2.6.19rc1: pcm_native.c doesn't build

[Elimar Riesebieter]

Hi all,

I tried to build alsa-driver (sources) 1.0.13 against kernel
2.6.19rc1 on i386. The build stops with:

/usr/bin/make -C /usr/src/linux-2.6.19-rc1 \
SUBDIRS=/usr/src/modules/alsa-driver O=/usr/src/linux-2.6.19-rc1 \
CPP="gcc-4.1 -E" CC="gcc-4.1" modules
make[4]: Entering directory `/usr/src/linux-2.6.19-rc1'
  CC [M]  /usr/src/modules/alsa-driver/acore/pcm_native.o
/usr/src/modules/alsa-driver/acore/pcm_native.c:3569: error: unknown field \
'writev' specified in initializer
/usr/src/modules/alsa-driver/acore/pcm_native.c:3569: warning: \
initialization from incompatible pointer type
/usr/src/modules/alsa-driver/acore/pcm_native.c:3589: error: unknown field \
'readv' specified in initializer
/usr/src/modules/alsa-driver/acore/pcm_native.c:3589: warning: \

Any hints?

Is 2.6.19rc1 newer than ALSA 1.0.13?  Building old ALSA against a new
kernel is not supported.

Well, the default imclude/sound/version.h tells:

/* include/version.h.  Generated by configure.  */
#define CONFIG_SND_VERSION "1.0.12rc1"
#define CONFIG_SND_DATE " (Thu Jun 22 13:55:50 2006 UTC)"

IMHO ALSA 1.0.13 should build with kernel 2.6.19rc1.

That's somehow bogus.  We didn't create a patch to increase the ALSA
version number.

No.  It doesn't (can't).  2.6.19rc1 was out after ALSA 1.0.13.
There is no way to support the newer kernel without a magic crystall 
ball to fix everything automatically for the future API breakage :)

It's already fixed in HG version, BTW.
