"undefined reference to bsd_signal" error on Android Studio 2.1

[Diane Cordero]

Hi Sebastian, 

I have downgraded my NDK to version 11c and am seeing the same 'undefined reference to bsd_signal' error. Which version of the NDK is 1.8.1 guaranteed to be compatible with?

Best,
Diane

Hi,

can you provide an example project that shows this error, and file a bug about it at
  https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer

Also do the Android examples here work for you?
  https://cgit.freedesktop.org/~slomo/gst-sdk-tutorials/tree/gst-sdk/tutorials/
or something using gradle like
  https://github.com/sdroege/gst-player/tree/master/android

Where do you get NDK v12? The latest seems to be still r11c.

What is the target API you used for your project? We build the GStreamer binaries against API version 9 as that is the lowest we require. It should however be forwards-compatible (but maybe it isn't?).

Not specifically, but they're tested with command-line tools, which are the same as called by Android Studio.

There is no difference.
