtractor_DIR=$APIEXTRACTOR_DIR -DGeneratorRunner_DIR=$GENERATORRUNNER_DIR . cd $PYSIDE_DIR cmake -DShiboken_DIR=$SHIBOKEN_DIR/libshiboken -DGENERATOR=$GENERATORRUNNER_DIR . cd $PYSIDE_TOOLS_DIR cmake . popd Now, I don't know if this installation script is ok, but apparently everything works fine. Each component (apiextractor, generatorrunner, shiboken, pyside-qt and pyside-tools) gets compiled into its own directory. The problem is that I don't quite understand how PySide gets into the system's python environment. In fact, when I start a python shell, I cannot import PySide: >>> import PySide Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named PySide Note: I am aware of the Installing PySide - OSX question, but that question is not relevant anymore, because it is about a specific a dependency on the Boost libraries, but with version 0.3.0 PySide moved from a Boost based source code to a CPython one.

  • MySQL-python 1.2.3 and OS X 10.5: 64- or 32-bit?

    - by Dave Everitt
    I've been happily using Django and MySQL in development on an existing machine running OS X 10.4 Tiger, and have set up a similar environment in 10.5 Leopard on a new 64-bit MacBook, with a working MySQL and Python 2.6.4. However, now I want them to communicate, easy_install MySQL-python gave ld warnings that the file is not of the required architecture, which led me to test my Python 2.4.6 install (from the Mac OS X disc image): >>> import sys >>> sys.maxint 2147483647 Ah. So my Python install appears to be 32-bit and (I think?) won't install MySQL-python for my 64-bit MySQL. There are lots of hacks out there for MySQL-python on OS X (mostly 1.2.2), but - after hours of reading - I'm pretty sure they won't fix this architecture mismatch. So I'm stuck because I can't decide whether to: give up, remove the 64-bit MySQL install (thorough methods, please?) and use the 32-bit MySQL disc image instead; re-install Python in 64-bit mode from the tarball, --with-universal archs-64-bit and --enable-universalsdk= as detailed in Python.org's 2.6 news. So my questions for anyone who has encountered this issue are: Is installing 64-bit Python on OS X 10.5 worth bothering with? If so, (naive, lazy question!) how are the two required arguments combined? If I just skip along in 32-bit (as on my working setup) what am I missing? I'm after a hassle-free install that's easy to reproduce on other machines (possible student use) so I'd really welcome your opinions, please!

  • Cocoa/Objective-C - Child window with text input without main window becoming inactive

    - by Josh
    Hello All, I have a need to spawn a window that will hover just above my main window in a cocoa application. I want this main window to allow the user to enter some text in an input box. All is well until the text input box actually gains focus. The main window becomes "deactivated." This window is borderless and is a slightly custom shape -- its more like a hover card than anything else, I suppose. Basically, I'd like this thing to work almost exactly like Spotlight (Apple + Space) -- you can enter text, but this is such an an ancillary operation that in the context of the greater UX, you don't want the jarring effect of the main window graying out (becoming inactive). You'll notice when you have some application open and in-focus, spotlight will not cause the window of that application to become inactive. This problem arises because text input seems to REQUIRE that the child window become the key window (it will not let you place the cursor in the text input field). When it becomes key, the main window becomes inactive. So far I've tried: Subclassing NSWindow for my main application and overriding isKeyWindow such that it only loses key when the application is no longer the users focus (as opposed to the window). This had the unintended effect of colliding with key status of the child window and having very strange effects on the keyboard input (some keys are not captured, like delete) Creating a view instead of a window. Doesn't work because of this problem -- you cannot draw over a Webkit WebView these days. Anybody Cocoa/OSX wizards have any ideas? I've become a little obsessed with this one. An itch I can't scratch.

  • Making RDoc Ruby Gem Default on Mac OS X

    - by jkale
    Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns: RDoc V1.0.1 - 20041108 I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here. Cheers! Update: Running "gem list -d --version 1.0.1 rdoc" returns: *** LOCAL GEMS *** rdoc (2.4.3) Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss Rubyforge: http://rubyforge.org/projects/rdoc Homepage: http://rdoc.rubyforge.org Installed at: /usr/local/lib/ruby/gems/1.8 RDoc is an application that produces documentation for one or more Ruby source files Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version. Update 2: I found out, using: `bash --debugger rdoc` that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH `export PATH=/usr/local/lib/ruby/gems/1.8/gems/` I now have a fresh working copy of the latest RDoc!

  • Programmatically controlled virtual drive

    - by Robert Lin
    How would I go about creating a virtual drive with which I can programmatically and dynamically change the contents? For instance, program A starts running and creates a virtual drive. When program B looks in the drive, it sees an error log and starts reading/processing it. In the middle of all this program A gets a signal from somewhere and decides to add to the log. I want program B to be unaware of the change and just keep on going. Program B should continue reading as if nothing happened. Program A would just report a rediculously large file size for the log and then fill it in as appropriate. Program A would fill the log with tags if program B tries to read past the last entry. I know this is a weird request but there's really no other way to do this... I basically can't rewrite program B so I need to fool it. How do I do this in windows? How about OSX?

  • Macports and virtualenv site-packages Fallback

    - by Streeter
    I've installed django and python as this link suggested with macports. However, I'd like to use virtualenv to install more packages. My understanding is that if I do not pass in the --no-site-packages to virtualenv, I should get the currently installed packages in addition to whatever packages I install into the virtual environment. Is this correct? As an example, I've installed django through macports and then create a virtual environment, but I cannot import django from within that virtual environment: [streeter@mordecai]:~$ mkvirtualenv django-test New python executable in django-test/bin/python Installing setuptools............done. ... (django-test)[streeter@mordecai]:~$ pip install django-debug-toolbar Downloading/unpacking django-debug-toolbar Downloading django-debug-toolbar-0.8.4.tar.gz (80Kb): 80Kb downloaded Running setup.py egg_info for package django-debug-toolbar Installing collected packages: django-debug-toolbar Running setup.py install for django-debug-toolbar Successfully installed django-debug-toolbar Cleaning up...

  • Python on Mac: Fink? MacPorts? Builtin? Homebrew? Binary installer?

    - by BastiBechtold
    For the last few days, I have been trying to use Python for some audio development. The thing is, Mac OSX does not handle uninstalling stuff well. Actually, there is no way to uninstall anything. Once it is on your system, you better pray that it didn't do any funny stuff. Hence, I don't really want to rely on installer packages for Python. So I turn to Homebrew and install Python using Homebrew. Works fabulously. Using pip, Numpy, SciPy, Matplotlib were no (big) problem, either. Now I want to play audio. There is a host of different packages out there, but pip does not seem willing to install any. But, there is a binary distribution for PyGame, which I guess should work with the built-in Python. Hence my question: What would you do? Would you just install the binary distributions and hope that they interoperate well and never need uninstalling? Would you hack your way through whichever package control management system you prefer and deal with its problems? Something else?

  • Has anyone setup tomcat to run virtual hosts using mod_jk

    - by Adam
    I work in OSX primarily with mostly PHP. Normally I work locally using MAMP and virtual hosts setup in my httpd.conf so that I can point a browser to http://some-project and have as many projects as I need setup. We have a project coming up where we need to serve JSP pages and I would like to set up my local apache server to serve only JSP files to Tomcat and everything else to MAMP using the same virtual hosts setup in: ~/applications/MAMP/conf/apache/httpd.conf So far I have: Successfully installed Tomcat Placed mod_jd.so in ~/applications/MAMP/Library/modules/mod_jk.so Added the module by placing: LoadModule jk_module modules/mod_jk.so in ~/applications/MAMP/conf/apache/httpd.conf Created /Library/Tomcat/Home/conf/jk/workers.properties and added the following lines: workers.tomcat_home=/Library/Tomcat workers.java_home=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home ps=/ worker.list=ajp12, ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp12.type=ajp13 worker.ajp13.mount=/*.jsp added the following lines: JkWorkersFile /Library/Tomcat/Home/conf/workers.properties JkLogFile /Library/Tomcat/Home/logs/mod_jk.log JkLogLevel debug to ~/applications/MAMP/conf/apache/httpd.conf I cannot start my MAMP however when these last two lines are present in my httpd.conf. Does anyone work like this? Any tips? Any clear ideas of what I'm doing wrong?

  • Cleaning up when exiting an OpenGL app

    - by Daniel
    This might be a dumb question but I've spent some time asking Google and haven't been able to find anything. I have an an OSX OpenGL app I'm trying to modify. When I create the app a whole bunch of initialisation functions are called -- including methods where I can specify my own mouse and keyboard handlers etc. For example: glutInit(&argc, argv); glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA); glutInitWindowPosition(100, 100); glutInitWindowSize(700, 700); glutCreateWindow("Map Abstraction"); glutReshapeFunc(resizeWindow); glutDisplayFunc(renderScene); glutIdleFunc(renderScene); glutMouseFunc(mousePressedButton); glutMotionFunc(mouseMovedButton); glutKeyboardFunc(keyPressed); At some point I pass control to glutMainLoop and my application runs. In the process of running I create a whole bunch of objects. I'd like to clean these up. Is there any way I can tell GLUT to call a cleanup method before it quits?

  • Git is not using the first editor in my $PATH

    - by GuillaumeA
    I am using OS X 10.8, and I used brew to install a more recent version of emacs than the one shipped with OS X. The newer emacs binary is installed in /usr/local/bin (24.2.1), and the old "shipped-with-osx" one in /usr/bin (22.1.1). I updated my $PATH env variable by prepending /usr/local/bin to it. It works fine in my shell (ie. typing emacs runs the 24.2.1 version), but when git opens the editor, the emacs version is 22.1.1. Isn't git supposed to use $PATH to find the editor I want to use ? Additional informations: $ type -a emacs emacs is /usr/local/bin/emacs emacs is /usr/bin/emacs emacs is /usr/local/bin/emacs $ env PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin SHELL=/bin/zsh PAGER=most EDITOR=emacs -nw _=/usr/bin/env Please note that I'd prefer not to set the absolute path of my editor directly in my git conf, as I use this conf across multiple systems. EDIT: Here's an bit of my .zshrc: # Mac OS X if [ `uname` = "Darwin" ]; then # Brew binaries PATH="/usr/local/bin":"/usr/local/sbin":$PATH else # Everyone else (Linux) # snip fi So, yes, I could add a line export EDITOR='/usr/local/bin emacs -nw' in the first if, but I'd like to understand why git is not using my PATH variable :)

  • g++ fails mysteriously only if a .h is in a certain directory

    - by ggambett
    I'm experiencing an extremely weird problem in a fresh OSX 10.4.11 + Xcode 2.5 installation. I've reduced it to a minimal test case. Here's test.cpp: #include "macros.h" int main (void) { return 1; } And here's macros.h: #ifndef __JUST_TESTING__ #define __JUST_TESTING__ template<typename T> void swap (T& pT1, T& pT2) { T pTmp = pT1; pT1 = pT2; pT2 = pTmp; } #endif //__JUST_TESTING__ This compiles and works just fine if both files are in the same directory. HOWEVER, if I put macros.h in /usr/include/gfc2 (it's part of a custom library I use) and change the #include in test.cpp, compilation fails with this error : /usr/include/gfc2/macros.h:4: error: template with C linkage I researched that error and most of the comments point to a "dangling extern C", which doesn't seem to be the case at all. I'm at a complete loss here. Is g++ for some reason assuming everything in /usr/include/gfc2 is C even though it's included from a .cpp file that doesn't say extern "C" anywhere? Any ideas? EDIT : It does compile if I use the full path in the #include, ie #include "/usr/include/gfc2/macros.h" EDIT2 : It's not including the wrong header. I've verified this using cpp, g++ -E, and renaming macros.h to foobarmacros.h

    I have the following code: jQuery(function ($) { var OSX = { container: null, init: function () { $("input.apply, a.apply").click(function (e) { e.preventDefault(); $("#osx-modal-content").modal({ overlayId: 'osx-overlay', containerId: 'osx-container', closeHTML: null, minHeight: 80, opacity: 65, position: ['0',], overlayClose: true, onOpen: OSX.open, onClose: OSX.close }); }); }, open: function (d) { var self = this; self.container = d.container[0]; d.overlay.fadeIn('fast', function () { $("#osx-modal-content", self.container).show(); var title = $("#osx-modal-title", self.container); title.show(); d.container.slideDown('fast', function () { setTimeout(function () { var h = $("#osx-modal-data", self.container).height() + title.height() + 20; // padding d.container.animate( {height: h}, 200, function () { $("div.close", self.container).show(); $("#osx-modal-data", self.container).show(); } ); }, 300); }); }) }, close: function (d) { var self = this; // this = SimpleModal object d.container.animate( {top:"-" + (d.container.height() + 20)}, 500, function () { self.close(); // or $.modal.close(); } ); } }; OSX.init(); }); To load this script, a button with the class "apply" has to be clicked... Does anyone know a way of loading this script "onload" without a button being clicked? I have tried a lot of things, but I am a newbie when it comes to Javascript. Thanks!
