[iPhone] OpenAL Linking errors

Hi,
I try to compile CrashLanding sample from SDK, but i have 18 errors:
"_alcCreateContext", referenced from:
"_alSourceStop", referenced from:
"_alSourceQueueBuffers", referenced from:
"_alGetError", referenced from:
ld: symbol(s) not found
collect2: ld returned 1 exit status
and similar related to OpenAL.
it's have already added openAL framework,AudioToolbox, CoreAudio.
how to solve this ?

Interesting, when I looked at the time in Time Zone Support it had been reset to GMT - 4, which put me in the Atlantic Time Zone, rather than Eastern Time Zone. It likely reset itself when I was travelling, as I never had a problem with Time Syncing before. At any rate, that solved the problem, and i thank you.

  • IPhone SDK - Linking error with CLLocationManager

    Hello.
    I have a linking error when I try to use thr CLLocationManager in my iPhone application by using the example of source code given in the Developer Center.
    I have the following error : ".objcclass_nameCLLocationManager", referenced from literal-pointer@_OBJC@__clsrefs@CLLocationManager in localisation.o
    symbol(s) not found.
    Do you have an idea ?
    Thank you for your answer.
    Patrick Schevenels.

    Just for clarification, there's a flood of developers now purchasing Macs to code for the iPhone platform. For those of you new to Xcode, you add a framework by doing the following:
    1. Open your iPhone project in XCode
    2. In the project window, ctrl+click (or right-click if you have 2-button mouse) on 'Frameworks' folder > Add > Existing Frameworks
    3. Navigate to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Li brary/Frameworks/CoreLocation.framework
    4. Click 'Add' button
    5. Compile
    Also, for anyone coming for the ActionScript Java or C# world, I've been blogging on transitioning to iPhone OS development platform.

  • IPhone -- OpenAL Linking

    I'm building an OpenAL program, and have run into an annoying problem. I have -framework OpenAL set as a linker flag, and I have added the OpenAL.Framework to the XCode project. Everything compiles okay, but when I go to run a simple test program:
    #include <OpenAL/al.h>
    #include <OpenAL/alc.h>
    void initializeTest(void) {
    ALCdevice *pDevice = alcOpenDevice(NULL);
    It will return _alcOpenDevice as an undefined symbol when it tries to run the linker (ld). Any suggestions would be most helpful (obviously this is a very simple test case which keeps the major project from working).

    There is no sample OpenAL code in any of the iPhone SDK docs.
    I tried OpenAL against the initial iPhone Betas and had poor results, but I have not tried it against the shipped iPhone SDK.
    For good OpenAL sample code, check out the ALUT framework which I believe is coupled with the OpenAL SDK:

  • Where is my 'open link in new tab' option when right-clinking a link? and... why does every page load twice? and... why do i get 'internet explorer cant open link' errors when using firefox? and... why doesnt the red 'x' stop load icon work anymore? i jus

    i have all the issues stated in my question as of this morning. they werent there last night. WTF happened to my beloved firefox? BTW,
    I got an amd dual core 4000, nvidia gtx 9800, 4 gigs ram, running on windows xp sp3.
    BTW, windows updated last night, and thats when i got the problems
    == User Agent ==
    Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; WWTClient2; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; Creative AutoUpdate v1.40.01)

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • IPad Air open links in apps

    How to make the iPad open a link (from a website, from an email, from another app, from anywhere) in the correct app?
    i.e. open in Etsy, Pinterest, Instagram...

    Well, the way that I read it, it does answer the question, the OP talks about this occurring in apps as well.
    "Is there a way to make the iphone open links in their appropriate app instead of in the web browser. It drives me INSANE! I click on a groupon link in my email and I am sent to safari where I get a pop up that says "download the groupon app."  Same thing happens for many apps I use everyday.  The Iphone isn't smart enough to open the links in the appropriate app?"
    The feature has to be built into the app itself. At least that is what I get out of it, if I read the entire discussion all the way through. But I could be misinterpreting what is being stated.
    Sorry, I do no social networking at all, so I can't speak about that. Actually, I do use LinkedIn in a very limited fashion and when I accept an invitation from my email, It does tell me to get the app, but I can close that window and then LinkedIn opens in Safari and I don't need the app.
    That probably doesn't answer your question, but I did want to give it a try.

  • IPhone Safari doesn't open links in new page

    Under iPhone Safari Settings, I've got it set to Open Links In New Page, but when I click on links in Safari, that doesn't happen. When I set it to Open Links In Background, that doesn't happen either. Links open in the same page no matter what the setting.
    Anyone know how this can be fixed? Thanks.
    (iPhone 4S running IO5)

    It depends on the website. Some websites have it set up to take you to a new tab, some do it in the same tab.

    Hi,
    Have you tried the hyperlinks in other Office programs like Outlook and PowerPoint? Do they work well?
    You may need to run the Fix it in this kb below:
    http://support.microsoft.com/kb/310049/en-us
    You can also try the steps in the section "Let me fix it myself". Although this kb is written for Outlook, it may help in your scenario as well.

  • Link error: Failed to open external module

    Newbie question #2... I'm in chapter 5 of the tutorial, just added the button to calculate min and max values of the sinewave. I get two link errors when I try to run the program.
    2 Project link errors:
     Failed to open external module
     Failed to open external module
    If I comment out the MaxMin1D function and fudge the min and max values the program runs.
    Any ideas?
    The function I added is as follows which appears  to be identical to the sample in the tutorial.
    int CVICALLBACK FindMaxMin (int panel, int control, int event,
            void *callbackData, int eventData1, int eventData2)
        ssize_t min_index;
        double min;
        ssize_t max_index;
        double max;
    //    max = 5;
    //    min = 3;
        switch (event)
            case EVENT_COMMIT:
                MaxMin1D(sine, 100, &max, &max_index, &min, &min_index);
                SetCtrlVal(panelHandle, PANEL_MAX, max);
                SetCtrlVal(panelHandle, PANEL_MIN, min);            
                break;
            case EVENT_RIGHT_CLICK:
                break;
        return 0;

    I searched for analysis.h, found it and copied it to the same folder as sample1.c and the program now links and runs.
    I'm wondering if I'm missing something in the configuration (not smart enough to know where to search)???
    Thanks

  • Linker error: can't open "ini.lib"

    Hi,
    I've just installed the Evaluation copy of the Measurement Studio Tools for Visual C++ and whenever I try to run an example or a program that I create I get a linker error referencing ini.lib? I can find ini.lib in 2 folders both descending from VXIpnp, but I've also called the hotline and I was told I need the INI driver. Doesn't that come with the evaluation CD or do I need to manually download it from your website and then install it myself?
    Alex

    You need to add the path of the ini.lib to the VC++ environment. The installer should have done this for you, but it must not have. Go to Tools->Options and under the directories tab, add a Library files entry that points to the ini.lib directory.

  • The broken link error

    Hi,
    Please help me with this broken link error in Office Excel 2010. Thank you.
    The problem is: a broken link cannot be removed from the file. The link was used in data validation, which refers to a list of values. After the path was corrected, it still shows there’s a broken link. Here are the details:
    I have 4 files named “000TVA_Test – 3”, “000TVA_Test – 4”, “000TVA_Test – 5”, and “000TVA_Test – 6”. The posterior files were developed based on the previous files.
    In Test-3, sheet “Template “, cell “L4”, “O4”, “R4”… were built as dropdown list using data validation. The list source is in the “Library” worksheet. There’s no problem so far.
    Test-4 was firstly copied from Test-3. In this file I renamed the worksheet from “Library” to “Setting” and the link was broken from here. I can also fix the broken link in this file. (While I didn’t realize there was a broken link.)
    In Test-5 I fixed the path, but every time when opening the file, the broken link still shows.
    In Test-6 I’ve removed the data validations. The broken link is still there.
    I tried to find solutions online. I tried common methods, cannot find anything in the files is still using links. I also tried the “findlink.xla” add-in, but it only worked for Test-4, and couldn’t find the link in other files.
    Please help. Thank you!
    I uploaded files here: https://onedrive.live.com/redir?resid=1A97736E0ABBAA41!113&authkey=!AF5wAd9rwUPnYyE&ithint=folder%2cxlsm
    Thanks again!

    Hi,
    Based on my tested the files downloaded, I found that Test-5 & Test-6 included the "A defined name that refers to an external workbook", Test-4 had not. (Please click Formula Tab>Name Manage, you'll see them.)
    However, the Break Links command cannot break the following types of links:   
    A defined name that refers to an external workbook
    A ListBox control with an input range that refers to an external workbook.
    A DropDown control with an input range that refers to an external workbook.
    http://support2.microsoft.com/kb/291984/en-us (It also applies to Excel 2010)
    Thus, we'd better try the workaround: re-build the Test-5 & Test 6.

  • Itunes opens with error -50

    Itunes opens with error -50 on my Mac. Once open signing in causes error 5002. Signing in from App store just fails. My Mac pc does not appear to be registered anymore and I can't sign in. On screen Support buttons don't connect so can't contact support online. Tried all the work arounds in discussions but no joy. Even tried deleting itunes to start agin but you can do that apparently. For one work around I Signed in through Safari to change payment details but payment option was not displayed. Getting really p'd off.  All is ok on my iphone/ipad etc but not my main pc. Any printable suggestions appreciated.

    Found a fix that worked, didnt even need to refresh the network settings
    Click the Finder icon in the Dock.
    Choose Go to Folder from the Go menu.
    Type:  /Library/Preferences/SystemConfiguration
    Click Go.
    In the Finder window, locate the file named "NetworkInterfaces.plist" and drag this file to the Trash.
    Restart your computer.
    Once your computer has restarted, you will not be able to connect to the Internet. You will need to refresh your network settings to be able to connect again:
    Choose System Preferences from the Apple () menu.
    Choose Network from the View menu.
    If you're using Mac OS X v10.4, choose New Location from the Locations menu.
    Click Apply Now at the bottom right.
    If your network connection requires any special settings, you will need to put them back in at this point. You would have received these from your ISP or network administrator.

  • Cannot open document (Error: INF)

    We have migrated reports from version Business Objects 6.5.1 to Business Objects XI 3.1 SP2. We have been receiving sporadic 'Cannot open document (Error: INF)' now and again whenever you open Desktop Intelligence reports using Infoview. Have any other users come across this issue using BOXI 3.1 SP2. I do not believe that this issue occurred on SP1.
    This error is very frustrating.
    I have browsed various forums and implemented changes which have had no effect whatsoever including the SAP Marketplace.
    We are also receiving SetPrompts Failed errors. When a report is opened in Infoview and you refresh a report, a blank dialog appears with a red cross. if you refresh the report again then the SetPrompts Failed error appears. I have evene made changes according to article 1364437 based on this error and this has not resolved the issue.
    Regards
    Dipendra

    We're on BOXI3.1 SP2 aswell and we have had the same sporadic issue - Cannot open document for Deski reports. This is causing some serious concern amongst our users over system stability.
    You can recreate the situation by shutting down the InputFileRepository server and you get the same message. I've noticed that when this happens there is a mesage in the fcproc log file 'm_repFileMgr.Download failed'
    My theory is that there may be some congestion in linking between the desktopintelligence server and the inputfilerepository. In addition, we had some logging on the fileserver and at the time of the error there was no mention of the report that failed or any error. We contacted SAP about this but did not get a satisfactory response. There were some heavily utilised DESKi reports which we managed to convert to Webi to take the load off and we also dropped the timeout to 20 minutes (not brilliant but it did mean that if we got the message the users wouldn't have to wait too long before it was resolved in case they couldn't get hold of IT).
    I also upped the parameter for Maximum Retries for File Access in case it was having problems getting the file.
    The result of this was that the error appeared to go away... until yesterday!!!
    Any further insights welcome.
