I have now refined the description of the original problem, after theother problems were resolved. The init_utsname problem only occurs withthe RHE5.1 kernel, and not with the corresponding vanilla kernel.orgkernel.
My build procedure is (this is before Jaroslav fixed the alsa-kmirrorissue):
$ git clone git://git.alsa-project.org/alsa-kmirror.git alsa-kmirror$ git clone git://git.alsa-project.org/alsa-driver.git alsa-driver $ cd alsa-driver$ ALSAKERNELDIR=../alsa-kmirror ./gitcompile
The Linux headers in /usr/include/linux are owned by the packagelinux-headers-2.6.8-53.1.19 from RHEL5.1 .
Note the resultchecking for init_utsname... noHowever, this kernel includes a definition for init_utsname ininclude/linux/utsname.h:37:52. The configure test has detected the wrongresult.
Further down, the build fails
CC [M] /home/stanb/Desktop/Drivers/alsa-driver/acore/info_oss.oIn file includedfrom /home/stanb/Desktop/Drivers/alsa-driver/acore/../alsa-kernel/core/info_oss.c:29,

If I build against a kernel.org vanilla 2.6.18, as follows:
$ cd linux-2.6.18$ make modules_prepare$ cd ..$ git clone git://git.alsa-project.org/alsa-kmirror.git alsa-kmirror$ git clone git://git.alsa-project.org/alsa-driver.git alsa-driver $ cd alsa-driver$ ALSAKERNELDIR=../alsa-kmirror ./gitcompile--with-kernel=../linux-2.6.18 --with-build=../linux-2.6.18
Then the build fails further down (for a different reason):
