[osg-users] Android build failure with Android NDK r13

[Rafa Gaitan]

Hi Andy,

The toolchain for cmake in osg is probably not updated since the ndk r10e.
Unfortunately I'm not working anymore in Android and I don't have time for
take a look at it.

I used the toolchain file from the opencv project, so probably updating it
with that file will fix that problem

Best regards,
Rafa.
