我想在iOS中玩在线流使用vlc。 我找到了这个 http://www.videolan.org/vlc/download-ios.html 这样做，可以在模拟器中运行SimplePlayback源代码。 但是当为iOS设备构建它时，我得到同样的错误：
ld: warning: directory not found for option '-L"/Users/Data/Projects/B2/Document/VLCKit-2.2.0-rc1/Examples_iOS/SimplePlayback/../../build/Release-iphonesimulator"'
ld: warning: directory not found for option '-L"/Users/Data/Projects/B2/Document/VLCKit-2.2.0-rc1/Examples_iOS/SimplePlayback/../../build/Release-iphonesos"'
ld: warning: directory not found for option '-F/Users/ali/Downloads/build'
Undefined symbols for architecture armv7:
"_openat", referenced from:
_vlc_openat in MobileVLCKit(lt4-filesystem.o)
(maybe you meant: _vlc_openat)
"_fdopendir", referenced from:
_DirRead in MobileVLCKit(libfilesystem_plugin_la-directory.o)
_FileOpen in MobileVLCKit(libfilesystem_plugin_la-file.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
任何人都可以帮助我吗？ 感谢
