Problem in alsa code

[Vandy]

Hi All,
I am getting the following errors when compiling alsa for the latest
repository. Please help.

I am compiling android code for arm, when compiling in sound I am
getting the following errors.

Hi Vandy,

I am also getting the same error while compiling. Were you able to
make any progress on this?

If so please feel free to share the solution

[Sean McNeil]

Google has made some minor changes to the audio interface and Wind River
is aware of them. There is a patch pending and it will hopefully be
committed soon.

Sorry for the inconvenience,
Sean

[Vandana Vuthoo]

Hi Sean,

When will the patch be available ? I am in a total fix,please help,Can I get some workaround it for it?

Rgds,
Vandana

[Sean McNeil]

Attached is an unofficial patch that should help. We still need to go
through our review process, so things will take time.

Hi sean,

Do you know about changes to the audio interface made by Google? When
was this made?

Please let me know

[Sean McNeil]

Essentially, they added a method to audio out for getting the latency of
audio output. I assume it is for video/audio sync. They also added a
standby method to the input stream. That I assume is for power
management. The open stream methods have an extra argument to get the
status back on open. Finally, they made the AudioHardwareInterface class
a pure template class and made AudioHardwareBase what used to be
AudioHardwareInterface.

All these changes appear to be helpful and desirable.

Hi Sean,
Now when I build I am getting the following error
target arm C++: libaudio <= hardware/alsa_sound/AudioHardwareALSA.cpp
make: *** No rule to make target `out/target/product/generic/obj/STATIC_LIBRARIES/libasound_intermediates/libasound.a', needed by `out/target/product/generic/obj/SHARED_LIBRARIES/libaudio_intermediates/LINKED/libaudio.so'.  Stop.


Rgds,

Thanks Sean,
  We tested it and found that, it is working nicely. Now we are able to compile build and play sound.

Hi Sean/Rupesh,
I applied the same patch but got the foll errorrs

ow when I build I am getting the following error
target arm C++: libaudio <= hardware/alsa_sound/

AudioHardwareALSA.cpp
make: *** No rule to make target `out/target/product/generic/obj/STATIC_LIBRARIES/libasound_intermediates/libasound.a', needed by `out/target/product/generic/obj/SHARED_LIBRARIES/libaudio_intermediates/LINKED/libaudio.so'.  Stop.

please help.

You are probably missing external/alsa-lib. You have to have both.

Hi,
I have taken external/alsa-lib, but still facing the same issue,
Rgds,

[Rupesh Gujare]

Vandana,
  Try cleaning your build or take fresh build and recompile, might be your build is little screwed up.

Thanks for the patch Sean, but I'm still getting an error:

target arm C++: libaudio <= hardware/alsa_sound/

AudioHardwareInterface.cpp

hardware/alsa_sound/AudioHardwareStub.cpp: In member function 'virtual

following virtual functions are pure within

Any fix?

[Sean McNeil]

Yes, I noticed this as well. Seems like the patch I sent you was a
little messed up. Just copy over the files from

./frameworks/base/libs/audioflinger/AudioHardwareStub.*

and you should be OK.

Thanks so much. It works ;)

Hi HarishKumar.V,

You can find these functions in hardware/libhardware_legacy/power/power.c
