ndiswrapper and kernel source&compile??

Gallan · #1 21st June 2005, 11:57 AM

hello

I have read manymanymany topics and googled but I'm still stuck! I have FC3 with 2.6.11-1.27 kernel and I would like to know do that kernel support 4 or 16 stacks? I have found yes answers and no answers so what is the truth?

I have done this kind of things:

I installed kernel source and ndiswrapper and I had no errors. I found right driver to wlan card and when I type ndiswrapper -l that drivers is ok and hardware also. when I type modprobe ndiswrapper I get FATAL: Error inserting ndiswrapper (/lib/modules/2.6.10-5-686/misc/ndiswrapper.ko) invalid module format. I have tried to figure this out but my skills are limited so I'm stuck! I read ndiswrapper faq and try those steps and it seems to be ok. There is one thing: If I have 1.27 kernel source and in grub I choose kernel 1.27.stk16 can there be something wrong...I'm using different kind of kernel what my source is??is there any idea??

so I know that my problem is some how connected to kernel (maybe) but can someone tell exactly how!!??!!

and If something more is needed please ask!!

dmesg gives:

ndiswrapper: version magic '2.6.11-1.27_FC3 686 REGPARM 4KSTACKS gcc-3.4' should be '2.6.11-1.27_FC3.stk16 686 REGPARM 16KSTACKS gcc-3.4'

It looks like you have the 16K stack kernel binary, but the sources are configured for 4K stacks. You must use the same sources as the binary kernel, unless you want to do some complicated playing with kernel source.

Gallan · #4 21st June 2005, 07:08 PM

ok so I should find kernel sources to stk16 kernel?? do you have idea where?

Gallan · #5 21st June 2005, 08:10 PM

ok I searched but no luck...

I had 2.6.11-1.27_FC3 kernel and I loaded and installed source to that. then I loaded kernel-2.6.11-1.27_FC3.stk16.i686.rpm.zip and unzipped it and ran rpm -Uvh kernel.....

so I have to do something but I have no clue what!!!! HELP

It's on the same page you downloaded the kernel from:

http://www.linuxant.com/driverloader...16.src.rpm.zip

Unzip it, 'rpm -Uvh' it, then (if it does not do it automatically) create a sybolink link from /lib/modules/2.6.11-1.27_FC3.stk16/build to wherever the source got installed (probably /usr/src/kernels/2.6.11-1.27_FC3.stk16)

Then try the ndiswrapper compile again.

Is there any pre-compiled 16K kernel for Fedora Core 4??
The documentation that comes with DriverLoader, says to go to the link with FC4 in it.
Problem is, it doesn't exist.

I did what use said fsck but still when I get modinfo ndiswrapper:

there is that vermagic with 4stacks!!!

Ok, my bad. The source RPM provides the source tgz, a bunch of patches and the spec file. You might try the following, but read this first: "THIS IS UNTESTED, AND MAY BREAK THINGS." but it probably won't, so hey.:

Code:

rpm -Uvh kernel-2.6.11-1.27_FC3.stk16.src.rpm
rpmbuild -bp --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec
vi /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/Makefile
 + change this:
---
EXTRAVERSION = -prep
---
 + to This:
---
EXTRAVERSION = -1.27_FC3.stk16
---
cd  /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/
make include/linux/version.h
make modules
rm /lib/modules/2.6.11-1.27_FC3.stk16/build
ln -s /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/ /lib/modules/2.6.11-1.27_FC3.stk16/build

then rebuild the ndiswrapper stuff from scratch doing

Code:

make distclean 
make all KVERS=kernel-2.6.11-1.27_FC3.stk16 KSRC=/usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11
make install

That gives me:

Code:

[root@songspire ndiswrapper-1.2]# modinfo driver/ndiswrapper.ko filename:       driver/ndiswrapper.ko

Which (ignore the gcc-4.0, I'm on FC-4) should be what you are after, no?

Gallan · #10 25th June 2005, 07:57 PM

hello fsck!

I'm trying that now! we will see what happens! you are using fc4, is there 16 stack kernel or 4? and do you know can I remove or do I have to remove when I have installed kernel source and there comes a new kernel and I wnat to install sources to that kernel? this because I have earlier installed source to 2.6.11-1.27_FC3 so can this 16stack kernel and source mix that up?

fsck · #11 25th June 2005, 08:20 PM

It's all 4K for FC4 at the moment, as I understandit. There is much talk about it on the boards.
As for mixing up kernels, as long as you keep the source in different directories for each kernel revision you'll be fine.
If you choose to upgrade the kernel binary, you'll have to perform the above again with the new kernel source which matches the binary. Unless the fedora maintainers get around to giving us both a 16K stack kernel and source.

Gallan · #12 25th June 2005, 08:40 PM

you ask me to remove /lib/modules/2.6.11-1.27_FC3.stk16/build and now ndiswrapper doesnt find source from there!?!

I didn't know why to remove that file but...?!?!?!?
[
root@theone ndiswrapper-1.2]# make install
make -C driver install
make[1]: Entering directory `/root/ndiswrapper-1.2/driver'
Can't find kernel sources in /lib/modules/2.6.11-1.27_FC3.stk16/build;

make[1]: *** [prereq_check] Error 1
make[1]: Leaving directory `/root/ndiswrapper-1.2/driver'

fsck · #13 25th June 2005, 08:47 PM

I asked you to remove that link, and recreate it with:

Code:

ln -s /lib/modules/2.6.11-1.27_FC3.stk16/build /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/

Which was my mistake, I always get 'ln' commands the wrong way round. Please do:

Code:

rm /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/build
ln -s /usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/ /lib/modules/2.6.11-1.27_FC3.stk16/build

And then do the "make install" again. If this fails, you can probably do

Code:

make install KSRC=/usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11/

I've also corrected in initial post.

Gallan · #14 29th June 2005, 04:12 PM

thanks fsck for your help!! you clearred some things to me! I installed FC4 and now everything is working just fine

fsck · #15 29th June 2005, 04:18 PM

Hurrah! Glad to help.
