Altera RTE for OpenCL - Manual (Page 28)

Building the Host Application
Build the host executable with the >/hello_world/
Makefile file.
To build the host application, perform the following tasks:
1. Navigate to the
hello_world directory.
2. Invoke the
$ make -f Makefile
command. Alternatively, you can simply invoke the
make
command.
The hello_world executable will be in the >/hello_
world/bin directory.
Running the Host Application
To execute the OpenCL kernel on the FPGA , run the Linux host application that you built from the
Makefile .
1. Add the path
$ALTERAOCLSDKROOT/host/linux64/lib to the LD_LIBRARY_PATH environment variable.
2. At a command prompt, navigate to the host executable within the
>/hello_world/bin directory.
3. Invoke the
hello_world executable.
The hello_world executable executes the kernel code on the FPGA.
Output from Successful Kernel Execution
When you run the host application to execute your OpenCL kernel on the target FPGA, the RTE notifies
you of a successful kernel execution.
Example output:
