i download vlc-android again, rebuild
and this error is gone

[svmodica]

Can you post your env setup for this?
I'm trying to do a build of vlc-android and I'm pointing to the 4.4.3 tools in the Android NDK.
I'm cross compiling on a mac.
I finally got bootstrap to make progress before hitting this:

I'm pretty sure I just have my env wrong. From what I can see, the android stuff doesn't want to be "arm-linux-androideabi". Maybe I'm mixing environments incorrectly?

I'm hoping someone has a "how to" that actually describes the setup in some more detail. I've been looking but I finally had to try rolling my own.

my os is ubuntu,ndk is android-ndk-r5b, android-sdk is 2.2
this is my build step:
1.cd ~/code
2.git clone git://git.videolan.org/vlc/vlc-android.git
3.cd vlc-android/extras/contrib/
4.export ANDROID_NDK=/usr/local/android-ndk-r5b
5../bootstrap -t arm-eabi -d android
6.make sure those tools is installed:
sudo apt-get install wget
sudo apt-get install autoconf
sudo apt-get install libtool
sudo apt-get install subversion
7.make
8.cd ~/code/vlc-android
9../bootstrap
10.mkdir builddir
11.cd builddir
12.../extras/package/android/configure.sh
13../compile -k
14.cd ~/code/vlc-android/extras/package/android
15.export ANDROID_SDK=/usr/local/android-sdk
16.VLC_BUILD_DIR=~/code/vlc-android/builddir VLC_CONTRIB=~/code/vlc-android/extras/contrib/build make

that is all

[svmodica]

Thanks! These steps got me going.
I'm building on mac os x 10.6.6.
I needed to load those same libraries and tools using ports. (they exist for mac)
Then I needed to do this before step 5:
export PATH="$PATH":"$ANDROID_NDK"/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin
Now it appears to be happy and building away!

[svmodica]

My extras/contrib build completed with no errors and I was able to execute step 12 (configure.sh), however the script wanted to look in linux-86 for my tool chain compiler rather than darwin-86. I had to manually edit that.

When config.sh completed, it showed this:

libvlc configuration
--------------------
version : 1.2.0-git
system : linux
architecture : arm
build flavour : debug
build vlc executable : no
plugins/bindings :

I think I'm OK, but I noticed that one of the PKG_CONFIG settings was:
PKG_CONFIG_LIBDIR="$VLC_SOURCEDIR/extras/contrib/hosts/arm-eabi/lib/pkgconfig" \
sh ../configure --host=arm-eabi-linux --build=x86_64-unknown-linux \

Not sure if that should be darwin or not.

[svmodica]

One last issue with building on my mac.
After completing step 13, I went on to set the SDK and VLC variables and did "make"
That failed like so:
/Volumes/SamsungOTG/vlc/vlc-android/builddir/modules/access/.libs/libaccess_attachment_plugin.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status

I'm sure this is because several libraries were missing earlier:

MAKE : media_library
MAKE : packetizer
ranlib: warning for library: .libs/libpacketizer_mpegvideo_plugin.a the table of contents is empty (no object file members in the library define global symbols)
ranlib: warning for library: .libs/libpacketizer_mpeg4video_plugin.a the table of contents is empty (no object file members in the library define global symbols)
ranlib: warning for library: .libs/libpacketizer_mpeg4audio_plugin.a the table of contents is empty (no object file members in the library define global symbols)

So I imagine I need to have the rest of the vlc stuff somewhere with these libraries built, yes? Maybe pull the entire tree into the ~/code directory and build that first?

Actually i don't know, i am sorry

[vlc120]

hi.
i think you should use ndk-Crystax (http://www.crystax.net/android/ndk-r4.php#download) instead ndk. i think it work. Can you post the detail steps to compile source code vlc by ndk?

[android.andjoy]

Dear Playing,

I met the same issue ans you posted on Fri Mar 18, 2011 6:30 am . but i am not lucky, the same error happens again and again even i rebuild the project. would you please tell me the building environment in details?

Thanks,

Best Regards,
D.Y

hey android.andjoy :
my os is ubuntu,ndk is android-ndk-r5b, android-sdk is 2.2
i download vlc-android again, rebuild
i have not chanage the building environment, is the same when i receive that error

HI Playing, My ubuntu is ubuntu 10.10 i386 32bit OS, not 64bit OS. i build again, but the following errors happen.

that is ok, just import use eclipse,and delete @Override in SurfaceCallback.java

[mochipoo]

svmodica,

I had the same error message while building in Mac.
I fixed it by changing following line in extra/package/android/configure.sh

From--> sh ../configure --host=arm-eabi-linux --build=x86_64-unknown-linux \
To--> sh ../configure --host=arm-eabi --build=i686-apple-darwin10 \

Hope that helps,
Grace

Any help is much appreciated!

Thanks

[mochipoo]

mtgeekman, Do you have subversion installed?

[mtgeekman]

it was a fresh install of ubuntu 11.04 with all updates applied.


following through the steps, in step 6 was too install some tools that would be needed one of them being subversion.

is there anything else that I would have needed to do besides installing it?


I am going to try on a different machine now. will edit this post with my results.

[edit]

ok after one more problem I managed to fix and then finish building vlc. was hoping it would work on my gtablet running cyanogenmod but no luck, force close when I try to open an avi file.

will give it a try on my droid 2 sometime tomorrow.

[mtgeekman]

Works great on my droid 2.

as for my Viewsonic G tablet, I am guessing that it doesn't work because it is running the nVidia Tegra 2 cpu instead of the standard arm processor...

From what I can see I need to change the target to something that is compatible with the Tegra 2 cpu.

Could someone post an .apk so that others can try VLC on Android as well?

so i am trying to build VLC-ANDROID on ubuntu 10.04 and i get to Build the JNI interface for libvlc but this is what i get:

i tried to delete my everything and start over but i got the same results. i am able to build the regular vlc with no issues i am unsure what i am doing wrong. i so want to see VLC on my samsung galaxy fascinate.
