# Cuda and current compilers
NVidia is archaic as f..., so they don't officially support any current compiler.

but I found a bunch of ugly hacks to make it work with:
* gcc 7.3.0
* cuda 9.1.85_387.26
  * install from the `.run` file with argument `--override` so it asks you if you're ok with having an unsupported system instead of failing because you're not using ages old ubuntu :P
  * install the CUDA toolkit, but not the (often older than OS provided) GPU driver and not the examples.
  * also install to `/opt/cuda-9.1` because your're not your package manager and it doesn't belong into `/usr/`!
  * then comment out line 121 of `/opt/cuda-9.1/include/crt/host_config.h` (the one `#error`ing about unsupported gcc version)
* ugly low level include file hack:
  * edit `/usr/include/bits/floatn.h`, adding the following after the `#if/#else/#endif` block that sets `__HAVE_FLOAT128`:
```C
#if CUDART_VERSION
#undef __HAVE_FLOAT128
#define __HAVE_FLOAT128 0
#endif
```
