   > @hengdos I was trying to reproduce this issue on Mac and Ubuntu. But I was not able to invoke 'make' while building the 'transformer' with statically linked libraries. Can you please ensure that CMakelist.txt for static library is correct?
   > I will try it again as well.
   
   @leleamol hi, I have tested the following CMakelist.txt for static library on macOS Mojave 10.14.3.
   
   ```
   cmake_minimum_required(VERSION 3.9)  
   
   set (CMAKE_CXX_STANDARD 11)
   
   add_executable(transformer
           main.cc
   )
   
   target_link_libraries(transformer
           ${PROJECT_SOURCE_DIR}/lib/libmxnet.a
           ${PROJECT_SOURCE_DIR}/lib/libdmlc.a
           ${PROJECT_SOURCE_DIR}/lib/libnnvm.a
   )
   
   target_include_directories(transformer PUBLIC
           ${PROJECT_SOURCE_DIR}/include
   )
   ```
   
   The output is like this:
   ```shell
   $ ./transformer 
   net-symbol.json ... 954 bytes
   net-0000.params ... 164 bytes
   Assertion failed: (pred_hnd), function main, file /Users/heng/Projects/lrcplus/main.cc, line 101.
   [1]    30126 abort      ./transformer
   ```
   
   Thanks for your reply.
