Clarity regarding Altera OpenCL basics

Hi all, I started my foray into OpenCL through GPUs, such as nVIDIA or AMD graphics cards. However I've recently moved onto research using FPGAs. Unfortunately even after querying the usual s...

Hi all,

Thank you for the continued support. I managed to find out what was going on, and embarrassingly admit that I made a mistake in some post-scripts in the makefile of my C files, whereas the makefile for my C++ files was correct.

It is curious that the Altera OpenCL SDK does not use the libOpenCL.so and so linking with the -lOpenCL flag is useless, but I guess that just comes with the unfamiliarity as I migrate over to OpenCL development in FPGAs.

Now I usually link with 

>> aocl link-config
-L/opt/altera/14.0/hld/board/terasic/de5net/linux64/lib -L/opt/altera/14.0/hld/host/linux64/lib -lalteracl -ldl -lacl_emulator_kernel_rt  -lalterahalmmd -laltera_apb_14_0_mmd -lelf -lrt -lstdc++

and the compilation goes ahead just fine.

As I said, the problem was in some silly mistake in some post-script. On the positive side, this counts as an enlightening experience, more or less, haha.

Thank you again for the insight,

Victor
