Hi all,
I am trying to create a PKGBUILD for a usb wifi dongle driver with the use of DKMS. But I am apparently having some problems with the dkms configuration.
After installation of my package the output of "dkms status" is:
$ dkms status
rtl8188eu-v4.1.8_9499-dkms-git, 1.0.r653.0b659bd, 4.16.13-2-ARCH, x86_64: installed (WARNING! Diff between built and installed module!)After removal of the package I get:
$ dkms status
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/rtl8188eu-v4.1.8_9499-dkms-git/1.0.r653.0b659bd/source/dkms.conf does not exist.Appearently not everything seem to be removed. How can I solve this?

You want to create a package for just the DKMS half of this split package https://aur.archlinux.org/packages/rtl8188eu-dkms-git/ ?
Why do this for a DKMS package?
build() {
cd "$srcdir/${pkgname}-${pkgver}"
make all
}
package() {
cd "$srcdir/${pkgname}-${pkgver}"
# Install driver
install -Dm644 8188eu.ko "${pkgdir}/usr/lib/modules/${_kver}${_modloc}/8188eu.ko"Offline
Thank you for your response,
In fact I used the rtl8188eu-dkms-git package's PKGBUILD as a template. But this package package uses a different branch of the repository. Next thing is that this package is out of date because it requires an old kernel (4.12) and does some unnecessary actions that are not needed with current version of pacman (running the depmod in an install script).
Now why I do the make all and install - if you look at rtl8188eu-dkms-git's PKGBUILD they do exactly the same. So what is the correct approach to build a DKMS package within a PKGBUILD?
Offline
Drop the build function the split package has the build for package_rtl8188eu-git() to install package_rtl8188eu-dkms-git() does not install the built module as DKMS will build it.
Did you try removing rtl8188eu-dkms-git makedepends on the older kernel and see if it then built?
Offline
Aha, I am sorry I was a little confused with the build() function. Also in the arch wiki https://wiki.archlinux.org/index.php/Dy … le_Support there is an example PKGBUILD which actually runs 'make install' in the package function - is this not needed today?
After making some modifications in the PKGBUILD of rtl8188eu-dkms-git I managed to build it with my prefered branch (see the PKGBUILD below).
However ... do you think there is a reason for dkms module getting installed into '/usr/lib/modules/kernel/drivers/net/wireless/' whereas the non-dkms module getting installed into '/usr/lib/modules/extramodules-4.16-ARCH/' ?
Thank you a lot for your help!
The final working PKGBUILD (using the branch v4.1.8_9499) looks like this:

I think the different install location is because DKMS rebuilds the module on every kernel version change even if the ABI is still compatible.
Modules in extramodules only need rebuilding when there is an ABI change.

Ok thank you for the info, I mark this thread as solved.
