Trouble installing gpuR on Ubuntu ppc64le - r

Question

I am trying to install gpuR on Ubuntu 16.04 LTS ppc64le (IBM POWER8), but crashed into an error which says "vector’ does not name a type".
Can you pls help me out ? Any comment would be much appreciated.

I solved this specific trouble by modifying cl_platform.h included in gpuR_1.2.1.tar.gz. I simply changed "typedef vector" in the following into "typedef __vector".

u0017649#sys-87458:~$ tar -zxvf gpuR_1.2.1.tar.gz
u0017649#sys-87458:~$ cd gpuR/inst/include/CL
u0017649#sys-87458:~/gpuR/inst/include/CL$ vi cl_platform.h
#include <altivec.h> /* may be omitted depending on compiler. AltiVec spec provides no way to detect whether the header is required. */
typedef vector unsigned char __cl_uchar16;
typedef vector signed char __cl_char16;
typedef vector unsigned short __cl_ushort8;
typedef vector signed short __cl_short8;
typedef vector unsigned int __cl_uint4;
typedef vector signed int __cl_int4;
typedef vector float __cl_float4;
