some native popular libs: libffmpeg, libfreetype, libjs (spidermonkey), libogg, libpng, libjpg, libOpenJPEG, zlib

[gacon]

hi all,

I need some popular libs (I think) for my project: libffmpeg,
libfreetype, libjs (spidermonkey), libogg, libpng, libjpg,
libOpenJPEG, zlib. I don't know if these libs were supported on
android and we can load them from NDK?

Thanks,

[appforce.org]

Some of these are already in Android's source tree, and you can pick
them up as static libraries. For ffmpeg there are tutorials over the
net, I don't know about SpiderMonkey.

Hi,

where we can find these libs in the source tree? I downloaded Android source code from: http://git.source.android.com/?p=platform/frameworks/base.git;a=snapshot;h=HEAD;sf=tgz

thanks,

Hello Android!

I don't think you'll find such libs in the frameworks. For libpng, zlib, etc..
check out platform/external/* at http://android.git.kernel.org/

got it, thank you Olivier.

But I think that Google'docs (http://source.android.com/source/git-repo.html) should be changed from "curl http://android.git.kernel.org/repo ~/bin/repo"  to "curl http://android.git.kernel.org/repo > ~/bin/repo"

Hi,

Can someone help me to create Android.mk for libjs (javascript engine / spidermonkey: https://developer.mozilla.org/En/SpiderMonkey/Build_Documentation ). Android.mk was made from Makefile.ref, but I got  lot of error from ndk-build in the code. I also tried to remove *.h from Android, but the same error. I build this lib for Linux, everything is ok.

I attach some necessary mk file.

Thanks,

hi,

I downloaded some libs from this repository and tried to compiled them. With the libs that have only one include $(BUILD_SHARED_LIBRARY) (or static) in the Android.mk, everything is ok. But with the libs that have more than one include, ex:

[CODE]

LOCAL_MODULE := libz

LOCAL_CFLAGS += -O3 -DUSE_MMAP

LOCAL_SRC_FILES := $(zlib_files)

include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_ARM_MODE := arm

LOCAL_MODULE := libz

LOCAL_CFLAGS += -O3 -DUSE_MMAP

LOCAL_SRC_FILES := $(zlib_files)

include $(BUILD_STATIC_LIBRARY)

include $(CLEAR_VARS)

...

[/CODE]

I got the message:

[CODE]

gacon@gacon-laptop:~/workspace/zlibdroid/jni$ ndk-build 

Android NDK: Trying to define local module 'z' in /home/gacon/workspace/zlibdroid/jni/Android.mk.    

Android NDK: But this module was already defined by /home/gacon/workspace/zlibdroid/jni/Android.mk.    

/home/gacon/android/android-ndk-r4b/build/core/build-static-library.mk:33: *** Android NDK: Aborting.    .  Stop.

[/CODE]

How to fix this? Thanks,

Luyen,
