Run the deployment with all in one packed library… 10: lib/cpp_deploy_pack: not found
Run the deployment with all in normal library… 13: lib/cpp_deploy_normal: not found

how to solve this problem? thanks


This is weird, the normal behavior of the code should be something like:

Build the libraries..
g++ -c -std=c++11 -O2 -fPIC -I/tvm/include -I/tvm/dmlc-core/include -I/tvm/dlpack/include  -o lib/libtvm_runtime_pack.o
g++ -std=c++11 -O2 -fPIC -I/tvm/include -I/tvm/dmlc-core/include -I/tvm/dlpack/include  -o lib/cpp_deploy_pack lib/test_addone_sys.o lib/libtvm_runtime_pack.o -L/tvm/build -ldl -lpthread
g++ -std=c++11 -O2 -fPIC -I/tvm/include -I/tvm/dmlc-core/include -I/tvm/dlpack/include  -o lib/cpp_deploy_normal lib/test_addone_sys.o -L/tvm/build -ldl -lpthread -ltvm_runtime

I think the problem is caused by TVM compilation with llvm, I build TVM from source, but I don’t know why. I rebuild TVM with llvm-5.0, it’s solved now. Thanks for your reply.


For LLVM, any version above 4.0 should be fine.
