Hi,

I just want to see if there has been any success building VLC Android so far.

I had to make a dozen patches to the code (from <inttypes> inconsistencies to OpenGL not being loaded), but I still can get around it (now I'm stuck trying to figure out why libarchive doesn't get picked up by the linker).

Just making sure if my C skills are rustier than expected, or I should try on Ubuntu.

Thanks.

EDIT: Here is and extract of the latest build error I'm getting:

You are missing some -l flags in the ANdroid.mk file.

Well spotted! Had to add both -larchive and -lGLESv1_CM (and change <GL/gl.h> to <GLES/gl.h> in glspectrum.c).
Now I'm having a declaration conflict between libzip and libaccess:

Code: Select all

arm-linux-androideabi/bin/ld: error: VLC/.modules/build-android-arm-linux-androideabi/libzip_plugin.a(libzip_plugin_la-zipstream.o): multiple definition of 'StreamOpen'

arm-linux-androideabi/bin/ld: VLC/.modules/build-android-arm-linux-androideabi/libaccess_archive_plugin.a(libaccess_archive_plugin_la-stream.o): previous definition here

My question is, would building on Linux be much smoother than this?

Posted: **18 Jul 2015 20:02**

yes, it would.

Do you have objcopy on your OS X?

Yes... But it turned out building on OSX isn't just hard, but would compromise most of the core code.
I just started fresh on a Ubuntu VM.
Thanks JB!
