vlc-android building contribs problem

[bero7]

Hello,

I'm having problems building the contribs for vlc for android.
I followed the procedure
1. install sdk
2. unpack ndk
3. install eclipse and ADT
4. get source from git

..and the thing breaks at building contribs, specifically libz.
cp libz.a /home/.... - that goes ok but then
cp /home/....
cp: missing destination file operand after '/home...'

It's trying to copy nothing to my project folder. I don't know what it is actually and why is it not building.

Anyone had a similar problem or has some clue about this?
I'm using Fedora.

Thanks!


P.S. I have installed wget ,autotools, libtool, cmake, subversion.

[bero7]

hm, ok... "make clean" seems to have done the trick for this but, now a new problem

error while building faad2 lib

Code: Select all

configure.in:14: error: possibly undefined macro: AC_PROG_LIBTOOL If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation.

Any ideas, please? Thanks for the help

Do you have libtool installed on your system?

[bero7]

Yes, I have all the tools. Libtool, autoconf, automake, cmake, wget, subversion, pkgconfig, gettext......

That's why I don't understand..the error's like there would be no libtool but it was even used previously for other libs..

[bero7]

btw, I googled out the exact same output I get, here:

http://pastebin.com/3M24DVhK

but no solution...Anyone ?

[Diamanter]

I had this problem and solved it by installing libtool.

[bero7]

autoreconf --verbose --install solved the faad2 problem..

I managed to get to the part where configure.sh is run

Code: Select all

extras/package/android/configure.sh

BUT

a new error (of course) and no clue on this one.

Code: Select all

checking media/stagefright/OMXClient.h usability... no checking media/stagefright/OMXClient.h presence... no checking for media/stagefright/OMXClient.h... no configure: error: "Could not find IOMX headers"

where are these headers supposed to be?


EDIT:

If I specify --disable-iomx (which I'm not sure is smart but just to get going) then configure finishes BUT it doesn't compile.. :/

Code: Select all

../../extras/package/android/../../../src/posix/thread.c: In function 'vlc_set_priority': ../../extras/package/android/../../../src/posix/thread.c:833: warning: unused parameter 'th' ../../extras/package/android/../../../src/posix/thread.c: In function 'vlc_cancel': ../../extras/package/android/../../../src/posix/thread.c:866: error: implicit declaration of function 'pthread_cancel' ../../extras/package/android/../../../src/posix/thread.c: In function 'vlc_savecancel': ../../extras/package/android/../../../src/posix/thread.c:883: error: implicit declaration of function 'pthread_setcancelstate' ../../extras/package/android/../../../src/posix/thread.c:883: error: 'PTHREAD_CANCEL_DISABLE' undeclared (first use in this function) ../../extras/package/android/../../../src/posix/thread.c:883: error: (Each undeclared identifier is reported only once ../../extras/package/android/../../../src/posix/thread.c:883: error: for each function it appears in.) ../../extras/package/android/../../../src/posix/thread.c: In function 'vlc_restorecancel': ../../extras/package/android/../../../src/posix/thread.c:903: error: 'PTHREAD_CANCEL_DISABLE' undeclared (first use in this function) ../../extras/package/android/../../../src/posix/thread.c: In function 'vlc_testcancel': ../../extras/package/android/../../../src/posix/thread.c:920: error: implicit declaration of function 'pthread_testcancel' ../../extras/package/android/../../../src/posix/thread.c:1223:5: warning: #warning "vlc_GetCPUCount is not implemented for your platform" make[4]: *** [posix/thread.lo] Error 1

so, now if anyone can help here I'd be grateful. Thanks

[bero7]

Ok, android's Bionic C library comes with its own pthread implementation bundled in.
It does not support pthread_cancel or similar...

But ok, I still don't know how to get around this issue.
So vlc is trying to build thread.c from vlc/src/posix and it's relying on pthread.h which is in android-ndk, which of course does not have the needed definitions.


Did anyone here building vlc for android have these issues? Any advice on this? Thanks!

Wondering if you were trying to manually execute step by step according to the install.sh?
I got exactly the same problem - after one failure and tried to continue to compile on a new terminal - by omitting the pre evious successful step according install.sh. My problem was I forgot to export 2 env variable in the new terminal:

export ANDROID_SYS_HEADERS=${PWD}/android-headers
export ANDROID_LIBS=${PWD}/android-libs

after I export them then I can pass this step but I still got JNI compilation error:

still having the headache...

Android Bionic does not come with POSIX threads. It provides an insufficient subset (for VLC, but evidently not for the Dalvik VM) of POSIX threads.

A new VLC threading backend dedicated for Android would be required, which has yet to be written. In the mean time, there is only a an ugly brittle patch that [imostly[/i] works floating around. It should already be in the vlc-android git tree.

[billbylake]

Thanks for the prompt response!
There are currently two git trees for vlc android:
git://git.videolan.org/vlc-ports/android.git
and
git://git.videolan.org/vlc/vlc-android.git
I am using the 1st one. You say that the workaround is in the vlc-android git tree, so i suppose you mean the 2nd one?
I am going to try it...

[Rémi Denis-Courmont]

It should be in both. I know neither of them.

[billbylake]

Tried with latest git, still fails at the same place...
So the ugly patch doesn't seem to work for me, or, how can i make sure if that patch has applied or not?
Another thing i can do is that since speex is causing the problem and it is only an audio coding, so i suppose i can exclude it from the build, but how? There is a "enable-speex" in the configure file. shall i just remove it from there?

[bero7]

billbylake, thanks soo much for the heads up! Indeed, exporting ANDROID_LIBS and HEADERS was in the script but it wasn't executed for some reason
I was also trying to build step by step , but never started from the first step actually cause I thought everything up to "make" completed successfully.

P.S. try --disable-speex

cheers

[billbylake]

bero7, after --disable-speex, plus a bug fix on vlc-network.h I finally got vlc compiled. Thanks!
But the build with default configuration does not seem to include many things in so it does not play a .mp4 file
LogCat says: No access module matching the "file" could be loaded.
Mmm... I need to enable something still...
