Takashi: please help (compiling alsa-driver)

[Jonas Petersen]

Hi Takashi,

I'm talking to you directly because this

ftp://ftp.suse.com/pub/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz

is the only alsa-driver source that I'm able to compile so far. I can unpack this and simply run ./configure && make && make install. It works great. (I compile against the kernel-headers from ubuntu).

I spent hours in trying to compile from several other sources.

* The plain1.0.25 release (complains about missing symbols).
* The snapshots fromhttp://www.alsa-project.org/snapshot/  (will complain about missing 'uapi' stuff)
* Btw. where did the snapshots fromhttp://ftp.kernel.org/pub/linux/kernel/people/tiwai/alsa/  go (Advertised here:http://www.alsa-project.org/main/index.php/Download)?
* Checked out alsa-driver from git. But no luck, tried many things. e.g.: Branch release, then autoconf, but not even ./configure succeeds.

Id like to submit some patches and be able to work with the current state from git. How is that supposed to work?

Btw. I often read that the alsa-kernel is needed to compile. But it is not neede with this above mentioned 'unstable-snapshot'. It will just compile against the ubuntu kernel-headers (Lubuntu 12.10).

How do you generate these snapshots?

Thanks and sorry if that's stupid questions..

But there are warning message for four sound card modules  when build in
Ubuntu 12.04 LTS

Section mismatch in reference from the function snd_bt87x_detect_card() to
the variable .devinit.rodata:snd_bt87x_ids
The function snd_bt87x_detect_card() references
the variable __devinitconst snd_bt87x_ids.
This is often because snd_bt87x_detect_card lacks a __devinitconst
annotation or the annotation of snd_bt87x_ids is wrong.

Section mismatch in reference from the function generic_oxygen_probe() to
the variable .devinit.rodata:oxygen_ids
The function generic_oxygen_probe() references
the variable __devinitconst oxygen_ids.
This is often because generic_oxygen_probe lacks a __devinitconst
annotation or the annotation of oxygen_ids is wrong.

Section mismatch in reference from the function xonar_probe() to the
variable .devinit.rodata:xonar_ids
The function xonar_probe() references
the variable __devinitconst xonar_ids.
This is often because xonar_probe lacks a __devinitconst
annotation or the annotation of xonar_ids is wrong.

Do the latest version of alsa-lib require any specific parameter to install
on Ubuntu 12.04 for testing the channel map ?

alsa-lib/test/chmap -D hw:0 query

What is the proper way to build from git since alsa-driver-build.git only
contain README

The snapshot in alsa-project.org is also unusable

You need to have two git trees: sound.git tree containing the complete
Linux kernel tree, and alsa-driver-build.git containing only the build
stub for external builds.

In the recent change, alsa-driver-build.git (or equivalent with
alsa-driver.git in alsa-project.org) contains only README in master
branch.  Checkout build branch instead.  Then you'll get the whole
build stuff in alsa/ subdirectory.  Go into alsa subdirectory, then
run
	ALSAKERNELDIR=../../sound ./gitcompile --with-debug=full --enable-dynamic-minors

Alternatively, you can pull the alsa-driver-built git into kernel tree
directly.  Then go to alsa subdirectory and run gitcompile.  In that
case, you can omit passing "ALSAKERNELDIR=..." argument.

These errors can be ignored.
It happens because __devinit* stuff have been dropped in the
upstream kernel.

Seem you didn't install the conf_pulse module properly, no?

The build stuff is included in build branch as seen in README.

Did you pass the proper --libdir option to configure script when you
build & install alsa-lib?

Thank you very much, that did help!

It didn't exactly answer my distinct question ("How do you generate 
these snapshots?"), but I was able to figure it out by myself now.

After some manual copying and linking and investigating I finally found 
what I need need to do:

$ ./utils/setup-alsa-kernel -c ../../sound

After that I can copy just the 'alsa' folder to another machine and it 
wil build.

The problem is, this procedure requires 1.6 GB of disk space. I'm 
building on another system that does not have that much space right now. 
The mentioned snapshot (and now the result from the 'setup-alsa-kernel' 
script) is consuming only about 100 MB after a full build.

These are all steps required:

~$ mkdir tiwai; cd tiwai
~/tiwai$ git clone git://github.com/tiwai/alsa-driver-build.git
~/tiwai$ git clone git://github.com/tiwai/sound.git
~/tiwai$ cd alsa-driver-build
~/tiwai/alsa-driver-build$ git checkout build
~/tiwai/alsa-driver-build$ cd alsa
~/tiwai/alsa-driver-build/alsa$ ./utils/setup-alsa-kernel -c ../../sound

Now the alsa folder contains everything needed.
Finally:

some-other-machine/alsa$ ./gitcompile --with-debug=full 
--enable-dynamic-minors
