please let me know if should add other file here let understand issue.

multiple libraries cannot found. try find out these libraries located on system.

in makefile, path added ld_flags linker search:

-l$(ndk_root)/platforms/android-9/arch-x86/usr/lib/

first, check if required libraries can found there (e.g. libm.so)

if not, try find out whether somewhere else on system. on linux, libdl.so, libm.so etc. can found in /usr/lib64 (/usr/lib on 32-bit system). if find them, add path ldflags path above:

-l/path/to/libs
