plustek: Thread: SMP module loading errors

Hi people....okokook
I have installed and compiled all the necessary files for my Plustek Optic pro
4831P scanner.

When at the last steps in the directory:

/temp/sane-1.0.2/backend/plustek_driver/make  -f Makefile load it
says:

 /sbin/modprobe pt_drv || exit 1
/lib/modules/2.2.5-22smp/misc/pt_drv.o: kernel module version mismatch
  lib/modules/2.2.5-22smp/misc/pt_drv.o was compiled for kernel version 2.2.5-22
while this kernel is version 2.2.5-22smp
make:*** [load] Error 1



heeeeelllpp
I uncommented the SMP=1 line in Makefile but no luck.
Can anyone help please
Vas

Hi Vasileios,

any success so far?

I've currently tried to load the module on
one of our MP machines (SuSE 6.2 - Kernel 2.2.10smp)
and had no problems.

I cannot figure out why there's a problem...
When you use the SMP switch, then you also should
get the correct version string out of the kernel header
files!

If you have managed to solve the problem, please
let me know.

Hmmm....that might be the problem....the version string.
How do I do that???

Hi,

thought you already had commented out the SMP=1
switch in the makefile!
By uncommenting the switch, a -D__SMP__ will
be added to the CFLAGS and afer recompiling
you should have a driver, that contains the correct
string. Try
strings -a pt_drv.o | grep kernel_version 

and you should receive something like:
kernel_version=2.2.16
__module_kernel_version  

In your case this should be
kernel_version=2.2.5-22smp

You should also check the file /usr/include/linux/version.h.
Theres an entry like
#define UTS_RELEASE ...

and the file  /usr/include/linux/autoconf.h
#define CONFIG_SMP

These files will be modified when configuring
the kernel via make menuconfig...

Check this please.

Ok Ok  I think I managed to solve about 90% of this problem. 
What I did I I copied the contents  (  /2.2.5-22smp)  of the directory
/lib/modules to  the directory /lib/oldmodules. So the /lib/modules is empty. 
Then I recompile my kernel  with parallel port support as a module (make clean;
make dep; make bzImage; make modules, make modules_install)  and the directory
/lib/modules is reconstructed but with its contents as /2.2.5-22.
So when I now type make load for the plustek scanner it all works and the light
turns on. Success....
But then when I type scanimage i get this message:

[root@Lava /root]# scanimage
scanimage: error in loading shared libraries: libsane.so.1: cannot open shared object file: No such file or directory       


What is this library I am missing?
Anyway....I guess if I find this library it should work fine


I hope it helps someone

Hi Vasileios,

it seems, that you first have installed the binary version
of SANE. Then you recompiled the stuff and installed it
to a wrong place. When using SuSE, you should
configure the sane stuff as follows:
(in the sane source directory)
./configue --prefix=/usr --sysconfdir=/etc

Then recompile and reinstall sane. This should solve
your with the libs...

Well all I did really is downloaded the tar.gz files (the sane and the 
plustek) and followed the instructions. Unzipped the sane in a temp and 
unzipped the plustek in the temp as well. Overwritting the /backend. 
Anyway...I haven't installed an rpm (if such a thing exists) and I am sure i 
didn't select a directory when compiling or make install. I just did the 
defaults.

I have RH 6.0 actually. Do the same settings apply?
I think I am getting really close to making my scanner work
Thanks for the help
Vasileios

No!
Have a look at the INSTALL file there's a detailed
description how to find the correct --prefix and --sysconfdir
settings....

 Hi it is me again....ok sorry for being such a pain but this motherf*****
still doesn't work. I compiled everything with the correct  --prefix  and
--sysconfdir  (I have RH 6.0 but I even tried the settings for SuSE) but no
luck.
The same crap about libsane.so.1


Has anyone had the same problem??? 

One thing I do not understand in the INSTALL document. It says :



 "Now find out where a previous installation is placed."
...
...
"We now call the configure script in the sane source directory (depending on"
"the  info we already got (I assume a previous installation at /usr and /etc"
"which is usual for a SuSE distribution, RedHat uses /usr/local and"
"/usr/local/etc)"

 My question is: -What previous installation???? Are we supposed to have some
sane directories allready existent???? Or  does it assume an upgrade.


Thanx for your time
Vas

Hi,

"Try to find a previous installation" means, that if
you have installed a binary version (i.e. during installation
of your system, or so) you have to find the lib 
directory of this installation! You have to do this to make
sure that your newly build libraries were copied into the
same path like the old ones. If you never had installed
a SANE version before, there's no need to use another "prefix"
of "sysconfdir", simply do a "configure".

You might add the library path (/usr/lib/sane) to your /etc/ld.so.conf
file.
