If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
libav-user@libav.org mailing list or IRC #libav on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

Fixed this issue by removing "-g" flag in vlc/extras/package/ios/build.sh at line:
ARCH="armv7 -g"

Thanks gpinigin.

Other errors to fix:
1)add "LIBTOOL=@LIBTOOL@ --tag=CC" on the head of this file:
MobileVLC/ImportedSources/vlc/modules/video_filter/Modules.am.


2) CopyStringsFile
Summary: Building MobileVLC fails with the error,

The following build commands failed:
CopyStringsFile build/Release-iphoneos/VLC.app/pl.lproj/Localizable.strings Resources/pl.lproj/Localizable.strings
Details: The offending file, MobileVLC/Resources/pl.lproj/Localizable.strings is a UTF-16-LE file missing a byte-order-mark (BOM), which confuses Xcode for some reason.

Workaround: cd into MobileVLC/Resources/pl.lproj/ and execute

mv -n Localizable.strings Localizable.strings.backup && python -c "import sys; sys.stdout.write(chr(0xFF)+chr(0xFE))" > Localizable.strings && cat Localizable.strings.backup >> Localizable.strings

3)Update buildMobileVLC.sh, change the SDK version

SDK=iphoneos6.0

Now it succeeds in building.

Does anyone update the source in git://git.videolan.org/vlc-ports/ios.git?

It is about half year old.

Why I get this warning when running?

'IMG_4148' is unsafe and will crash, ignoring.

When playing, it crashed:

Seems, that avcodec plugin isn't loaded.

Furthermore, I'd recommend you to disable --avcodec-fast option in [VLCLibrary init], as it produces crashes.

P.S. I'm preparing several patches, will post them for review soon.

"plug-ins loaded: 1 modules". your static libvlc is clearly corrupted, since it should find more than 100 modules by default.

How to fix "plug-ins loaded: 1 modules" problem?

Take look at vlc-plugins.h in ImportedSources/VLCKit/MobileVLCKit. This file is generated automatically by AggregateStaticPlugins.sh, so if in this file only 1 plugin added then problem in AggregateStaticPlugins.sh, otherwise take a look at compilation process of vlc(i.e. AggregateStaticPlugins.sh found only one properly compiled plugin).

I have solved the problem - "vlc: unknown option or missing mandatory argument `--avcodec-fast'" . This is just because of my lazy..... We need to build both of os and simulator once to complete the compile process. After I type ./buildMobileVLC.sh -s , the problem do not appear, so no crash in VLCLibrary.m - init now.

I also got this error "GNU assembler not found, install gas-preprocessor".
The reason was that during the tools building step, CMake build failed and this was generating other errors afterwards.
