tensorflow: Error with building clang unknown argument

I configured project for building and execute next command in project directory:

bazel build -c opt --config=cuda //tensorflow/cc:tutorials_example_trainer

After that i get this error:

ERROR: /home/eugeny/Git/tensorflow/tensorflow/core/kernels/BUILD:3614:1: C++ compilation of rule ‘//tensorflow/core/kernels:multinomial_op_gpu’ failed: clang failed: error executing command /usr/bin/clang -MD -MF bazel-out/local_linux-py3-opt/bin/tensorflow/core/kernels/_objs/multinomial_op_gpu/tensorflow/core/kernels/multinomial_op_gpu.cu.d … (remaining 142 argument(s) skipped): com.google.devtools.build.lib.shell.BadExitStatusException: Process exited with status 1. clang: error: unknown argument: ‘-nvcc_options=relaxed-constexpr’ clang: error: unknown argument: ‘-nvcc_options=ftz=true’ clang: error: cannot find libdevice for sm_35.

Provide its path via --cuda-path, or pass -nocudainc to build without CUDA includes. Target //tensorflow/cc:tutorials_example_trainer failed to build

I’m trying to build it with gpu support by using next libs:

Bazel: 0.5.1 gcc: 7.1.1 Cuda: 8 (version of cuda/bin/gcc is 5.4.0) CUDNN: 6 protobuf: 3.3.1

What shall i change for normal building?

The build currently also fails because of an error in configure script. The fix should be upstream soon, the workaround before it lands is to change the following lines of .tf_configure.bazelrc from:

build --config=cuda
test --config=cuda

to:

build --config=cuda_clang
test --config=cuda_clang

This should be done after running configure.

Please use --config=cuda_clang after configuring to build using clang. (I also think that using bazel build without --config flags should work too). We should add a check for that and provide a helpful error message.

Ah sorry, didn’t realize you were still asking for help.

Can you fill out the new issue template please? In particular what OS are you using?

@gunan it looks like clang/gcc versions aren’t documented, do you know if/when we expect building with clang to work?
