1 year ago This may be related to Ubuntu bug #1939379 (I assume you're using Ubuntu here). Can you try modifying the makefile for the native libraries to pass -march=armv7-a+fp to the compiler and linker instead of -march=armv7-a?

1 year ago You probably need to add +fp to the -march flag for the arm64v8 target on lines 194 and 195, too (i.e., -march=armv8-a+fp):

1 year ago I had already tried -march=armv8-a+fp and it gave me error, so after searching on the web I put arm32v8HF: export LDFLAGS += -with-arch=armv8-a+fp and it worked.
