Arch Linux User Repository

you makepkg.conf is out of date

https://github.com/archlinux/svntogit-packages/blob/packages/pacman/trunk/makepkg.con

no mentions about '-fvar-tracking-fooo' flags

the filter ones in the pkgbuild is old when is already in the makepkg.conf file https://github.com/archlinux/svntogit-packages/commit/182c5b6bbeecea2c90d89d684bb0f69534b0dd4c

greetings

I have -fvar-tracking in my DEBUG_CFLAGS and DEBUG_CXXFLAGS in my makepkg.conf. So maybe some code is needed in the PKGBUILD to strip off gcc-specific command line arguments that are used here where not gcc but clang is used?

Regards.

It seems there's currently a bug between GCC and TCanny that makes TCanny completely not work at all with ASM optimizations when compiled with GCC. Details: https://github.com/HomeOfVapourSynthEvolution/VapourSynth-TCanny/issues/13#issuecomment-1107761014 It's been replicated by several people.

I think it may be wise to change the PKGBUILD to use clang for the time being. This can be done by prefixing CC=clang CXX=clang++ on the meson step (and obviously adding clang as a makedepend).

Hi sir,
arch-meson(it uses buildtype=plain in script) leads this plugin to weird behavior when use cpu and default parameters.
Please update build() function in PKGBUILD to following context(buildtype=release) to solve this problem:
build() {
cd build meson setup \
--prefix /usr \
--libexecdir lib \
--sbindir bin \
--buildtype release \
--auto-features enabled \
--wrap-mode nodownload \
-D b_lto=true \
-D b_pie=true \
"../${_plug}" \
--libdir /usr/lib/vapoursynth

ninja
}
