error: uses VFP register arguments, output does not

[hgffly]

I have built OpenBLAS libraries successfully. But when I put the libraries in my Android project and try to build it, an error is raised:

Error:error: ../../../../src/main/jniLibs/armeabi-v7a/libopenblas.a(cblas_sasum.o) uses VFP register arguments, output does not
Error:error: ../../../../src/main/jniLibs/armeabi-v7a/libopenblas.a(openblas_env.o) uses VFP register arguments, output does not

What's the matter with it?
How could I resolve it? thanks

How did you build openblas?

I built the openblas in the way you mention in the page, with export ANDROID_ABI=armeabi-v7a-hard-softfp with NEON. But I just found the libraries of OpenBLAS is built with some errors, the error messages are as below :

My OS is Ubuntu16.04, NDK is android-ndk-r11c, cmake version 3.5.1
The README.md says you Tested with Android NDK r11c and cmake 3.3.2 on Ubuntu 14.04
Do I need to have identical settings as yours?
If not , how can I resolve the errors ? Thanks very much
