[CELT-dev] C55xx Linking Error

[Mike Hooper]

I am attempting to port CELT to the TI C5515 DSP. I am
compiling/assembling/linking with Code Composer Studio 4. I have enabled the
TI_55 specific optimizations in my config.h file per this
<http://lists.xiph.org/pipermail/celt-dev/2008-December/000033.html>  post.
However, I am getting several "undefined symbol" linking errors that do not
make sense to me. According to the error message, these all appear to be
part of mdct.obj. But looking at the code in mdct.c, there is no reference
to "alloca". Nor have I defined "USE_ALLOCA" since the TI complier does not
support it. Can anyone spot an error on my part, or is this yet another
quirk of the CCS4 suite (there have been many).

 

Here's a listing of the console error messages.

 

undefined        first referenced


  symbol              in file

================================================

 

Any help would be much appreciated.
