The OpenCL support for the nu+ architecture is made through pocl.
How to install vanilla pocl
- Download following the link.
- In order to build pocl, you need the following support libraries and tools:
- Latest released version of LLVM & Clang
- GNU make
- libtool dlopen wrapper files (e.g. libltdl3-dev in Debian)
- pthread (should be installed by default)
- hwloc v1.0 or newer (e.g. libhwloc-dev)
- pkg-config
- cmake
- libclang-3.8-dev if you are using Ubuntu 16.04 LTS
- On Ubuntu 16.04 LTS you can run the following code on a terminal
-
sudo apt-get install llvm & clang & libltdl3-dev & libhwloc-dev & libhwloc-dev & libclang-3.8-dev & make & cmake
- Build and install
-
cd <directory-with-pocl-sources> mkdir build cd build cmake [-D<option>=<value> ...] .. make && make install
-
