Re: [SlimDevices: Jive] Compile SqueezeOS for "Baby" - missing babydsp.so (BB/Poky recipe - Private_SVN)

[ralphy]

I've managed to workaround the missing private babydsp sources to
successfully build the radio firmware.

Copy /usr/lib/alsa-lib/libasound_module_pcm_babydsp.so from a radio to
your poky build system and rename it using scp.


Code:
--------------------
    $ scp -p root@radio:/usr/lib/alsa-lib/libasound_module_pcm_babydsp.so 
libasound_module_pcm_babydsp.so.0.0.0
  
  libasound_module_pcm_babydsp.so      100%   33KB  33.5KB/s   00:00
--------------------


Create a tar file which contains the renamed babydsp module in the
correct folder structure.  I included the firmware version of the radio
where the shared library came from in the filename.


Code:
--------------------
    $ tar -tzvf babydsp-7.7.3r16676.tar.gz
  
  drwxr-xr-x ralphy/ralphy     0 2020-02-05 16:31 squeezeos_dsp/
  drwxr-xr-x ralphy/ralphy     0 2020-02-05 16:10 squeezeos_dsp/.libs/
  -rw-r--r-- ralphy/ralphy 34271 1969-12-31 19:00 
squeezeos_dsp/.libs/libasound_module_pcm_babydsp.so.0.0.0
--------------------


Create an md5 checksum file


Code:
--------------------
    md5sum babydsp-7.7.3r16676.tar.gz > babydsp-7.7.3r16676.tar.gz.md5
--------------------


Put both files in the poky/sources folder

Update squeezeos-dsp-src_svn.bb.  We only want bitbake to perform the
install step.  File attached.

I used a url to a local apache server running on my build VM in the
SRC_URI to host the files, but bitbake won't try to download them as
long as the tar and md5 files are already in poky/sources.

Set MACHINE ?= "baby" in poky/build/conf/local.conf

Setup your bitbake environment variables and run bitbake.
