[maemo-developers] Working source package/compilation instructions for dsp_dld?

[From: Simon Pickering]

Hi all,

I tried compiling dsp_dld (the DSP dynamic loader daemon) from the  
source in dspgw-3.3-arm.tar.bz2  
(http://prdownloads.sourceforge.net/dspgateway/dspgw-3.3-arm.tar.bz2?download).

This is the correct version of the code as reported by "dsp_dld -v" on  
my N800 running OS2008 beta.

Unfortunately the code doesn't compile as it's lacking at least one  
definition and produces some errors with the kernel headers:

I had previously tried with version 3.3.1 of the code, this includes a  
header file and doesn't seem to have problems with the kernel headers.  
It compiles but when run, it unfortunately crashes the DSP, which is  
not quite the effect I was after. What I am trying to do is modify the  
dsp_dld code to produce some more debugging output to make my life  
easier when developing dsp tasks. E.g. debugging this error:

device ivorbisidec is requesting for TADD.
starting TADD process for device ivorbisidec.
loading /lib/dsp/modules/ivorbisidec.o.
section text: could not find directive. placing it to default memory (DARAM).
section text: size = 0x00002d, align = 0x1 ... no space left in DARAM!
section text: failed to place!
cleaning task ivorbisidec...
unloading /lib/dsp/modules/ivorbisidec.o.

I hope we can just get a source package added to the repo, but if  
that's not possible (or might take a while), I'd be happy with some  
advice as to how to get it to compile and work.

Thanks,


Simon
