Arch Linux User Repository

To summarize, how to build on the 5.5 kernel, but not on the 5.4 kernel or earlier:

1) mkdir and cd to a custom build directory.

2) Manually download the PKGBUILD and the two patch files, and rename the PKKBUILD:
https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=evdi-git
https://crazy.dev.frugalware.org/evdi-all-in-one-fixes.patch
https://gitweb.frugalware.org/frugalware-current/raw/master/source/lib-extra/evdi/kernel-5.5-test.patch

3) Edit the evdi-all-in-one-fixes.patch and delete the whole first diff, for travis.yml.

4) Edit the PKGBUILD -

A) comment-out the following lines, as these files do not exist:
install=${pkgname}.install and
changelog="${pkgname}.Changelog"

B) Add the line, under "source=(":
'https://gitweb.frugalware.org/frugalware-current/raw/master/source/lib-extra/evdi/kernel-5.5-test.patch')

C) Delete the trailing right-parenthesis after the line "#'relro.patch'". The parser fails with the intervening comment, and no, that is not a trailing forward-slash, as was mistakenly stated in an earlier comment.

D) Modify the Integrity checks for the modified source line:
md5sums=('SKIP'
'SKIP'
'SKIP')
sha256sums=('SKIP'
'SKIP'
'SKIP')

5) Finally, try building with:
makepkg -Csi

I can also confirm breakage on kernel 4.19.101-1-lts, as well as properly building by removing the .travis portion of evdi-all-in-one-fixes.patch.

Update: With latest kernel (5.5), this build is broken.

Add this patch: https://gitweb.frugalware.org/frugalware-current/raw/master/source/lib-extra/evdi/kernel-5.5-test.patch

And modify the evdi-all-in-one-fixes.patch to exclude the .travis file (it is irrelevant to the build, but breaks the patching process currently).

makepkg is failing because of that trailing / in the git+https URI (L24 of PKGBUILD) to the official vcs

depends=linux-headers doesn't work. All it guarantees is that you have headers for the latest linux, not the headers for whatever linux is booted. My linux-lts packages are fixed to provide=linux-headers but some do not.

For anyone still looking for an answer to @noraj and @bungeye's problem below, the solution is to install the linux-headers package. This should be added to the PKGBUILD as a dependency to prevent other people from having this issue in the future.

just a bump for @noraj's issue to see if anyone has a fix. Just installed Arch and trying to get this set up. I'm having the exact same error. Apologies if this is a rookie mistake.

Anyone have a fix for @noraj's issue below? I'm still experiencing it nigh a month later.

Edit: As of 4 hours ago the dev's said they'd fix the issue and will push soon

1.5.1.r0.gc7e80bc-1 is not building with my 4.19.8 and 4.20.0 kernel, I'm having this error:
