Link error when building libvpx on MacOS for Android x86 #798

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I am trying to build the latest libWebM on MacOS for Android x86. I follow the 
instructions in 
http://git.chromium.org/gitweb/?p=webm/bindings.git;a=blob;f=JNI/README.Android,
 with arm replaced by x86.

The libvpx is configured as: --force-target=x86-android-gcc --disable-ssse3 
--disable-sse4_1 --disable-avx2 --disable-examples 
--sdk-path=/Downloads/android-ndk-r9d/

But I got a bunch of linking errors as shown below, The entire build log is 
attached.

/Volumes/DATA/mac/depot/webm/jni/vp8_rtcd.h:478: error: undefined reference to 
'vp8_bilinear_predict16x16_sse2'
/Volumes/DATA/mac/depot/webm/jni/vp8_rtcd.h:480: error: undefined reference to

This error is strange:
Android NDK: WARNING: Unsupported source file extensions in 
/Volumes/DATA/mac/depot/webm/jni/libvpx/build/make/Android.mk for module vpx    

The NDK added support for yasm only very recently. I'm trying to reproduce your 
issue now. Can you confirm what checkout of libvpx you are using?
