It looks like the version in the PKGBUILD is wrong. When installing, version 1.7.0.r0.gdc595db-1 is installed, not 1.7.0.r71.gdc595db-1

EDIT: upstream has already LIBVER := 1.7.0 in library/Makefile. Let's use that file for pkgver()

 # Update with > updpkgsums

Make both packages with % makepkg and install with # pacman -U <package> as root

If the dkms automatism fails because of previously broken stuff, try to build/install manually

# dkms status
(look for evdi, add if needed and finally install:)
# dkms install evdi/1.7.0

@bnavigator can you explain what you did to install the latest release?

Works for me:

Linux 5.6.11-arch1-1 x86_64
Name                     : evdi-git
Version                  : 1.6.4.r71.gdc595db-1
Name                     : displaylink
Version                  : 5.3.1.34-1

(I patched the pkgver() function to use the latest tag 1.6.4 instead of the last reachable tag 1.6.2, otherwise it is the same package)

Current version successfully builds but does not work with latest kernel 5.6

uname -srm && pacman -Qi evdi-git | grep -E 'Version|Name' | grep -Ev 'Description' && pacman -Qi displaylink | grep -E 'Version|Name' && sudo lsmod | grep evdi

@brody, I'm not the maintainer but I'm not sure that adding linux-headers to makedepends will work for those using non-standard kernel packages.

Please add 'linux-headers' to makedepends. Then the package is buildable within a clean chroot environment.

Kind regards

This broke the PKGBUILD script triggering the error check in line 74. Add "rm libevdi.so" below line 69 as quickfix.

Looks like the following commit should resolve the 5.5 issue:

https://github.com/DisplayLink/evdi/commit/4722ad8cb55da60e3e1c000284fc0ecaffa17065

I was able to compile it by removing all the patches from PKGBUILD and using the main git tree.
