Other Parts Discussed in Thread: OMAP3530
I am using DSPLink and its make system to build projects for the OMAP3530.
DSPLink and its sample applications run fine.
I installed DSPLIB version dsplib_c674x_3_1_0_0_Linux in order to integrate its C-callable functions into the DSP-side code. This is the problem I'm running into:

The routine I'm calling is DSP_add32. I don't fully understand the linking process, so I do not know where the underscore (_) is being prepended. I read on a different thread that a way to resolve it might be to add _DSP_add32 = DSP_add32 as an object alias to the cfg.cmd file. The only problem is that it's a generated file, and I don't know where or how it's getting generated.
I am adding the /lib directory of DSPLIB to OSLIB_PLATFORM in c64xxp_5.xx_linux.mk, just as I added the /inc directory to OSINC_PLATFORM (and it compiles just fine).
Thanks for any help in advance.
