temporary fix for ndiswrapper on linux 3.3 on i686

Hi,
You may have noticed that there is no package of ndiswrapper for linux 3.3 yet. The maintainer is working on it.

So in the mean time, you can to do it yourself. Here is how I have done it:
Use this patch to ndiwrapper sources (found on ndiswrapper bugtracker):

you need to modify ndiswrapper.install to use EXTRAMODULES='extramodules-3.3-ARCH'

One extra step is needed for i686 users. One need to patch the linux kernel headers that seems to have a bug to allow ndiwrapper to compile
So you can make your own package with the patch, or simply patch it on your system. That's the "hack" I used

Re: temporary fix for ndiswrapper on linux 3.3 on i686

Now that linux-headers is updated to version 3.3.2-1. Do I still need to use that header patch? Also any news from maintainer about official ndiswrapper-package for i686 architecture, seems that x86_64 users already got their updated package.

Re: temporary fix for ndiswrapper on linux 3.3 on i686

You could see I have updated the patch to work against linux-headers-3.3.2-1. May be, I should have advertized it.

The maintainer has updated the x86_64 package and must have talked with the maintainer of linux-headers package to include the patch. I guess he has refused to do so ? I had no news from the maintainer after the initial contact, reply phase. I email him right now.

I am surprise this does not cause much more attention or reaction. noone is using ndiswrapper ? or is it i686 + ndiswrapper that is rarre nowadays ?

Re: temporary fix for ndiswrapper on linux 3.3 on i686

Hi,
I am a beginner in Arch and I have problems. This are the things I did:

1. Downloaded ndiswrapper 1.57 source from sourceforge.

2. Extracted this .tar.gz archive into my home folder.

3. Saved first patch from the topic to file ndis.patch in ndiswrapper source folder.

4. Run terminal and executed:

   cd ~/ndiswrapper-1.57/
   patch -p0 <ndis.patch

   Two files were sucesfully patched.

5. Executed:

   sudo make uninstall

   and here I've got a problem:

   rm -f /usr/share/man/man8/ndiswrapper.8
   rm -f /usr/share/man/man8/loadndisdriver.8
   make -C driver uninstall
   make[1]: Entering directory `/home/vas/ndiswrapper-1.57/driver'
   Makefile:36: *** Cannot find kernel version in /lib/modules/3.3.2-1-ARCH/build, is it configured?.  Stop.
   make[1]: Leaving directory `/home/vas/ndiswrapper-1.57/driver'
   make: *** [uninstall] Error 2

Solved by installing ndiswrapper from community repo.

same error on my PentiumIV! i think there has yet been opened a bug https://bugs.archlinux.org/task/29493, but nobody cares! I hope the mantainer will do something ...

There is already a new ndiswrapper on a testing repos http://www.archlinux.org/packages/commu … iswrapper/, and I think it should fix these problems. Now you have to just wait it to come to the community repos.

Re: temporary fix for ndiswrapper on linux 3.3 on i686

@vas: you should look at how to make package on archlinux, using PKGBUILD, makepkg and AUR.
Look in the wiki for any help: https://wiki.archlinux.org
