gcc march
 
Hello,
Using suse 8.2 i am trying to develop a driver for a card (plx 9030 chip).
I am running an athlon 2400.

When i try to load the driver using insmod this happens:

kernel-module version mismatch
driver.o was compiled for kernel version 2.4.20-4GB while this kernel is version
2.4.20.GB-athlon.

I have set march=athlon.
And inlude files to /lib/modules/2.4.20-4GB-athlon/build/include

Any ideas?
I am a hardware developer gone mad......:-)

Did you compile the kernel 2 times or maybe you set the wrong EXTRAVERSION parameter in Makefile from kernel source tree.

agdepus 05-24-2004 01:05 PM

I did not compile the kernel at all. Do I have to do that in order to
build an installable module??? :-)

keefaz 05-24-2004 02:08 PM

No lol, I asked this because the difference between kernel names.
And what output does the uname -r give ?

agdepus 05-25-2004 03:11 AM

2.4.20-4GB-athlon.....

keefaz 05-25-2004 07:45 AM

Does the error happen if you don't set the -march parameter ?

And do you have these lines in your source code :
Code:

/* Deal with CONFIG_MODVERSIONS */
#if CONFIG_MODVERSIONS==1
#define MODVERSIONS
#include <linux/modversions.h>
#endif

I included the output from gcc below. Including the modversions did not fix it....
My problem is that i know too little about this stufffff...

I'll never give up...:-)

Linking driver: Pci9030.o


Device driver "Pci9030/Driver/Pci9030.o" built sucessfully.

Maybe a tip :

edit /lib/modules/2.4.20-4GB-athlon/build/include/linux/version.h

Look at the value for UTS_RELEASE, if it is set it to 2.4.20-4GB-athlon if not set the value

That's it. Thanks :-)
