generate backport error

generate backport error

[Shetu Ayalew]

Hi,

I'm trying to run the the gentree.py.
I use coccinelle 1.0.7 and the following tree - 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/

with few different tags the last one was v5.7-rc3-1 (for backports 
tree)  and v5.7-rc3 (for the Linux tree).

and I get error:

Traceback (most recent call last):
   File "./gentree.py", line 1107, in <module>
     ret = _main()
   File "./gentree.py", line 724, in _main
     logwrite=logwrite)
   File "./gentree.py", line 914, in process
     kver = gen_version.kernelversion(bpid.project_dir)
   File 
"/.autodirect/swgwork/shetu/upstream/backports/lib/bpversion.py", line 
40, in kernelversion
     _check(process)
   File 
"/.autodirect/swgwork/shetu/upstream/backports/lib/bpversion.py", line 
11, in _check
     raise ExecutionError(process.returncode)
lib.bpversion.ExecutionError


To my understanding the source of the above error is the fail of the run 
of the following command that the script executes:

"make --no-print-directory -C  /swgwork/shetu/upstream/backport_vr 
kernelversion"

The error I get is "you shouldn't run make in the backports tree, but 
only in the generated output ...".

But the directory backport_vr is not under the backports tree. Moreover 
I tried running make kernelversion

from backport_vr and I got the same error message. Do you familiar with 
this probelm, any idea how to solve it ?


Thanks,

Shetu.

Hi Shetu,

The script tries to get the kernel version of the kernel you want to
create a backports release for and this somehow fails.

Could you please run this manually like I did here:

$ make --no-print-directory -C ~/linux/linux-next kernelversion
5.7.0-rc3
$ echo $?
0

Please keep the mailing list in CC.

Hi,

I did  and got the same output as you. But it seems like the script is 
not using the source tree path as in you asked me to do, rather it uses 
the output tree (after backport) path.
Looking into the Makefile is looks like the it checks if file named 
local-symbols exits (which not) and thus fails.

Thanks

Shetu.

How do you call the ./gentree.py  script like this?
./gentree.py ~/linux/linux-next-clean/
/home/hauke/backports/backports-5.7-rc3-test1

If you just need the wifi drivers form a recent kernel you can also
download a pregenerted tar here:
