  • distro is Ubuntu 18.04 (on aarch64, Jetson TX2 to be precise)
  • Clang: 8.0.0
  • CUDA: 10.0
  • Python: 3.6.8 (in case you want to know :P)
  • Boost: 1.65

I built hipSYCL successfully, but when I try to compile a program with syclcc-clang, I get the linker error below:

Hi!

aarch64, always nice to see people trying hipSYCL on some new platform :) The downside is that I don't have any experience on that platform, but let's see if we can get it working :)

clang 8 doesn't support cuda 10 as documented here. You should either upgrade to clang 9 or use CUDA 9.x. Normally, clang refuses to do anything if it has detected an incompatible CUDA version, so I'm surprised you even got to the linking stage. Perhaps on aarch64, this behavior is different.

In any way, I don't think the cuda-clang version mismatch is related to your issue. It seems there is some ABI incompatibility here. I'm not sure if this is even related to hipSYCL. Could you please verify

  • that you can compile C++ programs with clang
  • that you can compile regular CUDA code with clang, e.g. clang++ -x cuda --cuda-gpu-arch=sm_62 ...

If all this works, please describe how you have built hipSYCL and post a dump of your cmake configuration, e.g. cmake -LA <source dir> from your build directory.
It could be that you have compiled hipSYCL with another compiler (e.g. gcc) which has built a runtime library that has an ABI that is incompatible with clang, and so cannot be linked. Normally clang and gcc are binary compatible such that this is not an issue, but if one is very new and the other very old things may be different. In that case, please try compiling hipSYCL with clang 8.

Shouldn't be much of a problem.. I got hipSYCL running on a Jetson Xavier AGX, also aarch64.
It's been CUDA 10 there but 9 should work as well as 10. At the time of doing it, Clang 9 has not been available as packages, but building it was successful.

Yes, I can compile both C++ and CUDA code. I used the following commands to build hipSYCL:

cmake \
	-DCMAKE_C_COMPILER=/usr/bin/clang-8 \
	-DCMAKE_CXX_COMPILER=/usr/bin/clang++-8 \
	-DCMAKE_INSTALL_PREFIX=/opt/hipSYCL/ \
	-DLLVM_DIR=/usr/lib/llvm-8/cmake \
	-DCLANG_EXECUTABLE_PATH=/usr/bin/clang-8 \
	-DCLANG_INCLUDE_PATH=/usr/include/clang/8/include \
	../hipSYCL/

make
sudo make install

And my CMake configuration is below:

Does anything change if you use -DCLANG_EXECUTABLE_PATH=/usr/bin/clang++-8 instead of /usr/bin/clang-8?

Yep, that seems to resolve the issue:

$ /opt/hipSYCL/bin/syclcc-clang test.cpp -o test --hipsycl-platform=cuda --hipsycl-gpu-arch=sm_62 # success!
$ LD_LIBRARY_PATH=/opt/hipSYCL/lib/:$LD_LIBRARY_PATH ./test
Result:

Excellent! Issue was most likely that libstdc++ was not linked by clang because the C++ wrapper was not used. Maybe we should check in cmake that clang is clang++-XX and print a warning otherwise.
