unofficial linux-ck repo with cpu optimized packages is ONLINE

Ah, I built with gcc without errors. Thanks for reporting.

graysky · 2022-04-14 16:00:06

@JacBoTe - Please try again with 5.17.3-2 ... replacement PKGBUILD is on repo-ck http://repo-ck.com/testing/

with gcc its warning

but I want to use clang for compilation

~~Maybe this is upstream and not coming from -ck patchset. Have you tried linux package with clang to see if you can reproduce it?~~
EDIT: I see it's from the patches - ignore me.

@inglor - did you get that error building 5.17.3-2 which I uploaded a few min ago?

No, I was replied on the previous msg. I haven't tried building it as I'm not sure how to build with clang

inglor · 2022-04-14 16:45:43

@graysky: the testing repo has the PKGBUILD and config but not all source files. Where do we find those if one wants to compile it?

graysky · 2022-04-14 17:42:50

My bad, they are present now.

graysky · 2022-04-14 18:27:18

FYI - can you build with clang using this PKGBUILD. I did not edit it to work with modprobed-db, just the full set.

JacBoTe · 2022-04-15 02:08:22

@graysky - Compiled successfully with clang

@graysky when building with clang the 5.17.3-3 (7adddf4380beaa07703f26d3c99950d078e9e75f) in clean chroot it fails due to missing makedepends:

Thanks, fixed in 5.17.3-4 just now.

inglor · 2022-04-15 11:47:13

A bit out of subject here but what is the real benefit of using clang instead of gcc?

brikler · 2022-05-31 08:21:06

hi

a question: does "clang" honor in the PKGBUILD selected cpu? because "clang" supports LTO for the kernel…

graysky · 2022-05-31 09:52:07

It should.

brikler · 2022-05-31 12:09:08

thank you for this really quick answer
