Bug#907069: nvcc problems with gcc

[Stefano Simonucci]

Package: nvidia-cuda-toolkit
Version: 9.2.148-1
Severity: important

Dear Maintainer,
      I can't compile a very simple program

#include <stdio.h>

#define NQ 100
#define PI 3.14159265358979323848
#include <math.h>

// For the CUDA runtime routines (prefixed with "cuda_")
#include <cuda_runtime.h>
#include <curand_kernel.h>

/**
  * Host main routine
  */
int
main(void)
{
     // Error code to check return values for CUDA calls
     cudaError_t err = cudaSuccess;

     // Print the vector length to be used, and compute its size
     int runtimeVersion,driverVersion;
     err=cudaRuntimeGetVersion(&runtimeVersion);
     printf("Error runtime =%d\n",err);
     err=cudaDriverGetVersion(&driverVersion);
     printf("Error version =%d\n",err);
     printf("%d %d\n",runtimeVersion,driverVersion);
     return 0;
}

because I get the following error  from the command   nvcc <name>.cu
/usr/lib/gcc/x86_64-linux-gnu/7/../../../../x86_64-linux-gnu/bin/ld: 
/usr/lib/gcc/x86_64-linux-gnu/7/liblto_plugin.so: error loading plugin: 
/usr/lib/gcc/x86_64-linux-gnu/7/liblto_plugin.so: classe ELF errata: 
ELFCLASS64
collect2: error: ld returned 1 exit status

Next I have tried with the command nvcc -ccbin=clang-4.0 <name>.cu
and the program is correctly compiled.
But in the execution I get
./a.out
Error runtime =35
Error version =0
32765 5000

The output of nvidia-smi is
nvidia-smi
Failed to initialize NVML: Driver/library version mismatch

Previous installation from the .run files (cuda 6.5) was functioning.
nvidia-detect gives
nvidia-detect
