Re: [Linux-gpib-general] Cannot make linux-gpib-kernel-4.2.0

[Werner K. <wer...@on...>]

Hi Julien,

I received a mail with a hint that fixed my problem. Now I don't know if I can find that mail 
again. I was told that this looks like a particular OpenSuse problem. Here is my query first:  

*******************************************************************
Hi,
 
I followed the installation description in the linux-gpib-kernel-4.2.0 directory until the 
make-command. In the output I get
 
echo >&2;                                                       \ 
echo >&2 "  ERROR: Kernel configuration is invalid.";           \ 
echo >&2 "         include/generated/autoconf.h or include/config/auto.conf are missing.";\ 
echo >&2 "         Run 'make oldconfig && make prepare' on kernel src to fix it.";      \ 
echo >&2 ;                                                      \ 
/bin/false)

and 
 
/home/werner/GPIB/linux-gpib-4.2.0/linux-gpib-kernel-4.2.0/drivers/gpib/lpvo_usb_gpib/
lpvo_usb_gpib.c:621:13: err
or: unknown type name ‘wait_queue_t’; did you mean ‘wait_event’? 
#define WQT wait_queue_t 
            ^
 
I ran "make oldconfig && make prepare" without error, but the errors above remained. I 
looked for the type-description ‘wait_queue_t’ but didn't find anything apart a remark in a 
log-file that didn't help me  ( "include /sys/sysmacros.h for minor() definiton" )
 
My system:  OpenSuse Leap 15.0,  x86_64, 
kernel  4.12.14-lp150.12.48-default
 
Now I don't know how fix that problem. I am not a big expert in Linux.
Do you have any idea, any hint
 
Best regards
Werner
*******************************************************************
Oh yes, Julien,

now I found a note concerning that problem. I simply copy the important part of the note:

*******************************************************************
Hallo Werner,
The first message is not an error message, it is in fact
the echo of the build script commands.
The second is an error which might be specific to Suse.
To fix this please change line 620 in 
drivers/gpib/lpvo_usb_gpib/lpvo_usb_gpib.c
from 
*#if LINUX_VERSION_CODE < KERNEL_VERSION(4,13,0)*
to
*#if LINUX_VERSION_CODE < KERNEL_VERSION(4,12,14)*
mfG,
-Dave
*******************************************************************
Best regards
Werner
