Hey y'all,

I'm building a dynamic module I want to invoke using FastRPC in the same fashion as the calculator_c++14 sample, but I also need to utilize the hvx units. In order to do so, I've added a dll dependency to libdspCV_skel.

I'm currently trying to get something stood up in the simulator as I don't yet have the hardware available.

When I try and load my module (libMageDSP_skel.so) from my QEXE (using dlopen) it fails because it says the HAP and qurt symbols are undefined in the libdspCV_skel.so.

Another weird thing is that when I add libdspCV_skel as a dependency, when loading my .so it says I also require libapps_mem_heap.so as a dependency which isn't referred to anywhere in the sdk. Adding that so as a dependency then gets me to this state where there are a bunch of unresolved symbols.

The variant I'm using is hexagon_Release_dynamic_toolv80_v62. (sdk windows 3.2)

Thank you for you help,

Julien.

I know, I found it and linked it in as I said in my post. I just thought it was was weird that no other sample was using it yet I had to and thought I'd mention it.
