I have compiled the labstreaminglayer library for an iOS app, which works fine. But I would like to do some configuration as described here. But I can't get the library to find the lsl_api.cfg file.
Just putting it in any of the folders in XCode doesn't work, even though I can see that is there by searching for it and printing the path. I can set the LSLAPICFG environment variable but again anything I can think to put in there for a relative path doesn't point to the right place and I can't find any other env variable in this list which gives the absolute path...
With the benefit of a nights sleep I realised I can just edit liblsl and add some logging to figure out what is going on. So liblsl tries to look for the config file in the ~ folder, giving the path:
/private/var/mobile/Containers/Data/Application/GUID1/
While the lsl_api.cfg file is copied to:
/private/var/containers/Bundle/Application/GUID2/APPNAME.app/lsl_api.cfg
And libsl can't seem to access files in the GUID2 folder at all, something to do with sandboxing perhaps?
But both liblsl and the App can both access the /Documents folder (perhaps because I enabled iTunes File Sharing?) so I can just chuck the cfg file in there and update libsl to find it. With the added benefit that I can just edit it on my mac.
So I'm still not sure what I would do if I didn't want to put the cfg file in the /Documents folder but at least this works!

I am new for centos installation. I downloaded a minimul version of centos 6.5, around 339.7mb of size. I am trying to install this with GUI interface but I got an error after selecting the drive option, which comes after selecting the country.
This is complete message,
Unable to read package metadata. This may be due to missing repodata directory. Please ensure that your install tree has been correctly generated.
Failare:
repodata/743fec56b2af0ce8d6ec82c47a4efafc2a4d18cddfa9683f29611cb18d1a33de-primary.sqlite.bz2 from anaconda-CentOS-201311271240.i386: [Ermo 256] No more mirrors to try.
Sorry but I am new here, so I can't put the exact image here.
I believe that i had this same issue and was able to solve it.
The files under the /repodata folder are missing their file extensions and are not matching their full names in the "TRANS.TBL" file, under this same dir.
Rename all the files to match what is in the "TRANS.TBL" file, then try the install over again.
Please let everyone know if this works for you.
In the past i would just put a URL in that pointed to the correct files on a server, i feel that most people take this workaround and that's why it's not as hot of an item as it should be. I hope this gets fixed in the .ISO.
Thank you,

It worked for me.
I renamed all 8 files.
i.e. 0e371b19e547b9d7a7e8acc4b8c0c7c074509d33653cfaef9e8f4fd1d62d95de
0e371b19e547b9d7a7e8acc4b8c0c7c074509d33653cfaef9e8f4fd1d62d95de-primary.sqlite.bz2
The correct file name is given in file "repomd" under folder repodata
example - location href="repodata/b124f0ec5323cfee56b420906a3103f0daef656dde3f7ac8220120aa7504e57a-primary.xml.gz"
I had exactly the same issue ;
under "repodata" directory opened "repmod" xml file
Searched file name within repmond xml file
Found matching strings
Renamed 8 files as specified in .xml file
and it worked like a charm
Thanks to "Your Friend"
I had the same problem. Even if you manage to get past this step, you will encounter at a later point other errors related to filenames.
The root cause was using Unetbootin to create the bootable media. I switched to Rufus and everything works fine now.
I have tried to move the files in my project folder to a different folder and everything went ok, except that Xcode cannot find my Info.plist file now. This is the error I get.
could not read data from '/Users/jamiefraser/Developer/CocoaTouch Apps/MyApp/MyApp/MyApp/MyApp-Info.plist': The file “MyApp-Info.plist” couldn’t be opened because there is no such file.
The actual files location is
'/Users/jamiefraser/Developer/CocoaTouch Apps/MyApp/MyApp/MyApp-Info.plist'
I have checked the build settings for the project and they read
MyApp/MyApp-Info.plist
I have tried deleting the build folder and cleaning the project, but I always get this same error. I appreciate any help you can offer
Remove MyApp/ portion from build settings. plist file usually is located in the same folder ad project. You can always open project file in vi and edit it manually.
It is just a guess but it seems like one trailing /MyApp is too much in the location you are wanting to read from:
'/Users/jamiefraser/Developer/CocoaTouch Apps/MyApp/MyApp/MyApp/MyApp-Info.plist'
As opposed to the actual location:
'/Users/jamiefraser/Developer/CocoaTouch Apps/MyApp/MyApp/MyApp-Info.plist'
It would make sense to check out the URL / PATH variable you want to read from.
I had the same problem after trying to duplicate and rename a project.
In Build Settings, I had to fix two paths before I finally got it compiling successfully:
Under Packaging, Info.plist
Under Apple LLVM 5.0 - Language, Prefix.pch
I'm trying to get my ad hoc build distributed but have started experiencing problems. It used to work up until around a week ago, but now ITunes gives an 0x8008017 error when I try to Sync.
I've narrowed it down by using the iPhone Configuration Utility and then discovering the error seems to be coming from a failed code sign. I've ran codesign -vvvv myApp.app and the outup lists a load of missing resources from my Help documents (from my Apps Resource folder). each missing resource begins ._ so for my index page:
01 - Index.html
the codesign is also expecting: ._01 - Index.html
It also has the existing file listed (as it should) but fails because all ._files are not included in the app.
I've looked through my projects directory and can't find any files beginning with ._ so am not sure where the codesigner is getting these filenames from, but they are included every build, after a clean or an Xcode restart.
All the resources that are causing problems are all recently updated files that I copied over the old resources at the beginning of the week; might this be something to do with it?
Any help appreciated
Make sure you do one of these:
copy those files with an Xcode Copy Files phase, which should Do The Right Thing by default, or
exclude resource forks and ._* files if you copy through a script, or
make sure you build on HFS volumes (where ._* files are not generated for resource forks).
Sounds like your partition type is generating resource-fork files which are also being signed as separate files in the bundle, rather than as part of the original files (which is bad); and then, they're also not getting copied (if you use Finder zipping, they'll be removed and set aside in a different portion of the Zip file, IIRC), again bad. Avoid having them in the bundle, so they don't get signed and you don't have to wade through this mess :)
I always use one folder on my filesystem for an Xcode project. It contains all project files. When I zip it and send it to a friend, she can't just ipen the xcodeproj file. It opens, but all paths are broken and build fails because all the classes don't find the #include'd files. But when I download i.e. some example projects from apple, these work perfectly. What am I doing wrong?
UPDATE:
I'm doing it like this:
1) I create a project and specify an directory on my desktop
2) In that directory I create an "images" directory and add images to it
3) I pull this images directory out and drag it into the Resources Groups&Files. Xcode asks if I want to copy it to destination folder, I click no. Because it's already there. All other things are set to default.
4) all other things are just created within xcode, and xcode just puts all classes in the Classes directory of my project.
5) when I want to add images, I first put them in the directory of the project, and from there drag them into the Images group in xcode. That's to make sure xcode doesn't mess them up with everything else. Otherwise it would just copy them to the root of my project directory rather than inside the Images directory, which doesn't make sense. In fact, the whole Groups&Files filesystem doesn't make sense at all, it's one big mess. Apple's biggest mistake in Xcode so far. That's why I have to do such stupid things.
We don't really know exactly what you're doing so it's hard to see what you're doing wrong.
Perhaps inspect the xcode project files directly, see if you have hardcoded paths. That's a sure fire problem. Make sure you copy resources into the project instead of referencing them externally, etc.
I expect that you have "search path" build setting set to an absolute path on your machine, rather than a path relative to the project. Best way to tell is to post a portion of the build transcript from the failed build and look at the -I directives. If those paths don't exist on your friend's machine, then they should be changed from absolute paths to paths that start with ${SRCROOT}.
Are you just trying to build on the second machine or are you trying to deploy to a device on the second machine? If you are trying to deploy to a device (iPhone or iPod Touch) then it probably has something to do with Code Signing and Certificates.
so I am working on a jb app that requires writing to the file system (/var/mobile/Library/Downloads specifically), and I tried hard coding it in like someone recommended but I cant seem to make it work, i know how to do so to the Documents directory in my app but not the file system, any ideas? thank you!
edit 1 - as reference: the way that the Safari DL Plugin does it
try this path
/private/var/mobile/Library/Downloads
You need to check if the directory already exists or not before writing to it. You can use NSFileManager class for file/directory operations. You also need to check for the permissions on that folder, your app if not running as root cannot write to folders which only root has access to.
