plustek: Thread: pt_drv doesnt' build any more

Hi,
I have just upgraded my Suse 9.1 kernel (due to the known security issue). 
Current kernel version is 2.6.5-7.75 (Suse versioning).

After upgrading the kernel, I have downloaded the latest snapshot of 
sane-backends (sane-backends-2004-06-22.tar.gz). I used the script 
MakeModule.sh to build the pt_drv module. The build completes with one 
warning :

WARNING: Symbol version 
dump /usr/src/linux-2.6.5-7.75-obj/i386/smp/Module.symvers is  missing, 
modules will have CONFIG
_MODVERSIONS disabled

The resulting module refuses to load:

FATAL: Error inserting pt_drv 
(/lib/modules/2.6.5-7.75-smp/kernel/drivers/parport/pt_drv.ko): Unknown 
symbol in module,
or unknown parameter (see dmesg)


The output of dmesg is:
pt_drv: unsupported module, tainting kernel.
pt_drv: Unknown symbol __floatdidf
pt_drv: Unknown symbol __gtdf2
pt_drv: Unknown symbol __floatsidf
pt_drv: Unknown symbol __ltdf2
pt_drv: Unknown symbol __fixunsdfsi
pt_drv: Unknown symbol __adddf3
pt_drv: Unknown symbol __fixdfsi
pt_drv: Unknown symbol __divdf3
pt_drv: Unknown symbol __muldf3
pt_drv: Unknown symbol __nedf2
pt_drv: Unknown symbol __fixdfdi
pt_drv: Unknown symbol __subdf3


====================================
Any suggestions ?

Hmmm,

I've seen one similar problem in another report, but only regarding the
versioning...
The unknown symbol stuff is new - but I'm pretty sure that there is
something wrong with the kernel configuration.
Just to be sure: Have you built the kernel on your own?
If not, then you should probably do this - to make sure, that the
configuration is okay - the missing symbols are quite strange, as
I think your kernel should have floating point support - are you sure,
that the kernel + it's configured source are installed correctly?

Ciao, 
  Gerhard

One thing I've forgotten:

On SuSE you should rebuild your kernel:

cd /usr/src/linux 
 make cloneconfig 
 make bzImage 
 make modules 

This should help...

Hi,

Just did as suggested, results in the same behaviour. I am using
sane-backends-2004-06-23.tar.gz and linux-2.6.5-7.75 (new SuSE9.1 kernel)

# modprobe pt_drv
FATAL: Error inserting pt_drv

Hi Gerhard,
I did this _BEFORE_ trying to build the pt_drv (I always do it after 
installing new kernels). This time, it doesn't help. I have added a package 
kernel-syms-2.6.5-7.75 (previously not installed). It changes behaviour a 
bit. Now I get specific warning about missing symbols at compile time:

and the module (obviously) stlii doesn't load.



These symbols are _really_ not present in the kernel (stock Suse, or rebuilt).

Hmmm, 
I'm somewhat confused...
There's another thing I've found:
cd /usr/src/linux
make prepare-all

Can you guys try this on your boxes?

@Arthur: I know, that this is the general way to install
a kernel - sorry!

I've currently installed 2.6.5-7.82 from SuSE and it seems,
that I can trigger the problem too - I'll keep you informed...

Ciao,
  Gerhard

Tried it. No change.
A.

Okay, I did some more tests, using pristine kernel 2.6.6 works...
No real solution, but I will try and do some more investigations...

Hi,

at least, it seems, that something regarding the floating point support
is broken on that SuSE 2.6.5 Updatekernel.
When you edit the Makefile.kernel26 in the doc/plustek driectory
and simply append the 
-mhard-float
Option to the line EXTRA_CFLAGS @ line 18, then the module will
be built and installed...

Ciao,
  Gerhard

Hi Gerhard.


Your fix is working !
(again!)

Thanks!

Arthur
