Expected top-level entity error after installing hipDNN with gem5 library

Description

After installing hipDNN in gem5 docker image, I compiled square.cpp:
make gfx8-apu

Error occured:

mkdir -p ./bin
/opt/rocm/hip/bin/hipcc --amdgpu-target=gfx801 square.cpp -o ./bin/square.o
Name "main::EXPORT_LL" used only once: possible typo at /opt/rocm/hip/bin/hipcc line 219.

The version of hipDNN is commit 6ab7aaaa7b90845b43c3241eb9c500e1929d8503 which is consistent with MIOpen version. When compiling square.cpp, hipdnn is not even used. This problem did not occur before installing hipdnn.

Environment

Ubuntu 18.04
gem5 20.1.0.5
hipdnn commit 6ab7aaaa7b90845b43c3241eb9c500e1929d8503

I have never gotten hipDNN to work, even with a supposedly compatible version of MIOpen – if I remember correctly hipDNN needed libraries that required newer versions of ROCm. The last hipDNN commit I tried was:

    RNN API support for ROCm backend

It’s possible you found a way around the linking and compilation issues we had, but either way hipDNN is not supported so I don’t have any simple answers, sorry.

I noticed that you’re running on Ubuntu 18 though – currently ROCm 1.6 requires gcc 5.4 which is not installed by default in Ubuntu 18. Are you actually running the docker (which uses Ubuntu 16 and gcc 5.4 internally) on a machine that runs Ubuntu 18? If not, this seems like a more basic problem with gcc version. Or did you update the docker to use Ubuntu 18 instead? You mentioned that you were able to compile square before adding hipDNN though, so I suspect this is not the case.

EDIT: go with Kyle’s answer instead, much more likely.

There’s a bug in hipcc when you’re compiling a .o file when it’s already built

The solution is to either change the Makefile command to output as

instead of

Alternatively, you should be able to either delete the bin directory, or re-run the make command.
