Cannot install OpenCL R package

[strategist922]

Hi,

I try to install OpenCL R package in Windows 10 Enterprise X64 with Microsoft R Open 3.3.3 and RStudio. May I know how to solve this issue?

Following are the error messages:

You'll need to tell the compiler where to find the header file CL/opencl.h and later where to find the library libOpenCL.a. I can't tell you where they are, but you probably find them in the Intel SDK.

Then change src/Makevars as follows

PKG_CFLAGS=-I<directory containing CL/opencl.h>
PKG_LIBS=`if test -z "$${PKG_LIBS}"; then if uname|grep -i darwin >/dev/null; then echo '-framework OpenCL'; else echo '-lOpenCL'; fi; else echo "$${PKG_LIBS}"; fi` -L<directory containing libOpenCL.a>

in a local copy of the package and build from there.

However, last time I tried this on Windows, it still didn't work. You may need to apply additional changes. Unfortunately, I don't have a Windows machine any longer, but I remember that this worked on Windows 7.

See NEWS on how to set necessary environment variables.

I try it but the result seems. Help me.

Do you have any details? You have to set OCL to point to your SDK and make sure you have the correct Rtools installed to build R packages. If you need any help, you have your exact invocation, settings and any errors you get.
