Re: Building alsa with kernel 2.6 when O= option used.

[Eliot Blennerhassett]

Well it seems I am talking to myself here... and so I shall continue.

The only way I have got alsa 1.0.5 driver to compile as an ordinary user is to
get my own copy of the source tree, configure and build that, then continue to
build the alsa driver.

Following the instructions here helped
	http://alsa.opensrc.org/index.php?page=AlsaBuild2.6

So I am on my way again, but I still think there is a bug in the build system
that doesn't allow for Alsa build to work with "O=<path to my dir" kernel
builds. I.e. avoiding taking an actual copy of the whole kernel source tree into
<path to my dir>

regards

Eliot

A kind of 'O=' hack was added for SUSE kernel in the recent version.
It would be nicer to have a generic solution for such a situation,
though, e.g. a new configure option.

Hi, 

I got a bit further

> should I be able to build alsa 1.0.5a if I have built the kernel as follows?
> #cd /usr/src/linux
> #make O=~/build/kernel

To get configure to work, I had to copy ~/build/kernel/include/linux/* to the
corresponding dir in /usr/src/linux
(I shouldn't have to do this, instead something like 
	configure --with-kernel-build=~/build/kernel
)

Then
 make O=~/build/kernel

appears to be working, until it conks out building acore/memalloc.c

/acore/memalloc.c:63: error: conflicting types for `snd_malloc_sgbuf_pages
(but I seem to remember a thread about this, need to hunt back through the ML)

Building alsa with kernel 2.6 when O= option used.

[Eliot Blennerhassett]

Hi,

should I be able to build alsa 1.0.5 if I have built the kernel as follows?
#cd /usr/src/linux
#make O=~/build/mykernel

ALSA make fails like this
>make -C /lib/modules/2.6.3-13mdk/build
>SUBDIRS=/home/eliot/src/alsa-1.0.5/alsa-driver-1.0.5a/kbuild modules
>make[1]: Entering directory `/usr/src/linux-2.6.3-13mdk'
>Makefile:395: .config: No such file or directory

How do I tell the alsa build process where my kernel config files are?

I tried --with-kernel=dir, but that is for the sources.
Its only the .config , version.h etc that is in a separate directory
