Patch for 4.2.2008 for 3.12

[L29Ah]

https://raw.github.com/l29ah/booboo/mas ... 3.12.patch

[nuc]

Is a patch even needed? OSS works fine for me on kernel 3.12..

[Matti]

Thank you very much for the patch it worked.

I installed yesterday kernel 3.12.1 from Ubuntu Mainline Kernel PPA and today I couldn't get OSS to work so I applied your patch to /usr/lib/oss/build/osscore.c and then the modules build successfully.

NOTE: I'm using OSSv4.2 builded from git repository and the last commit that I had in my version was "[bddf15] Added alternative directory for soundon.user under Linux".

[keantoken]

I compiled the Git repository version and it says

Code: Select all

Build ID will be 2006

Why does it seem the Git version is two years late, whereas the latest binaries are 2008? The source archives respond with a build ID 2008.

I tried to use this patch on my 2008 build I already had installed and it only got past osscore, then failed to compile the drivers.

I compiled the Git version and that got past the drivers as well, but then I got this:

Code: Select all

ERROR: could not insert 'osscore': Invalid argument
Loading the osscore module failed
make: *** [install] Error 60

And this:

Code: Select all

$ ossxmix
/dev/mixer: No such file or directory
$ soundon
bash: soundon: command not found

Do you have a sort of Ubuntu?
If it is so difficult for you, you may try Gentoo or other sort of "easy Linux".

No, I'm using Debian. I moved away from Ubuntu a long time ago and even had to get rid of LMDE.

It was an experiment with telepathy _https://en.wikipedia.org/wiki/Telepathy
Sometimes it works, sometimes it does not.
Since you do not explain why and how you are doing something, one has to read your thoughts. It does not always work. Perhaps, I need some training on Ubuntu forum.

What compiler are you using to build osscore?
If gcc-4.8 try using an earlier version gcc-4.7 or gcc-4.6 to check whether the outcome is any different.

[keantoken]

How do I change the compiler? If OSS used a make script this would be easy, but I can't figure out how to get it to build with an older GCC version.

"gcc" is a "symbolic link":

That sure explains a lot!

Well, it didn't work when I compiled with GCC 4.7 or 4.8. I have been using these previously with OSS with no problem.

I'm having trouble with getting OSS4.2 build 2008 going on kernel 3.12.7
I custom built the kernel, it failed to build OSS from OSS 4.2 build 2007
So i downloaded it, ran this patch, followed instructions:
make build
make deb - to make the deb packages

Running 'dpkg -i <compiled deb package>' I get:

Any idea why the build would make just fine but fail the kernel module build?

Thanks for any help!

"gcc" is a "symbolic link":

That sure explains a lot!

Well, it didn't work when I compiled with GCC 4.7 or 4.8. I have been using these previously with OSS with no problem.

Since telepathy often fails, one may need special tools to hack into brains of Ubuntu/Debian users remotely.

They are several symlinks to hack:

Code: Select all

$ ls -la /usr/bin | grep gcc-4.7
lrwxrwxrwx  1 root   root           7 Mar 12  2013 gcc -> gcc-4.7

I'm on Ubuntu 14.04 (development branch) now and so far OSSv4 worked with every kernel in this release (there were 3.12 and now they are 3.13). The default GCC is 4.8 and this also worked but maybe it's a little bit different than the one in Debian.

I make my own packages of OSSv4 using the guide from Ubuntu Wiki but a little bit modified.

Code: Select all

sudo apt-get install -y git
cd /usr/src
sudo git clone git://git.code.sf.net/p/opensound/git opensound-git

Now you should apply the patch

Code: Select all

cd /usr/src/opensound-git/
sudo patch -p1 < oss-4.2.2008-linux-3.12.patch


OSS needs an empty directory to build in. Using the example below will create a directory in your /home folder (~)

Code: Select all

cd ~/
sudo rm -rf oss42build
mkdir oss42build
cd oss42build/

Build & Install

Code: Select all

NO_WARNING_CHECKS=yes /usr/src/opensound-git/configure --enable-libsalsa=NO
make
sudo make deb
sudo dpkg -i oss*.deb

It's also worth to change a setting in configure file before making the OSSv4 package.

Code: Select all

# Set GRC3 min/max conversion quality setting to 3 to conserve space.
# TODO: Add support for configurable quality settings.
GRC_MIN_QUALITY=3
GRC_MAX_QUALITY=6
export GRC_MIN_QUALITY GRC_MAX_QUALITY

This will allow for setting Production quality in ossxmix.
