akvcam module compilation
on kernel-5.18.2-pclos1 compilation works, but a other issue come up:
#modprobe akvcam modprobe: ERROR: could not insert 'akvcam': Exec format error
SOLVED for PCLinuxOS a patch to /src/MAKEFILE was needed to enable rightly working dkms functions on this special distribution
@hipersayanX i use this: link: https://www.qua-it.org/XFCE/shots/share-with-pclos/pclos/akvcam-Makefile-pclos.patch link to patched Makefile: https://www.qua-it.org/XFCE/shots/share-with-pclos/pclos/akvcam-patched-Makefile
have make reply on your git, how can post code in raw there? even i will post a patch the format of strings will breaks ... so i post you the links to patch and resulting patched Makefile Greetings

I have patched Makefile with this patch only on kernel 5.18.3. make => compilation failed (cf: make_5.18.3.log) then compilation with DKMS on not-patched kernel 5.19.0-rc2. same errors (cf: make_5.19.0-rc2.log)
make_5.18.3.log make_5.19.0-rc2.log
here is the dkms.conf from pclos... with it all should works: link: https://www.qua-it.org/XFCE/shots/share-with-pclos/pclos/akvcam-pclos-dkms.conf in raw:

ups, i must do it again, the patch not solving the problem, i have a pre installed version on differ place, now i clean my kernel-tree and all dkms from tree and begin a newer build, if i can check success by install on kernel-5.17.... and then boot in kernel 5.18.3... and the command dkms status and a modprobe akvcam give my not errors, then i post here ....
now it's working build as rpm dkms-akvcam on PCLinuxOS kernel-5.17.15, upload to my repo, then install with: apt-get update ; apt-get install dkms-akvcam no errors during modules build, reboot and : lsmod | grep akvcam akvcam 192512 0 videobuf2_vmalloc 16384 1 akvcam videobuf2_v4l2 36864 1 akvcam videobuf2_common 69632 4 videobuf2_vmalloc,videobuf2_v4l2,akvcam,videobuf2_memops videodev 270336 3 videobuf2_v4l2,videobuf2_common,akvcam
now reboot to kernel-5.18.4 and wait a few minutes, dkms automatical build for this kernel, if ready reboot, and : lsmod | grep akvcam akvcam 192512 0 videobuf2_vmalloc 16384 1 akvcam videobuf2_v4l2 36864 1 akvcam videobuf2_common 69632 4 videobuf2_vmalloc,videobuf2_v4l2,akvcam,videobuf2_memops videodev 270336 3 videobuf2_v4l2,videobuf2_common,akvcam

PCLinuxOS still keep older version but good configured dkms-stuff without systemd's
Hope this will help to compile the modules on other distri's

@ohquait
for me can close
Don't, I must still check what I can take from the patch.

it's OK now for me

it's not working on my Debian/Sid distribution.
What's your gcc version (may be the problem)?
I made compilation with gcc 11.3.0 version
