loki fd1026 113 clang -v
clang version 5.0.0 (branches/release_50 310243)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/local/llvm-trunk/bin
Found candidate GCC installation: /usr/lib64/gcc/x86_64-suse-linux/4.8
Selected GCC installation: /usr/lib64/gcc/x86_64-suse-linux/4.8
Candidate multilib: .;@m64
Candidate multilib: 32;@m32
Selected multilib: .;@m64
Found CUDA installation: /usr/local/cuda, version 8.0
My current version didn't build "libomptarget", but I've had the same error for
a CUDA device in an older version. The old version worked for the target
"x86_64-pc-linux-gnu".
