Building OpenCL API Host Code for x86

The AMD Vitis™ application acceleration development flow also supports the use of OpenCL API to program your host application. Building OpenCL applications using g++ uses the following command line: 
g++ -g -std=c++1y -I$XILINX_XRT/include -L$XILINX_XRT/lib -o host.exe host.cpp \
-lOpenCL -pthread

The only difference is the use of the OpenCL library for the OpenCL API in place of the xrt_coreutil library for the XRT native API.

Note: In Vitis Accel_Examples you can see the addition of xcl2.cpp source file, and the -I../xcl2 include statement. These additions to the host program and g++ command provide access to helper utilities used by the example code, but are generally not required for your own code.
