Error Compiling Driver code:

[jalaja devi]

Hi ,
I am trying to compile a driver code in Red Hat 6.2
which is already a working code, but I get the
following errors when i compile. 

/usr/src/linux/include/asm/smp.h:206: arguments given
to macro `hard_smp_processor_id'

Any clue or hint will be helpful.

Thanks
jalaja

smp errors in 2.4!!

[jalaja devi]

I encounter this compilation error:
/usr/x.c:2112: struct has no member named
"event_Rsmp_7b16c344"

The structure has that field and I don't have the
conflicting structure name anywhere in my code and in
the system files too. 

The makefile uses sed and *.d files.

Could anyone help me out as how to fix this.

Thanks
Jalaja

Re: kernel2.2.x to kernel2.4.x

[jalaja devi]

How can I handle this from kernel2.2 to kernel2.4

Can I replace like this??

if (test_and_set_bit (0, (void *)&dev->tbusy)){ return
EBUSY;} ========== with  netif_stop_queue (dev);

clear_bit ((void *)&dev->tbusy); ===== with
netif_start_queue(dev);

Thanks
Jalaja

	Has not gone away, your includes are wrong

You need to "unroll" copy_to_user_ret().  There is no
corresponding macro.  Just test the condition and return
-EFAULT (?; not looking at the source code) if it's invalid.

Don't know about "outs".

__bad_udelay means that some module used a too-large-parameter-value
to udelay().  Linker should be telling you which module.

kernel2.2.x to kernel2.4.x

[jalaja devi]

I tried porting a network driver from kernel2.2.x to
2.4. When i tried loading the driver, it shows the
unresolved symbols for
copy_to_user_ret
outs
__bad_udelay

Could anyone please tell me the corresponding fxns in
2.4.

Thanks in advance
Jalaja
