Need to Downgrade to gcc 7 to build lib with cuda

FernOfGitHub commented 6 years ago

FYI

when running 'make' in lib, nvcc complained that it could not find a version of gcc 7 or less. I am running version 8.1

I created at the parent of lib & tools /cuda/bin. In bin 'ln -s gcc' In /lib/setup.py I added the argument "--compiler-bindir=../cuda/bin" to extra_compile_args= for nvcc.

This removed the compiler complaint from nvcc.

Thanks. Interesting! Does your symbolic link point to a gcc 7 (or less), or does it still use gcc 8.1. Just wanted to know if the error is because nvcc does not work with gcc 8.1 or is it because it cannot locate any gcc.

The symbolic link points to gcc-7. nvcc complains in host_config.h that the gcc compiler must be 7 or less. Part of #if GCNUC ... #error ...

I am closing this ticket as the ClaRAN v0.2 is out (perhaps checkout if you have some time), and it does not require extra CUDA code to do NMS or other bounding box calculations.
