Bug ID: 35692
Summary: Fails to compile documentation example on MacOSX
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: CUDA
Assignee: unassignedclangb...@nondot.org
Reporter: gonzalob...@gmail.com
CC: llvm-bugs@lists.llvm.org
I've installed MacOSX high sierra, updated xcode, installed latest cuda (CUDA
9.1), and when trying to compile the documentation example in:
https://llvm.org/docs/CompileCudaWithLLVM.html#invoking-clang
like this:
clang++ axpy.cu -o axpy --cuda-gpu-arch=sm_35 -L/usr/local/cuda/lib -lcudart
-ldl -lrt -pthread
it fails to compile with the following error:
clang-6.0: error: cannot find libdevice for sm_35. Provide path to different
CUDA installation via --cuda-path, or pass -nocudalib to build without linking
with libdevice.
I've tried passing clang --cuda-path=/usr/local/cuda/ and also
--cuda-path=/Developer/NVIDIA/CUDA-9.1/ without any luck.
The paths in /usr/local/cuda all link to /Developer/NVIDIA/CUDA-9.1/.
