Compilation of flann with use-enabled cuda flag fails, at least with nvidia-cuda-sdk 8.0 installed. The relevant bit appears on the following nvcc invocation: /opt/cuda/bin/nvcc -M -D__CUDACC__ /var/tmp/portage/sci-libs/flann-1.9.1/work/flann-1.9.1/src/cpp/flann/algorithms/kdtree_cuda_3d_index.cu -o /var/tmp/portage/sci-libs/flann-1.9.1/work/flann-1.9.1_build/src/cpp/CMakeFiles/flann_cuda_s.dir/flann/algorithms/flann_cuda_s_generated_kdtree_cuda_3d_index.cu.o.NVCC-depend -m64 -DFLANN_STATIC -D_FLANN_VERSION=1.9.1 -Xcompiler ,\"-O2\",\"-march=native\",\"-mtune=native\",\"-pipe\",\"-fopenmp\" -O2 -v --compiler-bindir /usr/x86_64-pc-linux-gnu/gcc-bin/5.4.0 --compiler-options "-O2 -march=native -mtune=native -pipe" --linker-options -O1,--as-needed ,-arsch -DFLANN_USE_CUDA -Xcompiler -fPIC -DNVCC -I/opt/cuda/include -I/var/tmp/portage/sci-libs/flann-1.9.1/work/flann-1.9.1/src/cpp nvcc fatal : A single input file is required for a non-link phase when an outputfile is specified Notice the space between the linker-options and ",-arsch" that was appended in the ebuild?
