Hi All,

I'm trying to compile VLCKit for tvOS but I'm always getting the following error

[info] all done
[info] Building static MobileVLCKit.framework
[info] Building MobileVLCKit (MobileVLCKit, Release, iphoneos)
xcodebuild: error: SDK "iphoneos9.0" cannot be located.

I'm using this command to build

Code: Select all

./buildMobileVLCKit.sh -f -t

any idea?

Thanks,

Matteo

Hi,

I had the same problem, the only way to make a static library is to open MobileVLCKit.xcodeproj, switch to TVVLCKit and build. You get libTVVLCKit.a and headers.

Ok, compiled with Xcode, added both .a file and headers to my project now I get this

that looks to me impossible

Thanks,

Copy *.a file and headers into your project. Replace all you import to:

#import "TVVLCKit.h"

when you start typing so you receive autocomplete.

I think I've done but probably it's my fault

I'm trying with this example https://mega.nz/#!ahMW0bwA!USoUVlehDrXU ... UjfZ8Lc0fk

Posted: **27 Sep 2015 15:59**

if I play little bit with h file I'm able to compile but i get liking errors... probably my .a file is completaly wrong...is there any guid to compile for tvOS from scratch?

Instructions on wiki are not so clear...(at least for me)

You don't link against libc++.

Posted: **28 Sep 2015 19:00**

oh...i'm so stupid..thanks!

Posted: **21 Oct 2015 17:49**

hi matron any chance you can post a sample project with this fixed? I have the same issue but there seems to be a bug in Xcode 7 beta which isn't letting me link against libc++

Posted: **21 Oct 2015 20:13**

Hi, I only added the following libc++.tbd lib to xcode

Posted: **21 Oct 2015 20:50**

Afraid I amn't having much luck..

Posted: **22 Oct 2015 06:58**

Remove that and import every single VLC*.h file

I'm trying to add a VLC player to my TVOS app and for this I'm trying to create a static library of TVVLCKit. This thread is the closest I've found to documentation on how to do this so I really hope that someone here can guide me. This is what I've done so far:

1. Downloaded https://code.videolan.org/videolan/VLCK ... rchive.zip
2. ./buildMobileVLCKit.sh -f -t
3. Got the error "xcodebuild: error: SDK "iphoneos9.0" cannot be located."
4. Opened MobileVLCKit.xcodeproj in Xcode, switched to TVVLCKit and built successfully.

Now, I'm supposed to find and copy the libTVVLCKit.a and header files to my project. The problem is that I can not for my life find any file called libTVVLCKit.a. Would really appretiate if someone code clarify the steps needed to create a static library from scratch or pinpoint what I'm doing here. Thanks!

Posted: **25 Oct 2015 07:45**

I did the following
1. downloaded zip file
2.

Code: Select all

./buildMobileVLCKit.sh -t

3.

Code: Select all

./buildMobileVLCKit.sh -t -s

4. Opened MobileVLCKit.xcodeproj in Xcode, switched to TVVLCKit and built successfully for device.
5. built successfully for device simulator
6. Open terminal, go to the folder where Xcode produced libTVVLCKit.a file (for me /Users/xxxxx/Library/Developer/Xcode/DerivedData/MobileVLCKit-cajvscpvucjubqcjljaxxzklzcas/Build/Products/)
7. Run the following to have a static lib for tv and simu

Code: Select all

lipo -create Debug-appletvos/libTVVLCKit.a Debug-appletvsimulator/libTVVLCKit.a -o libTVVLCKit.a

8. Add the new libTVVLCKit.a to your project

matrog: thanks for the steps, you're a saver !! I've now managed to include the .a and header files into my project.

Do you have a good example of a Player-videocontroller for TVOS? I'm using an old one made for IOS but needed to remove a lot of stuff that is not available on TVOS (UIActionSheets, UISliders etc). Maybe also due to this I'm getting errors when I try to build my project (for the simulator):

Also getting a lot of:

ld: warning: URGENT: building for tvOS simulator, but linking in object file

This might be problems in the future I guess. Any tips appretiated!

Posted: **25 Oct 2015 16:35**

For iconv include iconv lib, for the player i started from the examples included in the vlckit

Posted: **25 Oct 2015 23:26**

Thanks once again, it's now building wihout errors. As for the viewcontroller I'll start with the IOS version and work my way through to a more TV-like experience.

Posted: **02 Nov 2015 12:42**

Hi @matrog thanks a lot for your support.
I'm trying to follow your guide but during the building process I got this error:

"library not found for -lTVVLCKit"

I'm not sure about this step:

"8. Add the new libTVVLCKit.a to your project"

Only drag in to my project?
Any idea to solve the problem?

Thanks in advance.

Sorry to hijack this thread again..
@magrot: VLC is working fine in both the simulator and on the device itself. However, when I try to archive I get the following error:

Code: Select all

ld: bitcode bundle could not be generated because '/Users/tobias/Dropbox/Dev/fireflixtv/fireflixtv/libTVVLCKit.a(VLCMedia.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build for architecture arm64

I understand that vlc must be built with bitcode support for TVOS. Question is where I do that? In the build script or in xcode somewhere?

Now, let's see if I an give something back to the community

@ilvolodel: copy the libTVVLCKit.a to your project folder. In Xcode, go to your Target->Build Phases->Link Binary With libraries. Press the + sign and then "Add other" and browse to the libTVVLCKit.a

Posted: **03 Nov 2015 11:02**

Bitcode is build setting of MobileKit project...switch to tvkit and enable it

Posted: **03 Nov 2015 11:43**

The problem is that there is no bitcode options when selecting TVVLCKit:

When checking the other targets they already have bitcode enabled.

Posted: **03 Nov 2015 14:54**

that's strange...there is only for MobileVLCKit.

Unfortunately i cannot try since I no longer can compile due to other issues..there's another thread about that.

Once I can compile again I'll let you know.

I did the following

Hey guys,

I followed this thread really carefully but everything I tried failed. Can't seem to create the static Library. Step 1& 2 are fine but Step 3 throws an error for me. Anyone else having this issue? Is there any place to get a precompiled version of this? Compiled over 20 times now, tried different version and still nothing.
I would really appreciate the help.

Thanks

point 3 is raising an error for everyone I guess, please see this

https://forum.videolan.org/viewtopic.php?f=36&t=129127

I can share my libTVVLCKit.a (and .h files) to see if works, but it's not the latest version.

Posted: **04 Nov 2015 09:32**

@matrog: if it's with bitcode enabled then please share
