Hi,

it seems very likely, that this is the problem.

This

aocl_mmd_get_offline_info(
	AOCL_MMD_VERSION,
	sizeof(mmd_version),

	&param_size_ret
);

gave me version 14.1, so it seems the terrasic BSP ships with a very old mmd library.

Can I compile a newer MMD library from sources included in the Intel FPGA SDK for OpenCL or can I simply copy some ".so" file?

Edit: I just saw, that section 1.4.3. of ug_aocl_custom_platform_toolkit.pdf describes, how to create the mmd library, I'll try that next.
