Hi @yanghaiping1993 , thanks for getting in touch.
Were those library files i.e. libarmnn.so/libarmnnTfParser.so compiled in 64 bit by any chance? That could explain the incompatibility errors you are seeing above.

I see you are attepting to compile mnist_tf.cpp ( -m32 ) in 32bit, so perhaps that is the issue.

@SaoirseARM it is 32 bit lib, and the error is made by choosing wrong compiler，and I choose the arm-linux-androideabi-clang/clang++，reedit the Makefile，it works well on arm32 device (android OS) if I compile with cmake command:-DARMCOMPUTENEON=0 -DARMCOMPUTECL=0. BUT, if I compile with cmake command:-DARMCOMPUTENEON=1 -DARMCOMPUTECL=0, the log are showed as:
Running 542 test cases...
unknow location(0): fatal error: in "NeonTimerInstrument/NeonTimerMeasure": std::bad_alloc: std::bad_alloc
/armnn-devenv/armnn/src/armnn/test/NeonTimerTest.cpp(35): last checkpoint: "NeonTimerMeasure" entry

*** 1 failuer is detected in the test module "UnitTests"
My android device is an armv7a 32 bit cpu, and RAM is 2GB, what can cause that error?
