The alsa-drivers INSTALL file tells me:
On 2.6 kernels, the build directory has to be given via --with-build=<kernel_build_dir> option additionaly, too.
What exactly is mean by kernel_build_dir? I should not have to recompile my kernel because I already have the sourcecore module.
It's usually the directory /lib/modules/$VERSION/build points. --with-kernel is the directory /lib/modules/$VERSION/source points. In most cases they are same, but they can be different.
Configure seems to work fine and locates my kernel source code:
./configure --with-cards=hda-intel --with-sequencer=yes
But when I compile, it fails in acore/pcm_native.c line #75, acore/pcm_native.c line #75 uses the macro DEFINE_RWLOCK which apparently has not been defined yet.
Searching thu the alsa-drivers source, I find that include/adriver.h defines this macro.
What am I doing wrong? Why doesn't adriver.h get included when I compile acore/pcm_native.c?
I'm using the latest release - alsa-driver-1.0.14rc4
My Kernel sources are: 2.6.9-34.EL-smp-i686
Maybe it's the problem. It's a modified kernel, and many pieces are backported (even sometimes wrongly). We don't guarantee that the driver would work with any modified kernels.
Check whether DEFINE_SPINLOCK is defined in the kernel header file, and wheter it lacks DEFINE_RWLOCK. If so, the fix would be easy. Add DEFINE_RWLOCK under #ifndef DEFINE_RWLOCK in adriver.h.
