meson cannot find boost about aegisub HOT 4 CLOSED

What's your OS and meson version?

from aegisub.

this is on nixos linux, my build file is aegisub.nix

i guess that meson's dependency('boost' is looking for pkg-config files (*.pc)
but nix only provides cmake files for boost

nix-shell -p boost17x.{out,dev}

find /nix/store/*-boost-1.77.0{,-dev} -name '*.pc' | wc -l 
0

ls /nix/store/*-boost-1.77.0-dev/lib/cmake | head
/nix/store/1y236bbv4n0qbvf1q7zihh4kdmxxvf2q-boost-1.77.0-dev/lib/cmake:
Boost-1.77.0
boost_atomic-1.77.0
boost_chrono-1.77.0
boost_container-1.77.0
boost_context-1.77.0
boost_contract-1.77.0
boost_coroutine-1.77.0
boost_date_time-1.77.0
BoostDetectToolset-1.77.0.cmake

still a problem with latest Aegisub

cc.find_library('boost_system') still works for me

build works, but im getting runtime errors:
audio plays too fast, sounds garbled
video does not play. when i seek, the video is frozen at the current frame
same problem with different videos (they all work in mpv or gaupol)

Boost upstream doesn't provide .pc files (sad, but they seem to irrationally dislike the idea).

Instead, Meson includes a custom dependency lookup, defined here: https://github.com/mesonbuild/meson/blob/master/mesonbuild/dependencies/boost.py

You may need to define $BOOST_ROOT for that to work.

from aegisub.

so meson seems to dislike the idea of a cmake lookup of boost → mesonbuild/meson#8801

closing as "has workaround"

thanks : )
