-If ./configure command complain that alsa-driver package is not installed,
-please, check if --prefix option is same for alsa-driver and alsa-lib
-package. The configure script from alsa-lib package probably cannot find
-header file asound.h in $prefix/include/sound directory (usually in
-/usr/include/sound directory).
-
-Note: If you change kernel sources frequently, please, check if you have
- compiled and installed alsa-driver for current version of your kernel.

-Installation using a build-in version of ALSA in Linux kernel
--------------------------------------------------------------
-
-If you use a kernel build-in version of ALSA, use:
-
- ./configure --with-kernel=<version>
- make install
-
-The directory /lib/modules/<version>/build/include/sound must exists for
-this kind of configuration.
-
-You may also specify the full-base for ALSA kernel headers:
-
- ./configure --with-soundbase=<path_to_linux_include_dir>
- make install
-
-example:
-
- ./configure --with-soundbase=/usr/src/linux-2.5.5/include
- make install
-
Compilation from CVS sources
----------------------------
i686 host but for arm architecture) you will need to call ./configure
script with aditional parameters:
-CC=arm-linux-gcc ./configure --target=arm-linux \
---with-soundbase=/usr/local/arm/src/linux/include
+CC=arm-linux-gcc ./configure --target=arm-linux
In this example host where the library is build is guessed (should be
given with --host=platform) and target for which is the library build is
-Linux on ARM architecture. You need to specify location of kernel includes
-configured for target architecture. This is used to find ALSA include
-files and so it should be set to prefix where '/sound' directory should
-be found. You should ommit setting 'CC' variable and cross-compiler will
-be guessed too. You could also use option '--prefix' to specify ALSA include
-directory directly if $prefix/include/sound exists.
+Linux on ARM architecture. You should ommit setting 'CC' variable and
+cross-compiler will be guessed too.
So simplest version would be:
-./configure --target=arm-linux --with-soundbase=/usr/local/arm/include
-
-or
-
-./configure --target=arm-linux --prefix=/usr/local/arm
-
-As you will likely specify the prefix, the last posibbility would be
-the best if everything match. On the listing of 'configure' script
-check if directory with ALSA headers was found properly same as platform
-specific configurations like processor type and selected cross-compiler.
+./configure --target=arm-linux
For platform names in the form cpu-vendor-os (or aliases for this)
you should look in 'config.guess' script. Target and all paths
