[Q] Problems installing OSS on a slink machine running on 2.1.127
[Sending to debian-devel because this might a developer issue]
Hi,
I have a licensed copy of OSS. I was happily running it with kernel
2.0.35 I recently upgraded to kernel 2.1.127. I downloaded the version
of OSS (http://www.opensound.com/) for 2.1.127 and am having problems
while installing. Here are the various things I tried -
I. Downloaded kernel 2.1.127 from http://www.kernel.org/. Compiled a
custom kernel with make-kpkg. Installed kernel and rebooted.
II. Downloaded OSS (osslinux391a-2035.tar.gz) for Linux 2.1.127 (UP).
III. Extraced the binaries and started running ./oss-install. Chose to
install under /usr/local/lib/oss
IV. Install fails while trying to recompile sndshield with the following
message -
*** 'sndshield' version error ***
You should get new version of the sndshield module
See /usr/local/lib/oss/Readme for more info.
V. /usr/local/lib/oss/Readme says -
The kernel image shipped with many Debian releases differs from the
standard
kernels. For this reason OSS will need the sndshield module to be
rebuilt
in your system. Unfortunately this may fail because the directory
structure
of Debian differes from all other Linux distributions. See notes about
"Solving "sndshield" version incompatibilities" later in this document
for
more details.
....
Solving "sndshield" version incompatibilities
---------------------------------------------
sndshield is a kernel version dependent module which hides minor changes
between Linux kernel versions. It's even possible that some patches or
(rare) kernel config changes break compatibility even the kernel version
number doesn't change. For example the standard OSS/Linux package is not
compatible with kernels configure for SMP (for this reason we distribute
a special SMP version of OSS/Linux for the latest "production" kernel).
So messages about kernel 2.0.30 being incompatible with OSS compiled
2.0.30
are not impossible.
OSS uses a special sndshield module to isolate most kernel version
sensitive
functions from other driver modules. Sources of sndshield are
distributed
with OSS/Linux so it would be possible to fix the compatibility by
recompiling
this module. Precompiled sndshield modules for various systems are
included
OSS and the installation program picks the suitable one (provided that
it's
available).
When OSS/Linux is installed it verifies compatibility between kernel and
the driver by trying to load all driver modules. If any of the modules
fails
to load it attempts to recompile sndshield. However compiling sndshield
will
succeed only if some criterias are met:
1) The kernel sources should be installed on the system. Preferably in
/usr/src/linux.
2) The kernel should have been configured with support for modules
and module versioning (Set version information on all symbols for
modules)
enabled.
3) The kernel include file directories should be symbolic links pointing
to the
active kernel sources in /usr/src/linux. This is not set up correctly by
default in Debian Linux systems.
As the last resort you can install the "official" kernel sources from
ftp.kernel.org and recompile the kernel. After that just try to install
OSS
again.
VI. After reading the above I made a kernel-source package for 2.1.127
and installed it.
VII. cd /usr/src; ln -s kernel-source-2.1.127 linux
VIII. I still keep getting the same problem trying to install once
again.
IX. I tried the following one at a time -
cd /usr/include; mv linux linux.bak; ln -s /usr/src/linux/include linux
cd /usr/include; mv linux linux.bak; ln -s
/usr/src/linux/include/asm-i386 linux
cd /usr/include; mv linux linux.bak; ln -s /usr/src/linux linux
and tried installing with each (making sure I reverted back to the old
/usr/include/linux each time after things failed). Same problem once
again.
[And finally to the question]
How can I make sndshield compile OK? My machine is a HP Kayak XU which
has a AD 1816 sound card.
