I declared MAKEFLAGS="--jobs=$(nproc)" in /etc/makepkg.conf per https://wiki.archlinux.org/title/Makepkg#Parallel_compilation

ninja takes -jN syntax, not --jobs=N.

I propose this patch to PKGBUILD:

diff --git a/PKGBUILD b/PKGBUILD
index 219ac59..af4af72 100644
--- a/PKGBUILD
+++ b/PKGBUILD

+    MAKEFLAGS=$(echo "$MAKEFLAGS" | sed -E 's/--jobs=([0-9]+)/-j\1/g')
     ninja -C build ${MAKEFLAGS:--j1}
 }

New version, several cleanups and missing dependencies. Please apply: https://0x0.st/82Qa.mbox

Recent dlib update leads to missing dependency: /usr/lib/photoview/photoview: error while loading shared libraries: libdlib.so.19.23.0: cannot open shared object file: No such file or directory

I tried to reinstall it, but the build failed:

============= Failed to compile.

You must provide the URL of lib/mappings.wasm by calling SourceMapConsumer.initialize({ 'lib/mappings.wasm': ... }) before using SourceMapConsumer
 I don't know if the warning is relevant, the full output is quite long and I don't see what else is relevant.

seems dlib.net timeouts or has an invalid certificate

maybe fetching the tarball from github would be more reliable ?

Maintaining two packages for different variant of same package is rather suboptimal. But as you refrain form using config vars in the PKGBUILD, perhaps you would like implement detection ofavx2 extension of the host cpu and enable the USE_AVX_INSTRUCTIONS cmake flag base on that?

Check appleseed PKGBUILD for reference: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=appleseed#n70

!btw. I've to gave some thought to my appleseed PKGBUILD as user may cross build for different machine and would want a direct control over the CPU optimization flags...

@xantares, I don't have the rights to do that... but I can set it up in the following days :)

xantares commented on 2021-01-17 11:01 (UTC)

can you add me to the package maintainers, I'll try to set up the ENABLE_CUDA var

xantares commented on 2021-01-08 17:40 (UTC)

that would be cool

bartus commented on 2021-01-07 11:33 (UTC) (edited on 2021-01-07 11:35 (UTC) by bartus)

@swiftscythe: You can use env var like ENABLE_CUDA to gave users ability to control if build with or without cuda. I'm already doing this for some of my PKGBUILDs: e.g: blender, luxcorerender

xantares commented on 2021-01-06 12:35 (UTC) (edited on 2021-01-06 12:39 (UTC) by xantares)

could the dlib-cuda be moved to a separate PKGBUILD ?

this would avoid to install the huge cuda packages (4GB once installed) if we only use the regular dlib

xan.
