Instead of deleting folders, may also edit [folder]/config to add the missing .git to the end of the url.

Also kind reminder that now that now that the sources have a .git you have to delete your AUR helper cache so it doesnt yell about it not being a clone bla bla

Pushed a commit that makes the commit hash part of the version always be 9 characters long, i decided with 9 as it already was the length used, just for consistency

It's not specific to an AUR helper, but how the user configured their git. It just make sure that the version generated is consistent for all users regardless of their configuration.

In this case, on my system, the version generated is r3529.bef1567a-1 while this package is r3529.bef1567a6-1 in the AUR. For aur helpers, it think that r3529.bef1567a6-1 is more recent.

@patlefort What specific aur helper has problems with this package?

patlefort commented on 2023-12-26 06:56 (UTC)

Can you please change git rev-parse --short to git rev-parse --short=7 as prescribed in the wiki? The version generated in this pkgbuild has more chars than the default and will lead to aur helpers thinking that there is always or never an update.

the "avx2 optimization no" is an echo from qemu's configure script, a dependency of unicorn

With -march=x86-64-v3 -O3, the following is displayed during initial config. What is the criteria for displaying yes/no?

avx2 optimization no

Build completes successfully without the SSE2 warning / "error".

XXH3 Fixed in the last push, now XXH_X86DISPATCH_ALLOW_AVX gets enabled with a cmake option

xiota commented on 2023-11-10 01:08 (UTC)

Error: if _____ is compiled with AVX enabled, the resulting binary will crash on sse2-only cpus !!

Stating the obvious.

I added -march=x86-64-v3 -O3 -mavx -mavx2 -mfma -DXXH_X86DISPATCH_ALLOW_AVX=ON to CFLAGS and CXXFLAGS. No complaints during build, but config still says:

avx2 optimization no

patlefort commented on 2023-11-10 00:02 (UTC)

It currently won't compile if AVX is enabled: 

/pkgbuild/vita3k-git/src/vita3k/external/xxHash/xxh_x86dispatch.c:93:4: error: "Error: if xxh_x86dispatch.c is compiled with AVX enabled, the resulting binary will crash on sse2-only cpus !! "          "If you nonetheless want to do that, please enable the XXH_X86DISPATCH_ALLOW_AVX build variable"
#  error "Error: if xxh_x86dispatch.c is compiled with AVX enabled, the resulting binary will crash on sse2-only cpus !! " \
   ^

Their cmake file doesn't allow setting XXH_X86DISPATCH_ALLOW_AVX but a little sed magic can do the trick:
