I am not able to make dkms builds for netmap.

I get this error -

Kernel preparation unnecessary for this kernel.  Skipping...

Building module:
cleaning build area...
'make' kernelver=4.12.14-lp151.28.32-default....
Error!  Build of netmap.ko failed for: 4.12.14-lp151.28.32-default (x86_64)
Consult the make.log in the build directory
/var/lib/dkms/netmap/0.0.1/build/ for more information.

According to the make.log build however is complete -

The dkms.conf is here

# netmap dkms
PACKAGE_NAME=netmap
PACKAGE_VERSION=0.0.1
REMAKE_INITRD=yes
AUTOINSTALL=yes
 
# netmap driver
MAKE[0]="'make' kernelver=$kernelver"
BUILT_MODULE_NAME[0]=netmap
DEST_MODULE_LOCATION[0]=/kernel/net/netmap/

When I used to use self-compiled dkms from Dell/DKMS things used to work out, I am not sure why this is so messed up. Please help.

It does not look like kernel module was built at all. You should be seeing CC lines when something is compiled.

Manual install works -

The issue is with autoinstall. I’ve tried 3 different kernels.

This issue is fixed with a proper dkms.conf, the one provided with the source was not sufficient.
